Lucanoid Coleoptera. 95" 



species of Dorcus, especially in the toothing of the legs, 

 and in the produced clypeus, but its broader form and 

 rounded thorax remove it from all of these /^ 



I fully coincide with the author, as to this species 

 being nearer in affinity with the Dorcidce than with either 

 the Lucanidoi, Odontolahidce, or Gladognathidce. Taking 

 into consideration the several characters above-men- 

 tioned, and the small head and mandibles, in the only 

 male specimen known to me, Avhich is probably the var. 

 max., I am induced to place this species at the head of 

 the second division of the Dorcidce, under the generic 

 name of Pseudodorcus. 



Sclerostomus tristis, Dej^r., n. sp. 



^'Allied to 8. Bacchus, as regards size and form, but 

 more depressed, and more opaque. 



Mandibles somewhat similar, but presenting a kind of 

 inclined plane from the external margin to the interior 

 teeth, with a rounded tubercle in the middle of this 

 plane in lieu of the ridge which exists in 8. Bacchus. 



Head nearly similar, except the post-ocular tubercles 

 which are less developed laterally, and much more so 

 posteriorly. 



Prothorax with its sides more parallel, especially be- 

 hind; its posterior angles, although likewise truncate, 

 are much more pronounced. 



Scutellum half the size of that of its congener. 



Elytra flatter, more opaque, punctuation similar to 

 that of 8. Bacchus. Beneath much more opaque. 



Finally, this species is distinguished by its general 

 form, its more quadrate prothorax, its very small scutel- 

 lum, and its generally more opaque aspect.

8clerostomus marginipennis, Deyr., n. sp. 



" Allied to 8. Lessonii, Buq., and Philippi, Westw. ; 

 more nearly related to the latter by the squamose lateral 

 bands of the elytra, which reach the margin. Of the 

 same form as 8. PhtUpiti, but a trifle smaller, and more
