Editorial. 



In the December issue (Vol. xii, p. 254) the figure labelled to 

 represent Caddo glaucopis should be transferred to C. boopis, as Mr. 

 Crosby has informed us. 



Contributors to the Journal will please take notice that they can 

 have separates of their articles printed in any number and in any form 

 at cost, by notifying the editor sufficiently in advance. The publica- 

 tion committee has found it necessary to discontinue the sending out 

 of reprints free of other matter, as was done with volume xii. Au- 

 thors who do not notify otherwise, "shall be entitled to 25 copies" 

 and will usually receive 50, without change of form, which means 

 that there will generally be some foreign matter at the ends. 



The scope of P. Wytsman's " Genera Insectorum " is, in the por-

 doptera Phalaenae, ' ' but the treatment of species is far less complete 

 and satisfactory. It includes the butterflies, as Hampson does not. 

 If the subject were to be pushed energetically, it would result in a 

 practical duplication of Hampson's work, which we think would be a 

 waste of effort. An advantage would accrue to the student if the 

 families to be first treated were those which Hampson will reach last, 

 and at the present rate of publication, not reach for many years, 

 namely, the Tineoid groups. However, there has been no evidence 

 till lately of any intention to push the subject energetically. We 

 have had before us some small fasicules in which several authors have 

 treated of sundry of the smallest groups they could find ; the Liby-
