586 Coleopterological Notices, V. 



Aiitemise in the female one-lialf as long as the hody ; flanks of the prothorax 

 simply punctate heneath, the prosternum much less coarsely punctate. 

 Black, the elytra and abdomen red, polished. Head coarsely, strongly 

 punctate, feebly impressed along the middle. Prothorax one-half longer 

 than wide, the sides broadly arcuate, more convergent and feebly constricted 

 near the base, the latter equal in width to the apex, both truncate ; disk 

 coarsely, deeply punctate, the punctures forming transverse rugse which are 

 obsolete along the median line and gradually evanescent beneath. Scutellum 

 small, impunctate, the horizontal posterior part not carinate and not longer 

 than wide. Elytra parallel, not quite twice as long as the prothorax, nearly 

 two and one-half times as long as wide, narrowly truncate at apex, impressed 

 and punctate nearly as in bicolor, but rather less densely. Length 8.5 mm. ; 

 width 2.0 mm. Florida "brevicornis n. sp. 



In bicolor the transverse area behind the buccal opening is more 

 finely sculptured than in brevicornis, and the transverse prosternal 

 constriction is very much deeper ; brevicornis is slightly the smaller 

 of the two. 



TRAGIDIOIV Serv. 



The species of this genus may be know^n by the following charac- 

 ters : — 



Third joint of the hind tarsi not longer, and but seldom visibly wider than, 



the second ; elytra corrugated. 



Antennse more or less pale, the swollen apices of the pale joints black and 



abruptly more densely pubescent. 



Antennae entirely black toward apex ; elytra strongly narrowed from base 



to apex ; large species, the black hairs of the pronotum and legs with 



a strong cobalt-blue reflection annillatlllll 



Antennje pale throughout, the apices of all the joints black ; elytra 

 parallel ; size smaller, black ; the hairs without blue reflection ; hind 



tibiae moderately dilated and compressed ....auripenne 



Antennae black throughout ; apices of the joints feebly swollen but not 



more densely pubescent. 



Third joint of the hind tarsi scarcely shorter than the second ; posterior 



tibise not distinctly modified ; elytra varying from black with a small 



fulvous spot behind the humeri to completely fulvous except at the 



basal margin coquus 



Third joint small, very much shorter than the second ; posterior tibiae 

 broader, strongly compressed ; elytra fulvous throughout except at 



base fulvipeime 



Third joint of the hind tarsi distinctly longer and somewhat wider than the 

 second ; elytra not corrugated, parallel, each with three feeble and minutely 

 costuliform lines ; pronotal punctures in the male minute and dense but 

 becoming abruptly coarse in an apical band, the posterior transverse margin 

 of which is multisinuate ; in the female minute and dense throughout.
