Lucanoid Coleoptera. 97 



the elytra being evidently that of an immature specimen, 

 such as I now possess, and which corresponds exactly 

 with Dr. Burmeister's description of S. crnenhis, and 

 furthermore with that of 8. neotragus, Westw. The no- 

 menclature of this species will thus stand as above given. 

 The same habitat, Brasil, is given in each of the several 

 descriptions. 



Lissotes opacus, Deyr., n. sp. 



" Allied to L. ohtiisatus, Westw., a trifle smaller, more 

 opaque ; having a very distinct pruinose aspect ; punc- 

 tuation perceptibly finer and more regular. 



Mandibles of the same form, but a little less elongate, 

 the vacant space which they circumscribe at the base 

 being smaller. Head a trifle more parallel, its punctua- 

 tion finer and closer, armed on the middle of the fore- 

 head with two little shining tubercles, but slightly 

 separate from each other. 



Prothorax flatter, with the anterior angles more rounded. 



Elytra with the pruinose appearance more pronounced, 

 clothed with erect ferruginous hairs, sparsely dispersed 

 on the disc but denser at the sides ; this vestiture is much 

 more apparent than in L. ohtusatus. This species is 

 readily distinguished by its punctuation and especially 

 by its frontal tubercles. 



Hab. — ^Van Diemen's Land. Coll. Mniszech." 



(H. Deyrolle.) 



In addition to this species, I have to enumerate the 

 following species of Lissotes, of which drawings were 

 exhibited by Professor Westwood at the Meeting of our 

 Society, on the 3rd of January, 1870, and for the remarks 

 on which here given, I am indebted to him. 



'No. 1. Lissotes Lanncestoni, Westw., MS. Very nearly 

 allied to L. ohtusatus, but comparatively longer and more 

 depressed.* Hah. — North of Tasmania. 



No. 2. Lissotes latidens, Westw. MS. Female unknown. 

 Hab. — Maria Island, east coast of Tasmania. 



No. 3. Lissotes forcipula, Westw., MS. Allied to L. 

 crenatus, Westw,, in the structure of its mandibles, but 



* It is the opinion of certain Entomologists that this may ultimately 

 prove to be a mere local form of L. ohtusatus.
