124 THE ENTOMOLOGIST. 



the metasternum hardly depressed and smooth, and the spur 

 of the anterior tibiae obtuse ; in punclato-sulcatus the meta- 

 sternum is abruptly depressed, but still smooth, while in 

 pubescens it is hairy ; the tibial spur being acuminate in 

 both cases. 



Rhyssemus. — Nothing appears to me more likely than that 

 our coast species of this group have yet to be increased, 

 especially towards the South-West of England. Two or three 

 are recorded from Cornwall, though as yet on questionable 

 evidence. They are to be obtained at the roots of grass, &c., 

 on the sand-hills, 



Anomala Donovani, — The specimens preserved in the 

 British Museum are simply a North-American species, A. bi- 

 notata, Burm., as Mr. Smith pointed out to me on a recent 

 visit. As these are alluded to as types by Stephens, the 

 species will probably sink, but it was described on specimens 

 from Donovan's collection. 



Cryptohypnus maritimus. Curt. — C. scotus, Cand., is only 

 this species. Candeze appears to have re-described it on a 

 type sent him by Wollaston. 



C. dermestoides. — The commoner species in this country 

 is the 4-guttatus, Lap., from which the dermestoides may be 

 known by its immaculate elytra and dark base to the antennae. 

 It is a little doubtful whether they be specifically distinct, 

 but the balance of opinion is certainly in favour of it. 



Cardiophorus thoracicus. — It seems doubtful whether this 

 species is really British, yet Fabricius described it from a 

 British example in the first place. Mr. WoUaston's spe- 

 cimens from Cambridge were all Megapenthes sanguiuicollis. 



Melanotus niger. — If the name niger be retained for the 

 Athous, it cannot be kept here also ; hence the next earliest 

 name must be used, wiiich happens to be one given by a 

 countryman of our own in the ' Zoological Journal.' 



Ctenonychus. — This generic name of Stephens's is revived, 

 as Synaptus is preoccupied in another branch. 



Microcara Bohemanni, Mannh. — This species differs from 

 M. livida by its smaller size, less evident costae on the elytra, 

 and the raised margins of the thorax. 1 cannot, however, 

 help thinking that it will eventually be found to be a mere 

 state of M. livida. Hitherto I have found it much rarer than 

 the type.
