CREMASTOCHILUS LEUCOSTICTUS BURM-MALE AND 



FEMALE. 



BY CHAS. LIEBECK, PHILADELPHIA, PA. 



[See Plate VI, Figs. 13 and 14.] 



Two specimens, male and female, of this very rare species 

 were received by courtesy of R. J. "Weith, of Elkhart, Ind., 

 that " were taken in Clarendon county, South Carolina, about 

 60 miles from Charleston, near the Sautee River, sometime be- 

 tween the 1 and 9 of August, 1896. The specimens were fly- 

 ing together in a broom -grass clearing near a swamp." 



The male shows the most curious departure from the gen- 

 eral appearance of the other species of Cremaatochilus, the up- 

 per surface of thorax and elytron being covered with a dense 

 pubescence, the base of head, two-thirds of thorax bordering 

 side margins, and entire margin on upper surface of elytron 

 being yellowish white (as shown in plate) the pubescence of 

 the remaining portions being a dense, velvety black, though 

 not so heavy as the whitish. 



The female is entirely devoid of pubescence, black, shining. 



The first three ventral segments of male are strongly, longi- 

 tudinally depressed at middle ; the anterior tibue, though 

 bidentate externally as in the female, the upper tooth is incon- 

 vspicuous, the apical much recurved, not so long nor acute as 

 in the female ; the apex strongly notched at middle, inner 

 edge of emargination resulting in short, acute tooth ; inner, 

 apical edge of tibia? being abruptly incurved from midway be- 

 tween upper and apical teeth. 



In the female the apex is obliquely straight to point of api- 

 cal tooth, though very feebly sinuate. 



The punctuation of head, thorax and pygidium of male is 

 sparser and finer than in the female, that of scutelluin much 

 more numerous and finer, the elytron being about equal in 

 both sexes. 



It seems rather surprising that no record is given of the 

 male to date, Buruieister, Handb. III. p. 677, ISlU.liusing his 

 description on a female specimen, and Dr. Horn, Proc. Am. 

 Philosophical Society, 1879, Vol. xviii, redescribing the spe- 

 cies from a unique female taken in Maryland by Mr. Ulke.
