NORTH AMKKICAN COLEOPTERA. 
331 
This species was originally named from some small and feeble forms 
from the North, which, at first sight, are very unlike the larger forms 
from the Texan region. It is also evident that LeConte had speci- 
mens of another species along with his types as tlie so-called male is 
really that of defedus. At present the specimen is not found with 
tlie types, having |)robably been removed either by himself or Crotch. 
The larger Texan forms were described l)y LeConte as cuneus from 
a single specimen in Ulke’s cabinet. From not finding a type in the 
LeConte cabinet. Crotch subsequently named the specimens in my 
cabinet pubiventris.

.4. egeims Gory.— Moderately elongate, olive bronze, sometimes slightly 
greenish. Antennie rather slender, reaching the middle of the thorax, joints 
longer than wide, the third obviously shorter than the fourth, piceous. slightly 
bronzed, serrate from the fifth Joint: front Hat. a very feeble median impression, 
densely punctate, occiput strigose. Thora.x wider than long, sides not strongly 
arcuate, hind angles rectangular, with a well defined, slightly oblique carina, 
margin nearly straight, deHexed in front; disc convex, without median depres- 
sion, lateral oblique depressions well marked, surface transversely strigose with 
fine punctures between; scutellum transversely carinate ; elytra feebly sinuate 
at sides, slightly broader behind the middle, apices rounded, serrulate, basal 
fovefe moderate, disc slightly depressed, surface imbricate; body beneath rather 
more shining than above; prosternal lobe truncate, more or less emarginate, the 
intercoxal process narrowed at apex, propleur® sparsely punctate; metasternum 
at sides asperately punctate. Abdomen very sparsely punctate ; pygidium sparsely 
punctate, not carinate ; claws broadly toothed. Length .14 — .20 inch. ; 3.5 — 5 mm. 
Male . — Front more densely punctate, more opaque, bluish green. 
Prosternum densely punctured, hairy, the hair extending somewhat 
on the metasternum ; first two ventral segments flat or feebly ini- 
pressed at middle, slightly pubescent. 
Female . — Front slightly more convex, the punctures coarser and 
less clo.se, more shining, teneous. Prosternum not hairy ; ventral 
segments not impressed. 
Farndm/i,s.— Notwithstanding the wide area over which this spe- 
cies is distributed, there seems to be no variation, except slightly 
in color and size. Some of the narrower forms with a slight greenish 
color resemble offo.sqt.s considerably, but the structure of both antenuDe 
and claws will separate them. On the other hand, some of the forms 
oi fallax deprived of pubescence are apt to be mixed with the present 
species, and are not easy to separate without great care, but the form 
of the antenme and the flat base of clypeus in the present sj)ecies 
will render them separable.
