Coleopterological Notices. 185 



Mesosternum very sliort ; coxae widely separated, liaving a distinct trocliaiitin. 

 Metastermim moderate, the episterna moderate in width ; posterior coxfe almost 

 contiguous, just visibly separated. Legs short; femora modei-ately i-obust ; 

 tibire short, having two sets of terminal spurs, one at the inner and one at the 

 outer edge ; spurs short and rather slender ; tarsi moderate in length, densely 

 pilose beneath ; first joint elongate, penultimate very small, the basal joint 

 of the posterior about as long as the entire rema,inder, the second obliquely 

 and distinctly lobed beneath. Scutellum rather small, strongly transverse, 

 strongly rounded behind. Epipleurje moderate in width, entire, horizontal 

 behind, slightly broader and feebly inflexed toward base. Body evenly ellip- 

 tical, moderately and evenly convex. 



The posterior margins of the second and third ventral segments 

 being finely coriaceous, determines the position of this rather puz- 

 zling genus to be in the Tenebrioninffi, and the eyes being more 

 prominent than the sides of the front, together with other charac- 

 ters above given, seems to indicate that it should be associated 

 with the Diaperini, where for the present it may be placed near 

 Platydema. 



U. ovalis n. sp. — Evenly elliptical, moderately convex, somewhat strongly 

 shining, rather densely pubescent, the pubescence very fine and extremely 

 short ; piceous, legs and antennje dark brownish-rufous. Head retractile, 

 very feebly, evenly convex, not in the least tuberculate, very finely and densely 

 punctate. Prothorax nearly twice as wide as long ; apex about two-thirds as 

 wide as the base, the latter transverse with a broad very feebly arcuate median 

 lobe ; basal angles — viewed laterally — nearly right, not rounded, apical rather 

 broadly rounded, not at all prominent ; disk finely, very deeply and densely 

 punctate. Elytra rather more than twice as long as the prothorax ; sides 

 arcuate ; apex broadly rounded ; surface very finely, densely punctate, with 

 vaguely defined series of slightly larger, widely distant punctures, the series 

 without the slightest trace of impressed striae. Length 1.7 mm. 



Texas (Columbus). 



This species is widely diffused throughout the States bordering 

 the Gulf of Mexico. I owe the specimen serving as the type of 

 the above diagnosis, to the kindness of Mr. E. A. Schwarz, who 

 discovered it in considerable abundance in the locality indicated.
