They have the prothoracic depressions a little more distinct than in the Texan examples 

 of 8. coactorum kindly forwarded by Prof. Chittenden. The 8. reticulaticollis of the 

 last-named author (nee Boh.), from Los Angeles, California, &c, is closely related to 

 8. hoegbergi.

10. Sphenophorus terricola, sp. n. 



Oblong-oval, robust, opaque above, black, covered with a brownish incrustation, which partly hides the elytral 



sculpture. Eostrum curved, stout, compressed, barely two-thirds the length of the prothorax, closely 

 punctate above, smooth at the sides anteriorly, angularly dilated at the apex beneath, the widened basal 

 portion shallowly sulcate up to the frontal fovea, Prothorax longer than broad, somewhat rounded at 

 the sides, bisinuate at the base ; densely punctate, except along the smooth, raised, incomplete median

line, which posteriorly intersects the oblong, depressed, more coarsely punctured, V-shaped basal area, 

 and is sometimes preceded by a shallow oblong depression. Scutellum triangular, bare. Elytra a little 

 wider than the prothorax, oblong-subcordate ; narrowly striate, the striae with scattered moderately 

 coarse punctures, which are each enclosed in a large shallow fovea, the interstices closely and finely uni~ 

 or biseriately punctate, 3, 5, 7, and 9 narrowly raised. Pygidium closely punctate, broad, in the c?, 

 narrower in the $ , furnished with a small tuft of fulvous hairs on each side at the tip. Beneath closely 

 punctate, the ventral excavation of the J long and deep. Anterior and intermediate femora each with a 

 matted tuft of long hairs at the base and some shorter hairs between this and the apex. Tibiae sinuate, 

 and fringed with long hairs towards the apex, within, the apical spur very long, the anterior pair with 

 a sharp subapical tooth on the inner edge. Anterior tarsi with the third joint very slightly widened 

 in the d .

Length 8|-9f, breadth 3±-4 millim. ( <J $ .) 



Hab. Mexico, Northern Sonora {Morrison). 



Eleven specimens, all in dirty condition. Very like 8. cicatistriatus, but with the 

 punctures of the elytral strise smaller and each surrounded by a large shallow fovea ; 

 the prothorax densely punctate, except along the incomplete raised median line ; the 

 third joint of the anterior tarsi of the male less widened. The elytral sculpture cannot 

 be seen properly till the incrustation is removed. 8. soltaui, Chittend., is a somewhat 

 closely allied form.

c? . Ventral excavation long, broad, and deep ; tibia? hollowed along their outer half within. 



Hab. Mexico l 2 (Mus. Brit). 



There is a single specimen ( 6 ) of this species in the British Museum, agreeing 

 with the type. It is a small, oblong, black form, with the surface (except along the 

 middle beneath) covered with a brownish incrustation, partly hiding the sculpture. 

 The rostrum is rather short, stout, compressed, deeply sulcate at the base above, and 

 (as seen in profile) rectangularly dilated at the apex beneath. The prothorax is longer 

 than broad densely, coarsely punctate, except along the smooth abbreviated median
