154# Callirhytis excavata (Ashm.). X 1. 425. On Q. imbricari a. Also on Q. rubra 
(type host), velutina . ilicifolia . From galls picked up on ground in Oct. 
1944 a living adult was found in the cage Jan.1,1946. Normal emergence 
date unknown. A bit of cloth tied about the twig will prevent the 
galls from being lost when they mature and drop. Fig.282- shows the 
individual gall X 5. 
155. Callirhytis gemmaria (Ashm.)..X 1. 4^6. On Q. oinerea . On all the red oaks. 
Galls secrete honeydew, drop whhn mature. Rearing record needed. 
Gates observed galls on Wayah Bald, N.Car. in 1957* Galls were on 
previous year's growth of every twig of every tree affected over an 
area of 600 acres, on red oak, none affected below 5100 feet. From 20 
-2oOO galls on one twig. Most mature by early July. Start dropping by 
the middle of August. If the twig is girdled by the galls the new 
growth dies and turns brown and the extent of the infestation is visible 
from a distance because of the color. Trees were 70“75% defoliated. 
No galls were found in 1958 or in 1959. In 1940 there was a heavy in¬ 
festation again, the area larger and the line of demarcation not so sharp. 
This will kill the trees and create a bald he thinks. 
156. Callirhytis gemmaria (Ashm.). X 1. 4^6. On Q. rubr a. When attacked by guests 
the galls do hot drop, enlarge, become woody and remain on tree over the 
winter. These were once described as an Andricus but the types were 
all Synergus. These woody galls often bear traces of the truncate end 
and ribbed surface of the original gall. 
157. Never reared. X 5. On Q.t exana . Drops to ground in Oct. Boerne,Texas• 
158. Disholcaspis sp. X 1. On Q. lacey i. On top of sprouts from stump. Contained 
adults on Nov.20. Boerne,Tex. Never described. 
159# Disholcaspis sp. X 1. On Q. margaretta . Also on Q. atellata . Contained pupae 
Sept.15. Adults were cut out Nov.15* Living adults were in breeding 
cage on Mar.l. Galls are harder, occur in larger groups and have a 
rougher surface than the bullet gall on white oak, Disholcaspis quercu s- 
g lobulus (Fitch) of which it has been made a synonym in literature. 
Bassett described it from Q. prinoides under the name of rugosa . The 
life history needs to be worked out. 
160. Disholcaspis bassetti (Gill.). X 1. 557* On Q. bioolor. Also on macrocarpa . 
Contained pupae Sept.l6, adults Oct.2. 
161. Never reared. X 5. Cti Q. imbricaria . On vigorous sprouts from stump in Oct. 
Found only once in Mo. and once in D.C. 
Disholcaspis quercus-globulus (Fitch). 548. On Q. alba . Round Bullet Gall. 
Smooth, about 8 mm., corky, single or few in a cluster on small twigs 
in fall. Contain pupae Sept.25 and adults emerged 0ct.20-Nov.l (Chi). 
Brodie says they emerged 0ct.l2-Npv.l at Toronto and oviposited at 
once in white oak twigs. 
Disholcaspis succinipes (Ashm.) • 550. On Q. virginiana . Cluster of 5-20 
globular galls, 5~8 mm. in dia., with a buckski,n surface. Described 
from one adult (Fla.). Gall not recognized in the field. 
Disholcaspis fungiformis Kinsey. 540. On Q. virginiana , in Texas. Fig.298. 
A two-story gall in a cluster. The types were cut out of galls 
collected 55 years previously. 
Andricus indistinctus Bass. 5^4. On Q. alba . The type gall in Philadelphia 
is globular, slightly wrinkled, dark colored, 4 mm. in dia.. Adult 
was nearly mature in Oct. The type and the two others belong in the 
genus Disholcaspis (unpublished).
