﻿56 Major Parry's Catalogue 



posterior angles is an oval polislied patch. The elytra and scu- 

 tellum are punctured at the base; the former are punctate-striate, 

 the 2nd and 7th, 3rd and 4th, and also the 5th and 6th striae 

 being united at their extremities. The anterior tibiae are serrated 

 along the outer margin, with two strong teeth at the apex ; the 

 middle tibiae are armed with two spines, and the posterior ones 

 with a single spine in the middle of the outer edge. 



This species is most nearly allied to Dorcus capitntiis,* Westw. 

 (Trans. Ent. See. iv, 275), but differs from the large males of 

 that species in the much-advanced position of the strong tooth of 

 the mandibles, and in the very slight development of the tubercle 

 on each side of the disc of the head before the eyes ; agreeing in 

 this respect with D. parnllelus, Hope (Cat. Lucan.), from the 

 Khasyah Hills, whilst Major Parry's insect is from Darjeeling. 

 The D. parallclus is indeed considered by Major Parry to be a 

 small variety of D. capilalus ; but the latter is from Malacca 

 and Prince of Wales' Island, and I should be inclined to regard 

 D. parallclus rather as the varietas minor of Z). lah'dis. D. s'niister 

 (Hope, Cat. Lucan.), also from Prince of Wales' Island, is, doubt- 

 less, the female of Z). capitatus, as Major Parry suggests. 1 have 

 also scarcely any doubt that the female insect named D. Malaba- 

 r'lcus (Hope, MS. ; Westw. Trans. Ent. Soc. iv. 27(5) is identical 

 withZ). sinister ; and in like manner I also consider that D. a'qualis 

 (Hope, MS. ; Westw. Trans. Ent. Soc. iv. 270) is most probably 

 identical with D. parallelus. 



D. labilis is also closely allied to D. Eschscholtzii, Hope, but 

 that is a considerably smaller insect, with a more polished upper 

 surface, the anterior lateral angles of the head destitute of 

 tubercles, and the i)ronotum destitute of the punctured impression 

 in the middle.

iTlGus PLATYODON S, Parry (var. max.) (PI. X. fig. 1.) 



JE. niger, parum nitidus ; mandibulis falcatis, ad basin dente 

 magno trifido armatis ; capite magno, transverso, antice in 

 medio profiuide emarginato ; elytris punctato-striatis ; scutello 

 sparsim et fortitcr j)uiictato ; tibiis anticis serratis denticulis 



• In the description and figure of this species in the 4lli volume of these 

 Transnclions, the middle tib a; are describeil as possessing only a single spine on 

 the outer edge. They, however, agiee in this respect with t), labilii.
