340 Major F. J. Sidney Parry on the characters 
exceedingly small, transverse. Mandibles short, tridentate 
at the apex. Tarsi short. 
I am indebted to IM. Henri Dep'olle for permission to 
incorporate the description of the $ in the present paper, 
and to the kindness of Mr. F. Pascoe to add a description 
of the ? . A single example of the $ exists in the col- 
lection of Count Mniszech, and both sexes in that of Mr. 
Pascoe, their habitat being the Chatham Islands, situate 
about 400 miles from the eastern coast of New Zealand. 
I avail myself of the opportunity to add a few remarks 
upon the species composing the genus. 
The genus Lissotes was proposed by Professor "West- 
wood (vide Trans. Ent. Soc. N. S. iii. p. 213), and con- 
tains the numerous Australian species belonging to the 
family of the Dorcidce, which are represented in South 
America by the Sclerostomi of Dr. Burmeister (vide Hand- 
buch der Entomologie), and exhibit such diversity of form 
that I am now disposed to modify the grouping in my Cata- 
logue of the several species at present known. 
Professor Westwood (loc. cit., p. 214) distributes the 
species into two sections, characterized by the form of the 
mandibles ; but subsequently, in describing some interest- 
ing new species (Trans. Ent. Soc. 1871, p. 353), he pro- 
posed other characters as distinguishing the Tasmanian 
species. It is upon these last characters that I have based 
the follomng tabular arrangement, embracing the whole of 
the Australian species at present kno-RTi. I admit it is 
not quite satisfactory, since it involves the approximation 
of somewhat incongruous forms, yet it is nevertheless the 
best I can at present offer : — 
A. Posterior angles of prothorax oblique, with a prominent angle opposite 
the shoulders of elytra. 
a. Fore margin of prothorax anteriorily produced in the middle. 
* Prothorax with a small central polished tubercle. L. can- 
croides: L. rctlculatiis. 
•* Prothorax with two small tubercles conjoined in middle of 
front margin. L. Menalcas: L. suhtuhercxdatiis. 
•** Prothorax with produced lobe slightly emarginate. L.punc- 
tiilatns. L. Korcs Zealand'icB. 
i. Fore margin of the prothorax straight ; front of the head strongly 
i-etusc. L. capita: L. pelorides {^): L. cvrvlcornis. 
B. Posterior lateral margins of prothorax rounded. L. Launccstoni: L. 
ootumtus : L. opaci/s : L. lat ideas : L.forci2)ula: L.ci'enatus: 
L. subcrenatus ( J )•• L.fuscicorms. 
Nigidius cribricollis, $?, Parry. (PL V. fig. 6.) 
A^. Delegorguei proxiraus, niger, vix nitidus, prothoracis 
disco, ubique rcgulariter punctato, in medio le\ater sulcato, 
angulis anticis profunde incisis.
