Anguste oblongus ; niger ; niveo-squamosus ; squamis niveis 

 rostrum (parte apicali nitida excepta) caput prothoracis latera 

 corpus subtus pedesque sat dense (uihilominus maculis parvis 

 nunierosis interruptis) tegentibus et vittas insignes in corpore 

 supra formantibus, sc, — in prothorace medio, et in elytris 

 singulis (hie ad suturam, a humero fere ad apicem, et irregu- 

 lariter trifariam in parte laterali declivi); rostro utrinque 

 supra antennarum basin spina longa valida, supra oculum 

 spina trifida perlonga instructo ; oculis sat angustis ; anten- 

 narum articulo 2° 1° sat longiori ; prothorace spinis acutis 

 4-seriatim instructis; elytris apice minute divaricatis, squamis 

 brunneis (in partibus baud niveosquamosis) minus dense 

 vestitis, singulis granulis (vel potius tuberculis parvis) nitidis 

 sat dense (circiter 12-seriatim) instructis et fortiter trifariam 

 tuberculis spiniformibus et spina acuta subapicali armatis 

 (serie P prope suturam tuberculis 6 a basi retrorsum gradatim 

 majoribus, 2* sinuata tuberculis 6 magnis, 3^ postice abbrev- 

 iata tuberculis 3 magnis). [Long. 8, lat. 3g lines. 



The snowy white vitta down the middle of the prothorax 

 includes a narrow shining black line ; the p rothoracic dorsal series 

 of spines each contain j&ve gradually decreasing in size from the 

 front, the front one being bifid ; on each side of the prothorax 

 there is a long sharp spine scarcely in front of the middle and a 

 somewhat smaller one considerably behind the middle, as well as 

 3 much smaller spines which are alternated with the two long ones. 

 The front tubercle (or rather, spine) of the middle row on the elytra 

 might almost as well be regarded as a member of the external 

 row, and this would place the present species in Sir W. Macleay's 

 " Section 2 B a" of the genus, as having a compound tubercle over 

 the eye, and on each elytron three rows of spines (the outer row 

 containing at least 4), and a subapical spine. From all the others
