Type: Male, USNM 61825, from Cosincho region, Beni, Bolivia, 

 G. L. Harrington. 



Remarks: There is only a single specimen of this unusual little 

 species. The transverse elytral spotting and long legs are distinctive. 

 It is not very closely related to any other species. 



Disonycha multivittata, new species 



Figure 32 



About 8 mm. in length, oblong oval, rather flat, with wide explanate 

 margins, faintly shining, finely alutaceous and punctate; pale yellow 

 brown; antennae with the base of the first five or six joints pale, re- 

 mainder entirely dark; elytra with man}^ narrow pale vittae, including 

 a sutural, the usual median one broken up into three, and the sub- 

 marginal vitta broken up into two, none of these reaching the apex; 

 head, legs, and body beneath entirely pale. 



Head with interocular space about half width of head, entirely pale, 

 smooth over occiput, the usual fovea or cluster of punctures on each 

 side near the eye, tubercles marked b}^ a median depressed spot over 

 the narrow, slightly produced carina, lower front short. Antennae 

 short and moderately stout, the first two joints pale, joints 3 to 7 pale 

 in basal half, remainder entirely dark or with only extreme base pale. 

 Prothorax not quite twice as broad as long, with arcuate sides and 

 wide explanate margin, depressed over scutellum and on either side 

 near base; very indistinctly punctate, finely alutaceous, not very 

 shiny. Scutellum pale. Elytra finely alutaceous, not very shiny, 

 pale yellowish brown with vittae a little deeper brown, a narrow 

 sutural vitta, tln-ee very narrow median vittae, the submarginal- 

 lateral vitta broken up into two narrow ones, none of these reaching 

 the apex. Body beneath and legs enthely pale yellow brown. Length 

 7.5 to 8.3 mm., width 3.9 to 4.5 mm. 



Type: Male, and six para types, MCZ 29041, and one paratype, 

 USNM 61826, from Santa Catarina (3) and Rio de Janeiro (5), Brazil. 



Remarks: The general appearance of the elytral vittae is of many 

 pale vittae but possibh^ there are specimens that show onl}' a very 

 narrow sutural and median vitta, and these other vittae are merely 

 a subcutaneous darkening such as often is to be seen in the case of 

 punctures. 



Disonycha plagifera, new species 



Figure 43 



From 5 to 6.5 mm. in length, elongate oblong, finely alutaceous and 

 feebly shining, elytra finely punctate; head with a short dark oblong 

 spot on occiput; prothorax barely twice as wide as long and with a
