LIST OF COLEOPTERA. 87 



I know from my own personal experience that it is so, but this does not at 

 all militate against my double-brooded theory. All I say is this, 2V. dictcea, 

 Dictceoides, Dromedarius, and Camelina lay eggs in May, or the first week 

 in June, which hatch and produce perfect insects in August; and these latter 

 are fertile. In the case of Dictcea, they have been seen to pair and lay 

 eggs, which have again produced full-fed larvae in the autumn, and this has 

 taken place out of doors as well as in. I also say that, as far as my own 

 personal experience goes, confinement has little or nothing to do with this 

 so-called abnormal state of things. Finally, after carefully weighing the pros 

 and cons, I can come to no other conclusion than this, that both Camelina 

 and Dictcea, Ziczac, Dromedarius, and Dictceoides, are naturally double-brooded. 

 I will give my reasons for including the three last-named, when I come to 

 them. When I wrote my papers on this subject, in the "Zoologist" for 1856, 

 my assertions were made entirely on my own experience; since then Mr. 

 Harding, of Stapleton; Mr. Naish, of Bristol; and Mr. Gaseoyne, of Newark, 

 have devoted themselves to the investigation of the subject, and it is peculiarly 

 gratifying to me, to find all my assertions so fully corroborated and confirmed 

 by the results which have crowned their efforts. It was only the other day 

 that my friend, Mr. Bree, lent me M. Guenee's and Duponchel's work, to 

 which I have previously referred, and there too I found, to my no small 

 delight, all my assertions confirmed. With such an authority to back me, I 

 feel as if I could face all my opponents, even though their name be Legion. (C.)
