Judging from Bates' remarks in the Biologia 0. landolti is a vari- 

 able species in Mexico and Central America and it is possible that the 

 above described form is only a color variation of landolti. However, 

 my material shows no intermediate forms and the specimens are 

 either referable to landolti or tcxanus. 



Onthophagus brevifrons Horn. 



Horn, Trans. Kans. Acad. Sci., Vol. VH, p. 76. 



" Oval, slightly oblong, robust, convex. Head and thorax more 

 shining, varying in color from bluish to violet or greenish metallic. 

 Clypeus short and broad, very obtuse in front, the margin broadly 

 reflexed, surface coarsely not densely punctured, suture indistinct. 

 Front more densely and finely punctured. Vertex with a feebly 

 elevated, transverse, sinuous ridge. Thorax very little wider than the 

 elytra, anteriorly retuse, and concave at the sides, surface coarsely 

 but sparsely punctured, with finer punctures intermixed, more densely 

 punctured at the middle of the protuberance. Elytra broader than 

 long, finely seven striate, the striae obsoletely, distantly punctulate, the 

 outer striae arcuate, intervals flat, irregularly biseriately punctulate, 

 each puncture with a short, erect hair; surface opaque, finely granu- 

 late, and with slight purple lustre. Body beneath sparsely punctate, 

 abdomen with few finer punctures at the sides. Anterior tibiae 

 quadridentate, the upper tooth smaller. Length, .40 inch; 10 mm.

" This species resembles janus, but is larger, more elongate, thorax 

 more retuse in 'front and with a differently formed clypeus and 

 cephalic ornamentation." 



NEW SPECIES OF PSAMMOCHARID^. 



By Nathan Banks, 



Washington, D. C. 



The new species here described belong mostly to two of the larger 

 genera of the family, genera in which there are still numerous novel- 

 ties yet to be collected in our country, particularly in the western 

 parts.
