tibiae, and dark tarsi; elytra with a very narrow dark median and 

 sutural vitta; body beneath pale. 



Head usually entirely pale, smooth, shinmg, a fovea near eye, frontal 

 tubercles rather faintly m.arked, carina narrowly produced, lower front 

 not long, interocular space more than half the width of the head. 

 Antennae with the basal joints pale, apical one sometimes paler than 

 the dark ones preceding it. Pro thorax about twice as wide as long, 

 with arcuate sides, rather depressed over the scutellum, smooth and 

 impunctate, faintly alutaceous, entirely pale. Scutellum pale. 

 Elytra pale, with a very narrow dark sutural and median vitta, finely 

 a,lutaceous and very indistinctly punctate. Body beneath entirely 

 pale, femora pale, the tibiae with a dark outer streak, tarsi deep brown 

 or piceous. Length 6 to 8.8 mm., width 3 to 4.2 mm.

Remarks: This is another of the group to which D. abbreviata 

 Melsheimer and D. leiHolineata Blatchley belong. Unlike the others, 

 except the Florida form of D. leptolineala, this has very narrow elytral 

 vittae. Unlike D. leptolineata var. texana Schaeffer, the breast is not 

 dark. Jacoby gives Mexico, Guatemala, and Panama as localities for 

 this species. Representing his material in the Bowditch collection is 

 a specimen from David, Chiriqui, Panamd, collected by Champion, 

 that is without a submarginal elytral vitta. There are also three 

 others in the Bowditch collection from Guatemala, one a female with 

 a submarginal vitta and a difi'erentlj^ shaped scutellum and prothorax, 

 and another a female from Comitdn with a similar submarginal stripe. 

 Both of them are slightly larger and paler and I believe they are 

 Disonycha (Cacoscelis) quinquelineata (Latreille).
