AMERICAN COMPONENTS OF THE TENTYRIIN^E 329 



produced, broadly truncate, the converging sides before the eyes 

 rather stroiigly arcuate ; prothorax about two and a third times as 

 wide as long, otherwise as in injlatus and quite as densely sculp- 

 tured ^throughout ; elytra fully a fourth longer than wide, more 

 than three times as long as the prothorax and but slightly though 

 evidently wider, unusually acutely and gradually ogival at tip, 

 the sides feebly arcuate, rounding as usual at base, the punctures 

 fine, irregular and well separated but more strongly muricate than 

 usual, becoming more closely aggregated into obscure longitudinal 

 and very faintly elevated lines laterally, the pleural impression 

 subobsolete ; abdominal segments narrowly margined with black 

 at apex, the impressions of the third segment in the female very 

 faint and subobsolete. Length 6.5 mm.; width 3. 2S mm. Cali-

It is assumed that the small impressions subequally trisecting 



the width of the third abdominal segment at apex, visible in 



some individuals, pertain to the female, for the reason that my 



only specimen having the intromittent spicule protruded is 



devoid of these impressions. Of oviformis I have a very large 



series, exhibiting but little variability, and, although the species 



adhere closely to a common type of structure throughout, I am 



therefore somewhat confident of their ' validity as expressed 



above. 



Emmenides n. gen. 



In general facies this genus is not unremindful of Mctopoiiium, 



but with the fine sculpture of Telahis. The frontal margin is 



entire and very broadly arcuato-truncate, the mandibles feebly 



cleft at tip, flat above, with a broad flat ridge externally at base, 



and the mentum has the usual small apical emargination. 



The antennas are long and slender, the eyes rather large and 



notably prominent, the scutellum short but distinct and strongly 



transverse, and the hind tarsi are shorter than the tibiaj, with 



the basal joint much longer than the last. The single species 



is the following : — 



Body oblong, parallel, convex, glabrous, shining, rather pale rufo- 

 castaneous throughout, the legs concolorous ; head broad, not 

 very coarsely but deeply and closely punctate, the sides much 

 less prominent than the eyes, strongly converging and arcuate, 

 merging gradually into the apical margin ; prothorax three-fourths 

 wider than long, much narrower at apex than at base, the sides 

 evenly converging throughout and broadly, evenly arcuate, the 

 apex sinuate, the angles right, not rounded, the side margins
