the coxae, inflcxcd and received into the excavated mesosterum ; front 

 coxae transverse, without distinct trocliantin, side pieces of nieso- 

 sternum extending to the coxae, which are subquadrate, not promi- 

 uetit and separated by the narrow nicsostcrnuni ; side pieces of lucta- 

 sternum rather wide, parallel; hind coxre extending nearly to the 

 side margin, narrow, feebly sulcate behind, coxal lamina almost ob- 

 literated; abdomen with five free and equal ventral segments j legs 

 slender, spurs very small, tarsi as long as the tibiae, slender, last joint 

 without onychium, claws simple; epipleurae narrow, extending to 

 the apex ; scutellum rather large, rounded behind. 



A genus of difficult position, having a general resemblance to 

 Zenoa, but somewhat broader, with the mouth more inflexed, and the 

 mandibles smaller. It differs, moreover, from the other genera of the 

 iamily to which I have referred it, by the absence of onychiuu), and by 

 the trochantin of.thc front coxae being indistinct. It also differs more 

 essentially by the prostcrnum being prolonged behind the coxce, into 

 an inflexed point received into an excavation of the mesosternura. It 

 cannot be referred elsewhere in the series, unless it be to the tribe 

 Euhriini of Dasc^flidse, to the species of which it has no resemblance 

 in appearance, nor in the more special characters. 



B. fulva. — Yellowish-brown, shining; head punctured, feebly channelled, 

 transversely impressed betv/een the eyes; prothorax transverse, trapezoidal, 

 punctured, feebly channelled, hind angles prolonged, acute, subcarinate; 

 elytra slightly wider than the prothorax, strongly margined, punctured, feebly 

 striate, obtusely rounded behind ; beneath shining, finely punctured and pubes- 

 cent. Length .20 inch; 5 mm.

AKAEOPUS, n. g. {Dasa/ltidce.) 

 Body elongate, oval, convex, rather acute before and behind, finely 

 punctured, densely clothed with prostrate hair. Head dcflexed, mod- 

 erate in size, front convex, with the transverse suture distinct, 

 epistoma entirely corneous. Mouth rather prominent; labrum con- 

 vex, broader thafl long, rounded and feebly emarginate in front. 

 Mandibles curved, acute at tip, visible beyond the labrum. Antennie 

 inserted upon the front at the sides behind the base of the mandibles, 

 but not under a prominence, 1 l-jointed, rather stout, extending a 

 little beyond the base of the prothorax, subserrate; 1st joint stout, 

 shorter than 3d; 2d globose, 3d subtriangular a little longer than the 

 4th ; 4 — lU equal in length ; 11th a little longer; eyes rounded, finely 

 granulated; maxillary palpi not dilated, last joint a little longer;
