13. HEMIPTERA. 



;> Gerridae, Corixidae and Notonectidae 



by 

 G. W. KIRKALDY. 



The Ethiopian Hemiptera of the three families here discussed are very little 

 known, STAL describing only thirteen species in all, in his Hemiptera africana (1865), 

 while the present total is less than fifty. 



No species have, I believe, been hitherto recorded from Kilimandjaro, the 

 nearest locality being Zanzibar, from wich place, with Quilimane - - further south, in 

 Portuguese East Africa - - GERST ACKER recorded a few species in 1892. (Jahrb. 

 Hamburg. Wiss. Anst. IX (2). 45 58). 



According to our present knowledge, the Ethiopian continental Hemiptera are 

 very uninteresting from a distributional point of view, the same species often exten- 

 ding all over the continent, and, in the case of the aquatic forms, into Madagascar 

 and the neighbouring islands as well. 



Dr. SJOSTEUT has collected 292 specimens in all, of which 231 are adults and 

 61 nymphs; 1 these are referable to 21 species & 13 genera. One genus and 2 species 

 are described as new. 



Gerridae. 



Liiuno^omis liypoleucus (GERST.). 



Gerri* hypuleuca GERST. 1892 op. cit. 55. = Tenagogomts trixfrialus DE CARLINI 

 1895, Ann. Mus. Genova (2) XV. 1 H. (nov. syn. !) - Ten specimens from Usambara 

 Mombo, and Tanga (June). DE CARLINI must have identified GERSTACKER'S species 

 from the description, as his type is an almost exact replica of GERSTACKER'S. 



Limiiogouus aogyptiacus (PUTON). 



Gerrift cegyptiaca PUTON 1890 Rev. Ent. IX. 228. = Tenagogonus bottegoi DE 

 CARLINI 1895 1. c. (nov. syn. !). Ten examples (7 macropterous and adults and 3 

 nymphs) from Kiliiiiinnljnro (Sep. 22) and Tanga. His little species is very like L. ni-
