tibife rather short and stout, anterior and middle strongly bisinuate internally 
and subangulate about the middle; tarsi not very slender. Long. 2.7 mm.; 
.11 inch. 
Hub. — Wisconsin, INIissouri. 
Two males in my collection. A very distinct Sjiecies ; differs from 
tectus by its smaller size, short and robust beak, and the anterior and 
middle tibiie strongly bisinuate and subangnlate along the internal 
mai-gin ; also closely allied to nifipes Lee. by the form of rostrum 
and tibite, but is smaller and the prosternum is short in front of the 
coxte. 
A. iiiolocliiiiliii* n. s]). — Oval, rufo-piceous, clothed with small, ])ale scales, 
intermixed with very fine pubescence, which do not conceal the derm. Beak 
long and rather slender, piceous, somewhat shining, punctured ; median carina 
and strife each side distinct; sparsely pube.scent ; hairs recurved. Antenufe 
slender, rufo-piceous, outer joints of fuuicle and clava darker; first and second 
joints of fuuicle long and slender, following joints rounded, club densely pu- 
bescent. Eyes feebly convex, not free. Head black, shining, punctured, occiput 
sparsely, interocular sj)ace densely scaly. Prothorax nearly twice as wide as 
long, strongly narrowed in front and constricted at the tip: base slightly bi- 
emarginate ; sides broadly rounded from the base ; surface densely punctured, 
])unctures small and superficial, each one bearing a short squamiform hair, an 
ill-defined median and lateral vittae of larger scales. Elytra oval, with feeble 
lustre, more than one-fourth wider at the base than the prothorax ; humeri 
rounded ; strife fine, impressed ; punctures large, rounded, and not closely ap- 
proximate; interspaces nearly flat, punctured; scutellar and sutural region 
darker; a broad, partially denuded jiatch each side behind the middle extending 
from the sides to about the fourth interspace and surrounded by a line of con- 
densed scales; scutellum, post-scutellar line, short basal vitta on the sixth, an 
abbreviated vitta about the middle of the fourth interspace white; underside 
pitchy-black, prothorax and pectus densely scaly; abdomen thinly pubescent. 
Legs long and slender, rufous, thinly pubescent; femora feebly clavate, all 
armed with a very small, sharp, spiniform tooth : tibiae slender, anterior feebly 
bisinuate; tarsi slender, reddish, third and last joint dusky. Long. 3 mm.; 
.12 inch. 
Hub. — Montana. Four specimens, coll. E. A. Schwarz, H. Dike 
and my own. 
Very distinct ; might, perhaps, with equal propriety be referred 
to the pubescent species, the whole habitus, arrangement of elytral 
vittte, however, place it unmistakably in the present group, while 
the conspicuous, partially denuded elytral fascia, distinguishes the 
present from all the other members of the same. 
A. riili|>e!i> Lee. — Oval, pitchy-black, antennae and legs ferruginous, thinly 
clothed above with grayish scales intermixed with fine pubescence, undersurface 
more densely scaly. Beak rather short and stout, feebly curved, slightly en- 
larged at the tip ( 'J, ), i)unctured and sparsely pubescent, distinctly carinate aud
