species, Pterophorus monodactylus Linn., was found in several localities in 

 California and Oregon. Two varieties are figured. This species is 

 identical with P. pergracilidactyhis Pack, and -P. cinereidactylus Fitch. I 

 have it from New England and Illinois, as well as from California. My 

 specimens from California show even more extreme limits of variation 

 than the European forms, of which I have received a set through the 

 kindness of Prof. Zeller. Dr. Packard's sulphureodactylus is re-described 

 and christened sulphitreus, in accordance with the laws of nomenclature. 

 Prof. Zeller is cited, who has taken the same liberty with Prof. Riley's 

 hybrid name carduidadylus, reducing it to the unobjectionable cardui. As 

 to the propriety of thus changing original names, I at present express no 

 opinion. Much might be said both for and against. It is certainly desir- 

 able in naming a new species to conform strictly to the rules of zoological 

 nomenclature, both that the names may be harmonious, and that we may 

 not at some future time find our names degraded to the rank of synonyms. 

 Lord Walsingham has very generously given types of most of his 

 described species to Prof. C. H. Fernald, of the Agricultural College, 

 Orono, Maine, where they will be accessible to Entomologists engaged in 

 the study of this group of insects on this side of the Atlantic. I would 

 add that this little book of Lord Walsingham's is the first work containing 

 anything like a full representation of the Pterophoridse of any section of 

 North America, and I commend it to the consideration of all who are 

 interested in the study of the beautiful forms of this difficult and hitherto 

 much neglected family of the Lepidoptera. 



NOTES ON CATOCALA HUNTING. 



BY. G. H. FRENCH, CARBONALE, ILL. 



A few of the members of my zoology class and myself have taken here 

 821 specimens of Catocala? in nine consecutive days, collecting from 

 August 1 6th to August 26th inclusive, omitting Saturday and Sunday, dur- 

 ing which no collecting was done. These were all taken in the afternoons, 

 usually from one to four o'clock, by whipping the trees, and all within
