16 THE CANADIAN ENTOMOLOGIST. 



coarsely punctate, deeply trifoveate; scutel piceoiis rufous; elytra thickly 

 punctate, shining black, the margins, the suture (very narrowly behind) 

 and a median band dilated at the sides and suture, flavous; beneath, thorax 

 red, body black, legs flavous with tibiae and tarsi and apex of femora 

 above, and coxae black. Length, 6 ram. 



Type t example, Puerto Bertoni Alto Parana, Paraguay, sent me by 

 Mr. Schrotky, also a specimen in the Jacoby collection labelled "i A.A. 

 28 In Ocynis." 



Should be placed near borrei Baly, but the punctuation and flavous 

 maikings very different ; the thorax is much broader than long, slightly 

 sinuate behind, the fovea connected by a well marked sulcus; the punc- 

 tuation of the elytra is rather coarse and thick, becoming obsolete behind; 

 the black spots do not attain the basal margin (as in borrei) and there is 

 a well marked sulcus on the suturai side of the shoulder; and the elytra 

 are very obsoletely shortly plicate ; the suturai yellow stripe is narrowed 

 behind to a mere line just separating the black spots on the elytra ; all 

 the spots have the angles rounded. 



D. thajumii, no v. s p. 



Head and thorax rufous ; antennae fuscous, tip of last joint dark. 

 Thorax wider than long, trifoveate, the lateral ones oblique and deep ; 

 scutel rufous or piceous ; elytra thickly punctate, dull shiny black, the 

 lateral margin slightly dilated at the apex and a median transverse fascia 

 more or less dilated up and down the suture, flivous. Beneath, thorax red, 

 body black, legs yellow, tarsi more or less piceous. Length, 5-5^/^ mm. 



Type, Marcapata, Peru, in 2nd Jacoby collection; also Pachitea, Peru ; 

 single example in the ist Jacoby collection, Chanchomayo, Peru (Thamm) 

 labelled '^concula Er. Ç ?" Twelve examples in all. 



Very like bertonii supra and near borrei Baly. The antennae $ 

 are ^ as long as body, joint 3 and 4 nearly equal; the thorax is broadly 

 margined and slightly sinuate behind and the surface is sparsely evidently 

 punctate. The black of the elytra varies considerably; in what I consider 

 typical there is a solid basilar fascia ; but specimens occur where 

 the fascia is divided into two distinct rounded subbasal spots, leaving a 

 wide suturai yellow stripe and a narrow basilar stripe, flavous, all the 

 flavous marks connected. In this form also the rear fascia is narrowly 

 subdivided by the narrow yellow suture. The elytra are shortly obsoletely 

 plicate.
