ART. 23 REVISION OF THE BEETLE GENUS OEDIONYCHIS — BLAKE 37 



expanding at middle and apex as if joined with spot, two lateral 

 and three median s})ots on each elytron, the first median near base 

 of vitta. the second median opposite middle expansion of vitta, and 

 third median at apical expansion, the two lateral not opposite but 

 placed between these median spots. Body beneath yellow, finely 

 pubescent, abdomen and nieso- and metasterna slightly darker. 



Length. — 4.5 mm. ; width 2 mm. 



Type ami paratype.—C^t. No. 29158, U.S.N.M. One paratype in 

 British Museum. 



Type locality. — Crescent City, Fla. 



This species is based on two specimens, one collected at Crescent 

 City, Fla. (Hubbard and Schwarz), the other merely labeled Fla. 

 Coll. C. V. Riley, probably from the same source. It differs from 

 scaJaris in having smaller eyes and narrower elytra, and in having 

 an additional spot on margin of elytra. It differs from nigrosigriata 

 in having coarser punctation and dark basal margin and sutural 

 vitta and smaller number of spots. The humeral prominences are 

 slightly more marked. There is one specimen of the same species 

 in the British Museum without locality label.

 Avith sides nearly parallel, with broad, explanate margin; umbone 

 prominences well defined with deep depression within; punctation
