318 THE CANADIAN ENTOMOLOGIST. 



also pale ; surface brightly polished throughout, the head small, longer 

 than wide, convex, sparsely and longitudinally strigilate throughout 

 except toward base and on the front, not distinctly punctate ; eyes 

 moderate in size, but extremely convex and pI^3minent ; antennae half as 

 long as the body, very strongly and gradually incrassate distally through 

 the outer five joints, which are also strongly compressed ; prothorax 

 extremely convex, narrower than the head and somewhat longer than 

 wide, finely and sparsely punctate throughout; elytra about one-half longer 

 than wide, more than twice as wide as the prothorax, strongly and gradu- 

 ally inflated j'josteriorly, finely and sparsely punctate and subglabrous 

 throughout, even in the subbasal impression, where the punctures are 

 simply larger but still sparse, elsewhere very minute and forming series, 

 some of which bear the' long tactile setae, and others small, more decum- 

 bent hairs, all extremely sparse ; mesosternal plate beaded anteriorly and 

 l)osteriorly, but not at the sides ; basal joint of the hind tarsi longer than 

 the remainder. Length, 1.9 mm.; width, 0.62 mm. 



Texas (Brownsville). Mr. Wickham. 



Notably distinct from the two preceding species in sculpture and 

 general appearance. 



Z. fronteralis, n. sp. — Of the same type as the preceding, but minute 

 in size and much more slender, less convex, glabrous, dark piceo-rufous, 

 the antennte black distally, the elytra piceous-black, with a broad yellow 

 band at basal fifth; legs paler, flavo-piceous; head very sparsely punctate, 

 with a few longitudinal rugae anteriorly toward the eyes, the latter very 

 prominent ; antennae very slender, scarcely half as long as the body, 

 rapidly and strongly incrassate and compressed near the tip ; prothorax 

 much narrower than the head and elongate, finely, sparsely punctate ; 

 elytra nearly twice as long as wide, more than twice as wide as the 

 prothorax, gradually and but feebly inflated posteriorly, not distinctly 

 l)unclured except some rather large but feeble and very sparse punctures 

 in the subbasal impression, which is much feebler than usual. Length, 1.65 

 mm.: width, 0.45 mm. 



Mexico (Frontera in Tabasco). Mr. C. H. T. Townsend. 



The small size and slender form of this species will readily admit of 

 identification when discovered. 



EuvACUSUS, n gen. (Anthicidtv). 



Body broader and more convex than in Vacusus, the integuments 

 opaque and densely sculiJ.tured, the elytra without trace of erect tactile 

 setae ; tempora prominent and rounded behind the eyes ; occiput broadly
