26 ADEPHAGA. [Bwscina. 



possess two genera comprising one species each, Broscus and Miscodera, 

 both of which have the firet three joints of the anterior tarsi of the male' 

 dilated, the former rather strongly, the latter only moderately ; no con- 

 fusion, however, can arise, as our species are easily distinguished by 

 having the hind body pedunculate, and by having the scutellum situated 

 in the peduncle, and not let into the base of the elytra ; as the neck of 

 the thorax covers the peduncle either wholly or partially, the thorax 

 requires to be bent forward in order to render the character quite dis- 

 tinct ; the first four joints of the antennae are glabrous, the rest 

 pubescent. 



I. Head narrower than tborax ; penultimate joint of maxillary 

 palpi strongly narrowed behind, somewhat dilated in trout ; 



base of thorax not fringed Miscodeea, JF^cA. 



II. Head as broad as thorax ; penultimate joint of maxillary palpi 

 normal ; base of thorax fringed with a row of close-set fine 



bristles Beoscus, Pans. 



MISCODEZIA, Eschscholtz. 



This genus comprises five species from Northern Europe and North 

 America. Dr. Horn includes three of the species under M. arcHca, and 

 considers that there are only two species, M. aretica and M. insignis ; 

 he says (Carabidae, p. 168), that in Northern Europe and Siberia 

 M. aretica has received the name of erythropus Mots. ; crossing to Alaska 

 it becomes Americana Mann., and finally reaches Newfomiflland under 

 the name Hardyi Chaud. ; it is, however, all one species varying in size 

 and brilliancy of surface in the several localities. The species in form 

 and general appearance resemble a large Dyschirius, and seem therefore 

 naturally to follow this genus : it must be remembered, however, that 

 they differ very widely in many respects, and that it is not because of 

 the similarity of outward form that they are placed after them. 



TH. aretica, Payk. {Leiochiton Readii, Curtis). Usually brassy, 

 sometimes greenish black or black ; antennae and palpi red ; thorax 

 globose, very convex, with a rather indistinct dorsal line, base without 

 f oveae at sides, with a narrow depressed neck ; elytra ovate with shoulders 

 rounded, with a few more or less obsolete punctured striae near suture 

 which vanish at sides and apex ; hind body pedunculate, scutellum 

 situated in peduncle ; legs red. L. 6 mm. 



Local, usually on high moors and mountains, under stones, &c. ; Derbyshire ; York- 

 shire ; Llangollen, Moel-y-Gamblin ; Church Stretton ; Cannock Chase (taken in 

 numbers by Mr. Blatch). Scotland, local, mountains and high moors, Tweed, Tay, 

 Dec, Clyde. 



This species bears a remarkal^le resemblance to the continental species 

 Bruscosoma haldense, Putz. 



BROSCUS, Panzer. 

 This genus comprises about a dozen species which are rather widely
