LeConte.] 430 [Feb. 1, 
138. Conotrachelus coronatus, n. sp.—Blackish, thinly clothed 
with very fine brownish-gray pubescence and scattered pale clavate bristles, 
with markings of dense fine white scales. Prothorax and elytra tubercu- 
late ; the former as long as wide, channeled, rough, with the sides straight, 
angulated and suddenly narrowed near the apex; there are four large 
apical tuberosities, and two discoidal ones, besides the lateral protuberance 
just mentioned ; the anterior constriction is very deep and there is also a 
transverse impression behind the lateral and discoidal tuberosities ; a narrow 
white vitta extends from apex to base each side mid-way between the dor- 
sal channel and the sides; these lines are connected with others on the 
base of the 3d elytral interspace. Elytra sub-triangular, humeri prominent, 
rounded. Strise composed of large punctures, interspaces wide, alternately 
interrupted with black tubercles bearing reclinate clavate bristles ; at the 
base of the 3d interspace is a short white line ; a large marginal spot, pointed 
interiorly behind the humerus, is also clothed with dense small white 
scales ; behind the middle is a band composed of four small spots on the 
Ist to the 4th interspaces, and a small spot near the tip formed of pale 
scales. Legs long, thighs indistinctly annulated and sprinkled with white 
hairs, acutely unidentate. Under surface very coarsely punctured. Length 
9 mm.;.12 inch. 
Enterprise; one specimen. The head is coarsely cribrate; 
the beak bent beyond the middle, not longer than the head 
and prothorax, thicker than in any other species known to 
me, with deep broad strise, and carinate along the median 
line. Antenne situated near the end. The mesosternum is 
protuberant. This species belongs to Division II, of my 
arrangement, and should be placed before C. tuberosus, (Lec. 
Rhynch., 233), to which (apart from coloration) it has little 
resemblance. The femoral denticle is obsolete, but the tooth 
is acute and prominent. 
139. Acalles wemtrosus, n. sp.—Very obese, blackish, clothed 
with appressed gray and brown scales with intermixed clavate bristles. 
Head with the occiput clothed with yellowish-gray scales. Prothorax 
deeply and broadly chanueled, twice as wide as long, rounded on the sides, 
uniform blackish brown. Elytra truncate at base, basal angles obtuse not 
rounded, sides obliquely widened, then rounded obliquely to the apex; 
there is a broad basal band occupying one-third the length of dirty gray 
scales, and some indistinct fasciate markings of the same color, behind the 
middle; the strie:are deeply impressed, and the interspaces moderately 
convex. Mesosternum broadly emarginate, as in A. pectoralis (Lec. 
Rhynch., 244). Legs clothed with dirt-colored scales. Length 4.3 mm.;

Enterprise; May, one specimen. More ventricose than
