﻿10 Major Parry's Catalogue 



LucANUs Smitiiii $ , Parry ( ? ignota). (PI. X. fig. 2.) 



L. nigro-fusciis, subtus dense villosus ; elytris rufo-ferrugineis, 

 nitidis, villosulis ; mandibulis apicibus furcatis, intus ante 

 medium lobo tridentato armatis. 



Long. Corp. unc. 1, lin. 7. 



Hab. Ind. Sept. Coll. Parry. 



Allied to L. 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 tibiae with a ferruginous vitta, widely separated, the 

 posterior wiih 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. 

 ■fsericans (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 L. sericans by M. van VoUenhoven, appears to be 

 erroneous ; the latter insect is probably the var. minor of Lucanus 

 maculifemoratus. 



With reference to Lucanus Ilircus, Sturm, Cat. (Java), I have 

 not been able to obtain any information. 



Gen. Rh.t-.tus, Parry (gen. nov.). 

 Caput transversum, angustum, antice depressum. Mandibulae 

 falcatae, maxima?, ad basin fortiter dilatatae. Antennae 

 clava mediocri quadri-articulata. Prothorax lateribus in 

 medio armatis. Corpus elongatum, subparallelum. Tibiae 

 posticac! incrmes. 

 Ilcxarlhrio afline genus. Nomen a gigante Rhaeto, uno e 



Titanis, derivatum. 

 The principal distinctive characters above given of this genus 

 present an interesting connecting link between Lucanus and Hex- 

 arlhrius ; on the one hand, the moderately developed clava of its 

 antennae, the flat and generally depressed form of its head, and 

 its unarmed posterior tibiae, separate it from Lucanus ; whilst on 

 the other hand it is distinguished from Ilexarthrius by the 4*jointed 

 clavac of the antennae, and its laterally-armed prothorax.
