ately dense, recumbent, more dense on the abdomen toward tip; integu- 

 ments polished. Head moderate, as wide as long, truncate at base; sides 

 parallel for a short distance behind the eyes; basal angles broadly rounded ; 

 base and occiput strongly convex, front nearly flat; punctures very minute, 

 feeble and rather sparse; antennae distinctly longer than the head and pro - 

 thorax together, moderately slender and feebly incrassate, first three joints 

 sub-equal in length, the first slightly more robust, the third conical and 

 more than twice as long as wide, joints four to ten, equal in length, the 

 former distinctly longer than wide, the latter slightly wider than long, 

 eleventh ovoidal, acuminate, slightly thicker than the tenth and as long as 

 the two preceding together. Prothorax widest at one-third its length from 

 the apex, where it is very slightly narrower than long and scarcely as wide 

 as the head; sides strongly convergent antt-i-iorly and strongly arcuate, 

 much less strongly convergent posteriorly and just visibly sinuate; base 

 broa Uy, evenly and rather feebly arcuate, three-fourths as wide as the disk 

 and nearly twice as wide as the apex; basal angles narrowly rounded; disk 

 broadly and strongly declivous and convex along the sides, narrowly de- 

 clivous along the base, feebly canaliculate along the middle, the furrow being 

 narrowly impressed and vanishing toward the apex, not attaining the base; 

 punctuation fine, even and rather sparse. Elytra at base one-third wider 

 than the pronotum; sides parallel and feebly arcuate, more strongly so toward 

 tip; together truncate behind; apical angles very small and slightly pro- 

 duced; disk nearly quadrate, distinctly longer than the prothorax, mod- 

 erately convex, extremely, finely and rather sparsely punctate; punctures not 

 appreciably denser toward the scutellum which is more densely asperate but 

 not channeled. Abdomen at base much wider than the pronotum and slightly 

 narrower than the elytr.i; sides feebly convergent to the apex of the sixth 

 segment and rather strongly arcuate; border strong; three basal segments 

 transversely and deeply impressed, channels very narrow, sparsely and rather 

 more coarsely punctate, remainder finely and rather densely punctate. 

 Legs long and very slender; posterior tarsi long, first joint distinctly longer 

 than the next three together, second slightly shorter than the fifth. Length. 

 2.2-2.7 mm.

This species may be distinguislied by the feebly canalicu- 

 late pronotum, its slender form, sparse punctuation and 

 form of the prothorax.. F. cavipenriis, Lee. having a feebly 

 sub-sulcate pronotum, has been described from California, 

 but its roughly granulose elytra and habitat, being found 

 on the sea shore, point it out as being aberrant and prob- 

 ably belonging to another genus; I have not, however, been
