AET. 28 EEVISION OP DISONYCHA NORTH OF MEXICO BLAKE 15 



reddish sutiiral, median, and submarginal vittae, these vittae so wide 

 as to leave onl}^ narrow intervening vittae, the submarginal and 

 sutural usually uniting at apex. Body beneath finely pubescent, pale 

 with mesosternum and metasternum and often middle of abdomen 

 dark ; tibiae and tarsi also dark. Length, 4.4 to 5,5 mm ; width, 2.2 to 

 3 mm. 



Type locality. — " Carolina " (Bosc collection). 



Distribution. — North Carolina, Georgia, Florida (Bradenton, 

 Capron, Enterprise, Fort Myers, Jacksonville, Lake Harney, Lake- 

 land, Lee Count}', Lake Poinsett, Miami, Moore Haven, Orlando, 

 Paradise Key, Sanford) ; Cuba (Habana). 



Food ylant. — Polygonum sp. (H. S. Barber). 



Remarks. — D. conjugata, one of the earliest species of Disonycha 

 to be described, has been published under a number of names. Fabri- 

 cius described it from a collection by Bosc from " Carolina " as 

 conjugata. Old specimens in the LeConte collection and elsewhere 

 are labeled with a Dejean Catalogue name signifying its reddish 

 color. Jacquelin du Val described it from Cuba as Monomacra 

 costipennis. Jacoby later described it from Florida as floridana, 

 and it has been treated as a variety of pensylvanica by Horn. Its 

 yellowish or pale reddish elytra readily distinguisli it from any other 

 species of Disonycha. It is closely related to D. pensylvanica,
