second which was captured flying in the Isle of Dogs : it may not 

 be strictly indigenous. 



Sp. 13. fasciatum. Elongatum,fusco-brunneum, antennis pedibusque pallidioribus, 



elytris fascid medio obsoletd. (Long. corp. 709 lin.) 

 Cer. fasciatus. Wilkins Catalogue. 

 TAongaite, fuscous-brown, finely punctate throughout : head with a short furrow 



on the front: thorax elongate^ with the sides dilated : elytra with a faint pale 



fascia a little behind the middle : legs and antennae pale rufo-fuscous or 



brown. 



I possess several specimens of this remarkable species, which 

 were taken twenty years since in Norwich; whether it be truly 

 indigenous I feel doubtful. 



Genus CCCLXXIX. — Obrium, Megerle. 



Palpi unequal, terminal joint elongate, of the maxillary subfusiform-truncate, 

 of the labial ovate- truncate. Antennae pilose, slender, first joint robust, second 

 subglobose, third and fourth slender, of nearly equal length, fifth elongate, 

 sixth and following shorter, and of nearly equal length with each other : head 

 broad, trigonal : eyes lunate : thorax longer than broad, with the sides pro- 

 duced in the middle : body elongate, subcyhndric : elytra rounded at the apex : 

 femora abruptly clavate : tibiw slender, simple. 



The pretty little genus Obrium, which perhaps is still capable of 

 division, evidently forms the transition from Callidium to Molor- 

 chus, having the elongate slender body and antennae of that genus, 

 with their peculiar clavated femora, but differing, amongst other 

 particulars, in having the elytra nearly as long as the abdomen : — 

 from Callidium it differs by the form of the terminal joint of the 

 palpi, and by the structure of the antennee, of which the fifth joint 

 is longest. 



Sp. 1. minutum. Rufo-fuscum, antennis testaceis lo7igitudine corporis, oculis 

 nigris. (Long. corp. 2| — 3 lin.) 



Sa. minuta. Fabricius.~Ce. minutus. Donovan, xvi. pi. 553. f. 2.— Ob. mi- 

 nutum. Steph. Catal. 199. No. 2035. 



Rufous-Aroww, with the eyes black : antenna as long as the body, testaceous : 

 legs pale rufous-brown, with the femora clavate : elytra with an angular 

 elevation in the middle : thorax elongate, with the lateral margins dilated : 

 abdomen beneath shining black. 



In the female the antennse are slender, and the thorax less elongate.
