Description: Most of the material recorded in this paper was collected by the author during his stay in Suriname from 1949 to 1955. By courtesy of Mrs. J. BONNE-WEPSTER, the author was enabled to study the Wyeomyia specimens which were collected by BONNE and BONNE-WEPSTER in Suriname and are at present in the collection of the Department of Tropical Hygiene and Geographical Pathology of the Royal Tropical Institute, Amsterdam. This material includes five holotypes and a number of paratypes.

Description: In the earliest papers on neotropical Blattidae a fair number of specimens from Surinam were recorded (LINNAEUS, DE GEER ¹), DE SAUSSURE, BRUNNER). But in the period from the beginning of this century up to now only a few scattered reports of Blattidae from that region have appeared in the literature of the subject. The present article will be the first to deal exclusively with Surinam species. The material dealt with in this paper was mainly secured by DR. D. C. GEIJSKES between 1938 and 1955. His extensive travels both in the coastal area and far into the interior of Surinam enabled him to collect all over the country.

Description: The Blattid fauna of Celebes, the Moluccas, and New Guinea, a region which from a zoogeographical point of view forms an important area of transition, is still insufficiently known. Moreover the literature on the Blattids of this region is scattered in various papers which made it desirable to give a general survey of the hitherto known species of the group from Celebes, the Moluccas, and New Guinea.\nThe present paper deals with the material of Blattidae from the region mentioned above contained in the Leiden and in the Amsterdam museums.\nI am indebted to Prof. Dr. H. Boschma and Dr. H. C. Bl\xc3\xb6te of the Rijksmuseum van Natuurlijke Historie at Leiden, and to Prof. Dr. L. F. de Beaufort and Mr. J. B. Corporaal of the Zoological Museum at Amsterdam for placing the material at my disposal. Further I should like to express my thanks to the board of Greshoff\'s Rumphiusfonds for a grant which enabled me to carry out the investigations.\nAs far as concerns our knowledge of the Blattidae in the region dealt with in the present paper, Celebes is the best known although the number of known species probably represents a part only of the existing forms. Hanitsch (1933) already came to this conclusion as he could state that few species only were caught by more than one collector. A survey of the most important collections from the region, with the names of the collectors and the authors who reported upon the material may be given here.\nBasler Naturhistorisches Museum, collectors P. and F.

Description: INTRODUCTION\nThe Blattid fauna of the Malayan subregion is very rich, accordingly since the earliest period of orthopterology students of Blattids have described and mentioned specimens from this region. Consequently the literature on Malayan Blattidae is greatly scattered, and though some of the authors did a considerable amount of work in compiling the most important contributions on the present subject, there is still much to be done in unravelling synonymy and distinguishing generic units and subfamilies.\nBrunner (1865) already described a great number of Malayan Blattidae.\nThe descriptions of new species by Walker (1868, 1869 and 1871) are very vague and full of mistakes, giving rise to a great deal of confusion.\nShelford largely restored the systematics of the group to good order by examining the species in the large collections which were at his disposal, including the types of Walker. After Shelford, Hanitsch published a large series of contributions on Malayan Blattidae, some of which (Hanitsch, 1915, 1923) contain a compilation of nearly the whole literature on this subject known at these times. In these and many other publications he also described numerous new species, but he scarcely made an attempt to arrange the unnatural aggregations of species into distinct, logical genera. Hebard (1929) on the other hand admirably succeeded in establishing numerous cases of synonymy and in describing new genera on a scientific base. Therefore it is largely due to him that the greater part of the confusion which occurred mainly in the Ectobiinae and Pseudomopinae has been cleared.\nIn the present paper an attempt has been made to continue the work along the principles put forward by Hebard.
