Prosopis cyanophila, sp. n. 



cJ. — Length about 6 mm. 



Slender, head and thorax black, abdomen dark steel-blue; 

 face below antenna? entirely deep lemon-yellow, the upper 

 edge of the yellow straight, except in the middle, where the 

 supraclypeal mark projects in the form of a triangle; 

 mandibles red at apex ; scape yellow in front ; flagellum 

 bright ferruginous beneath ; front densely punctured; meso- 

 thorax and scutellum finely and closely punctured ; upper 

 border of prothorax and tubercles bright lemon-yellow, no 

 other yellow on thorax ; area of metathorax coarsely tuber- 

 culate, its lateral margins with more or less of a double curve ; 

 tegulae piceous. Wings clear, faintly dusky apically, stigma 

 and nervures dark brown ; second s.m. very broad, receiving 

 first r. n. a short distance from its base. Legs brownish black, 

 anterior tibiae yellow in front, hind tibiae with a cream- 

 coloured spot beneath at base; basitarsus cream-coloured, 

 brown at apex, small tarsal joints brown ; abdomen elongate, 

 very finely punctured, no ventral tubercles. Runs in table
