Kinsey: Studies of Cynipidie 



95 



TYPES. — Adults and galls, in the U.S. National Museum; labelled 

 3064. 



The redescription of adults and galls is made from a con- 

 siderable quantity of material in my collection, compared with 

 types. 



The insects from Auburn and Dunsmuir material agree 

 entirely with those from Placerville. I collected galls from 

 March 26 to April 3 ; the adults emerged at some later date. 



Heteroeciis pacificus variety subpacificus, new variety 

 Cynipide, 38, Trotter, 1910, Boll. Lab. Portici, V, p. 114, pi. 1, figs. 22-23. 



FEMALE. — Differs from the female of the other varieties of the 

 species only as follows: Parapsidal grooves rugose at bottom; median 

 groove short or lacking; wing veins somewhat finer than in variety 

 pacificus; areolet of only moderate size, about equilateral; first abscissa 

 of the radius more arcuate than in either other variety; length 3.0-3.2 

 mm., distinctly smaller than in variety pacificus. 



GALL. — Very similar to the galls of other varieties of the species, 

 difi'ering in averaging much shorter, but of as great diameter as in 

 variety pacificus, hence more robust; the tip is about as long as in 

 pacificus, often curved, even at right angles with the body of the gall. 



RANGE.— California: Yosemite (Trotter); El Portal, San Jacinto 

 Mountains. Probably thruout the southern Sierras and their extensions, 

 from El Portal south, except in the San Bernardino and Cuyamaca 

 ranges. 



TYPES. — 5 females, 40 galls. Holotype female and paratype galls 

 at The American Museum of Natural History; paratype adults and galls 

 at Stanford University, the U.S. National Museum, and with the author. 

 Labelled El Portal, California; March 26, 1920; Kinsey collector. 



The insects had mostly emerged in the San Jacinto moun- 

 tains by February 28. Further north at El Portal a larger 

 proportion of the insects had not yet emerged on March 26. 

 Thus do emergence dates vary with the development of the 

 season. 



This variety comes very close to variety pacificus, but does 

 show differences in the insect morphology, the galls, and the 

 range. San Jacinto material agrees distinctly with the El 

 Portal material ; altho the two localities are about three hun- 

 dred and fifty miles apart they are in the same faunal area. 



Hetercecus pacificus variety gracilis, new vaiiety 



FEMALE. — Differs from other varieties of the species as follows: 

 Generally of a darker, licher rufous brown; parapsidal grooves almost 

 entirely smooth at bottom; median groove often longer, very wide at
