sometimes found in moss. Beyond the superficial differ- 

 ences of colour (and wbicli are, indeed, themselves only com- 

 parative), I must confess an inability to see any points of 

 discrepancy between this insect and the ordinary type of 

 troglodytes. 



'^b. Ceuthorhynchideus frontalis, Ch. Brisout, MS. 



Mr. Crotch (Joe, cit.) also informs us of M. Brisout's 

 intention to describe under this name the insect hitherto con- 

 sidered a small form of trofjlodytes. It has, I believe, long 

 been separated from that species in Mr. S. Stephens' Col- 

 lection ; and appears to be rare. Mr. Waterhouse and his 

 sons took some few specimens (with me) at Scaford during 

 the last autumn. They were at the roots of a small plan- 

 tain. 



The insect very closely resembles C. tror/lodyteSf but is 

 much smaller ; and appears to have invariably a patch of 

 white scales between the eyes. 



86. Ceuthorhyxchideus Dawsoxi, Ch. Brisout, MS. 



Mr. Crotch (loc. cif.) remarks that M. Brisout, having 

 received from Mr. Dawson the insect known to us as 

 pygmcpus, Guyon, in litt., intends to describe it under the 

 above name. It would, doubtless, have been in better taste 

 if the name under vrhich it was received, and by which it 

 has so long been known to us, were retained by M. Brisout; 

 but, after having neglected the opportunity of describing the 

 insect for so many years, British Entomologists have lost 

 tlie right to object on this score. 



This, of all the troglodytoid forms, appears to be the 

 most worthy of specific elevation ; on account of its exceed- 

 ingly small size, more ovate and continuous outline, com-
