The <J of this species is not known; two specimens have been 

 sent to me by Mr. Lea, together with the preceding species, as 

 being g and Q of the same species, which, after all, is not quite 

 impossible ; but without mentioning the antennae, which are 

 known to vary immensely in the g and Q of the same species, 

 there are so many and so important other differences that it 

 seems to me difficult and improbable that the two belong to the 

 same species; the head is much broader and shorter with a fine 

 rugose punctuation; the prothorax is short and broad with a 

 shallow longitudinal sulcus; the abdomen is broader, shorter and 

 rounded behind, in the sides, before the middle being abruptly and 

 angularly constricted, so as to appear divided into two parts; the 

 carina of the base is much shorter, and its sides are oblique and 

 convergent so as to form an elongated triangle; the excavation 

 of the abdomen is large, deep, but transverse.
