ART. 18. NOTES ON CYNIPID WASPS WELD. 15 



Tyye localit]/.— Colorado Springs, Colorado. Galls collected No- 

 vember 4, 1918, by Mr. J. H. Pollock and sent in under Hopkins 

 U. S. No. lOTTS'^. One % reared November 11, 1918, others found 

 alive in cage January 15, 1919. 



ANDRICUS CINNAMOMEUS Ashmead. 



Andricus cinnaniomeus Ashmead, Trans. Amer. Ent. Soc, vol. 14, 1887, 



p. 137. 

 Andricus calycicola Ashmead, Trans. Amer. Ent. Soc, vol. 14, 1887, p. 141. 



A. calycicola was described as producing two types of galls on Q. 

 laurifolia, one inside of buds and one in an aborted acorn cup. The 

 type fly and gall as labeled by Ashmead and agreeing with his de- 

 scription are quite obviously the same as cinnamomeus^ of which the 

 United States National Museum has nine type flies and whose bud 

 gall is produced on Q. chafinanL The writer has collected it at St. 

 Petersburg, Daytona, and Ocala, Florida, and reared the fly which 

 agrees with the types. 



The acorn gall and fly belong to CaUirhyfis. The gall is one of 

 those which develops by the side of young acorns and then drops to 

 the ground. As there is only one fly, without a head, in the collection 

 no attempt is here made to determine or describe it. 



ANDRICUS FORMOSUS (Bassett). 



Cynips formosa Bassett, Proc. Ent. Soc. Phila., vol. 3, 1864, p. G79. 

 Cynips capsuala Ashmead, Trans. Amer. Ent. Soc, vol. 12. 1885, Proc. p. 9. 



C. formosa was described from Waterbury, Connecticut, as forming 

 a very rare gall on Q. mhra. The United States National Museum 

 has a type fly and gall from Bassett. C. capsuala was described from 

 Q. cinerea and Q. cateshaei from Florida, and the museum has two 

 type flies which agree with the type material of formosa. 



The writer collected these galls on the ground at Jacksonville, 

 Florida, April 4, 1914, under Q. fhellos. When a few were opened 

 the middle of the next November, both pupae and adults were found. 

 Flies emerged in breeding cage by February 24, 1915, and more came 

 out February 15, April 15, and May 6, 1916, taking two years to 

 emerge. This gall seems to be produced on Q. laurifolia^ also in 

 Florida. The writer has found old galls under tree of Q. imbri- 

 cana at Poplar Bluff, Missouri; under Q. texana at Boeme, Texas; 

 and fresh growing clusters of galls on Q. coccinea at Miller, Indiana; 

 Fort Sheridan, Illinois ; and East Falls Church, Virginia. It seems 

 to be common in the south and rare in the north, where it occurs 

 on other host oaks.
