of the shoulders but little greater than that of the thorax, 
three-fourths as wide as across the tip, discal lines quadrifove- 
ate; intermediate fovez two, lateral declivity slightly concave. 
Abdomen with a pubescent transverse line on the basal seg- 
ment. Legs short and slender.

F. corticinus, Casey. More elongate than the preceding, 
pale brown, pubescence shorter, finer, surface impunctate. 
Length 1.5 mm. Plate XII., Fig. 127. 
flead 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 slightly convex, less than two-thirds 
the distance across the tempora, front deeply excavated; ver- 
tex with two smail punctiform fovez, mutually less distant 
than either from the eye. Antenne 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. Pvrothorax 
widest in the middle, evenly rounded, very slightly sinuate 
toward the base; discal fovez 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 carine; 
lateral foveze large, extending to the lateral basal angle. 
£lytra 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 lines with two large punctures 
near the base, intermediate punctures three in the longitudinal 
row. Aéddomen slightly longer and wider than the elytra, 
marginal border one-seventh of the segmental width; the basal
