176 GEO. H. HORN, M. D. 



coarsely tridentate, crest narrow and long, reaching nearly the tip of the horn, 

 feebly elevated, distinctly margined, slightly serrulate; elytra oval, humeri dis- 

 tinct, apices conjointly rounded, disc coarsely, deeply and moderately densely 

 punctured, densely clothed with silvery white scales, with brown scales forming a 

 design as follows : a fascia exactly median, the suture from the fascia to the scutel- 

 lum, an oblique fascia on each side between the middle and apex ; body beneath 

 finely punctured and clothed with fine silvery white pubescence. Length .06— .08 

 inch ; 1.6 mm. 



The male has the last ventral segment slightly emarginate at tip. 



This species is remarkably constant in the form of the thoracic horn 

 and the markings on the elytra, the only variation observed is in the 

 partial obliteration of the oblique fascia. 



Collected at Capron, Florida, not rare.
