50 Major Parry’s Catalogue 
is made by Messrs. Hope, Burmeister or Reiche. In this re- 
spect I feel disposed to agree with Mr. M‘Leay; and, although 
unable to determine the species, have placed it in the catalogue 
with the genus di gus. 
Dorcus Ktuen ¢, Thomson, Cat. p. 424. 
After a careful examination of a series of specimens of the 
above insect from Assam, I feel satisfied that it must be con- 
sidered as the var. max. of D. Dehaani, the ¢ and Q of which 
species were originally described by Mr. Hope in the Trans, 
Linn. Soc. vol. xix. p. 106; the latter name will therefore be 
retained. The punctate-striate character of the elytra in the 
females of the genus, of which the small undeveloped males par- 
take, is strongly illustrated in D. Dehaanii. Some faint traces of 
this character are to be remarked in the var. max., described for 
the first time by Mr. J. Thomson. 
Dorcus DERELICTUS (?), Parry. 
D. elongatus, niger, nitidus; capite inter oculos bituberculato; 
mandibulis obsolete unidentatis; elytris lzvissimis, sub- 
parallelis ; tibiis posterioribus extus subcurvatis, inermibus, 
intermediis unidentatis. 
Long. corp. (mandib. incl.) unc. J, lin. 5. 
Hab. ind. Or, Himalaya. Coll. Parry. 
Elongate and narrow; mandibles shorter than the head, slightly 
curved, grooved above with a small tooth within near the apex. 
Head excavated and punctured in front, smooth behind; between 
the eyes are two very prominent conical tubercles. Clypeus 
prominent, triangularly emarginate. Prothorax and elytra of the 
same width, indistinctly but coarsely punctured on the sides. 
Scutellum triangular, sparsely punctate. The anterior and pos- 
terior tibize slightly curved, the latter unarmed. 
While, on the one hand, the general form and tuberculated head 
of the only specimen of the present species which has hitherto 
come under my notice are almost essentially characteristic of the 
female sex appertaining to this genus, on the other hand, the 
slender anterior, and the unarmed posterior, tibiz are so utterly 
anomalous, as to leave some doubt whether it be really a female, 
or a male with short undeveloped mandibles ; an acquaintance 
with both sexes might perhaps remove it to the genus Eurytra- 
chelus ; for the present I have placed it with Dorcus.
