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 §, 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. 
sae Trypeta solidaginis. (Dipt.). 
On February 11, 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 16th of that 
month the plug was allowed to dry and death rapidly ensued, 
all dying by the roth.
