having the yellow marginal band of the elytra not narrowed 

 at the apex. The large males have four or five teeth beyond 

 the middle of the mandibles (besides the apical furcation) ; 

 the large triangular tooth at the base of the mandibles is rela- 

 tively longer, straight on its inner margin (not curved in at 

 its apex), and denticulate. The females are very difficult to 

 distinguish from those of V. limhatus ; the lines of punctures 

 on the elytra are, however, more distinct. The metasternum 

 is dull in both species ; in C. limhatus there are numerous shal- 

 low horseshoe punctures, which become crowded together at 

 the side next to the epipleura. In 0. cinctus these punctures 

 are more sharply defined and round, and not confluent, except 

 perhaps a single line next to the epipleura. 



In the late Major Parry's Catalogue of Lucanidce (Trans. 

 Ent. Soc. Lond. 1864, p. 22) there is the following note 

 respecting C. cinctus : — 



" This species is also, according to Mr. Wallace, found in 

 the islands of New Guinea, Ki, and Arou, and must be con- 

 sidered as very questionably distinct from C hison, differing 

 in having the four ])osterior femora black beneath, and the 

 anterior with a small rufous spot, whereas in C. bison the 

 rufous patch exists on all the femora." 



Two examples from Major Parry's collection are now in the 

 British Museum ; one of these (from Cape York) is C. lim- 

 hatus^ the other (without locality) is a variety of C. bison. 

 The statement that C. cinctus diff'ers from C. bison in having 

 a red spot only on the front femora appears to have arisen from 

 a misunderstanding of Montrouzier's description. lie men- 

 tions no red spot, but " uue tache fauve, dore sur le devant 

 des cuisses ant^rieures," which clearly refers to a spot of 

 golden pubescence, usual on the front of the femora, and not 

 to a red spot on the back of the femur. 



XLIX. — Descriptions of two new Species of Coptengis 

 (Coleoptera, Erotylidai). By Charles O. Waterhouse. 



The British Museum has received two species of the genus 

 Coptengis which appear to be undescribed, and for which I 

 propose the names C. Curtisii and C. Melvilli. 



Coptengis Curtisii. 

 Purpureo-cuprascens, nitidissimus, immaculatus j pedibus viridi- 



seneis. 

 Long. 19-22 millim. 



This species is closely allied to C. Sheppardi, but is dis- 

 tinguished at once by its totally different colouring (being of
