C. J. G-AHAN— COLEOPTEEA. 225 



The single specimen taken by Mr. Scott Elliot differs from the others in having 

 the prothorax entirely testaceous above and at the sides beneath, but I cannot find 

 that it differs in any other respect. 



Family Beenthid^. 

 Allagogus, gen. n. (Taphroderinse). 



Head scarcely broader than the anterior part of the prothorax, short and parallel- 

 sided behind the eyes, truncate behind and furnished with a balbiform neck ; rostrum 

 as long as, or longer than, the head, narrowed at the insertion of the antennae, and 

 again widened towards the apex, which is broadly rounded. Antennae somewhat short, 

 11-jointed, the last three joints longer than the others. Prothorax ovate, convex, 

 anteriorly narrowed and laterally compressed, furnished at the base with a median, 

 backwardly projecting, subconical process which fits into a deep depression at the base 

 of the elytia. Elytra slightly narrower and not much longer than the prothorax, 

 narrowly costate, strongly convex, declivous behind, rounded at the apex. Front 

 femora laterally compressed, subovate ; middle ones subclavate ; hind femora pedun- 

 culate and abruptly clavate, extending past the apex of the elytra by the whole lengtli 

 of the club, the latter strongly thickened or subtuberculate on the inner side ; hind 

 tibiae somewhat dilated; first joint of hind tarsus as long as the second and third 

 united. 



This genus ought, I think, to be placed near Cyphagogus Parry, to which it 

 has much resemblance, especially in the form of the legs, although the hind tarsi are 

 narrower and longer, with the first joint as long at least as the next two united. The 

 head is shorter than in Cyphagogus, and not narrowed behind the eyes, until the 

 constriction is reached, where the bulbiform neck begins. The basal process of the 

 prothorax distinguishes the genus from all other BrenthidcB known to me. 



Allagogus bednneus, sp. n. (Plate VII. fig. 12.) 



Reddish-brown. Head sparsely furnished with some short hairs above and longer 

 ones beneath, impressed above with a nearly obsolete median groove. Antennae with 

 the joints from the third flattened ; thiixl subtriangular, longer than broad ; fourth to 

 eighth transverse, nearly twice as broad as long ; ninth very slightly transverse ; tentlj 

 longer than broad ; these two joints are flattened above, but are thickened- near '.he 

 apex beneath, and appear somewhat deformed when seen from the side; eleventh joint 

 narrower than tenth, obtusely pointed at the apex. Prothorax nitid, marked with a 

 rather fine groove along the middle, and with a transverse groove or depression, 

 followed behind by a small transverse ridge or elevation, near the front margin ; it is 

 furnished on each side with some sparse, erect, squamiform setae. The elytra have each
