AMERICAN COMPONENTS OF THE TENTYRIlNyE 519 



ing combined; front not bisinuatc, with a large and evenly para- 

 bolic epistonial lobe ; eyes convex, prominent and coarsely faceted, 

 with short and very Hne supra-orbital carinx which are not bor- 

 dered by a depressed area ; prothorax short, broadly and deeply 

 sinuate at tip, with the angles right and more or less blunt ; elytra 

 with coarse and confused punctuation throughout ; tarsi with pads 

 of short dense pubescence beneath. Atlantic South America. 

 [Type E. brevicollis n. sp.] Eunotiodes n. gen. 



Presternum deflexed and vertical behind the coxai, not in the least pro- 

 duced, the mesosternum with a small and feeble indentation re- 

 maining as a vestigial character; epistoma between the oblique 

 sutures very broad, trapezoidal, the apex broadly and rectilinearly 

 truncate; last antennal joint smaller than the tenth, oval; eyes 

 only feebly convex, rather coarsely faceted, the carinas and vertex 

 as in Eunotiodes ; prothorax not abbreviated, sinuate at apex, 

 with acute and more or less prominent angles ; elytra with coarse 

 and confused punctuation throughout, rapidly narrowed and acute 

 at tip; tarsi slightly grooved beneath except toward base, with 

 short, stiff sparse spinules, not at all pubescent beneath. Atlantic 

 South America. [Type O.farctiisw. sp.] Omopheres n. gen. 



Eptirago^sis, which in the body of the present paper is treated 

 as a subgenus of Lohometofon^ is here regarded as a distinct 

 genus, a course that would be necessary in any event in order 

 to compare it with other South American generic types. The 

 genus Epitragiis has been alluded to in the present paper under 

 the head of rigens (p. 381), and by Mr. Champion in the '* Bio- 

 logia." 



The genus Pareptlragus is represented by the following 

 species : — 



Moderately stout and convex, polished, dark castaneous, the pubes- 

 cence very short and sparse, fulvous and inconspicuous, more 

 noticeable near the eyes ; head moderate, not very coarsely, 

 sparsely punctate, more closely near the eyes and on the trans- 

 versely tumid epistoma ; prothorax nearly one-half wider than 

 long, moderately narrowed at apex, the sides gradually converg- 

 ing and arcuate anteriorly, becoming parallel and feebly arcuate 

 toward base, the basal angles right, not blunt but not at all prom- 

 inent, the apical obtuse and blunt; surface broadly, moderately 

 convex, impressed at the base near each side, more or less finely, 

 very sparsely punctured, with an obsolescent impunctate area 

 medially, more coarsely and closely punctate only very near the 

 sides and in the basal impressions ; scutellum semi-circular ; elytra 

 three and one-half times as long as the prothorax and nearly 

 a third wider, gradually ogival and acute behind, the sides 

 feebly arcuate, strongly rounded at base to the thoracic angles,
