116 ME. W. F. KIRBT ON THE 



Eostrum 4-jointed, short and broad at the base; the last 

 joint conical, pointed. 



Pronotum trilobate, each lobe distinctly wider than the 

 preceding ; front lobe slightly grooved ia the middle ; middle 

 lobe more deeply, but not quite to the back, and with a shallow 

 oblique groove on each side. 



Scutelkim triangular. 



Metanotum with a short thick spine at each of the hinder 

 angles. 



Abdomen as broad as the hinder lobe of the pronotum, 

 depressed, strongly keeled beneath. 



Tegmina moderately long and broad ; costa and inner margin 

 nearly straight, the latter slightly oblique ; hind margin rounded ; 

 costal nervure only indicated at the base, but throwing off a 

 slender hairy line close to, and nearly parallel with, the costa, 

 and curving round so as to enclose a long Cell close to the basal 

 half of the costa ; subcostal rising just beyond the base and 

 throwing off another slender line enclosing a large cell close to 

 the hinder half of the costa, and then continued as a slender 

 line parallel to the hind margin ; the middle of this cell is con- 

 nected beneath by a short transverse nervure with the upper 

 outer cell formed by the median nervure, which rises near the 

 base and ramifies to form two upper and one lower cell ; the 

 upper outer cell throws out two nervures to the hind margin, and 

 is connected by a transverse nervure below with the anal nervure, 

 which latter is continued to the boundary line on the hind margin. 

 The outer nervures are apparently double, from being fringed with 

 short black bristles on each side ; towards the costa there are 

 also more scattered black bristles, and the costa and hind margin 

 are also fringed with short hairs. 



Wings with the subcostal nervure forming a long cell, from 

 the extremity of which a nervure runs to the hind margin ; 

 another nervure descends from the middle o£ the cell and curves 

 outwards to the hind margin ; and there is also a lower simple 

 nervure. 



Legs. — Eront and hind femora slightly thickened and carinated ; 

 front tibia; flattened and much widened at the extremity, which 

 is cut off square, and armed with three sharp spines on the lower 

 edge; front tarsi 2-jointed, the terminal joint consisting ap- 

 parently of one long, sharp, curved spine, but on very careful 

 examination the extremity is seen to consist of two short claws ;
