OMALID.K. LESTEVA. 359 



tate-striate : abdomen dilated, strongly margined, with the apex slightly 

 mucronated : legs pale red : antennae the same. 



Also a rare insect ; found in the north of England and in Scot- 

 land. 



Genus DXLVII. — Lesteva, LatreiUe. 



Antennas somewhat filiform, very slightly thickened towards the apex, the 

 basal joint large, clavate, the two following slender shorter, the remainder 

 slightly increasing in length, lanceolate-ovate, the apical one longest, acute. 

 Palpi maxillary with the second joint longest, the third subclavate, the ter- 

 minal one as long, attenuated to the tip ; labial with the apical joint slender, 

 attenuated : labrum emarginate : mandibles tridentate within : head subtri- 

 gonate : eyes moderate, prominent : ocelli sometimes two : thorax obcordate, 

 narrowed behind, not emarginate in front : body subpilose : elytra depressed 

 less than half the length of the abdomen, which is linear, and mostly acumi- 

 nated : legs rather long and slender, simple; tibice cylindric, dilated at the 

 tip ; tarsi pentamerous ; claws recurved at the base. 



The insects of the present genus depart considerably in habit 

 from the other Brachelytra, and resemble closely some of the Geode- 

 phaga, especially the genus Dromius, their elytra being very much 

 lengthened and truncate at the apex, with the abdomen projecting but 

 little; the antennae are nearly filiform, the thorax somewhat cordate, 

 body depressed; terminal joint of the palpi subulated; they have, 

 however, but one pair of maxillary palpi, and their tarsi and claws 

 are dissimilar, the former being emarginate at the apex. 



Sp. 1. dichroa. Rufa, capite, elytris apice abdominisque nigris, thorace trifo- 

 veato. (Long. corp. 2f — 3 lin.)

 Curtis, vii. pi. 303. Le. dichroa. — Steph. Nomen. 2d. edit. col. 108. 



Red, shining, glabrous, smooth: head black, with a longitudinal impression on 

 each side behind the antennae, and between them a transverse line : mouth 

 and palpi reddish : thorax rather widest in front, with a fovea on each side 

 and in the middle behind, obsoletely punctured : elytra longer and wider than 

 the thorax, pubescent, the tip slightly gibbous and black, obsoletely rugulose- 

 punctate, and longitudinally impressed towards the suture : abdomen black, 

 pubescent beneath : breast pitchy : legs pale red or testaceous : antennae 

 red, vlllose. ' 



Rare , Dr. Leach discovered it above twenty years since in the vi- 

 rinitv of Carlisle, where it has been recently taken by Mr. Hey.sham.
