 Syst. Eleut. i. 251. — Loudon, Mag. Hist. Nat. v. 86 and 556. — In the places 

 above quoted of Loudon is a complex account of the erroneous admission of 

 this North American insect in Curtis's Guide: I therefore merely refer 

 thereto by way of remarking that that insect has never been taken in 

 England ; neither is it likely.

Palpi short ; the terminal joint large, obtusely conic, the penultimate small, 

 obconic, the antepenultimate rather larger and conic. Antennce also short, 

 the basal joint long and curved, incrassated at the apex ; the second joint 

 large, globose, with a rigid bristle on one side; two following minute, 

 also setose, the next transverse, the remainder forming an elongate-ovate, 

 obtuse, pilose club, the central joint of which is longest : in other respects 

 similar to Hydrobius.

 appears to be the only specimen of the genus : it occurs not very commonly 

 in damp places, imder moss, &c. 



Page 136. Genus CERCYON. I appear to possess several new species of 

 this troublesome genus, though I shall refrain from describing any but the 

 one introduced into the second edition of my Nomenclature, in order to 

 allow of a more mature examination than I have the means of giving 

 thereto.

Pitchy-red, glossy, and faintly punctured ; elytra obscurely pimctate-striate, 

 paler than the thorax, and with a round brown cloud in the centre of 

 each ; legs and antennae pale pitchy-red. 



Found near London.

Palpi exserted, the terminal joint thick and obtuse. Aritenna; nearly as long 

 as the thorax, the basal joint large, oblong-ovate, swollen without, the 

 second shorter, somewhat rounded ; third to the eighth small, nearly equal, 

 the remaining three forming a large obovate, villose club, of which the two
