brown, the lower white. Along the back is a chainlike series of angular 

 brown lines forming diamond-shaped divisions. In the hinder angle of 

 each division is a conspicuous white spot. The larva lies hid during the 

 day. and comes out and feeds at night. When disturbed it curls up into 

 a bunch. Moulted September 21st.

 a few white hairs. Body colour of larva above rich warm green, with 

 brown markings and a dorsal line of white spots. Spiracular line creamy- 

 white. Under side of larva pale green with reddish-brown spots. The

The Pterophorid.« of North America. — By C. H. Fernald, A.M., Ph.

Any one who has a copy of Prof. Fernald's Manual of the Crambid?? 

 of North America will hardly need to be told that this later work is 

 exactly what every student or collector of the micro-Lepidoptera wants, 

 and that the way is now made easy for him when he wishes to identify 

 his plume-moths and learn all that is thus far known about the North 

 American species. It is characterized by its author's well-known accu- 

 racy and conciseness of statement, and is a complete monograph of the 

 family as far as this continent is concerned. It begins with an historical 

 account of the family in the writings of European entomologists and the 

 more recent publications in America. This is followed by short chapters 

 on the structure, habits, early stages and systematic position of the plume- 

 moths. The body of the work is taken up with descriptions of the genera 

 and species, including very useful synopses in each case. Three of the 

 plates illustrate the external anatomy and the structure of the wings, the 

 remainder depict the genitalia of the species. We miss, however, the 

 exquisite coloured plates that so beautifully illustrated the Crambids. 

 We need not say more than that this is a full and entirely satisfactory 

 work on the Pterophoridee, and that it maintains the high standard of 

 excellence that we now expect in the author's scientific productions.
