ill the male (except nevadicus) and concealed in the female; the 
tibiiB are strongly armed at the apex ; claws simple, divaricate. 
The genus ditfers from Antlionomus by the simple, divaricate claws, 
ddie species are elongate-oval in form and rather convex ; they are 
easily distinguished as follows: 
Funicle of aiitenufe 7-joiuted. 
Pubescent, femora mutic 
Suuamous species. 
Thorax trivittate, hind tibipe curved Ciirvipe;^. 
Thorax univittate, hind tibise .straight SOi’iciiliiK. 
Funicle of autennpe 6-jointed. 
Thinly clothed witli .sqnaniifonn pubescence sulsporsiis. 
Densely scaly iievadiciix. 
I-l. iiiiiiiieu.ii n. sp. — Elongate-oval, black, with dull lustre, very sparsely 
clothed with short whitish pubescence, which is a little coarser and longer on 
the thoracic side pieces. Beak about as long as the head and prothorax, moder- 
ately slender, curved and subdepressed towards the apex ; finely punctured and 
strioliite on the sides. Antenuse dark i>iceous, moderately slender; scape rather 
short, strongly incrassate and curved at its distal extremity ; funicle 7-jointed, 
first joint moderately elongate and not very stout, second joint slender, longer 
than the third ; joints 3-7 rounded, gradually wider; clava thinly pubescent and 
rather loosely articulate. Eyes large, flattened, somewhat approximate upon the 
front with the posterior margin rather free. Head convex, finely alutaceous, 
with a few remote, superficial punctures; frontal fovea large and well impressed. 
Prothorax wider than long, strongly narrowed in front, base bisinuate; sides 
rounded from the base, apex feebly constricted ; surface coarsely, but not closely 
punctured. Elytra oblong, fully one-third and rather suddenly wider at the 
base than the prothorax; sides nearly parallel for more than one-half their 
length, thence gradually rounded to the apex ; strife wide, impressed ; punctures 
moderately large and rather closely approximate; interspaces slightly convex, 
rugulose, each with a row of fine, remote punctures, bearing a fine, short hair; 
underside punctured ; ventral segments short, first and second separately less 
than one-half longer than either of the three following, which are short and 
about equal in length (%)\ pygidium fully exposed, convex, punctured. Legs 
rather slender, thighs feebly clavate not toothed ; tibiae slender, nearly straight 
and parallel, with the armature well marked; tarsi slender, third joint feebly 
bilobed ; claws slender, divaricate and simple. Long. 2.8 mm.; .11 inch. 
Hab. — Cali for ii i a . 
A unique male specimen in Mr. Dike’s collection is before me. 
It is labeled “ A. 'taorulus Lee.,” to which, indeed, it has the greatest 
resemblance, and from which it can only be distinguished by the 
simple claws. From E. adsperms, which it also resembles in form 
and general appearance, it is distinguished by its larger size, finer 
jtubescence and 7-jointed funicle.
