332 COLEOPTERA. 



large deep fovea each side of the middle and an additional small one 

 between it and the lateral anterior edge, scutel flavous, elytra very 

 finely punctulate striate, dull flavous, the suture and alternating inter- 

 spaces including the margin narrowly black vittate, below with legs, 

 aeneous, blackish, rufescent. Length 7^ mm. 



One example, St. Catharina, Brazil (ex Klages). 



Allied in marking to polychordia Er. The thorax is notice- 

 ably much thickened on the sides, which are straight behind ; 

 much rounded, in fact, almost angulate in front, and with 

 the anterior angles short and pointed. The elytra striae are 

 very fine, in longitudinal depressions so that the intervals 

 appear raised, giving the elytra a sulcate appearance, the 

 sutural vitta vanishes at about the apical third, the subsutural 

 and marginal almost attain the apex, the second and fourth 

 (counting on the disk) are a little shorter and the third ends 

 at the apical third — easily separated by the sulcate appear- 

 ing elytra and foveate thorax — the second flavous interspace 

 is noticeably swollen and protuberant at the base, and all the 

 spaces both yellow and black appear as if ridged in middle. 



Desiiiogramma brunneo-niaciilata nov. sp. 



Head, thorax, antennae, legs and underside dark brownish-black, 

 the antennffi and mouth parts somewhat rufous, head and thorax spar- 

 ingly punctate, the latter a trifle more so at the sides, scutel brown- 

 black, elytra dark orange fulvous red, with a common sutural vitta 

 covering the second interspace, and the lateral margin dark brown, 

 also on each elytra at anterior third two small indefinite brown dashes 

 on the fourth and sixth intervals, also behind the middle on the same 

 intervals two other dashes of similar color, the outer much longer and 

 stronger. Length 8 mm. 



One example, Venezuela. 



The sides of the thorax are almost uniformly rounded and 

 the anterior angles short and pointed. The stria of the 

 elytra are fine and regular, except 5-6 is broken in the mid- 

 dle with closed ends ; the apex is practically fulvous, the 

 extension of the black vitta showing only a faint blackish 

 streak, the lateral brown vitta extends only to the tenth stria 

 of punctures. 



DesinogTainnia ignotus nov. sp.
