sesses striking sexual characteristics, the female being readily told 

 from male by annulate antennae, and less wedge shaped body. 



This longicorn is extremely rare and very local, evidently prefer- 

 ring the highest peaks of mountain ranges. Mr. Ernest Shoemaker is 

 the only local collector fortunate enough to take the species, cap- 

 turing one male on top of Whiteface Mt., Adirondack Range, N. Y., 

 July 13, and one beautiful green female taken on blackberry blossoms 

 at Slide Mt., Catskill Range, N. Y., July 4. Other records are Mar- 

 quette, Mich., June 28, in wash up on shore of L. Superior (Sherman), 

 Eagle Harbor, Mich. (Le Conte), Mt. Graybeard, N. C, July, on 

 rhododendron flowers (Van Dyke).

Head and thorax bronzed black, deeply and confluently punctured. Head 

 with a median sulcus in front, carinate on each side from below the antennae 

 to mandibles. Thorax scabrous, with antebasal transverse ridge, narrower 

 in front than behind, a median depression on the anterior half, anterior portion 

 somewhat constricted, hind angles rather prominent, produced by the lateral 

 depression, on each side at the middle is a prominent spine-like protuberance.

 humeri prominent ; scutellum black. Underside black or brassy black with 

 very short whitish hairs, finely rugose. Legs brassy black, pubescent ; tibiae 

 somewhat rufous basally. Male antennae as long as body ; female antennae 

 reach to one third from tip of elytra, hind angles of thorax more produced, 

 the lateral protuberances longer and more pointed and body more robust than

Summits of the Black Mts., western North Carolina, June 26- 

 July II. 



Ten specimens of this most beautiful Anthophilax were taken by 

 Mr. Beutenmuller and Dr. Van Dyke on the balsam fir {Abies 

 frazcri), one female being found ovipositing in same.. 



I have had the privilege of examining types in the American 

 Museum and am fully convinced it is distinct. The characteristics 

 given in the key make its separation easy. Also, as Dr. Van Dyke 

 points out, it can not be regarded as a geographical variety of viridis, 

 the species it most nearly approaches and of which a specimen was 

 taken in the same locality only three miles away.
