iH: 
Posterior tibiz with a long terminal process, base of the 
elytra trifoveate. 
B zEPHYRINUuS, Casey. Red, elytra brighter, or piceous 
with dark red head and prothorax and red elytra; legs, 
antenne and palpi, yellowish brown, highly polished, pubes- 
cence coarse. Length,2 mm. Plate X., Fig.82. Plate 
XII., Fig. 141. 41x 
Head as wide as long, eyes prominent, neck slender, feebly 
carinate; occiput feebly carinate on a line passing through the 
middle of the eyes; two small, nude, oblong fovez, mutually 
twice as distant as either from the eyes, are connected by an 
arcuate sulcus. The frontal margin is depressed between the 
coarsely punctured supra-antennal tuberculations and continu- 
ous with the simple clypeus; the vertex inside of the circum- 
ambient sulcus impunctate and bears a faint punctiform 
impression in the center at the end of the occipital carina. 
Antenne longer than the head and prothorax; first joint longer 
than wide; second smaller; second to eighth obconical; eighth 
slightly transverse; ninth and tenth gradually wider, the latter 
(4) obliquely truncate at the tip; eleventh larger, rounded at 
the base, conical at the tip, obliquely pointed, and with an 
erect cylindrical tooth at the base. Pyrothorax widest before 
the middle, as wide as long, sides arcuate, sinuate behind, con- 
verging to the base, which is three-fourths as wide as the disk 
and one-fourth wider than the neck; disk convex, median 
basal foveze deep, rounded; median sulcus feeble, sometimes 
reaching to one-third the length from the neck, but occasion- 
ally hardly perceptible; on each side of the median fovea is a 
pointed, leaf shaped elevation, limited anteriorly by the 
-arcuate, transverse, sulcus connecting the median with the 
lateral foveze. In the center of these leaf shaped elevations 
and near the base each side is a deep puncture; the lateral 
longitudinal grooves are arcuate outwardly. /ytra in some 
very feebly and sparsely punctulate, in others smooth, trifoveate 
at the base; sutural lines parallel at the base; the interval
