WILLIAM G. DIETZ, M. I). 
fiftlis ( % ) from the apex; seCoiul joint of fnnicle longer than the third. Eyes 
almost round, moderately convex. Head distinctly constricted hehind the eyes, 
giving the latter the appearance of prominence; rather coarsely, but not densely 
punctured, spar.sely pubescent; frontal fovea elongate, superficial. Prothorax 
less than one-half wider than long and nearly twice as wude at the base than at 
the apex, latter scarcely constricted; sides regularly rounded; surface coarsely 
and rather den.sely punctured, evenly pubescent. Elytra oblong oval, distinctly 
wider at the base than the prothorax; sides feebly, apex more strongly and con- 
jointly rounded. Striae wide, deeply impressed, especially nearer the base , punc- 
tures moderately large and approximate, especially nearer the base; interspaces 
feebly convex, punctulate and sonewhat rugose; surface evenly pubescent, scu- 
tellum more densely so; underside of thorax finely and more remotely, abdomen 
densely and more coarsely punctured; pygidium slightly exposed (%). Legs 
slender ; femora feebly clavate, bidentate, outer cusp of middle and posterior 
feeble. Tarsi slender, claws bifid, tooth long and slender. Long. 5.5 mm.! .22 
inch. 
Hab . — Lower California; exact locality not given. 
A % specimen in j\Ir. H. Ulke’s collection, very recently received. 
Strnctnrally, this species agrees very closely with the foregoing, but 
the eves are nearly round, the elytra almost conjointly rounded at 
the tip and all the femora are bidentate. In coloration and vestiture, 
it is totally different. 
A. pervilis n. sp. — ,'Vgrees with the preceding in all particulars, except the 
following : ferruginous, underside of thorax piceous. Head not constricted 
behind the eyes, which are scarcely convex; a transverse, deeply indented line 
above the eyes. The pygidium is very little exposed. Long. 5 mm. ; .20 inch. 
Hab . — Lower California. 
A 9 specimen, received with the foregoing from INIr. H. Ulke for 
determination. It is with some reluctance that I record this species 
as distinct from peninsularu, but the strikingly different coloration, 
which is not due to immaturity, the head not constricted hehind the 
eyes and the deep, transverse indentation above the eyes, seems to 
warrant its separation, until more extensive series of s[)ecimens shall 
establish its identity with the former. 
Suhgenus Trichobarapsis. ■* 
A coarsely })ubescent species from Texas, having the prosternum 
emarginate and the seventh joint of the fnnicle continuous to the 
club, forms the type of this subgenns. The anterior and middle 
femora are bidentate, posterior with a single tooth. The tibiae are 
l)i-emarginate internally, and the armature well marked. The tarsi 
are slender; claws broad and widely sejiarate, armed with a tooth 
nearly as long as the claw.
