 it may be a color phase of it. 



Dysphaga tenuipcs Hald. 



Brief Notes; Record of a Parasite. 



By a. Arsene Girault. 



A small branch ( ^ inch diameter) of a species of oak on 

 the campus of the Virginia Polytechnic Institute at Blacks- 

 burg, Va., was found infested with several species of wood- 

 boring Coleoptera, which when bred, proved to be the following 

 species* : Stephanoderes quercus Hopk, MS.; Micrasis opacicollis 

 Lee; Aiithribus cornuius Say ; Dysphaga tenuipes Hald. f 



The bare and dead branch, and the conspicuous, fine, impal- 

 pable, flour-like, wood-dust on the leaves and ground below 

 the branch were the indications of attack. But a single 

 branch was found infested ; this was cut into convenient 

 lengths, and put in a glass jar covered with cheese cloth, and 

 filled with moist earth. This jar was kept in the laboratory, 

 and on the following dates adults of Dysphaga tetiuipcs were 

 excluded: 21, 24 Nov., 1902; 11, 14, 17, 19, 23, 28 Febru- 

 ary, 1903, those appearing on the latter date (28 February), 

 excluded in the green-house, 14 specimens were obtained, 

 ^'s, 9 's. 



After remaining in the laboratory from 5 September, 1902, 

 until 25 February, 1903, they were removed to a green-house, 

 where the temperature ranged from 90-100° Fahr. , during the 

 day. Here they were supplied with fresh twigs ; and here 

 they had plenty of sun-light (got very little, if any, before), 

 and soon became active, flying along the sides of the jar as do 

 moths, making quite a distinct buzzing sound, and resembling 

 small Sesiids on the wing. 



After this, a supposed attempt at copulation was observed, 

 but beyond that, no signs of continued breeding were ever
