F. laticollis n. sp. — Rather robust; body very dark piceous; pronotum 

 and three basal joints of the abdomen paler, dark brown; legs translucent, 

 testaceous; antennae fuscous; integumeuts polished; pubescence line and not 

 very dense, cinereous. Head rather large, wider than long; sides behind 

 the eyes short and parallel, arcuate; base broadly truncate; basal angles 

 broadly rounded; occiput rather convex; front very wide, flat; punctures 

 rather coarse, feeble and sparse; antennae much longer than the head and 

 prothorax together, very slender, three basal j jints elongate, sub-equa 1 in 

 length, fourth slightly longer than the succeeding joints, twice as long as 

 wide, tenth very slightly wider than long, eleventh slender, obliquely and 

 gradually acuminate, slightly longer than the two preceding together. Pro- 

 thorax widest at a little over one-third its length from the apex where it is as 

 wide as the head and one-sixth wider than long; sides convergent and slightly 

 arcuate to the apex which is squarely truncate, and very slightly less strongly 

 convergent and feebly sinuate to the base which is broadly and evenly arcuate, 

 four-fifths as wide as the disk and very slightly wider than the apex; basal 

 angles obtuse and distinctly rounded; disk declivous and convex along the 

 sides, broadly and very feebly impressed in the middle from the anterior third 

 nearly to the basal margin where there are two approximate and feeble, eroded 

 impressions which are sometimes sub-confluent; extremely minutely, feebly 

 and very sparsely punctate. Elytra at base one-third wider than the pro- 

 thorax; sides very feebly divergent and feebly arcuate, more strongly so 

 toward the apical angles which are scarcely produced; together broadly 

 truncate behind and feebly sinuate toward the suture; disk very slightly 

 wider than long and about one-third longer than the pronotum, feebly convex, 

 distinctly impressed on the suture toward the base, extremely miuutely, 

 evenly and rather sparsely punctate. Abdomen at base much wider than the 

 pronotum and very slightly narrower than the elytra; sides nearly parallel 

 and very feebly arcuate; basal impressions deep and almost entirely impunc- 

 tate, strongly shining, elsevhere very minutely and moderately densely 

 punctate; border strong, inclined. Legs very slender; posterior tarsi mod- 

 erately long, first joint but slightly longer than the next two together and 

 nearly as long as the last three. Length 2.7 mm. 



California (Gilroy Springs, Sta. Clara Co. 3). 



The type specimen is a male, the sixth ventral segment 

 being truncate at apex; in the female, which is slightly more 

 robust, this segment is broadly and rather strongly sinuate 

 at tip. The species is very distinct by reason of the pronotal 

 structure, this not being canaliculate and having two small 

 punctures near the base ; it is also more strongly transverse
