308 Forty-second Report on the State Museum. [166] 



Oak Galls. (Country Gentleman, for October 18, 1888, liii, p. 775, c. 



2 — 7 cm.) 



Small, round, pubescent galls, sometimes single, oftener confluent 

 on oak leaves {Qiiercus sp. ?) from Kingston, E. I., are identified as those 

 of Neuroterus verrucarximO. S. — one of the Cynipidce. No means are 

 known by which these galls can be prevented. Their multiplication can 

 be arrested by picking off and burning the leaves containing them, when 

 not involving too much labor. 



The Cow-Fly or Texas Fly. (Country Gentleman, for October 18, 1888, 

 liii, p. 779, c. 2 — 7 cm.) 



The fly is stated by Dr. Williston to be a species of Stomoxys, apparently 

 undescribed and which he purposes to name S. cornicola [erroneously 

 given as cervicola]. Now that it is Icnown to be allied to Stomoxys cal- 

 citrans — a biting species with which we have been long familiar, the 

 many stories of the serious and sometimes fatal injuries to cattle of this 

 new insect, are effectually disproved. 



Caterpillar on the Chestnut. (Country Gentleman, for October 18, 

 1888, liii, p. 786, c. 2 — 12 cm.) 



Caterpillars sent from Eochester, N. Y., from a Spanish chestnut tree, 

 are Halesidota tessellaris (Sm.-Abb.). The general appearance of the 

 moth is given. The caterpillar feeds on several of the forest trees and is 

 common on the sycamore. It has not been recorded from the chestnut.
