ART. 22 NEW CEEAMBYCID BEETLES FISHER 75 



This species is allied to spinicauda Schaeffer, but it differs from 

 that species in having the pronotiim ornamented with a longitudinal, 

 median, white, pubescent vitta, and the tips of the elytra not acutely 

 spinose at their outer angles. 



ACREProOPTERUM PILOSUM, new species 



Elongate, rather narrow, and subparallel ; above and beneath red- 

 dish brown, rather densely clothed with brownish-yellow pubescence, 

 with a few paler hairs intermixed, and the elytra ornamented with 

 dark-brown pubescent markings. 



Head in front nearly twice as wide as long, slightly convex, 

 broadly concave between the antennal tubercles, which are widely 

 separated and strongly elevated, coarsely, sparsely, irregularly punc- 

 tate, densely clothed with long, recumbent, brownish-yellow pubes- 

 cence, with numerous long, erect, hairs intermixed; eyes small, 

 coarsely granulated, deeply emarginate, and separated from each 

 other on the top by one and one-half times the width of the upper 

 lobe. Antenna slightly longer than the body, pale yellow, joints 

 slightly darker at apices, sparsely clothed with short, recumbent and 

 erect, whitish pubescence, and moderately ciliate beneath; first joint 

 robust, short, oblong, without a cicatrix at apex, slightly longer 

 than the third joint, which is distinctly shorter than the fourth, the 

 following joints gradually diminishing in length. 



Pronotum feebly wider than long, subequal in width at base and 

 apex, and widest at middle; sides arcuately rounded; disk even, 

 moderately convex; surface rather densely, coarsely punctate, with 

 a small, smooth, glabrous, medium spot, rather densely clothed with 

 short, recumbent, brownish-yellow and whitish pubescence, with a 

 few long, erect, hairs intermixed. Scutellum as wide as long, tri- 

 angular, narrowly rounded at apex, densely clothed with pale yellow 

 pubescence, except the middle, which is glabrous. 



Elytra three times as long as pronotum, and at base slightly 

 wider than pronotum at middle; sides nearly parallel to behind 

 middle, then arcuately narrowed to the tips, which are separately, 

 narrowly rounded; disk feebly, broadly, transversely concave in 

 front of middle, with a feebly elevated gibbosity on each elytron near 

 the base; surface rather densely, irregularly punctate, the punctures 

 coarse on basal halves, but becoming finer and more distant toward 

 the apices, densely clothed with short, recumbent, brownish-yellow 

 and whitish pubescence, with numerous long, erect hairs inter- 

 mixed, and each elytron ornamented with dark brown pubes- 

 cence as follows: A short, narrow, oblique fascia behind humerus, 

 extending from basal gibbosity to sutural margin, a very broad, 

 oblique fascia at middle, extending from sutural margin to the
