humerus to about the end of the median third, black below and legs 

 yellow, pectus black. Length, 5 mm. 



Two examples, Caparo Valley, Pt. of Spain, 1-97, Dr. Rendall. One 

 example, Trinidad. 



Comes near cavicollis Baly. The piceous colour of the antenna? 

 stops abiuptly at the end of the eighth joint, the thorax is broader than 

 long, with moderately sinuate sides, impunctate ; elytra are dilated as in 

 cavicollis Baly, and the colour and markings are just as in that species, but 

 the antennae and thorax are very different, and at once separate the two. 



D. i>oggiaJii, nov. sp. 



Head yellow, antennae about one-half the length of the body, black, 

 with the first three and last three joints pale ; thorax yellow, shining, 

 impunctate ; scutel yellow, elytra pallid whitish-yellow, a common sutural 

 line reaching the middle, a humeral sublateral stripe extending nearly to 

 the apex, a discoidal stripe, abbreviated anteriorly just before ihe middle 

 and posteriorly at the convexity, black, below and legs yellow, pectus 

 black. Length, 5 mm. 



One example, Pt.° 14, de Mayo G. Boggiani, 1-1897 (Mus. Genova.). 



Near kirbyi Baly. The antennae are stout, the fourth joint barely as 

 long as the two preceding ; the thorax is broader than long and only 

 moderately sinuate behind ; the elytra are not plicate, and the punctures 

 are uncoloured and fine, so they are not at all prominent ; the sutural line 

 vanishes at the middle at a fine point ; the sublateral line is, however, of 

 the same width until it ends just before reaching the suture ; the general 

 form is almost parallel. 



D. clio, nov. sp. 



Head bright yellow, labrum piceous, eyes black, antennae short and 

 stout, barely one-half the length of the body, black, with basal joint flavous, 

 tinged with piceous, and last joint piceous-flavous ; joint 2 short, 3 one- 

 half longer, 4 barely equal to two preceding; thorax bright yellow, convex, 

 shining, deeply bifoveate and a slight antescutellar depression, scutel 

 concolorous with thorax; elytra not plicate, pallid whitish-yellow, with 

 moderately thick, fine, piceous punctures, a narrow sutural line almost 

 attaining the apex, a sublateral humeral stripe nearly attaining the apex, 

 and a discoidal stripe, beginning just before the middle and passing the 

 convexity, black, below and feet yellow, pectus black. Length, 4^ mm. 



One example, Rio Nobilecchi Luglio, 1897, G. Boggiani (Mus. 

 Genova).
