By the kindness of M. Dupont, durimg my recent visit to Paris, 
(May and Jume. 1842.) I have been emabled to study this most 
interesting species in detail The male *. of which an outline, 
copied from Guerim's * Magasm~ was given in my plate I, fig. 5, 
is distinguished by two long and very robust horns m front of 
eg ie The mandibles (Plate 33. fig. 1 a) have the horny blade 
sharp and angularly dilsied m the middle om the outside; the 
maxille (fig. 15 and 15) have the upper lobe short, and much 
eurved, with the apex 3-dentate, and the outside strongly hairy ; 
the mner lobe is produced at the tip mito an acute pomt, and the 
palpi are short; the mentum (fig. 1 c) is short and broad, much 
narrowed im front and deeply emarginate with the labial palpi very 
short. The pronotum is broadest across the middle. The meso- 
sternum (fig. 1 d, 1 ¢) is comical, aeute, and porrected; the anterior 
tibie (fig. 1 f)are rather broad, with one strong tooth on the onteide 
below the aeute apex; the ungues (fig. 1g) are furnished with 2 
very short bisetose plantula, and the abdomen is channeled beneath. 
The female+ (Plate 33, fig. 1, copied from Guérin’s figure) is more 
robust than the male, with the head produced into two short horns 
—2 most smgular character; the maxillz are formed as in the 
male ; the fore tibie (fig. 1h) are externally furnished with three 
obtuse teeth; the middle and posterior tibie are much more 
strongly toothed than im the male; the abdomen is not channeled
