XII. Characters of seven nondescript Lucanoid Coleop- 
tera, and remarks upon the genera Lissotes, 
Nigidius and Figulus. By Major F. J. Sidney 
Parry, F.L.S. 
[Read 7th April, 1873.] 
Lucanus Dyhowski, $ , Parry, (var. max.). 
L. nigro-brunneus, mandibulis robustis, capite pro- 
tlioraceque paulo longioribus, intus irregulariter quinque- 
dentatis, corpore subtus dense villoso, femoribus infra 
rubro-maculatis. 
Closely allied to L. Hopei (vide Trans. Ent. Soc. 3rd Ser. 
vol. ii. p. 9, pi. vi. fig. 2), but the following differences upon 
comparison are found to be apparent. The mandibles are 
somewhat longer, less circumflex, and furnished with seven 
teeth instead of five, these being less reguJarly distributed : 
the basal tooth inclining internally, instead of externally as 
in L. Hopei; the posterior angles of the head are con- 
siderably more rounded ; the suberect lobe, so conspicuous 
in the centre of the anterior margin of the head in L. 
Hopei, is also entirely wanting; moreover, the sides of 
the thorax are much less sinuate, with the anterior angles 
less produced. I have but little doubt that both these 
species in a normal condition are strongly pubescent upon 
the upper surface. I am indebted to Count Mniszech for 
the opportunity of notifying this interesting species. It 
has been named after a young and zealous Polish entomo- 
logist by whom it was captured, with other interesting 
novelties, in the district of the Amur River, Dauria, and 
transmitted to the Mu^seum of Natural History in Warsaw. 
A specimen of L. Dybowski is to be met with among 
the insects recently sent to the Paris museum by Mons.
