and various observations are introduced both by Dr. Burmeister and 

 the author, to show that it belongs to the family of longicoms.* 

 Plate XI represents two species of Papilio. 



1. Papilio Gijas. Fore wings slightly hooked, hind wings tailed: 

 above brown with a darker margin, which has a series of obscure yel- 

 lowish spots, those in the hind wings being lunulate ; the fore wings 

 have in addition three nearly round discoidal spots of the same colour, 

 and the hind wings a round, blue, anal spot. Expansion of the wings 

 4|- inches. Inhabits Assam : the specimen is in Mr. Solly's cabinet. 

 (Id. i. 41, tab. xi. fig. 1). 



2. Papilio Cloanthus. Fore wings acute, hind wings tailed: black- 

 ish, with a large central space common to both wings, silvery green ; 

 this is divided into spots towards the apex of the fore wings, and the 

 hind wings have a row of sub-marginal spots of the same colour. Ex- 

 pansion of the wings Sg^ inches. Inhabits the northern countries of 

 India, and is in the cabinet of the British Museum. (Id. i. 42, tab. 

 xi. fig. 2). 



Plate XII. represents new heteromerous beetles, but I find no refe- 

 rence from the text to the plate. 



1. Cyphaleus formosiis. The genus Cyphaleus has the clypeus 

 projecting on each side in front of the eyes, yet scarcely covering the 

 base of the antennoe, which are as long as the head and half the pro- 

 thorax ; the joints towards the apex being shorter and stouter than 

 the rest : mandibles subtrigonate, bifid, and have an interior membra- 

 nous process on the inner edge : maxillae with the lacinia hooked and 

 acute, the galea large, obtuse and hairy, the palpi with the terminal 

 joint securiform: the labipalpi are short, their terminal joint subsecu- 

 form : prothorax rather wider posteriorly, with sharp angles : elytra 

 wider than prothorax, completely covering the abdomen. The spe- 

 cies is black and punctured, the basal half of the elytra green, sur- 

 rounded with purple, the apical portion violet-black. Length Up- 

 lines. Inhabits New Holland : in Mr. Hope's cabinet. (Id. i. 43). 



* This insect belongs to that natural order which I have called Cucujites, in which 

 great variation takes place in the form of the allux or third, and in the development 

 of the arthrium or fourth tarsal joint : the typical longicorn beetles or Cerambycites 

 have the allux deeply cleft and bilobed, and the arthrium rudimentary only. The 

 Prionus pilosicollis of Hope, alluded to by Mr. Westwood, forms, together with a se- 

 cond described species — glabricollis of NeA\Tnan, the genus Sceleocantha, Newman, 

 'Ann. Nat. Hist.' v. 14 ; and Cantharocnemis, of which the author speaks as an unde- 

 scribed genus, was carefully described in a paper read before the Entomological Soci- 

 ety of France in 1832, and published in the 1st number of the Transactions of that 

 Society, i. 132
