42 PROCEEDINGS OF THE NATIONAL MUSEUM vol. io4 



Type: Not designated; cotypes, in BM, MCZ (Bowditcli collection, 

 7), and USNM (1), from Volcd^n de Chiriqui, Panam^, 2-3,000 ft., 

 Champion. 



Other localities: Costa Rica: San Pedro de Montes de Oca, 

 C. H. Ballou. Panamd: Porto Bello, on Polygonum, E. A. Schwarz 

 and August Busck; La Chorrera; El Valle del Ant6n, G. C. Wood; 

 Ciricito, Canal Zone. Colombia: Colegio, E. A. Chapin. 



Remarks: The wide explanate margin and usually Y-shaped pro- 

 notal marldng distinguish this species. The type specimens have deep 

 reddish brown marldng, but other specimens both from the Canal Zone 

 and Colombia have the usual piceous vittae. 



Disonycha longipennis, new species 



Figure 38 



About 7 mm. in length, elongate oblong oval, shining, mirror 

 smooth; pale yellow; a dark band across occiput, dark tubercles, and 

 brownish mouthparts; pro thorax 5-spotted; scutellum dark; elytra 

 with sutural edges and margin narrowly dark, wider at apex, a spot 

 at middle of base representing median vitta; body beneath with 

 breast and legs dark. 



Head with interocular space less than half the width of head, eyes 

 large, not at all reniform, a dark band across occiput l^ehind the 

 eyes and a brownish spot over tubercles, a fovea on either side of 

 front near eye and a few punctures on front, tubercles well defined, 

 carina short and narrow, lower front not long, mouthparts brownish. 

 Antennae not unusually long, dark except the paler edging of the tliree 

 basal joints and the three apical joints lighter brownish. Prothorax 

 twice as wide as long, with wide anterior angles and slightly curved 

 sides, disc rather flat and depressed over scutellum, surface shining, 

 very faintly punctate, pale yellow with five small brownish spots. 

 Scutellum dark. Elytra elongate, not very convex, pale yellow with 

 the sutural edges darkened and the margin narrowly dark, more 

 broadly so at the apex, a spot in the middle of the basal margin 

 representing a trace of the median vitta, epipleura dark. Body 

 beneath pale, with the breast and legs dark. Length 7.2 mm., width 

 3 mm. 



Type: Female, USNM 61816, from Summit, Canal Zone, Panamd, 

 collected by N. L. H. Krauss in September 1946. 



Remarks: Although this may be a pale form of a species having an 

 entire dark median elytral vitta, it does not agree with any kno^^m 

 species with the usual vittation. The elytra are very elongate, 

 without any costation. In the Bowditch collection are two specimens 

 that bear a certain resemblance to this in their elongate shape, although
