punctures only moderately coarse, uneven and very obscurely lineate 
in arrangement; abdomen fully as wide as the elytra, parallel, some- 
what finely but not closely punctate and shining. Male with a deep 
narrow impression in apical half of the median line of the fifth ventral, 
the sixth with a broad shallow apical sinus and adjoining triangular 
impression, the latter with short spiculose hairs much as in jacobina 
and allied species; female not at hand. Length 6.0mm.; width 0.85 mm.

Form more slender and elongate and rather more depressed, the entire body 
and legs bright testaceous, the abdomen piceous-black, the antennae 
fuscous; head oblong, somewhat longer than wide, the sides parallel 
and feebly arcuate, the basal angles moderately broadly rounded to the 
neck; eyes unusually small, anterior; punctures moderately coarse, 
deep, well. separated; antennae moderately stout, very distinctly in- 
crassate distally; prothorax narrow, much elongated, very much nar- 
rower than tue head, the sides subparallel, the apical angles less broadly 
rounded and obliterated than in subseriata, the punctures coarse and 
rather sparse; elytra parallel, somewhat longer than wide, about a fifth 
wider than the prothorax and slightly, though obviously, shorter, the 
punctures coarse, uneven and close-set, arranged in very uneven series ; 
abdomen as wide as the elytra, finely, rather closely punctate and only 
feebly shining. Male with a rather larger rounded impressed and gla-
