NORTPI AMERICAN COLEOPTERA. 273 



is shown in some of the hairs to become erect, until in the more 

 mountainous rerjions of western North Carolina and eastern Ken- 

 tucky the erect hairs are observed to form distinct series as in hir- 

 ticula, with the hairs even longer and more conspicuous. In those 

 forms with the i-ecumbent pubescence only the elytral costie are ex- 

 tremely feeble, as the erect hairs become more evident the costie are 

 better develo[)ed. The punctuation of the thorax is also much denser 

 in those in which the pubescence is coarser. The last joint of the 

 maxillary palpi is long and cylindrical. 



As has already been noted in the generalties, those specimens in 

 which the erect hairs of the elytra are the most conspicuous are 

 females. 



Occurs in the region bounded by Massachusetts and South Caro- 

 lina, Kansas and Indian Territory. 



59. \j, albiiia Biinn. — Oblong oval, distinctly broader behind, brown, mod 

 erately shining, surface rather densely clothed with white hairs. Clypeus emar- 

 ginate, the border narrowly reflexed, densely punctured and with short erect 

 hairs, front moi-e coarsely punctured, the pubescence partly recumbent, the erect 

 hairs longer than on the clypeus. Thorax obtusely angulate on the sides, the 

 lateral margin entire, disc moderately coarsely and closely punctate, without 

 median smooth line, the white pubescence moderately long and recumbent, with 

 erect hairs intermixed. Elytra nearly as coarsely punctured as the thorax, but 

 less densely ; the usual costje, including the submargiual well marked, the pu- 

 bescence, as on the the thorax, but with few erect hairs iutermired near the base 

 and sides, more numerous in the females. Metasteruuni densely punctured, the 

 pubescence long and erect. Abdomen equally punctured over the entire surface, 

 the punctures a little coarser, but not so dense as on the metasternum, the pu- 

 bescence fine and recumbent. Pygidium densely punctured, the pubescence 

 recumbent. Claws with a moderately large, acute, median tooth. Length .60 — 

 .70 inch ; 15 — IS mm. 



Male. — Antennal club a little longer than the funiculus; ventral 

 segments slightly flattened at middle. 



Female. — Club distinctly shorter than the funiculus. 



Of this species I have examined five specimens which show no 

 special variation, except slightly in size. 



The last ventral segment is extremely short, and might almost es- 

 cape observation. It is an easily recognized species by the conspicu- 

 ous white pubescence of the surface. The last joint of the inaxil- 

 lary palpi is fusiform. 



The specimens seen have been collected in Indiana and Mississip])i. 

 It has, probably, a limited distribution.
