Page:The Gall Wasp Genus Cynips.pdf/215

Rh From the type galls which were collected in December, adults emerged indoors in January. This, and the data for the other species of the subgenus, leads us to expect normal emergence out-of-doors in December or early January.

This variety was described from a southern Coast Range area to which it may be restricted. On the other hand, galls indistinguishable from those of typical guadaloupensis are common in the mountains of more central California and in northern parts of that state, and two insects which I bred from Elk Mt., Lake County material, seem identical with the types of guadaloupensis. Perhaps all of the other more central California gall records listed in the introductory discussion of this species may apply to our present variety, but I prefer to withhold judgment until we can examine more insect material from the area. The Oregon and southern Arizona records for guadaloupensis will undoubtedly prove to represent distinct varieties.

The thin, flattened galls of the present variety are very different from the elongate, pouch-shaped galls of variety insolens and the usually bowl-shaped galls of patelloides; but some of the younger and stunted galls of patelloides are as thin as those of true guadaloupensis. In the latter case, the insects and the geographic ranges must be relied upon in making determinations. In addition, the galls of Fullaway's pattersonae (described in 1911, Ann. Amer. Ent. Soc. 4:352) are hardly distinguishable from thin galls of guadaloupensis. Pattersonae, however, represents an unrelated genus. The galls of pattersonae occur on the blue oak, Q. Douglasii, while all of the varieties of our present species are restricted to the canyon oaks, Q. chrysolepis and Q. Wilcoxii.

I am indebted to Dr. McCracken, of Stanford University, for the opportunity to study the types of this variety in connection with the present revision of Cynips. The holotype is light yellow rufous in color and appears to be not fully pigmented. The wings of both the holotype and the more normal (tho headless) paratype are distinctly shorter than the wings of either insolens or patelloides, but not as short as the wings of Weld's San Bernardino material of this species. Fullaway's statement that the areolet is "distinct" should not be taken to mean that it is open, for it is entirely closed in the type material.
