ther up the stem, the hollowed-out channel gradually narrows, 

 widening occasionally for some older larva (we may infer 

 that first oviposition is done near the surface of the ground, 

 later the eggs placed higher up on the stems), so that half 

 way up the stem of the plant, merely the narrow, oblique chan- 

 nels of the smaller larvae are usually present at this time, none 

 of which lead directly from the nidus to the pithy center of 

 the stem but instead are more or less diagonal and curved, 

 sometimes irregular or tortuous. No pupae have been found 

 as yet. The larvae were, of course, in various stages of de- 

 velopment. 



On August 7, a badly infested plant taken from the field 

 and examined contained full-grown larvae and also pupae. 

 No adults have been noticed since the fifteenth of July. No 

 other notes were obtained. 



It is easily inferred that but a single generation of this wee- 

 vil occurs during a season, the adults emerging in the late 

 summer and early autumn and without attempting reproduc- 

 tion, hibernate. The next spring, they feed and mate, then con- 

 tinue to lay eggs for about two months, and in course of about 

 a month and a half after the first eggs the adults may com- 

 mence to emerge, continuing for a month or so. At Butler. 

 Ill, eggs were found on July i6, 1910. Larvae, then, were in 

 all stages of development. Mr. E. A. Schwarz, U. S. N. M., 

 kindly authoritatively identified the specimens. 



A Note on Chlamys plicata Fabricius. — This peculiar chrysomelid 

 was abundant on wild blackberry plants at Centralia, 111., during 1909. 

 These notes were made concerning it : Larvae present during June ; 

 first pupa found in the larval case attached to the stem of a weed, two 

 feet up from the ground, on June 28. The first beetle emerged from 

 pupae kept in confinement but collected outdoors, on July 7 to 9. On 

 July 19, 1909, 10 beetles which emerged a week and a half earlier were 

 transferred to a breeding-cage containing fresh foliage of blackberry: 

 although they lived for at least a month, they did not reproduce. They 

 had been well attended to as regards food. — A. A. Gir.\ult, Urbana.
