﻿of Lucanoid Coleoptera. 63 



Lissotes, This insect appears to represent, on the southern coast 

 of Africa, those species from S. America and N. Holland belong- 

 ing to the genera above alluded to. 



Lissotes Menalcas, Westw. 



This species appears to form the connecting link, through the 

 genus Nig'idius, between the Dorcidce and Figulidce. 



L. Howittanus, Westw., exhibits a marked difference from 

 L. Menalcas in the character of the prothorax ; but its similarity 

 to that species in other respects, and its close affinity in appear- 

 ance to Nigtdius, have induced me to locate it for the present at 

 the end of the genus Lissotes, immediately preceding the Figulidce. 



NiGiDius coRNUTUs $, $, M'Lcay, Hor. Ent. i. p. 109. 

 N. cornutus, ater, nitidus ; mandibulis tridentatis ; clypeo punc- 

 tato, antice mucronato ; elytris inter strias elevatis, triplici 

 punctorum impressorum ordine instructis, apicibus punctatis ; 

 tibiis anticis 7-dentatis. 

 $ mandibularum margine supero et externo in ramum cor- 



nutum producto. 

 2 mandibulis brevioribus, baud cornu supero instructis. 

 A second description of this species will be found in the Ento- 

 mological Magazine, vol. v. p. 264, by Prof. Westwood, taken from 

 a specimen in the British Museum, stated to have been received 

 from Mr. M'Leay, and from Australia. Having long doubted 

 the accuracy of this habitat, no specimens of it being contained 

 in the numerous collections of Australian Coleoptera which have 

 reached this country, I have only recently ascertained the true 

 habitat of the species in question, specimens in the collections of 

 W. W. Saunders, Esq., and of Count Mniszech, from Cambodia 

 and Malacca, proving, upon comparison, to be identical with that 

 in the British Museum. 



NiGiDius OBEsus $ , Parry. 



N. convexus, brevis, nigerrimus, nitidus ; capite utrinque infra 

 oculos auriculato ; mandibulis subrecurvis, intus ad basin 

 processu bifido productis, extus pone medium dente parvo 

 obtuso armatis ; prothorace crebre grosseque punctato, in 

 medio obsolete late longitudinaliter caniculato, angulis anticis 

 simplicibus ; elytris brevibus, convexis, rugoso-punctatis, for- 

 titer sulcatis, interstitiis laevibus. 



Hab. Penang, Malacca.
