features which consist in the elytral interstices being of elongate 

 not broad shape, in connection with the spots and the sculpture 

 of the thorax ; there is however to be noticed in regard to the 

 sculpturing, that the elytra have a small roundish raised spot 

 (conspicuous amongst the interstices) placed close to the suture 

 below the middle , and that the spots are almost invisible in 

 some instances, while in others they are very plainly marked. 



3. Urodera interstitialis, sp. n. — Black, head and thorax very 

 finely and closely punctured, basal lobe of the latter truncate, 

 elytra finely punctate-striate, the interstices likewise very finely 

 but distinctly punctured, an angular transverse band at the base 

 and a transverse spot at the apex, fulvous. 



Length 6-7 mill. 



Of subquadrate shape, the head strongly defiexed, finely and 

 closely punctured, antennae black, the second and third joints 

 fulvous, thorax very broad at the middle, the sides nearly 

 straight, scarcely narrowed anteriorly, with a narrow flattened 

 margin , which is finely rugose and punctured , the rest of the 

 disc, finely and very closely punctured, the median lobe strongly 

 produced and truncate, obliquely depressed at each side, scutel- 

 lum with a few minute punctures, elytra with a shallow trans- 

 verse depression below the shoulders, black, and like the thorax, 

 with a slightly aeneous or cupreous lustre, finely punctate-striate, 

 the interstices also very finely punctured, the base with a trans- 

 verse fulvous angular band, surrounding the shoulders and not 

 extending to the suture but laterally nearly to the middle of the 

 civ tra, the apex with another transversely shaped fulvous spot. 



Of this species, distinct from any of its congeners by the fine 

 but well marked punctuation of the elytral interstices. 1 possess 

 three specimens all from Paraguay, but if they all represent 

 the same species I am somewhat doubtfull; in one of them the 

 head is very elongate, with a central fovea, in this specimen 

 the punctuation of this part, the thorax and the elytral inter- 

 stices is very distinct and the upper surface has a slight metallic 

 tint, in the other two, probably males, the punctuation is very 

 fine and less marked although well visible with a lens, the an-
