140 GEO. n. HORN, M.D. 



NOMASPIS Lee. 



N. sublaevis, black, sub-opaque, epistome coarsely and densely punctured, 

 front with a few, but very distant coarse punctures, and with a yellow rliom- 

 boidal spot ; thorax broader than long, sides and anterior angles broadly round- 

 ed, gradually narrowed behind, disc very finely rugose and with a few scattered 

 punctures, and a feeble median impressed line. Elytra nearly as long as abdo- 

 men, contiguous at anterior third, not imbricate, posteriorly strongly diverging, 

 surface sub-opaque, indistinctly rugose and obsoletely finely punctured ; spurs 

 of hind tibise unequal, inner spur slender, short, acute, outer spur broad, thick, 

 and very obliquely truncate. Length .?>S inch. 



Abundantly distinct from parvula Lee, by its smoother surface and 

 the character of the spurs of the hind tibia?, in the latter species they 

 are both slender and equal. 



One specimen from Fort Tejon, California. 



LANGURIA Latr. 

 L. convexicollis, black, shining, thorax rufous, head black, brownish between 

 the eyes, sparsely and finely punctured; thorax quadrate, very convex, sides 

 broadly rounded in front, sliglitly convergent behind, anteriorly feebly einar- 

 ginate, posteriorly truncate, angles rectangular. Base finely margined, and 

 edged with black, and with a short oblique impression on each side between 

 the middle and the angles. Elytra elongate, sides gradually converging, finely 

 striato-punctate, with the interstices finely wrinkled. Legs black. Length 

 .42 inch. 



Owen's Valley, California. One specimen. 



The thorax of this species is more convex and with sides more broad- 

 ly rounded than in any of our species with a quadrate thorax; the 

 thorax is also very finely and sparsely punctured, the middle of the 

 anterior margin and the whole of the posterior margin edged with 

 black. The head, except between the eyes, is also black.
