CUCUJID/E 115 



not longer than wide. Body smaller and narrower than in rufiis, 

 evenly red-brown and shining throughout; head including mandibles 

 much longer than wide and distinctly narrower than the prothorax, 

 the median sulcus stronger than in any of the others and the punctu- 

 ation more minute, abruptly coarse basally as usual, the oblique 

 impressions very coarse; antennae barely equal in length to the head 

 and prothorax, the latter as in rufus throughout, except that the 

 sides do not become parallel at base as they do in that species; 

 scutellum transversely rounded; elytra two and one-half times as 

 long as the prothorax and slightly wider, with the usual outline, 

 having four deep entire sulciform and impunctate grooves, the fifth 

 sulciform and impunctate to well behind the middle, where it be- 

 comes a feebly impressed series of close-set punctures, the sixth a 

 series of close-set punctures becoming subsulciform basally, the fifth 

 and sixth much more approximate than the others, the seventh 

 acutely cariniform as usual; deep transverse subangulate groove of 

 the last ventral at some distance from the hind margin. Length 

 (9 ) 8.0 mm.; width 1.8 mm. Florida (Lake Worth), Kinzel. 



monilicornis n. sp. 



Antennae much longer than the head and prothorax in both sexes; 

 longitudinal sulcus of the head entire but very feebly impressed 

 throughout 3 



3 Form rather depressed, the lustre shining; color dark castaneous, the 

 femora rufous; head broader than in the preceding though evidently 

 narrower than the prothorax, more coarsely but loosely punctate, 

 the antennae very much longer though notably thick, as long as the 

 elytra (cf ) or three-fourths as long as the latter and not quite so 

 thick (9), the joints much elongated, the eleventh only slightly 

 longer but narrower than the tenth, with its apex obliquely pointed, 

 the erect pale hairs, internally, long and dense, shorter and fewer in 

 the female; second joint not as long as wide; eyes well developed and 

 convex; prothorax slightly longer than wide, the sides feebly con- 

 verging and straight from the apex to basal two-fifths, there becom- 

 ing oblique and arcuate, then parallel and straight for some distance 

 before the basal angles, which are right, the parallel part paralleled 

 by a distinct carina; punctures moderately strong, deep, not close, 

 coarser on the flattened median area and wanting in a narrow im- 

 punctate line; scutellum slightly transverse, rounded; elytra two 

 and three-fourths times as long as the prothorax and much wider, 

 of the usual outline; sculpture as in the preceding, except that the 

 punctures on the flat subvertical flanks are coarser and much closer; 

 transverse groove of the last ventral not quite so remote from the 

 hind margin, the intervening space finely and rather closely punctate. 

 Length (5 cf, 2 9) 9.7-11.8 mm.; width 2.2-2.7 mm - Iowa, 

 Maryland and Florida. [Cucujus rufus Fabr.] rufus Fabr. 



Form nearly as in rufus but narrower and with distinctly more slender 

 antennae, red-brown in color and shining; head distinctly narrower 

 and rather more finely and closely punctate; antennae (9 ) about as 

 long as in the female of rufus but less stout, the joints elongate, the 

 eleventh longer but not evidently narrower than the tenth and more
