slightly damaged.) The underside of the bodj and the legs 

 have a faint greyish pile, and there is a rust-brown pubes- 

 cent spot on the side of each abdominal segment, as well as a 

 few spots of the same kind on the breast. 



The style of marking in this species reminds one more of 

 species of Hammoderus^ a closely allied genus, than of 

 Tceniotes. The structural characters, however, leave no room 

 for doubt, and it may be here remarked that the form of pro- 

 sternum is one of the best characters for distinguishing the 

 two genera ; in Hammoderus the prosternum is simple, in 

 Tceniotes it is of the form described above in a footnote.

Long. ( d ) 30, ( ? ) 40 mm. 



Hab. Mexico. 



In style of marking and arrangement of pubescence closely 

 resembles D. nivea, Bates. The pubescence is yellowish in 

 colour, not white, the pubescent vittas on the front of the head 

 are broader, and the latter is itself distinctly wider than in D. 

 nivea. The upper part of the head wants the lateral pubescent 

 vittge which are present in that species. The mesosternal 

 process is horizontal below and is produced in front but very 

 little beyond the anterior vertical wall of the mesosternum ; in 

 D. nivea^ on the other hand, it is very strongly and obliquely 

 produced downwards and forwards.

 2 • Prothorace lateribus obtuse tuberculatis nee spinosis. 



Hab. Mexico (Palenque). 



In this variety, of which there is a single female specimen 

 in the Museum collection, the lateral spines of the thorax are 

 wanting and are replaced by obtuse tubercles. The longitu- 

 dinal white and ochraceous bands on the elytra are all very 

 much interrupted. 



The absence of the lateral spines on the prothorax is the 

 more noteworthy since in some females of another species of 

 the genus {D. nivea) ^ as mentioned by Bates, the same kind 

 of variation occurs.
