of the shoulders but little greater than that of the thorax, 

 three-fourths as wide as across the tip, discal lines quadrifove- 

 ate; intermediate foveae two, lateral declivity slightly concave. 

 Abdomen with a pubescent transverse line on the basal seg- 

 ment. L<egs short and slender. 

 Habitat. Middle Calfornia. 



F. corticinus, Casey. More elongate than the preceding, 

 pale brown, pubescence shorter, finer, surface impunctate. 

 Length 1.5 mm. Plate XII., Fig. 127. 



Head wider than long, four-fifths as wide as the prothorax, 

 trapeziform, eyes small, situated in the middle of the straight, 

 anteriorly convergent, sides; tempora rather prominent, 

 rounded, frontal margin shghtly convex, less than two-thirds 

 the distance across the tempora, front deeply excavated; ver- 

 tex with two small punctiform foveas, mutually less distant 

 than either from the eye. AnteuHce one-third longer than the 

 head and prothorax together, first joint longer and little 

 thicker than the second; the second is nearly one-half longer 

 than wide, oval; third to ninth smaller, moniliform, gradually 

 shorter, and wider than long; tenth and eleventh slightly 

 larger, the former transverse, the latter wider, and a little 

 longer than wide, as long as the two preceding together. 

 The fourth joint of the maxillary palpi is longer than wide, 

 compressed oval, with a terminal pencil of hair. Prothorax 

 widest in the middle, evenly rounded, very slightly sinuate 

 toward the base; discal foveae just before the middle, mutually 

 distant one-fifth of the pronotal width; basal excavation foveate 

 in the middle, and limited on the angle by the lateral carin£e; 

 lateral fovese large, extending to the lateral basal angle. 

 Elytra a little wider across the shoulders than the prothorax, 

 across the tip less than one-fourth wider, the width here being 

 equal to the sutural length; disk depressed, the sutural lines 

 punctate at the base, the discal Hues with two large punctures 

 near the base, intermediate punctures three in the longitudinal 

 row. Abdomen slightly longer and wider than the elytra, 

 marginal border one-seventh of the segmental width; the basal
