OCHODiEUS MANDIBULARIS, new species. 



Oval, pale ferruginous. Meutuiii elongate, convex, only impressed 

 nt apex. Prosteruum short, mandibles strongly but obtusely angu- 

 lated ou exterior margin just before middle. Clypeus with rounded, 

 simj)le margin; at base with a strong acute horn; frontal suture indis- 

 tinct. Front sparsely, moderately, finely punctate, not rugose; vertex 

 without ridge. Thorax densely punctato granulate, a round impression 

 at side and median line impressed at basal half. Elytra striate; stri;e 

 punctate; intervals feebly convex, punctate; sutural angles obtuse. 

 Ventral surface sparsely punctate. Femora simple; hind tibia^ slen- 

 der, strongly fimbriate; first tarsal joint as long as the three following, 

 slender, slightly curvate. 



Length, 7 mm. One example, collected July 10 at Wiuslow, Arizona 

 (Wickham). 



Type.—^o. 561, U.S.N.M. 



Kesembles O.ffontalls, LeConte, in form and color, but is larger and 

 distinct by the arcuate clypeus, the dentate mandibles, the strong 

 frontal horn, situated higher up on the front than the small clypeal 

 tubercle in 0. frontaJis., and the total absence c»f vertical carina. I 

 have seen an exactly similar specimen from Las Cruces, New Mexico, 

 in the collection of Messrs. Hubbard and Schwarz. 



BRADYCINETUS MINOR, new species. 



Dark ferruginous ; head, margins of thorax and elytra, suture, tibia^. 

 and tarsi darker. It differs from 7>. horuii, Eivers, in possessing a 

 larger antenual club; clyj)eus and fiont more narrow in proportion to 

 their length, the former with margin less rounded, subangulate at the 

 sides; thorax more shining, somewhat more sparsely punctate; scu- 

 tellum more narrow aiul smooth; elytral striiii distinctly more coarsely, 

 less closely punctate; intervals narrow, convex. Hind tibiiie, spurs, 

 carina) of head and thorax, the form and lateral margin of the latter 

 exactly as in the female of B. hornii. Middle tarsi with first joint as 

 long as the two following together (in B. hornii, as the three following). 



Length, 7.5mm. One female collected by Mr. E. A. Schwarz at San 

 Diego, Texas, May 26, 1895. 



T t/pe.— ^o. 5G2, U.S.KM. 



Bolhoceras furcins and B. fume/actus of our lists have the eyes com- 

 pletely and broadly divided and should not be congeneric with B. laz- 

 (tru.s, Fabricius. 



GYMNOPYGE, ne^A^ genus. 

 (Groni) DidnJonycliini.) 



Mouth parts, ventral segments, and cox?e of same structure as iu 

 Dichelonycha. Elytra short; humeral umbouo prominent; base con- 

 jointly, broadly emarginate; side margins expanded vertically or
