of nondesci'ipt Lucanoid Coleoptera, Sfc. 337 
sides present a remarkable difference in coloration, for in- 
stead of being, as in O. Brookeanus, uniformly testaceous, 
it is variegated. The wliole of the reflexed margin, to- 
gether with the epipleuraj, are black, as also the prothorax, 
save two indistinct lateral rufous patches. 
This interesting addition to the Lucanoid Coleoptera 
was discovered by H. Lowe, Esq., a gentleman who has 
contributed so much to our knowledge of Bornean ento- 
mology.

M. Blanchardi is readily distinguished from its allied 
species, M. cinnamomeus , M. castaneus and M. foveatuSy 
by its very pale luteous coloration, the form and armature 
of the mandibles, and especially by the narrow black 
central line exhibited on the disk of the prothorax ; this 
character occurs only, to my knowledge, in two other 
insects belonging to this group, viz., the very rare Proso- 
pocoilus suturalis of Oliv., and in P. Mohniki, now 
described for the first time. To P. occipitalis, M. Blan- 
chardi also bears a general resemblance, but the binodose 
front of the head necessitates its location in the genus 
Metopodontus. I may remark that I have recently seen 
a specimen of this insect, ticketed M. Dauricus, Mot- 
schulsky, in the collection of the Jardin des Plantes, 
collected, with various other interesting novelties, by
