224 Mr. W. L. Distant on Dinidorinse, 



Basicryptus negus, sp. n. 



Ochraceous, unicolorous ; membrane greyish, with the 

 nervures fuscous. 



Antenna? pale luteous; second, third, and fourth joints 

 almost subequal in length, fifth longest. Head long, the 

 lateral lobes a little divergent at apices, their margins up- 

 wardly reflexed. Pronotum rugose, sparingly punctate, 

 convex, without any central ridge, the lateral angles sub- 

 acutely rounded, the anterior lateral margins strongly serrate. 

 Scutellum rugose, scarcely so at ap?x, darkly and sparingly 

 punctate. (Jorium sparingly punctate, the punctures in some 

 places black and in small clusters. Body beneath and legs 

 sparingly punctate. 



Long. 16-20 millim.; max. lat. 10-12 millim. 



Bab. Arabia; Hadramaut (Dent Exped. } Brit. Mus.) ; 

 Abyssinia (Coll. Dist.). 



Apparently most nearly allied to the West-African species 

 B. ruyosus, Fabr., from which it differs by the non-ridged 

 pronotum &c. 



Two Abyssinian specimens in my own collection reach the 

 maximum in size.
