Paet I.— afkican TINGIDID^. 



In recently studying the African Tingidida, I was under the 

 greatest obligation to Dr. Yngve Sjostedt, of the Stockholm 

 Museum, for lending me typical specimens of Stal's African species. 

 Nearly all of these are here figured, and with one exception, so 

 far as I am aware, they, with the new species and genus here 

 described, constitute the first illustrations of Ethiopian Tincjidida. 

 However carefully these small insects may be described, it is almost 

 impossible to recognise them specifically — if not generically — without 

 the aid of a good figure. I have also enumerated all the species 

 known to me which have been described from Africa. I have not 

 included Madagascar, nor the other African islands. 



It is greatly to be desired that entomologists in all parts 

 of Africa would pay some attention to these interesting insects. 

 Lethierry and Severin in their Catalogue published in 1896 enume- 

 rated 335 species for the whole world. Since then Mr. Champion, 

 who collected in Central America, has for that region alone enume- 

 rated seventy-eight species, of which sixty-six were previously 

 undescribed, and required the proposal of seven new genera. This 

 will give some idea of what may be done in Africa, where at present 

 I can now only refer to twenty-six species distributed in twelve 

 genera.
