(lie biemarginate internally, ]>osterior of male distinctly curved, of female nearly 
straight: jiygidinm freely exposed in the male, feebly so in the female. Long. 
3.5 mm. ; .14 inch. 
Hab . — Colorado. 
A male and female specimen in my collection only very recently 
received. This species resembles camis very closely in form and 
coloration ; it differ.s, however, by its greater size, smaller and more 
densely placed scales, the elytra more gradually rounded to the apex, 
the pygidium more freely exposed, and the hind tihite of the male 
strongly eurv'ed ; the fifth ventral segment is longer than the pre- 
ceding in both sexes, esjtecially the female. 
A. rtocipieiis Lee. — Elongate-oblong, pitchy-brown, antennaj and legs fer- 
ruginous, densely clothed above and beneath with large, oval, grayish white 
scales, which, however, on the abdomen become piliform. Beak long, curved and 
moderately slender, shining, rather coarsely punctured near the base, three ill- 
defined, elevated lines. Antennae somewhat stout, second joint of funicle elon- 
gate, slender and longer than the third, which is a trifle longer than the fourth, 
club dusky. Eyes almost flat, posterior mai'gin .slightly free. Head convex, 
punctured and densely squamose; an impressed frontal line extending upon the 
base of the rostrum. Prothorax one-third wider than long, sides feebly rounded, 
subparallel behind, strongly narrowed and distinctly, though not suddenly con- 
stricted at the apex ; surface densely, though not coarsely itunctured, indistinctly 
trivittate. Elytra a little wider at the base than the prothorax, oblong-oval, 
almo,st parallel on the sides, gradually rounded to apex behind, coarsely sti iato- 
punctate, striae broad and deep, punctures large, oblong and closely approximate ; 
interspaces convex, roughened ; with the scaly covering intact, the latter appear 
wide and flattened, and the striae, and punctures not entirely concealed. Legs 
moderate, femora feebly clavate, anterior feebly toothed ; tibiae slender, anterior 
and middle slightly bisinuate internally, posterior of male regularly, but not 
strongly curved ; tarsi slender. Long. 2 — 2.2 mm. ; .08— .09 inch. 
Hab. — Texas, Kansas, Oregon, Washington. 
The pygidium is more or less freely exposed, and the fifth ventral 
segment longer than the fourth in both sexes, though more markedly 
so in the male, while it is foveate in the female. In well-marked 
specimens a j^osterior pale vitta on the fourth and an anterior one on 
the sixth interspace, as well as a post-scutellar line are more con- 
spicuous ; the darker, lateral space is generally ill-defined. 
Lee.— Closely allied to the preceding species; elliptic. ]>itchy- 
browu, densely clothed with very large, broadly oval, and uniformly white 
scales; it differs as follows: Beak more slender and shining, more finely sculp- 
tured, slightly widened and somewhat depressed at the apex. Prothorax but 
little wider than long, regularly rounded from base to apex, latter not constricted. 
Elytra more broadly rounded on the sides; strise and punctures still coarser; 
punctures more transverse and very narrowly separate. Legs, especially the
