NOTICE ON THE GALLS COLLECTED BY LIEUT. W. L. CARPENTER. 



By C. E. OsTEN Sackex. 



A. — Oak- GALLS, Colorado Springs, September 25. 



1. Leaf-gall, globular, hollow, very similar to the gall of Cynips singu- 

 laris, Bassett, although not identical. The gall-fly, a Oynips, was cut out 

 of the gall inside of which it had died before being hatched. 



2. Leaf-gall of the same class as that of Gynips pegoinachoides, O. S., 

 and Gynips erinaceus, Walsh. 



3. Bud-gall, different from all other galls known to me in this coun- 

 try ; probably likewise a Gynips. 



It is to be regretted that the species of oak on which these galls were 

 found were not taken note of. 



B. — WiLLOW-GrALLS. 



All the galls examined, from four different localities, belonged to a 

 hymenopterous insect, Nematus (family Tenthredinidce), very common 

 on willows. 



The galls taken July 7 were very young ; those taken on East Eiver, 

 August 12, still contained the caterpillar; those of September 1 to 18 

 were empty. A lot taken near the Twin Lakes, July 29, had a peculiar 

 shape, and was covered with a whitish bloom. It may have been a 

 different species, although it is undoubtedly a Nematus. 



C. — Cottonwood galls. 



September 18, Clear Creek ; galls formed by Aphides at the point of 

 attachment of the leaf-stalk to the leaf. They are very similar to the 

 galls of Pemphigus popuUcaulis, Fitch, on poplar, and may be produced 

 by this very species. 



July 15, South Park ; woody swelling of the branches. It does not 

 seem to be a gall, as it is entirely solid on the inside. It may have har- 

 bored insects, .as several round holes upon its surface seem to indicate, 

 but the deformation is not necessarily caused by the presence of these 

 insects. 



D. — Galls on sage-bushes. 



September 8, pupa-shells, found inside of these galls, seem to belong 

 to the genus Trypeta.
