210 THE CANADIAN ENTOMOLOGIST. 



fluously and in an exaggerated manner drawn attention to my mistake on 

 different occasions, but if he would devote the time to looking up already 

 described species before re-naming them and familiarize himself a little 

 more with structure, his descriptions would have a value which they do 

 not yet possess, and his time be better employed. I need not say that at 

 the time I published these species there was comparatively little known 

 on the subject and information was not so easily obtained as at present. 

 A mistake like that made by myself, once corrected, has no further value 

 in science, and in Mr: Strecker's hands is only used as an excuse for an 

 unwarrantable personal attack. 



Dr. Packard omitted the genus Nemeophila from his Synopsis of the 

 Bombycidae. It is not yet found in the Eastern States, but in the West 

 and North. As collections come in it seems probable that we have but a 

 single variable American form, but whether this is identical with the Euro- 

 pean cannot as yet be considered certain. The occurrence of this genus 

 on the western coast increases the resemblance to the European fauna. 

 Dr. Packard says regarding a species unknown to me : " Platarctia Scud- 

 derii Pack., as I have long suspected, is a Nemeophila and closely allied 

 to N. pctrosa, the anal claspers of the male being much like those of the 

 latter " (1. c. p. 86). It may, then, turn out that the Californian forms 

 are distinct from the North-western and that different species of these 

 latter (petrosa and Scudderi) are to be separated. I wish here, however, 

 merely to point out that we are not in a condition to come to positive 

 conclusion as to these points as matters stand at present.
