40 THE CANADIAN ENTOMOLOGIST. 



Chateauguay Basin, also has a very beautiful specimen of this moth. 

 These three are, I believe, the only specimens in collections.

ENEMIES OF PIERIS MENAPIA. 



Dear Sir : The determination of the Hemiptera collected in Wash- 

 ington Territory permits me to give the following notice. Podiscus 

 crocatus Uhler (MS.) is a very eager enemy of the pupa and the caterpillar 

 before pupating, when it is very sluggish. The P. crocatus was every- 

 where common in the devastated forests, and observed in the act of 

 sucking caterpillars. Neides muticus Say was seen near Loone Lake on 

 the freshly laid eggs ; one specimen, together with the eggs, is before me.

BOOK NOTICES. 



The Geological and Natural History Survey of Canada. — The 

 last volume issued by the Department is full of interest, and betokens 

 much care and skill in its preparation. The maps are excellent. A new 

 feature is a separate Catalogue of Canadian Plants, by Prof. John 

 Macoun, the well-known Naturalist of the Survey. Part I. — Polypetalae — 

 is the first of this proposed publication, and it will be a source of great 

 gratification to all our Naturalists to know that a commencement has been 

 made in this desirable undertaking. We learn from Dr. Selwyn, the 

 Director of the Survey, that "it is intended to enumerate systematically 

 the plants of the Dominion of Canada, and to define their range in so far 

 as the knowledge at present available enables this to be done. This, the 

 first part of the Catalogue, will be followed by others as it is possible to 

 complete the necessary examination of collections and authorities. We 

 venture to express the hope that in due time the "Fauna" of the 

 Dominion may be catalogued in a similar manner, and that the Natural 

 History Survey will be carried on with energy and skill in all its branches. 

 The Canadian Record of Natural History and Geology. — 

 This magazine is published by the Natural History Society of Montreal, 

 and takes the place of the Canadian Naturalist, formerly published by 

 the Society. The Record will be published quarterly. — E. B. R.
