A. oriiatiilns ii. sp. Plate vi, figs. 20, 20«. 206. — Elongate siihovate, pice- 
oiis, anteniiffi and legs reddish, densely clothed with broadly oval scales, white 
and brown on the npiier surface and entirely white beneath. Beak rather 
long and slender, regularly curved and somewhat shining, punctured and sub- 
striate from base to middle with the median carina distinct. Antennae slender, 
first and second joints of funicle long and slender, latter much longer than the 
third; following joints rounded, outer ones a little wider, club dark. Eyes 
moderately convex, placed more anteriorly on the head, than usual, poste- 
rior margin free. Head wide, short and deeply immersed into the thorax, punc- 
tured and clothed with large, elongate scales; front scarcely convex, fovea obso- 
lete. Prothorax wider than long, moderately narrowed anteriorly, base nearly 
straight each side; regularly rounded from base to apex, feebly impressed in 
front; surface densely and coarsely punctured, ]iunctures deep and concealed by 
the scales; disc brown, with a narrow median line, and on the sides pearly 
white, latter with a few, scattered, brownish scales. Elytra oval, .scarcely wider 
at the base than the prothorax; sides moderately rounded from base to apex; 
strife and punctures concealed by the scaly vestiture; interspaces wide, flat; 
large periscutellar space, somewhat heart-shaped, and a large, rounded blotch 
each side behind the middle, hrown ; rest of surface pearly white, intermixed 
with scattered, brown scales, especially on the declivity. Abdomen clothed with 
piliform scales; segments 3-5 about equal in length. Legs slender, clothed with 
white scales; thighs slender, anterior with a scarcely perceptible tooth; tibife 
straight, posterior of the male almost angularly curved near the distal extremity ; 
tarsi very slender and as long as the tibirn. first joint longer than the second ( 'J, ), 
or equal to it ( 9 ) 1 l^ist joint very long, distal end and claws blackish, latter 
armed with a rather short and obtuse tooth. Long. 2.3 mm. ; .09 inch. 
Hob. — Califoniia. 
A female specimen in Dr. Horn’s and a male specimen in my 
collection. A very distinct species, not unlike dark colored speci- 
mens of pauperculus, from which, however, it is distinguished aside 
from structural differences by its bright ornamentation, more trans- 
verse thorax, elongate second joint of funicle, very long tarsi and 
short tooth of claw. For differentiation from figuratm the student 
is referred to that species. 
.A. u. sp. Plate vi, figs. 21, 21ffl. — Very similar in form, color and 
vestiture to the preceding, but a little larger, and the scales less closely applied 
to the derm, and therefore more easily removable; the beak a little longer and 
more robust at the base, with the sculpture more pronounced ; the eyes are placed 
more laterally ; the prothorax hut little wider than long, with the punctures 
smaller and more crowded ; the elytral strife, denuded of the scaly vestiture, are 
fine, but well impressed, becoming wider and deeper near the base ; the ])uuctures 
small and closely apiiroximate ; interspaces nearly flat, except at the hase, punc- 
tured and somewhat rugose; the coloration is almost identical, but less sharply 
defined, the broad white stripe dissolved into two vittfe. Legs a little darker, 
thighs infuscate about the middle; tibife longer, anterior more bisinnate inter- 
nally and the posterior of male even more strongly curved than in that species; 
the tarsi are slender, and shorter than the tihise. Long. 2.5 mm. ; .10 inch.
