Body nearly similar in form and coloration to the preceding, the head and 
abdomen blackish, the elytra brighter rufous and less clouded; head 
finely, less closely punctate, similarin form but with the eyes evidently 
larger, more obviously wider than the prothorax, the latter very dis- 
tinctly wider than long, nearly parallel at the sides, the angles moder- 
ately rounded; elytra about as long as wide, a third wider and three- 
fifths longer than the prothorax; gular sutures broadly arcuate and 
slightly impressed, nearly as in gulare in form, the under surface of 
the head more coarsely, closely and subscabrously punctate. Median 
process of the fifth segment broader, nearly half as wide as the sinus, 
its apex truncate, becoming only just visibly sinuate toward the middle, 
its lateral angles rather broadly rounded and with the sides becoming 
parallel only at the base; fimbriate sides rather strongly curved, each 
with about six or seven porrect black spinules, surface with a sparse 
arcuate series of bristles before the process. Length 3.4 mm.; width 
0.65 mm. California (probably the middle coast region) ..distans n. sp. 
19— Head narrow, somewhat longer than wide and not wider than the 
prothorax in the female, the sides long, straight and parallel behind the 
moderately developed eyes, the basal angles moderately rounded. Body 
slender, the anterior parts finely, sparsely punctured and polished, 
piceous-black, the abdomen blackish, the elytra paler and brownish- 
rufous; prothorax only just perceptibly wider than long, nearly par- 
allel and straight at the sides, the angles rather broadly rounded; 
elytra relatively much smaller than usual, about a fourth wider and | 
scarcely one-half longer than the prothorax, scarcely as long as wide; 
under surface of the head polished, finely, sparsely punctured and 
convex, the gular sutures parallel and straight through the greater part 
of their extent and distinctly impressed. Male unknown. Length 4.0

Head perceptibly wider than the prothorax in both sexes, rather wider than

20— Smaller species, pale flavo-testaceous in color, more or less feebly 
clouded with piceous — notably on the posterior parts of the abdomen. 
Head only very slightly wider than the prothorax, finely, not densely 
punctate; prothorax rather large and well developed, notably wider 
than long and unusually strongly obtrapezoidal in form, the angles 
narrowly rounded; elytra rather small, quadrate, a fifth wider and 
about one-half longer than the prothorax; gular sutures straight. 
Median process of the fifth ventral short, about two-fifths as wide as 
the sinus, the latter relatively somewhat smaller and deeper than 
usual, the process very feebly, almost evenly sinuate at apex, its lateral 
angles narrowly rounded and with its sides parallel at base; fimbriate 
sides strongly curved and having unusually coarse black spinules; sur- 
face without the arcuate series of bristles before the process but 
clothed with very coarse black hairs throughout. Length 3.4 mm.; 
width 0.6 mm. California (Siskiyou Co.)..........pallescens n. sp.
