452 DR. F. LEUTHNER ON THE ODONTOLABINI. 



L. gazella (sinensis), being the female of 0. hicolor, Oliv., which occurs in Siam (Assam (1), 

 Nepal 1), Malacca, and Borneo. Westwood speaks of this type as follows : — " This speci- 

 men is a female, and differs only from the insect represented in the accompanying plate, 

 fig. 4, and M. Guerin's figure of his Lucanus clelessertii (Voy. de Delessert, Ins. pi. xii. 

 fig. 3), in having the black colour jjrecisely occupying half of each elytron, being thus 

 intermediate between these two specimens (sc. 0. gazella sinensis and 0. cuvera). 1 

 observed also that the spine terminating the posterior tibiae is more bent upon the base 

 of the tarsi even than in my fig. 4. I have seen no male which will agree with this 

 intermediate female in the colouring of the elytra &c." (Comp. p. 465.) 



No doubt can exist respecting the authenticity of the Fabrician type, as it entirely 

 agrees vvith the description of Fabricius and with the figure of Olivier, and I have 

 therefore retained Westwood's name for the present species.

Male. Similar to that of 0. sinensis. Deep black, or dark chestnut-brown, but elytra 

 yellow, with a Y-shaped black or chestnut-brown mark beginning at the shoulders and 

 extending evenly to the tip ; rim of the elytra yellow beneath ; head and thorax as in 

 0. sinensis, but more finely punctured on the upper side, and shining ; front tibia; in 

 large specimens with five and in smaller ones with from three to five teeth above the 

 terminal fork. 



Mandibles. 



1. Forma telodonta. — As in 0. sinensis. — Var. cuvera, s. str., Hope (fig. 7). 



2. Forma mcsodonta. — Only diff'ers from 0. sinensis in the colour of the elytra. — 

 \jix. 2^>'mse]Ji)ii, Hope (fig. 8). 



3. Forma piodonta. — As in 0. sinensis (fig. 9). — Var. saundersi, Hope.

 thorax more convex above, much more finely punctured, and shining ; sides bispinose, 

 the spines not so pointed as in 0. sinensis ; outline diff'erent from that of 0. sinensis ;
