the much stronger punctuation of the elytra, wliich is plainly visible 

 with the naked eye. 



DORYPHORA PICTIPENNIS, Sp. nOV. 



Black. Tliorax with stronply rounded sides, the latter closely 

 punctured ; elytra testaceous, irregulaily and closely covered with 

 numerous small black sjiots. 



Length 8| lines. 



Head extremely finely punctured, the lower edge of the epistome 

 and the anterior margin of the labrum sometimes testaceous; 

 antennpe scarcely extending beyond the base of the thorax, black, 

 the ajnces of the first two joints sometimes testaceous, the third 

 joint very long and slender, the five lower joints shining, the rest 

 opaque, pubescerit, and longer than broad. Thorax very transverse, 

 about three times as broad as long, the sides strongly rounded, tlie 

 angles acutely produced, the anterior ones toothed ; surface deeply 

 and rather closely punctured at the sides, the middle of the disk 

 nearly impunctate. Scutellum triangular; the apex acute, impunc- 

 tate. Elvtra covered with very numerous small punctures, each of 

 which is surrounded by a black ring; at the basal margin there are 

 some larger greenish aeneous spots ; the extreme lateral and sutural 

 margin is also hlack, as well as the elytral epipleurse ; mesosternal 

 process stout and straight. 



Hub. Amazons, St. Paulo d'Olivenga. (Coll. Oberthiir and my 

 own.) 



This species will find its place near D. glomerala, Stiil, D.pluviata, 

 Baly, and several others somewhat similarly marked ; the absence of 

 any transverse or lungitudinal elytral bands will distinguish it. 



Detjterocampta DiscicoLLis, sp. nov. 



Flavous or fulvous ; the sides of the hreast, the disk of the thorax, 

 and two transverse bands of the elytra, as well as a large triangular 

 spot at the apices of the latter, black. 



Length 3-3| hues. 



Head with a few fine punctures and a distinct longitudinal central 

 groove ; antennse short, entirely fulvous, the terminal joints slightly 

 thickened. Thorax more than three times as hroad as long, the 

 sides straight at the base, rounded towards the apex ; surface very 

 finely and rather remotely punctured, the n.iddle of the disk black, 

 the sides fulvous. Scutellum fulvous. Elytra regularly and finely 

 punctate-striate, the punctures distinct to the apex, fulvous ; a 

 narrow transverse band at the base extending to either margin, a 

 much broader band at the middle, abbreviated at either margin, and 

 a broad triangular spot near the apex of each elytron, black ; elytral 

 epipleurse, the underside (with the exception of the sides of the 

 breast) and the legs fulvous. 



Hab. Amazons, St. Paulo d'01iven§a. (ColL Oberthiir and my 

 own ) 



The elytra, if the black colour is taken for that of the ground, 

 have the margins and two narrow transverse bands (one before, the 

 other below, the middle) fulvous.
