median basal fovea and extending one-fourth of the length 

 from the neck. The arcuate transverse sulcus limits each 

 side of the median fovea, a leaf-shaped elevation, incHning 

 backwards, and surmounted anteriorly by a sharp-pointed 

 tubercle; behind, and between this and the base is a 

 small fovea. The lateral foveas are deep, funnel shaped, 

 near the margin, with the usual outwardly arcuate sulcus; 

 behind and outside of the lateral fovea is a pointed tubercle, 

 causing the irregular situation of the lateral margin. Elytra 

 convex, coarsely, but not densely, punctured, the punctures 

 shallow but conspicuous. The shoulders are remarkably high 

 and angular, with a blunt tubercle; sutural lines paralle'l, sharp, 

 the discal lines short, very fine, one-fourth long, on a shght, 

 longitudinal depression. The basal foveolse are three in 

 number on each elytron. Abdomen impunctate, the basal fovea 

 deep, carinas obsolete, short; the basal segment is slightly 

 longer than the fourth, and as long as the second and third 

 together. Last ventral with deep rounded impression. 



Habitat. Placer county, California. Discovered by Mr. 

 Charles Fuchs. 



B. ALBiONicus, Aiihe. Slender, narrow-shouldered, convex, 

 body piceous-black or brown, elytra red, legs and palpi paler. 

 Lenth 1.7 to 1.9 mm. Plate X., Fig. 84. 



Head as wide as long, front concave between the prominent 

 antennal tubercles, and anteriorly continuous with the clypeus, 

 posteriorly limited by the circumambient sulcus, which ends 

 near the base in a large, round, nude, fovea; vertex with a 

 conspicuous oblong impression in the center, a minute hemis- 

 pherical tubercle at the base; edge of lateral border rounded, 

 not carinate, the frontal tubercle crossed obliquely by a short 

 channel. Autennce. as long as the head and thorax; first joint 

 cylindrical, slightly concave above, and convex beneath; 

 second not narrower, obconical; second to sixth rounded, 

 oblong, gradually smaller; seventh and eighth as wide as 

 long, obconical; ninth and tenth transverse, obconical, rounded; 

 gradually wider, not longer; eleventh as long as the three
