Kinsey: Studies of Cynipidse

others, however, vary toward nhctculipennis, and probably 

 variety provincialis is not yet wholly separated from the other 

 varieties, but there is a strong indication that a distinct type 

 has been or is being isolated in the San Bernardino range. 



Andricus pomiformis variety descansonis, new variety 



FEMALE. — Shows the following characteristics in addition to those 

 common to all varieties of the species: Parapsidal grooves apparent but 

 rugose at the bottom and largely lost in the mesothoracic sculpture; a 

 very short but rather distinct indication of a median groove at the 

 scutellum; anterior parallel lines line, smooth, more or less continuous, 

 but not as distinct as in variety pomiformis; lateral lines of moderate 

 weight, finer than in variety pomiformis, heavier than in maculij^ennis ; 

 mesopleurae with the smooth central area largely but not entirely free 

 of punctures and hairs; foveje separated by a very low rugose area, 

 bottoms of foveae somewhat rugose, at least in part; areolet very small 

 or closed; the cloud on the first abscissa of the radius very limited, 

 smaller than in any other variety. 



GALL. — Similar to the galls of all other varieties except distinctus; 

 smooth. On Quercus agrifolia. 



RANGE : California. Descanso, Probably confined to a higher 

 elevation of the Cuyamacas, extending into Lower California. 



TYPES. — 45 females, 4 galls. Holotype female, paratype females, 

 and gall at The American Museum of Natural History ; paratype females 

 and galls with the author; paratype females at Stanford University, 

 the Museum of Comparative Zoology, and the U.S. National Museum. 

 Labelled Descanso, California; February 23, 1920; Q. agrifolia; Kinsey 

 collector. 



On February 23, 1920, galls contained large larvae, while 

 many insects had emerged previously. 



This variety is readily distinguished by the very limited 

 amount of shading on the first abscissa of the radius ; the very 

 small or closed areolet is a fairly constant character. Both 

 this variety and maculipennis occur at Descanso, but none of 

 the many adults which I have show intermediate or differ- 

 ently combined characters ! Unfortunately I did not keep dis- 

 tinct .the galls from Descanso, and those from higher 

 elevations a few- miles from Descanso; for I did not realize 

 at the time that I was at the meeting point of two faunal 

 areas. It may be that the two varieties are confined to differ- 

 ent elevations. Maculipennis rather than descansonis is the 

 variety at Alpine, not ten miles from Descanso, and over fif- 

 teen hundred feet lower in elevation. Descansonis is prob- 

 ably confined to higher elevations of the Cuyamaca Mountains
