AMERICAN COLEOPTERA. 273 



The facies of the species of the present genus is so remarkably differ- 

 ent from Brachi/ptenis as to indicate other more important differences, 

 while the similarity between rufipes and tinctus is so marked that their 

 close association cannot be otherwise than natural. 



The two species above mentioned although very distinct on com- 

 parison are not easy to separate by tabulation, the principal differences 

 are as follows : 



Form very robust, thorax very convex, apex distinctly narrower than the 

 base tinctus. 



Form less robust, more elongate, thorax moderately convex not narrower at 

 apex rufipes. 



The second species has the habitus of Carpophilus hemipterus, 

 while the former is much more robust than C. melanopterus. The 

 two species belong to the fauna of maritime California. 



A. tinctus Mann. — Oval, robust, piceous, subopaque, sparsely clothed with 

 short greyish pubescence, surface densely punctured, the elytra a little more 

 coarsely than the thorax. Thorax one-third wider than long, apex a little 

 narrower than the base and very feebly emarginate, sides feebly arcuate, hind 

 angles broadly rounded, base broadly arcuate and slightly sinuate each side, 

 disc convex. Elytra as broad conjointly as long, slightly narrowed toward 

 the apex, a feeble scutellar depression. Abdomen above very densely punc- 

 tured, more finely than the elytra. Body beneath densely punctured. Length 

 .16— .20 inch; 4 — 5 mm. 



The color is normally piceous above and beneath, but varieties 

 occur either entirely ferruginous or with the legs and elytra of that 

 color, {ferrugatus Murr.). 

 Occurs in California. 



A. rufipes Lee. — Oblong oval, moderately convex, piceous, sparsely cinereo- 

 pubescent, legs, antennae, sides and apex of elytra ferruginous, surface densely 

 punctured, opaque. Thorax one-half wider than long, apex scarcely narrower 

 than the base, sides moderately arcuate, hind angles broadly rounded, base 

 broadly arcuate, disc moderately convex. Elytra conjointly as wide as long, 

 very little narrowed to apex, surface punctured as the thorax. Abdomen above 

 densely and more finely punctured than the elytra. Body beneath densely 

 punctured. Length .16 inch,- 4 mm. 



All the specimens I have seen are similar in color. 



Occurs in California, especially near Tejon. 



ANTHOX^rS n. g. 



Antennae eleven-jointed, the last three joints feebly broader forming 

 a loose club, the terminal joint conical and sub-appendiculate at tip. 

 Mouth parts similar to Brachypterus, mandibles moderately prominent. 

 First three abdominal segments short, the first longer than either of 

 the two following, fourth equal to second and third together, fifth
