NEW BRITISH SPECIES, ETC., IN 1866. 49 



avoidance of anything like tangible characters ; and it was 

 with considerable hesitation, and preferring a possibly erro- 

 neous British record to the risk of increasing specific 

 synonomy, that I brought forward the insect as I did. My 

 specimen (given to me by Mr. Bold) certainly seems inca- 

 pable of separation from an example of P. addendus given 

 to me by Mr. Sharp ; but, at the same time, a long and 

 careful examination, both by that gentleman and myself, 

 failed to separate the former specimen satisfactorily from 

 another belonging to him, and named tempo7'alis by a con- 

 tinental authority. 



My own impression is entirely in accord with Mr. 

 Sharp's, viz., that there are certain species of the cFneus 

 gi'oup {carbonariuSf Gyll., temporalis, Muls., tenuicorniSy 

 Muls. and punctiventris, Ktz.) which are in a state of con- 

 fusion, and some of which are not unlikely to be suppressed 

 eventually. It is to be hoped that Mr. Sharp's insect, pos- 

 sessing — as it does— the merit of being distinguish'ably de- 

 scribed, will be lucky enough to escape that fate.

 Mr. Crotch states that this insect was sent to Dr. Kraatz 

 by its captor, Mr. Janson, under the MS. name " Mardiiy' 

 and that it was returned as new. 



It appears to be very close to L. paUidum, but to differ 

 from that species in its darker colour and stronger punctua- 

 tion, and by its elytra being scarcely shorter than its thorax.
