REVISION OF THE TENEBRIONID^j OF AMERICA, 



cdov entire and straight. Last joint of antennae rounded at tip. Strias feebly impressed, 

 interstices flat, smooth. The form of mentum is move nearly allied to impreasa, being 



scarcely broader than long-, rather strongly punctured, and with a groove; on each side, 

 the lateral lobes are not distinct. 



Length ,36-.42 inch. 



Occurs in Northern California. 



U. punetulata, Leo., New Species, p. 124; cava, Lee., (ibid). 



The two species above cited are united under the name most applicable to them. The 

 differences of sculpture are but light and vanish in the larger series now at my disposal. 

 The form is elongate oval, sub-parallel, as in the last species. Its color is uniformly fer- 

 ruginous. The thorax usually parallel behind the middle. Epistoma very feebly emar- 

 ginate. Last joint of antennas rounded at tip. Femora with entire groove. Interstrial 

 spaces of elytra rather densely punctured and feebly convex. 



Length. .28-.33 inch. 



Texas, Louisiana, and Florida. 



In the preceding short descriptions only the more important and peculiar characteris- 

 tics of each species noted. The species of [Jloma have a remarkable resemblance to each 

 other, and the continuous repetition of similar forms of expression has here, as elsewhere 

 in this paper, been deemed altogether unnecessary. 



ETJTOCHIA, Lee. 



Eutochia, Lee., Class. Col. N. A., p. 288. 

 Delopygus, Eee., New Species, p. 129. 



On renewed examination the differences between these two genera, appear to be so 



slight as to warrant their union. The opipleunc of the elytra do not extend to the tip in 



either genus, and the very slight difference in degree of serration of the anterior tibiae is 



barely specific, and what might be expected to occur in species of different size. 



E. picea, Mels., (Uloma) Proc. Acad. 3, 94; Lea, (Eutochia) loo. cit. 



Black and shining, oval, convex. 



Length .33 inch. 



Occurs rather abundantly in the Middle States. 



E. orenata, Lee, (Delopygus) New Species, 129. 



Smaller, more elongate and less convex than the preceding, brownish in color, with 



the sutural and lateral margins of elytra paler. 



Length .22 inch. 



Occurs in Texas.
