THE CANADIAN ENTOMOLOGIST. 321 



It will be remembered that Prof. French named this species from a 

 larva, great quantities of which were found in the evacuations of a child 

 subject to periodic epileptic spasms. As these attacks ceased for a time 

 after the use of purging medicines, by means of which large numbers of 

 the maggots were voided, Prof. French appears to have assumed, 

 curiously enough, that the spasms were caused by the reprodtictio?i of the 

 larvce in the intestines (the italics are mine) and the effect of the same on 

 the nervous tissue ; hence he gave the maggot the specific name 

 epilepsalis. 



In sending the above cutaneous larvaj found by Dr. Foster to 

 VVashington, I gave no data whatever, and yet they were declared 

 identical with Prof. French's type, an intestinal parasite. 



It is a pity no imagoes were reared from the larvee. It appears 

 probable that the species is badly named, for it evidently has no 

 connection with epilepsy. In any event, much remains to be learned 

 regarding it. 



BOOK NOTICE. 



Check List of the Lepidoptera of Boreal America. — By John B. 



Smith, Sc. D., Professor of Entomology, Rutgers College, assisted by 



Henry Skinner, M.D., and W. D. Kearfoot (Kearfott), Philadelphia. 



American Entomological Society, June, 1903. 



Prof. Smith has produced a new edition of his List of 1891, brought 



up to date. There seems a certain savour of rivalry in the appearance of 



this publication immediately after the Washington catalogue (Bull. 52, U. 



S. N. M.), especially as the Edwardsian names for the butterflies are 



again advanced. Still, there may be some excuse for the List in its 



smaller size and more compact form. The absence of a specific index is 



a great disadvantage. As a whole, the Washington catalogue has been 



copied, with a new set of numbers. There are some divergences, on 



which comment may be made. The most marked is Dr. Skinner's 



restoration of the Edwardsian names for the butterflies. I am sure this is 



a false position. As I have repeatedly said, there are probably too many 



genera in Dr. Scudder's system, but they must be fully studied. Prof. 



Grote has shown how it should be done in the Papilio group. A 



wholesale rejection of Dr. Scudder's work is not the way to solve the 

 problem. 



In the Sphingidae Prof. Smith makes a few changes, hardly for the 

 better. All the forms of Hetnaris teiuiis are given specific rank, which
