192 THE CANADIAN ENTOMOLOGIST. 



This part of the work is a model worthy of imitation by other systematic 

 writers. When all our insects have been studied in this careful manner 

 and then monographed, we shall have a sound basis for further work. 



A vast field is open for future investigation on the early stages of these 

 insects, and undoubtedly our economic entomologists will, in time, give 

 us much valuable information in this direction now that thii way is made 

 clear. 



The author states that he " takes little interest, comparatively, in the 

 guesses which are made of the ancestry of any group of the Lepidoptera." 

 I am greatly surprised that he should decline to enter upon this fashion- 

 able field of conjecture. A person may as well be out of tl^^e world as 

 out of fashion ! 



There are given synopses of the sub-families and of the genera, and 

 under each genus is a synopsis of the species. A valuable feature is the 

 giving of the type under each genus and the full synonomy. A list of 

 undetermined species is also given with the original descriptions. Seven 

 of these are Walker's species and the remaining three were published by 

 Clemens. It would have been a great satisfaction if Mr. Hulst had given 

 us the correct pronunciation of the generic names, especially those of 

 Indian origin, for some of us may forget our Latin so far as to pronounce 

 some of them incorrectly. 



Under Notes on other Species, p. 221, by a slip it is stated that JSie- 

 phopteryx mtractella Walk, is a synonym of Blepharomastix ranalis 

 which is itself a synonym of Botis sitnilalis Guen. As the information 

 went from me, and I may have made the slip myself in writing, I take this 

 occasion to correct and say that Nephopteryx intractella Walk, is a syn- 

 onym of NympJmla similalis Guen., and is given in Grote's Check-List 

 under the name of Eurycreon rant alls Guen. See Ent. Am., Vol. 5, p. 211. 



At the end is given a catalogue of the Phycitidae of North America, 

 comprising 71 genera and 201 species, followed by three plates of struc- 

 tural details. 



On the whole this is one of the most satisfactory papers on the micro- 

 lepidoptera I have ever seen, and it is " devoutly to be wished " that Mr. 

 Hulst will immediately take up the Geometridce and treat them in as 

 thorough and complete a manner as he has the Phycitidie.
