For the figure of this species, and the following remarks, I am 
indebted to Prof. Westwood.* 
{This curious insect differs so much from the other groups of 
Lucanide as to have rendered necessary the establishment of a 
new genus (a sub-genus) for its reception. Whilst in general 
aspect it bears a strong resemblance to the large flat Indian 
Platyprosopi, &c., it differs from them all in the 4-jointed clava of 
its antennee and dilated sides of the prothorax ; from P. Anteus, 
Hope, &c., it is distinguished by the structure of the anterior 
emarginate part of the head, and the peculiar denticulation of the 
flattened mandibles. From QOdontolabis (L. Rafflesii, Hope, &c.) 
it differs in having a spine in the middle of each of the middle 
and posterior tibize.

tubercle of the front of the head ; 6b, the eye half divided by the

The present species was described from a specimen then 
unique in my own collection by the Rev. F. W. Hope, in a paper 
read to the Society in the year 1842, upon several new species of 
Coleoptera from the Kasyah Hills collected by Dr. Cantor, and 
until a very recent period did not form part of the Hopeian Col- 
lection ; hence the species was not recorded in Mr. Hope’s Cata- 
logue of Lucanida. It has, however, been received of later years 
somewhat abundantly in collections forwarded from the above- 
named district of India.
