NEW BRITISH SPECIES, ETC., IN 1866. 45 



remarked, that we can last at the pace at which we are now 

 travelling. Mr. Crotch's Catalogue is increased by the 

 determination of species contained in the very large collec- 

 tions (Mr. Wollaston's, Mr. Janson's, &c.) acquired by 

 him ; and the list is much swelled by the result of Mr. 

 Sharp's residence in Scotland. It is probable that we may 

 still, for a limited period, add to our Catalogue, by strictly 

 examining old collections, by which course also many other 

 points will be cleared up ; but, after a time, species new to 

 us will much less frequently occur, and our attention must 

 be directed to synonymic matters. As it is, thanks mainly 

 to Mr. Crotch's exertions, we have rather more of these 

 latter than is required at the present juncture. I have en- 

 deavoured, as far as space allows, to notice all the changes 

 made, when accompanied by published reasons; but there 

 remain a large number in Mr. Crotch's Catalogue, for which 

 he gives no explanation, — and, indeed, they mostly speak for 

 themselves. I notice, particularly, that in the case of many 

 of the Stenif he (as before) deposes the Stephensian names, 

 attributing, however, the species to me, because I recently 

 described them in the Entomologist's Monthly Magazine. 

 This is very likely to induce error; and is, indeed, not 

 strictly fair. I see in De Marseul's last Catalogue (in 

 " L'Abeille") that S. debilis is attributed to me ; whereas the 

 truth is that I have been at some trouble to prove the 

 identity of Herr Dietrich's supposed species of that name 

 with Erichson's opacus. 



Mr. Crotch's Catalogue is, of course, formed upon the 

 recognised continental classification, and comprises many 

 interesting and grammatically correct changes of generic 

 and other names. It is particularly free from omissions 

 (I as yet only notice one species, Telephorus flavilahriSf 

 Fall., as absolutely forgotten) and mistakes ; and the species
