REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ 6l 



finely, sparsely punctate, the process margined at the sides but 

 only at its base between the coxae ; basal joint of the hind tarsi as 

 long as the entire remainder. Length 12.0 mm. ; width 7.8 mm. 

 New Mexico. [= Zophosis retictdata Say] reticulatus Say 



Form and general characters nearly similar but inore broadly oval and 

 less oblong, the eroded depressions of the elytra large, less nu- 

 merous and less anastomosing, the interspaces and longitudinal 

 lines shining, the erosions deeper than in any other species and 

 more abruptly defined by transversely irregular lines of close-set 

 and strongly muricate punctures; inflexed sides of the elytra 

 rather coarsely but sparsely punctured, the punctures much more 

 distinct than in reticulattis. Length 13.S-13.S mm. ; width 8.7- 

 9.5 mm. Texas (near El Paso) corrosus n. sp. 



5 — Form broadly oblong-oval, inflated posteriorly, strongly convex, 

 deep black, the anterior parts alutaceous (?) or opaque (cJ*), the 

 head and pronotum very minutely and sparsely punctate, the 

 former much more finely than in reticzdatus ; sides of the latter 

 rather broadly, subequally explanate throughout (?) or scarcely 

 at all explanate (c?) ; elytra shorter than in any other species, 

 much shorter than wide in both sexes, the longitudinal elevations 

 very faint and ill-defined, stronger in the male, most of the sur- 

 face rather strongly shining, the muricate punctures finer, less 

 close-set and not forming such distinct transverse lines as in coi'- 

 rosus ; inflexed sides of the elytra only very finely, remotely and 

 indistinctly punctulate. Length 10. 8-13. 5 mm. ; width 7.5-8.6 

 mm. Arizona (Grand Can3'on of the Colorado), — T. Mitchell 

 Prudden brevipennis n. sp. 



6 — Body oblong-oval to oblong, convex, deep black, dull and opaque 

 in lustre; head and prothorax alutaceous, faintly and sparsely 

 punctulate as in brevipennis^ the sides of the latter more narrowly 

 and more concavely explanate, the reflexed part subequal in 

 width throughout; elevated parts of the elytra strongly alutaceous, 

 the erosions rather deep, irregularly confluent, the asperulate 

 punctures fine, sparse and moderately distinct but not defining the 

 erosions, the six longitudinal lines on each elytron unusually evi- 

 dent, especially in the male ; elytra unusually elongate, evidently 

 longer than wide in both sexes, the inflexed sides sparsely and 

 sometimes distinctly punctate. Length 11. 8-13. 8 mm.; width 

 7.6-9.7 mm. Arizona (San Bernardino Ranch, Cochise Co.), 

 — F. H. Snow elongatulus n. sp. 



Body oblong-oval, smaller than in elongatulus and less convex, more 

 abbreviated, the lustre subopaque, the prothorax more trans- 

 verse, with the apex not more than half as wide as the base, less 

 concavely explanate at the sides and sometimes sensibly more 

 broadly toward base; elytra about as long as wide, the elevated 

 lines less distinct, the eroded fovejE large, rather deep, impressed 

 and anastomosing, not at all defined by the small punctures, 

 which are sparse and not definitely muricate, usually hardly
