C'OLEOPTEKA. 109 



the sinuous portion having tufts of fine pale setae projecting poste- 

 riorly ; the terminal segment is lozenge-shape, slightly broader than 

 long and more acutely angulate anteriorly than posteriorly, surface 

 flat, very minutely punctulate, and carinate along the middle. Tlie 

 under surface of the head in both sexes is strongly and coarsely 

 punctate, but does not possess the erect sensitive setae. 



The species is recognizable at a glance by its parallel depressed 

 form and very large flat head. 



12. E. pertenilis n. sp. — Form very slender ; sides parallel. Pubes- 

 cence tine, short, rather dense and conspicuous on the elytra and abdomen ; 

 color throughout dark ferruginous-red ; integuments slightly rough, finely 

 and very indistinctly punctulate and nearly opaque. Head very large, 

 nearly as long as wide ; eyes large, round, not prominent, scarcely visible 

 from above ; genae very long, convergent, arcuate, longer than the eye ; base 

 broadly and rather strongly sinuate ; interocular surface nearly flat above : 

 punctures distinct and isolated laterally ; having at nearly one-half the 

 length from the base two very small shallow spongy-pubescent foveae, 

 mutually but very slightly more distant than either from the eye, from 

 which there extend anteriorly two narrow convergent rather deeply im- 

 pressed channels, connected behind the frontal ridge by a short straight 

 transverse channel equally wide and deep ; intermediate surface strongly 

 convex and somewhat abruptly declivous anteriorly; supra-antenual tuber- 

 culations not distinct, squarely angulate over the antennae, connected by the 

 feebly arcuate and rather prominent frontal ridge ; antennae very short and 

 robust, joints three to ten transverse, joints nine and ten equal in length and 

 no longer than the eighth, the former two and one-half times, the latter more 

 than three times as wide as long, eleventh slightly wider than the tenth, 

 scarcely longer than wide, conoidal, acuminate ; labrum small, deeply bi- 

 lobed ; maxillary palpi i-obust, third joint small, transversely cuneate, second 

 very robust at tip, fourth conical, finely acuminate, not twice a.s long as wide. 

 Prothorax widest slightly before the middle where it is slightly narrower 

 than the head and just visibly longer than wide ; sides at this point rounded, 

 feebly sinuate anteriorly, nearly straight posteriorly ; apex one-half as long 

 as the pronotal width and four-fifths as long as the base ; disk strongly con- 

 vex, having just before the centre a rather large oval impressed puncture, 

 and, at one-fifth the length from the base, a transverse punctiform impres- 

 sion strongest posteriorly and extending laterally and anteriorly, the arms 

 becoming obsolete before reaching the very small shallow lateral foveae 

 situated at one-third the length from the base. Elytra at base scarcely per- 

 ceptibly wider than the head ; sides nearly parallel. and very feebly arcuate ;. 

 disk nearly one-fourth longer than wide, moderately convex : sutural striae 

 strong, not very close, feebly arcuate, lateral very short, oblique and narrow ; 

 humeri rather prominent. Abdomen at base very slightly narrower than 

 the elytra; sides distinctly divergent posteriorly and straight, so that the 

 third segment is slightly wider than the elytra and quite as wide as the head ; 

 border rather strong; surface narrowly convex ; first three dorsal segments-
