416 THE CANADIAN ENTOMOLOGIST. 



spot at each side of the pronotum pale {^) ; elytra each with a rounded 

 yellowish spot at posterior third, barely perceptibly more distant from the 

 suture than the side margin ; legs short, dark testaceous, the posterior 

 piceous-black, though paler at the knees. Length, 2.1 mm.; width, 1.6 

 mm. Arizona (Benson), Nunenmacher. 



Belongs near Wick/ia?ni, but differs in the stronger and rather closer 

 punctures, larger eyes, with narrower interocular surface and in the 

 position of the. elytral spots, which are much more nearly on the median 

 longitudinal line. 



H. sigfiificafis, n. sp. — Oval, convex, polished, moderately finely and 

 sparsely but rather strongly punctate, strongly and closely so beneath, 

 black, the entire head and narrow pronotal side-margins pale ( ^ ), or with 

 the former picescent and the side-margins nubilous ( $ ) ; elytra with a 

 large and irregularly rounded lateral spot of red at the middle of the 

 margin, by which it is diametrally truncated, and sometimes extending 

 more than half way across the elytron; under surface piceous, rufescent 

 peripherally, the legs slightly pale, the hind femora darker. Length, 

 2.2-2.5 mm.; width, i. 5-1. 75 mm. Utah (St. George), Wickham. 



May be placed x\Q2iX plewalis, but differs in the much larger, red and 

 less sharply-defined lateral spot, and much more elongate-oval form of 

 body. 



H. concnrrens, n. sp. — Moderately elongate-oval, black or piceous- 

 black throughout, polished, finely, not closely and rather strongly punctate; 

 head ( ^ ) pale, finely punctate and pubescent throughout ; pronotum 

 narrowly, nubilously rufescent at the sides ; elytra without maculation of 

 any sort ; under surface piceous-brown, the metasternum densely punctate 

 laterally. Length, 2 0-2.3 nim.; width, i. 4-1. 65 mm. Utah (St. George), 

 Wickham. 



This distinct species may also be placed in the neighbourhood of 

 pleuralis. 



H. aterrima, n. si).--Form nearly as in the preceding but smaller in 

 size, deep black throughout ( ? ), or with the entire head and narrow, 

 abruptly-defined sides of the pronotum yellow ( r( ) ; elytra without macu- 

 lation, polished, finely, rather sparsely punctate; under surface more 

 coarsely, less densely punctate, black, the tibiae and tarsi feebly pallescent. 

 Length, i. 6-2.1 mm.; width, i. 2-1.4 mm. — Utah (St. George), Wickham. 



Difters from the preceding in its bright yellow and sharply-defined 

 anterior markings of the male, but more particularly in the feebly punctate
