WILLIAM (L DIKTZ, 1\L I). 
one-tbuvth wider at the base than the prothorax ; subparallel for two-thirds their 
length and separately rounded a.t the ai)ex, deeply and coarsely striato-punctate, 
es])ecially so toward the base: interspaces somewhat convex, nigulose: under 
surface more coarsely jiubescent, pubescence less squamiform, jjygidium exposed. 
Legs and tarsi moderately slender, tliighs feebly elavate, claws rather small. 
Long, — 3 mm. , .10 — .12 inch. 
llab. — Pennsylvania, Illinois, Wisconsin, Massachusetts, New 
H ainpshire, Michigan, Oregon, Colorado, 8. California, District of 
Colnnihia. 
Occurs probably in all the Atlantic, Middle and Western States. 
Varies somewhat in coloration, but the elytra and the abdomen are 
always fen-nginons. The anterior thoracic margin is generally retl- 
dish. The legs are either bright ferruginous, or else pitchy black, 
without having observed any intermediate variations. One specimen 
in Dr. Horn’s collection from South California has the elytra! striae 
rather supei’ficial and the punctures smaller. I have no doubt of 
the identity of this species with A. h(zmatopus Boh. 
A. suturalis Lee. — Similar in size and form to sycoplianta, but a trifle less 
robust, pitchy black, elytra more or less ferruginous, tibim rufo piceous, tarsi 
paler, the beak is oi>aque, feebly striate and punctured. Antenute, head and eyes, 
as in that species. Prothorax transverse, more stroTigly rounded on the sides 
behind, narrowed in front, constricted and transversely impressed behind the 
anterior margin; surface more densely and finely punctured, base bisinuate. 
Elytra! strife not strongly impressed; punctures small, not verj’ close; inter- 
stices flat, more shining and very finely rugose; scutellum clothed with white 
pubescence ; under surface as in that species, but the pubescence is a little more 
dense and squamiform ; the tibite are a little stouter, the tarsi longer, and the 
claws larger; the tooth of the latter is also a little larger. Long. 2.7— 3 mm. ; 
.11 — .12 inch. 
Hub . — Eastern and Western States. 
The red apical blotch varies greatly in extent, leaving always, 
however, the suture and scutellar space black. Larger sized speci- 
mens with the elytra almost entirely red, may be confounded with 
A. virgo, from which the present species differs by its nnidentate an- 
terior femora, more strongly elavate thighs and smooth rostral carina. 
Fi-om sycophanta it is to be distinguished, aside from coloration, by 
the sides of the ])rothorax being more strongly rounded and the 
apical constriction, the punctures also, are less coarse and less dense, 
and the elytra more shining. 
A specimen in Dr. Horn’s collection from Iowa, while evidently 
belonging to the present sjiecies, has the ])rothorax quite coarsely, 
though very closely, punctured. The elytra are entirely ferruginous, 
with a triangular basal space dusky.
