At Cumberland, Maryland, August 9, 1903, it was not 

 abundant, but such specimens as were seen were still green, 

 the larvae only half-grown. 



Four galls taken at Sparrow's Point, Maryland, in December, 

 1903, and kept in confinement yielded parasites and adult 

 cynipids at Paris, Texas, March 18 to April i, 1904. 



8. Diastrophus cuscutaeformis. (Hym.). 



This blackberry gall was found May 5, 1903, at Blacksburg, 

 Virginia, along the side of a low mountain spur. From sixty 

 larval cases only four contained a pupa of the cynipid, four a 

 chalcidoid pupa, while the rest were empty. 



9. Sphecodina abbotii Swainson. (Lepid.). 



A male larva of this species was taken from cultivated grape at 

 Blacksburg, Virginia, June 30, 1902. It pupated on July 3. 



10. Number of Chalcidoid Parasites from a Noctuid Pupa. (Hym.). 



Four hundred and twenty-one pteromalids were reared from an 

 unknown noctuid pupa at Blacksburg, Virginia, May, 1903. This is 

 not a large number. 



11. Trypeta solidaginis. (Dipt.). 



On February n, 1905, a gall of this species was taken from golden- 

 rod at Arlington, Virginia ; the contained larva was full grown and 

 pupated five days later, emerging on March 18 following. The galls 

 also occur at Arundel, Maryland. 



12. The Length of Life of Thysanura (Entomobryidae) in 



Confinement. 



On November 9, 1902, I captured many specimens of a 

 thysanuran from beneath the very moist bark of an oak. They 

 were placed into a narrow vial, in the bottom of which was a 

 little damp soil covered by moss. A stopper of damp cotton 

 prevented escape. After the moisture in the earth had evap- 

 orated the insects clustered about the damp cotton plug. All 

 remained alive up to December 9, but by the i6th of that 

 month the plug was allowed to dry and death rapidly ensued, 

 all dying by the I9th.
