Observations and Notes. 



Eudryas unio. — I obtained July 220I, 1880, twenty or more examples 

 of the larvae of this moth, found feeding on Oenotheria biennis grow- 

 ing in the Buffalo Park. A few were taken at the same time and 

 place upon Epilobium coloratum. By August 1st all had become 

 pupae. For two or three days before transforming they busied 

 themselves at boring the weathered pine boards of the feeding-box; 

 finally they went into the earth or beneath the leaves in the box, and 

 changed. 



August 29th, a few imagos appeared. The majority, however, 

 passed the winter as pupae, the moths appearing in June. (See Lint- 

 ner's Ent. Cont., No. III., 117.) D. S. Kellicott. 



Smerinthus modesta. — One larva was taken on Populus tremuloides, 

 September n, 18S0. The following brief description is from my 

 note-book: Length, 3.3 in.; robust, attenuated anteriorly. Color, 

 pale green, granulated over entire body with white ; the lateral 

 stripes, the first and sixth faint, the seventh, much broader and 

 brighter than any other one, it terminates in the minute, black- 

 tipped caudal horn. Head of the usual triangular form having 

 conspicuous white lateral lines. Feet roseate, spiracles of the same 

 hue. 



The larva disappeared in the earth of box, September 13th; on 

 the 19th the roof of the cell fell in, uncovering the there contracted 

 caterpillar ; on the 20th the 



PUPA 



appeared. Length, 1.95 in.; diameter, .65 in.; black, shagreened; 

 spiracles, except the first and eighth, fulvous within the rather nar- 

 rowly elliptical rings. Cremaster a rough triangular process, flattened 

 horizontally ; no spines or crochets. D. S. K. 



Hylesifiics' trifolii. — I found this clover-root borer quite abundant 

 in the roots T. pratense about Buffalo in June, 1880. At this time, 

 May, 1881, in some fields three-fourths, at least, of the roots are 

 attacked ; in some cases the clover is " run out," apparently by the 

 beetle. Mr. Riley gave an account of its habits, and proved it to be
