370 Prof. Westwood on 
circular depression, with a tubercle on each side near the 
base of the mandibles. The latter are short, subtriangular, 
with two teeth on the inner edge. 
Plate IX. fig. 7a, represents the head of the male (re- 
duced in size in comparison with fig. 7c, which represents 
the head of the female). The broad tooth on the inner 
edge of each of the mandibles of the males, is more con- 
spicuous in some individuals than in others; thus, in my 
figure of the male above referred to, it is scarcely per- 
ceivable. 
The maxille in both sexes are simple, those of the 
female being destitute of the strong hook at the extremity 
of the inner lobe. Fig. 7b, represents the maxilla of the 
male; and 7d, that of the female. 
The prothorax of the female is transverse, with the 
lateral margins rounded, the anterior portion being as 
wide as the hinder; the disc is covered with punctures, 
those of the centre being smaller than the rest, without 
any of the smooth spaces or the rude punctures seen in 
parts of the prothorax of the male. The elytra are much 
more punctate than the male, the punctures extending 
to the extremity, and there is a broad, flat, smooth stria 
on each elytron adjoining the suture, as well as two on 
the disc of each, separated by punctures, which gradually 
disappear beyond their middle; the legs resemble those 
of the male, the anterior tibie of the male being armed 
on the outer edge with several (three or four) minute 
teeth, which are not represented in the figure published 
in Trans. Ent. Soc. drd ser., vol. I. pl. xxi. f. 1. The an- 
terior tibiz of the female exactly resemble those of the 
male. 
In several of his memoirs on this family (especially in 
the Transactions of the Entomological Society for 1864 
and 1870), Major Parry has suggested that the unique 
insect in the British Museum from Moreton Bay, which 
I described under the name of Dorcus Pelorides (Trans. 
Ent. Soc. 3rd ser. vol. I. pl. xxi. fig. 2) may be the 
female of L. Howittanus. This supposition is now dis- 
proved by the discovery of the true female by Dr. Howitt. 
The chief distinctions between these two females may be 
thus contrasted.
