246 THE CANADIAN ENTOMOLOGIST. 



wliite. Expanse 0.15 to 0.18 inch. This species is closely allied to Z. 

 desjnodiella Clem., but Mr. Chambers notes the points of difference as 

 follows : " There is a shade of difference in the ground color, face not 

 white as in desmodiella, though with a silvery or opalescent lustre ; the 

 dark margms of the fasciae and streaks are less distinct ; it has no distinct 

 dorsal mark opposite the costal one before the ciliae, and the apical part 

 of the wing is not darker than the remainder ; it is also a little larger than 

 desmodiella^ 



The larva belongs to the cylindrical group, is of a whitish green color, 

 and attains a length of about 0.14 inch. It mines the leaves of the Wild 

 Bean (Phaseolus paiiciflorus). Its chief peculiarity is found in its gre- 

 garious habit, from five to fifteen imagines sometimes emerging from the 

 large tenriform mine. The parent moth places her eggs here and there 

 upon the under surface of the leaf, upon which the work of the young 

 miners is soon apparent in the form of numerous minute blisters, which 

 as they are enlarged, become confluent, and the congregated larvae soon 

 devour every particle of the green tissue of the leaf, which puffs out into 

 a cylinder. When mature the larvae construct in common a loose ham- 

 mock-like web, within which they change to slender honey-yellow pupae. 

 The imagines of the midsummer brood appear in twelve or fourteen days 

 from the change to pupae. The second brood hibernates in the pupa state. 



MR. SCUDDER'S '' BUTTERFLIES." 



BY S. H. PEABODY, CHAMPAIGN, ILL. 



This long promised and lately issued book wants little that the skill of 

 artizan or the genius of artist can furnish. The Entomological brother- 

 hood — those lovers of the net and flask, who, gentler than the historic 

 angler, impale not even a worm until it has become insensible to pain — 

 they and the general public will find some store of delightful reading 

 within its pages. W'^hether, as has been more than hinted, there are 

 notable omissions of valuable matter observed and reported, and bearing 

 with force upon topics treated therein, or not, there is enough of what Mr. 

 Scudder has himself seen, to make the volume a valuable addition to the 

 literature of Psyche.
