and sbinin<r toward the apex, anteniiie moderately stout, inserted Just before* the 

 middle, first joint of funicle stout, following joints of about equal thickness, 2-4 

 a little longer than the outer joints, which are not widened, club ovoidal. Head 

 convex, punctured and scaly, orbital margin not elevated, front not concave; 

 prothorax convex, less than one-half wider than long, regularly rounded on the 

 sides, sharply though not broadly constricted at the apex, dorsal channel deeply 

 im])ressed in its basal fourth, indistinct beyond, lateral tubercles inconspicuous, 

 small, a superficial fovea-like im])ression with condensed white scales in front of 

 each, surface densely and finely punctured, each puncture bearing an elongate 

 scale. Elytra nearly one-third wider at the base than the prothorax, a little wider 

 than long, feebly rounded on the sides and narrowed from the humeral callus 

 posteriorly, stri.e impressed, punctured, not concealed by the scales, interspaces 

 somewhat convex, equal, rugose, scales not condensed into spots; pygidium 

 densely punctured; tihiai nearly parallel, middle and posterior tibite feebly 

 emarginate above the apex, outer angle produced, tarsi very slender, fourth joint 

 conspicuously longer than the two preceding joints. Length 3.5 mm. ; 0.14 inch. 

 % . Last ventral segment slightly foveate near the tip; middle and posterior 

 tibite unguiculate at the apex. 



Hub. — Texa.s. A male spofinien in Dr. Horn's coll. bearino: the 

 cabinet label, "C acephalus Say," from which it differs by the " very 

 slender tarsi and elongate fourth joint and the more convex elytral 

 interstices. It is much more robust than any of the following species, 

 from winch it also differs in the absence of all elytral spots. 



A. giittaf IIK n. sp. PI. xii. fig. 3. — Oblong oval, piceous, antenna? and legs 

 rufo-testaceous, densely clothed above with small, pale straw-colored scales, va- 

 riegated on the elytra with spots of paler scales, underside densely clothed with 

 large, cream-colored scales. Beak rather slender, cylindrical and scaly nearly to 

 the tip in the male, attenuated and shining beyond the insertion of the antennae 

 in the female; antennte slender, inserted at the middle {%), or two-fifths from 

 the base ( 9 ). fii'st and second joints of funicle distinctly elongate, joints 3 and 4 

 about eijual, outer joints a little wider, club stout, ovoidal ; prothorax wider than 

 long, rounded on the sides, narrowly constricted at the apex : surface closely but 

 not very finely punctured, dorsal channel well impressed posteriorly, nearly ob- 

 solete in front, lateral tubercles very small, a transverse row of four spots and 

 base of dorsal sulcus clothed with pale scales. Elytra less than one-third wider 

 at the base than the prothorax and a little longer than wide, narrowed posteriorly, 

 strise well impre.ssed, wide, not concealed by the scales, distinctly punctured, 

 punctures small, each bearing a white oval scale, interspaces flattened, about equal 

 in width, the pale spots are arranged as follows: one near the base and another 

 at the apiex of the third insterspace, another spot on the fifth and ninth inter- 

 spaces, two-fifths from the base: pygidium closely punctured and scaly. Legs 

 densely scaly; tibise slender, middle emarginate above the apex, outer apical 

 angle acute, posterior tibia> distinctly angulate, tarsi long and slender, third joint 

 not broadly bilobed, fourth longer than the two preceding joints together, tooth 

 very slender. Length 3.25-3.5 mm.; 0.13-0.14 inch. 



■To avoid misunderstanding, the expression "'inserted before the middle" 

 means ''nearer the base," beyond the middle "nearer the apex."
