shining; pale yellow; deep brown antennae, brown apices to femora, 

 brown anterior tibiae, the posterior tibiae brown only at apex; elytra 

 with a narrow brown sutural vitta not reaching the apex, a short, 

 slightly sinuate, median vitta that is wider at the tip, a submarginal 

 vitta not nearly reaching the apex. 



Head with interocular space about half the width of the head, 

 smoothly rounded over occiput with a circle of punctures on each 

 side near the eye, frontal tubercles finely marked and carina between 

 antennal sockets narrowly produced, lower front narrow and rather 

 long, mouthparts deeper brown. Antennae long, with the three basal 

 and apical joint paler than the other joints, which are deep brown. 

 Pro thorax a httle more than twice as wide as long, not very convex, 

 somewhat depressed over scutellum, a wide explanate m_argin, entirely 

 pale yellow, shining, very indistinctly punctate. Elytra also flattish, 

 with a wide explanate margin, shining pale yellow, with a narrow 

 reddish bro\^^l sutural vitta not reaching the apex, a short sinuate 

 median vitta knobbed at its apex and extending only to apical curve, 

 a narrow submarginal vitta not nearly reaching the apex, epipleura 

 pale with a dark inner half below the humeri to the middle. Body 

 beneath pale, the femora pale with dark brown apices, anterior tibiae 

 brown, posterior tibiae with apices brown, tarsi dark. Length 6.6 

 mm.., width 3.4 mm. 



Type: Female, MCZ 29040 (Bowditch collection), Rio de Janeiro, 

 Brazil; paratype, female, USNM 61828, "St. Catharina, Brazil." 



Remarks: This species is distinctive because of its wide explanate 

 margin and unusually short elj^ral vittae, none of which reach the 

 apex. Unfortunately there is no male specimen.

Figure 51 

 Nephrica nigrofasciata Jacoby, Proc. Zool. Soc. London, p. 197, 1902. 



About 8 mm. in length, broadly oblong oval, elytra rather coarsely 

 punctate, shiny; head entirely dark, antennae dark with the four 

 distal joints pale; pro thorax pale; elytra with wide sutural, median, 

 and not so wide marginal vittae, the last joined at the apex with the 

 sutural vitta; body beneath with breast and abdomen dark, femora 

 and tibiae dark at apex, tarsi dark. 



Head with interocular space half width of head, e3'es no larger or 

 more deeply emarginate than in an}^ other species of Disonycha, 

 head shining black with a deep reddish brown spot below antennal 

 sockets, a cluster of coarse punctures on each side near eye extending 

 down towards frontal tubercles, tubercles well marked, carina nar- 

 rowly produced, lower front moderately long. Antennae long, the 

 three basal joints pale edged, the distal four joints entirely pale,
