MONOBLASTUS. ICYONA. 333 



strong and parallel-sided, its costulse and apical carina subobsolete ; 

 lateral carinse distinct, spiracles elongate and not small. Scutelluin 

 black, punctate and hardly convex. Abdomen clear red, finely 

 punctate and pilose, with the two basal segments (except at their 

 apices) black, and the spiracles of the laterally strongly margined 

 first segment a little before its centre ; terebra very short, reflexed, 

 with the valvulae red. Legs black and with distinct white hairs, 

 the anterior tibiae and tarsi dull testaceous. Wings broad and 

 ample ; tegulae and stigma piceous, radix testaceous ; areolet 

 irregular, transversely triangular and elongately petiolate, with its 

 outer nervure, like the recurrent, broadly fenestrate ; radial cell 

 short and subtriangular ; lower wings with the nervellus sub- 

 continuous and distinctly antefurcal, intercepted far below its 

 centre. 



Length 7 milliui.

My description is drawn from the type of the species, which is 

 the only example I have seen.

The elaborate characters upon which Cameron erected a new 

 genus for this species certainly correspond exactly with all those 

 of Monoblastus, though he quite failed to mention the distinct 

 pectination of the claws. In fact so closely is this insect related 

 to M. orientalis that I should be induced to regard it as the male 

 of that species, if a distinct name had not already been proposed 

 for it. The type has the head badly crushed and the facial shield 

 dislocated, but the sculpture is identical with that of M. orientalis, 

 though the pale spots are larger and subconfluent, the flagellum is 

 a trifle thicker and the disc of the abdomen black throughout ; in 

 all other respects the two agree entirely.
