396 CASEY 



though rather closely so very near the sides ; scutellum rounded, 

 fully as long as widie, pubescent ; elytra gradually narrowed to 

 the narrowly truncate tip in apical two-fifths, the sides feebly 

 arcuate, inore strongly rounded at the humeri to the thoracic 

 angles, at the middle about a fourth wider than the prothorax ; 

 surface without impressed lines, except one along the suture 

 toward tip, minutely punctate, the punctures arranged in a few 

 alternating broad stripes, in which they are very sparse and rather 

 closely aggregated, less evident laterally, where the punctures be- 

 come slightly larger and closer and with the surface minutely 

 rugulose, the side margin finely serrate ; abdomen with long white 

 pubescence not concealing the surface, minutely, not closely punc- 

 tate medially. Length 12.0 mm. ; width ^.o mm. Arizona.

16 — Body rather narrowly elongate-fusoid, moderately convex, gla- 

 brous, polished, black, the elytra somewhat piceous, strongly 

 ffineous in lustre, with scarcely metallic lustre beneath, the legs 

 dark piceous ; head rather coarsely and strongly, somewhat 

 sparsely punctured, the lateral lobes of the front rounded but 

 almost as anteriorly prominent as the epistomal lobe ; eyes much 

 more coarsely faceted than in any of the preceding species, the 

 supra-orbital carinai fine ; prothorax nearly one-half wider than 

 long, the apex broadly sinuate, two-thirds as wide as the base, 

 the angles but slightly acute and not very much advanced though 

 not at all blunt, the sides almost evenly^but rather feebh' arcuate, 

 very slightly sinuate just before the basal angles, which are some- 

 what acute and prominent, the punctures fine and sparse, becom- 

 ing slightly coarse but still widely separated laterally, without 

 impunctate line except feebly at base; scutellum ogival, as long 

 as wide ; elyti'a very gradualh' acutely pointed and gi'adually 

 declivous in apical two-fifths, the sides feebly arcuate, abruptly 

 rounded at base to the thoracic angles, a third wider than the 

 prothorax, the punctures minute, very sparse and confused through- 

 out the width, with nine even, entire and unimpressed series of 

 moderately coarse, deep, rather well separated punctures, not at 

 all confused or larger toward the sides ; abdomen smooth, fineh"

The genus Lohonietoj^on proper includes, besides the Ameri- 

 can species above described, most of the ISIexican and Central 

 American sexually similar forms with lobed epistoma, recently 

 made known by Mr. Champion in the " Biologia." Efitra- 

 gonia and Efitragofsis are treated as subgenera in tlie table, 

 though I have but little doubt that they will ultimately be 

 regarded as true genera. The latter is, like Epi'tragus, a 

 purely South American group, only penetrating Central Amer-
