This species has the quasi-front angles of its prothorax 

 extremely obtuse (as in fossus, Newm.), the true lateral margins 

 of the segment converging forward from them much less strongly 

 than in the three preceding species so that there is a much longer 

 piece of the pronotum in front of them ; they are, however, 

 quite distinctly angles and not rounded ojS' as they are in the 

 species that I take to be vidtiaius, Pasc. The elytra! sculpture is 

 much like that of the latter species from which however it i^ 

 readily distinguished not only by the better defined quasi fronv 

 angles of the prothorax, but also by the very much less close 

 puncturation of the head.

This species differs from all the preceding (of the group having 

 the pronotum closely punctured) by the lateral outline being 

 rounded at the part where they have the angles that I have 

 called the quasi-front angles of the pronotum. In this respect it 

 agrees with Z), viditaiiis, Pasc, from which it differs inter alia 

 by the third interstice of its elytra being cariniform at the base 

 as well as the apex, and by the sculpture of its head, closer and 

 quite evidently rugulose and not longitudinally sulcate in the 

 front part : the unique type moreover is much smaller than any 

 specimen of vidua fits that I have seen. The obsolete punctura- 

 tion of the elytral interstices is suggestive of ig)iarns, Pasc, but 

 the brief description of that species implies that the third inter- 

 stice of the elytra is entirely cariniform, and represents the 

 insect as differently colored and much larger. There is little in 

 the description of _D. colydioides, Pasc, to distinguish that species 

 from the present one as it is an extremely short and vague- 

 description, but it indicates colydioides as very much smaller, and
