which are rather small but prominent ; frontal impression distinct and 

 "with a few coarser punctules in a double series ; frontal margin transversely 

 truncate at apex, the tooth strong and narrow ; occiput vertical at base, An- 

 tennse slender and elongate, rather more than 14 as long as the body, incrassate 

 toward tip ; first three joints decreasing gradually and slightly in thickness, 

 feebly obconic, the first twice as long as wide ; second % longer than wide ; 

 three to seven subequal in thickness and subcylindric; third and fifth %, fourth 

 and sixth }4, and seventh '%, longer than wide ; eighth, elongate-oval, nar- 

 rowed toward base, % longer than wide, distinctly longer than the seventh or 

 ninth ; three outer joints increasing but little in thickness, the ninth a little 

 longer than wide ; tenth subquadrate ; eleventh gradually pointed, much 

 shorter than the two preceding. Prolhorax rather longer than wide, conic, the 

 sides but slightly arcuate ; apex not tubulate, feebly arcuate and ^2. ^s wide 

 as the base, the latter feebly arcuate and not % wider than the head; disk per- 

 fectly even and without trace of impression. Elytra fully }4, longer than 

 wide, more than twice as long as the prothorax and % wider, widest before 

 the middle ; sides evenly arcuate from base to apex, the latter narrowly 

 rounded ; two basal fovese on each rather approximate ; subhumeral impres- 

 sion moderate, the humeral plica wide and distinct but not much elongated 

 disk distinctly impressed at the suture near the base, the suture strongly 

 beaded toward base. Abdomen coarsely flavo-pubescent. Legs rather long, 

 the femora all strongly clavate. Length 2.2 mm. ; width 0.85 mm. 



Florida (St. Johns River). 



The sex of the single specimen before me is undoubtedly male, 

 as shown by antenual structure and the conformation of the 

 apical plates of the abdomen. Sexual differences in form are 

 probably very slight. The species may be readily known by its 

 large size and impressed elytra, with the suture strongly beaded. 



3. C longipenne n. sp. — Elongate and moderately slender, polished and 

 impunctate, piceous-black, the elytra throughout very dark ruf o-piceous ; under 

 surface blackish, the abdomen pale at tip; legs and antennse dark rufous, the 

 femora still darker; pubescence long and abundant, flavescent on the elytra. 

 Head slightly wider than long, almost semicircularly rounded behind the eyes, 

 the latter rather small and moderately convex ; neck narrow, barely % of the 

 maximum width; clypeal tooth strong and rather pointed; occiput deeply ver- 

 tical at base. Antennas }4 as long as the body, slender, the club feebly differ- 

 entiated; first three joints decreasing uniformly and gradually in thickness, 

 the first and second nearly twice as long as wide, the latter shorter than the 

 next two; three to six equal in width, cylindric; third and sixth %, fourth %, 

 fifth }4, longer than wide; seventh slightly thicker, 3^ longer than wide, as 

 long as the eighth, the latter feebly obconic, % longer than wide, rather longer 

 than the ninth, which is but slightly longer than wide; outer joints increasing 

 feebly in thickness. Prothorax a little longer than wide, conic, the sides very 

 feebly and almost evenly arcuate ; apex truncate, not at all tubulate, }4 as 

 wide as the base, the latter feebly arcuate and scarcely )^ wider than the bead;
