with a few, very minute granules towards the apex, a broad and conspicuous 

 sutural line, about one-third the length, of white scales; pygidium finely and 

 subconfJuently punctured ; pectoral canal deep, scarcely wider between the mid- 

 dle coxffi and not extending upon the metasternum, the latter with an acute 

 transverse ridge. Legs rather stout, anterior and middle tibiae subparallel, the 

 latter distinctly emarginate and subdentate above the apex, posterior a little 

 widened toward the apex with a triangular tooth and acute emargination above 

 the apex, tarsi slender, third joint broadly bilobed, fourth joint shorter than the 

 two preceding joints combined, claws with a slender tooth, scarcely two-thirds 

 the length of the claw. Length 3.0 3.25 mm. ; 0.12-0.13 inch. 



9 . Third and fourth ventral segments glabrous at the middle, fifth foveate 

 before the apex. 



Three specimens, all females, Dr. Horn's, Mr. Ulke's and Nat. 

 Mas. coll. are before me. In two specimens there is a spot of con- 

 densed scales on the third interspace near the ba.se, giving thereby 

 somewhat the appearance of a cruciform spot. The formation of 

 the metasternum distinguishes this species from all others of the 

 genus under consideration. Dr. LeConte decribes the elytral inter- 

 spaces as flat ; the}' are, however, convex. 



A. iiebulosu!^ Lee. PI. xii, fig. 14a. — Oval, dark piceous, antennae testa- 

 ceous, above thinly clothed with very fine, brownish, hair-like scales, with a 

 brassy or cupreous lustre and mottled with spots of larger, whitish scales, under- 

 side finely and closely punctured, each puncture bearing a small, oval scale. 

 Beak longer than the prothorax, rather stout, curved, finely striato-punctate 

 throughout in the male, more slender, less densely punctured and glabrous to- 

 ward the apex in the female, scrobes directed against the eye, antennae slender, 

 inserted at the middle CJ,). or two-fifths from the base (9). funicle 7-jointed, 

 joints 1-4 elongate, first joint stout, outer joints transverse, club ovate, acumi- 

 nate. Eyes moderately convex, almost entirely concealed in repose, with elevated 

 orbital margin. Head densely and finely punctured, front slightly concave; 

 prothorax more than one-half wider than long, two-fifths wider at the base than 

 at the apex, rounded on the sides, broadly but not distinctly constricted at the 

 apex, ocular lobes more distinct, anterior naargin emarginate at the middle with 

 an acute cusp each side, lateral tubercles acute, dorsal sulcus nearly obsolete, 

 surface densely and rather finely punctured ; scutel small, distinct. Elytra two- 

 fifths wider at the base than the prothorax, wider than long, feebly rounded on 

 the sides and obviously narrowed toward the apex, striae not impressed, narrow, 

 closely punctured, interstices much wider than the striae, flattened or slightly 

 convex, rugose, with a few distant, acute granules on the apical half, a transverse 

 postscutellar spot, a curved lateral fascia and some irregular spots on tlie posterior 

 half of the elytra, of white scales; metasternum subtruncate, not excavate. 

 Legs slender, anterior tibiae slender, parallel, middle and posterior a trifle wider 

 toward the apex, scarcely emarginate. tarsi slender, third joint broadly bilobed, 

 fourth shorter than the two preceding joints together, claws with a slender tooth 

 one-half their length. Length 2.0-2.25 mm. ; 0.08 0.09 inch. 



Ventral segments semi-glabrous along the middle, fifth ventral segment of 

 male with a large, transversely oval fovea, female with a small, round, well de- 

 fined impression, middle and posterior tibia? of male unguiculate at the apex.
