ROLAND HAYWAKD. 113 



at apex ; palpi fuscous; anteniife about oue-half the length of the hody, fuscous. 

 Prothorax cordate, about oue-half wider thau long, scarcely more than one-half 

 as wide at base as apex ; apex nearly truncate : median line very fine, abbreviated 

 before and behind ; transverse impressions distinct ; basal impressions small, deep, 

 nnistriate ; sides with the margin very narrowly reflexed, arcuate to behind the 

 middle, suddenly and strongly sinuate in front of the hind angles, which are 

 rectangular and carinate. Elytra very slightly wider than the thorax, oblong- 

 ovate, finely striate ; strife entire, punctate to behind the middle, the outer ones 

 very fine at apex, the fifth slightly grooved at tip ; intervals flat, the third with 

 the first dorsal puncture about one-third from base, the second about one-third 

 from apex. Head and thorax beneath brownish piceous, the abdomen darker. 

 Legs rufous. Length .15-. 16 inch ; 3.75-4 mm. 



A very distinct and curious little species, having considerable re- 

 semblance in color and markings to B. lucidum. In fact, at first 

 sight, it seems somewhat out of place in the present group, but its 

 characters are, however, such as to place it here. 



Described from three specimens, of which one is a male. Of 

 these, two were taken by Mr. F. C. Bowditch and myself in the 

 valley of the San Juan River, N. Mex., and the other at Winslow, 

 Ariz., by Mr. H. F. Wickhara. It has also been taken at Colorado 

 Springs, Colo., by Mr. Wickham. 



97. B. scintillans Bates. — Form slightly elongate, moderately convex. 

 Head and thorax nigro-teueous, shining, with more or less coppery or greenish 

 lustre ; elytra testaceous with distinct seueous reflections, and with a subhumeral 

 spot, a small quadrate spot on the third interval in front of the middle, an undu- 

 lating transverse band behind the middle, attaining the margin, a shorter one 

 between this and the apex, and a line along the suture dusky. Head not alutace- 

 ous, as wide as the thorax at apex ; palpi testaceous, darker towards the tip ; an- 

 tennfe about one-half as long as the body, fuscous, the basal joints testaceous. 

 Prothorax subcordate, slightly wider than long, narrower at base than apex ; apex 

 nearly truncate; median line fine, extending between the transverse impressions, 

 which are distinct; basal impressions small, deep, single ; sides with the margin 

 very narrowly reflexed, arcuate in front, slightly sinuate in front of the hind an- 

 gles, which are rectangular and finely carinate. Elytra about one-half wider 

 than the thorax, oblong-ovate, deeply striate ; strife entire, finely impressed to- 

 wards the apex, not closely, but deeply punctate to behind the middle, the fifth 

 grooved at tip: intervals convex, the third with the first dorsal puncture slightly 

 in front of the middle, the second about one-fourth from apex. Beneath neai'ly 

 black, shining. Legs testaceous. Length .17-. 19 inch ; 4.25-4.75 mm. 



A very pretty species. The elytral markings are often not clearly 

 defined, and are therefore difficnlt to descrilie. In some specimens 

 they are connected and so extended that in these the elytra would 

 be better described as with testaceous markings. 



In our lists this species is usually associated with scopulhium, pi- 

 cipes, etc., but the dorsal punctures are placed on the third interval,
