hinder part of the thorax, but these punctures are confluent in the longitudinal 
direction. O. striatus presents a nearly similar condition of the sculpturing, but it is 
scarcely so dense and delicate on the disk of the thorax. The elytra are rather less 
convex in QO. exaratus than in the other two species ; in all they are covered by sharply 
impressed lines, separated by minute longitudinal ridges, besides which in O. striatus 
the dorsal surface of each elytron presents six equidistant and equally developed 
cost, and a row of somewhat isolated punctures between them. In O, sulcatus the 
intermediate coste—i.e., the first (or that nearest the suture), third and fifth—are 
wanting, or rather they are not distinguishable (excepting in a slight degree in certain 
parts) from the very minute longitudinal ridges filling up the interspaces ; of these 
there are five, the central one representing the costa ; there are six rows of somewhat 
isolated punctures, as in O. striatus. O. exaratus presents an intermediate condition, 
for each elytron has six cost, but the alternate ones are rather less raised ; the punc- 
tures are much larger in their transverse diameter, filling up almost the whole inter- 
space between the coste. The first, third and fifth coste (being those which are less 
elevated) are depressed, and punctured in parts. There are other differences in these 
insects observable in the structure of the legs and antenn, but those already pointed 
out will render them easily distinguishable.”

Further Remarks on Mr. James Thomson’s ‘ Catalogue of Lucanide. 
“ Mr. James Thomson having kindly placed at my disposal for examination the 
type-specimens of some interesting species of Lucanoid Coleoptera formerly belonging 
to Count Dejean’s collection, as well as of those species described by himself in bis 
recently-published ‘ Catalogue of the Lucanide, I have drawn up a tabular statement 
upon the synonymy of the species in question. To this I have added a few observa- 
tions, and the whole may be considered as an Addendum to my Remarks upon Mr. 
Thomson’s ‘ Catalogue’ which have been already published in the Society’s ‘ Trans- 
actions. I am now able to state that the opinion therein expressed, that several of 
the species in question had previously been published, has, after a careful examination 
of the type-specimens, been fully corroborated. To those Members who are more par- 
ticularly interested in the Lucanoid Coleoptera, the types of Count Dejean’s species, 
now exhibited, together with the handwriting of this celebrated Entomologist, cannot 
but prove interesting.
