D. torridus, sp, nov. La?te a^neus, corpore subtus antice femor- 

 ibusque cyaneis ; pilis densis albis nigrisque maculatim dis- 

 positis vestitus ; capite prothoraceque valde in?equalibus, 

 striolato-alveolatis ; scutello magno elongate triangular! ; 

 elytris singulis costam discoidalem ferentibus, acervatim

 The sculpture of the upper surface is to a great extent con- 

 cealed by dense pubescence, forming a pattern of marbled appear- 

 ance ; this pubescence takes the form of a transverse white fascia 

 between the eyes, a dense white mass on each side of the pro- 

 thorax, a number of smaller white spots on the elytra (some of 

 which range themselves into two fasciae behind the middle), some 

 large black spots mostly in the hinder half of the elytra, a lateral 

 white spot on the hind coxae, a dense white mass on either side 

 of the basal two ventral segments and some smaller white spots 

 on the other ventral segments. The crown of the head bears- 

 two rounded and moderately conspicuous gibbosities ; the pro- 

 thorax is widely elevated do^^'n the middle line, the elevated 

 portion bearing a ridge-like tubercle on either side in its hinder 

 half ; the elytra are much flattened (or almost concave, between 

 the suture and the discoidal ridge. The sculpture of the pro- 

 thorax is arranged in concentric lines. The carina within the 

 border of the prothorax on either side is elongate and sinuous.

 The arrangement of the pubescence is very distincti\'e ; the 

 pubescence is thin and little noticeable except on the sides of the 

 prothorax and tlie whole abdomen (except the apical two seg- 

 ments), which are densely clothed with tolerably long silvery- 

 white soft hairs. The chief ine(pialities on the head are a strong 

 sulcus down the middle, a large transverse excavation between
