" Closely allied to pumicosa, which it resembles ia the shape of the 

 body, uustriated maadibles aad puacturation intermixed with fine 

 striae ; the latter, however, are more numerous and stronger, giving 

 this species a duller appearance. The abdomen is wholly dull, even 

 the apical segments. In pumicosa the last three segments are 

 shining, the antepenultimate less strongly striated than the pre* 

 ceding, and the following segments only punctured."

" This species is very similar to cavernosa, but differs from it in the 

 following characters : the whole body is covered with a very fine 

 recumbent yellow or yellowish-red pubescence, which gives the body 

 when seen from the side a yellow silky tinge. The sculpture of the 

 head is not so coarse as in cavernosa, the punctures are farther apart 

 and are not coaflueat ; the puactures are also shallower. The space 

 betweeu the puactures is finely striate. The apex of the frontal 

 carinae is smooth, shining, and of a reddish colour ; the mandibles 

 are dark red, shiaing, aot striated but puactured with rather coarse 

 aad fine puactures intermixed. The head is somewhat longer than 

 in cavernosa. The clypeus is sharply carinate. The punctures of 

 the thorax are large and shallow, the interspace rugulose. The node 

 of the petiole is slightly rounded in front, the posterior face is 

 vertical but the dorsal margin of same widely emarginate, flat above, 

 narrower ia froat thaa behiad; below, the ventral lamella is produced
