10 Major Parry’s Catalogue 
Lucanus Smiru @, Parry (@ ignota). (Pl. X. fig. 2.) 
L. nigro-fuscus, subtus dense villosus ; elytris rufo-ferrugineis, 
nitidis, villosulis; mandibulis apicibus furcatis, intus ante 
medium lobo tridentato armatis. 
Long. corp. une. 1, lin. 7. 
Hab. Ind. Sept. Coll. Parry. 
Allied to Z. villosus, Hope. Mandibles subquadrate, outer 
margin sinuate; beyond the middle a tridentate lobe ; the tip of 
each mandible furcate. Clypeus triangular, slightly excavated. 
Base of mandibles, head, thorax and elytra (when in good con- 
dition) with short scattered hairs. Head with ridges and crest 
much as in L. villosus, but the lateral ridges not so elevated. 
Femora and tibie with a ferruginous vitta, widely separated, the 
posterior with two teeth. I have dedicated this new species to 
F. Smith, Esq., the well-known Hymenopterist, and President of 
the Entomological Society. 
Lucanus MAcuLIFEMoRATUS, Motschulsky, Etudes Ent. 1861. 
? sericans (De Haan, MS.), Voll. Tijd. v. Ent. iv. 103. 
Specimens of this new and rare species from Japan are in the 
museums of Leyden and the Zool. Soc. Amsterdam, @, ¢, and 
in the collections of Count Mniszech and myself. The habitat 
Java, ascribed to ZL. sericans by M. van Vollenhoven, appears to be 
erroneous; the latter insect is probably the var. minor of Lucanus 
maculifemoratus. 
With reference to Lucanus Hircus, Sturm, Cat. (Java), I have 
not been able to obtain any information. 
Gen. Ruxtus, Parry (gen. nov.). 
Caput transversum, angustum, antice depressum. Mandibulee 
falcatee, maximee, ad basin fortiter dilatatea. Antenne 
clava mediocri quadri-articulata. Prothorax lateribus in 
medio armatis. Corpus elongatum, subparallelum. Tibize 
posticze inermes. 
Hexarthrio affine genus. Nomen a gigante Rheto, uno e 
Titanis, derivatum, 
The principal distinctive characters above given of this genus 
. present an interesting connecting link between Lucanus and Hex- 
arthrius ; on the one hand, the moderately developed clava of its 
antennee, the flat and generally depressed form of its head, and 
its unarmed posterior tibia, separate it from Lucanus ; whilst on 
the other hand it is distinguished from Hexarthrius by the 4-jointed 
clave of the antenne, and its laterally-armed prothorax.
