exact middle of the sides; antennae inserted close to apex, equi- 

 distant at their bases with the front of the eyes, 1st joint slightly 

 longer than 2nd-3rd combined, 2nd a trifle longer than 3rd, 3rd- 

 10th subequal, 11th not quite as long as 9th-10th combined. Pro- 

 thorax sliglitly longer and narrower than head, subquadrate, base 

 and apex feebly rounded, angles scarcely rounded, sides parallel; 

 base narrowly margined. Scutellum small, broad. Elytra at base 

 slightly wider than head, not once and a quarter as long as 

 head and prothorax combined; shoulders rounded, sides gradually 

 widening and narrowly margined from about the basal fourth, 

 each separately rounded. Legs slender, posterior tibiti? feebly 

 bent, two short thin spurs at their apices, the other til^ias with 

 very short spurs. Length to apex of elytra H, of abdomen 2^; 

 width I mm. 



9. Differs in having the head almost concolorous, with two 

 shallow impressions in front — a feeble carina separating them, — 

 and by having shorter antenna?.

Helgogaster parallelus, n.sp. 



9. Very elongate, subparallel, flat, shining. Black; base of 

 antennae and knees feel^ly diluted with red. Above and sides of 

 alxlomen with sparse and rather long black hairs. Almost im- 

 punctate. 



Head longer than wide, feeljly depressed in the middle, a feeble 

 elevation on each side in front, feebly corrugated at base, sides 

 and undersurface ; fove?e of undersurface deep, longitudinal, 

 narrowest and approximating in front: antennae slender, reaching 

 posterior coxse. Prothorax distinctly longer than wide, scarcely 

 the width of head across eyes, feebly constricted towards base; a 

 broad and rather sudden impression near base. Elytra ver}^ little 

 longer than head and prothorax coml^ined, but distinctl}^ wider; 

 sides gradually increasing to apex, each feebly separately rounded. 

 Length to apex of elytra 2, of abdomen 3|; width 4 mm.
