26 Mr. Joseph S. Baly on the 



Head not longer than broad ; clypeal ridge prominent, entire ; 

 antennae nearly equal to the body in length, filiforixi, the second 

 and third joints short, eqnal, the fourth much longer than the pre- 

 ceding two united ; fiiscous, the thi'ee lower joints, together with 

 the ninth and tenth, tiavous. Thorax nearly one-half broader than 

 long.; sides slightly produced and rounded anteriorly, nearly 

 straight and parallel behind the middle ; disk convex, not foveo- 

 late. Elytra oblong-ovate, convex, closely punctured ; flavous, each 

 elytron with a narrow sutural line, dilated at the base and extending 

 downwards slightly below the middle, a subtriangular basal patch 

 covering the humeral callus, a subrotundate spot on the outer disk 

 at its middle and two smaller spots placed transversely on the 

 hinder disk, half-way between the middle and apex, black ; the basal 

 margin between the humeral patch and the suture also narrowly 

 edged with black ; the lower and inner angle of the basal patch is 

 joined to the suture by a narrow piceous line. 



The specimen of this species, kindly lent me hy Mr. 

 Jacoby, and from which the above description was 

 drawn, differs slightly in the coloration of its antennse 

 and legs from the diagnosis given in that author's paper ; 

 it is however, probably somewhat variable in colom*.

Hah. Ecuador {Buckleij). A single specimen in Mr. 

 Fry's collection. 



Head not longer than broad, entirely black ; antennae filiform, 

 equal to the body in length, the second joint short, the third half 

 as long again as the second, the fourth longer than the preceding 

 two united. Thorax nearly one-half broader than long ; sides 

 faintly sinuate from the base to just beyond the middle, thence 

 rounded and converging towards the apex ; disk convex, nitidous, 

 impressed on either side with a small shallow fovea. Elytra 

 broadly ovate, dilated posteriorly, conxex, distinctly and rather 

 closely punctured ; flavous, some irregular patches on the middle 

 disk, confluent with each other and also with the sutural and 

 humeral vittse, black ; the apical third of the disk immaculate.
