NORTH AMKRICAN COREORTERA. 
221 
A. ebeiiiniiiii u. sp. — Robust, ov’ate; l)lac.k, with a faint seneous lustre and 
rather conspicuously clothed with wdiite pubescence, which is more dense on the 
under surface. Beak long and slender, feebly (uirved, punctured, scarcely striate. 
Antennse long and slender, .scape and first joint of funicle rufo-testaceous, re- 
mainder rufo-piceous; first joint of funicle long, not very stout, second joint 
longer than the third, outer joints scarcely wider, club rather loosely articulate. 
Eyes somewhat prominent, convex, posterior margin free. Head convex, occiput 
impunctured, front finely punctured and pubescent, especially between the eyes, 
frontal fovea elongate, rather deep. Prothorax fully one-half wider than long 
and nearly twice as wide at the base than at the apex, latter scarcely constricted ; 
sides regularly rounded from the base, latter biemarginate ; surface densely and 
rather coarsely punctured, punctures subcoufluent on the sides, each bearing a 
whitish hair; scutellum oval, densely pubescent. Elytra shining, one ft>urth 
wider at the base than the prothorax; oval, sides feebly rounded; striae im- 
pressed, punctures round, small and closely approximate; interspaces slightly 
convex, each with about three irregular rows of fine, piliferous punctures; pu- 
bescence evenly distributed, except a small intra-humeT-al spot, which is more 
densely pubescent; underside densely punctured, pubescence scarcely as long as 
above; pygidium fully exposed, punctured. Legs long and slender, thinly pu- 
bescent; femora slender, feebly clavate, armed with a spiniform tooth; tibiae 
long and slender, sinuate internally, aiitei’ior and middle curved inward near 
tbe apex, posterior straight ; tarsi slender, first joint of anterior almost twice as 
long as the second; claws armed with a long slender tooth. Long. 3.5 mm.; 
.14 inch. 
Hab . — Lower California; exact locality not stated. 
A % and 9 specimen in Mr. Dike’s collection, who received it 
very recently from the above locality. 
The mesosternum is moderately wide between the coxte, where it 
ends in an elevated, transverse ridge, and slojtes very gradually in 
front. The third and fourth ventral .segments are of e(jual width, 
and the fifth distinctly longer than either ; the pygidium is freely 
visible from below. 
This species, although very distinct, is closely allied to fiavicornis, 
nigrinns and albopiloms. It resembles fiavicornis so closely that, if 
viewed from above, it cannot be distinguished, except by its somewhat 
greater size ; the abdominal formation, however, is strikingly different, 
the beak, legs and tarsi much more slender; the first j'oint of the 
anterior tarsi twice as long as the second, while equal in fiavicornis. 
From the next species it differs by its being more robust, the beak 
more slender, thorax less coarsely punctured, the femoral tooth spini- 
form, the anterior and middle tibim curved near the aj)ex, and the 
more slender tarsi with the first joint nearly twice the length of the 
.second. The elytra, also, are a little more strongly striato-punctate, 
and the ]nibescence much more conspicuous than in that species.
