New Mexican gall wasps (Hymenoptera, Cynipidae) IV

Conobius (spicatus) strues, new species
Agamic form

GALL.—As described for the genus; distinguished as follows: color dark reddish brown, probably weathering darker; individal galls up to 9 mm in length and 6.5 mm in diameter; the whole cluster up to 23 mm in diameter.

[Description for the genus, shared with Conobius spicatus: Woody, seed-like cells densely clustered on stems, the clusters resembling small nubbins of dent corn. Each cell monothalamous, roughly conical, sharply pointed at place of attachment, expanding into a broadened, distinctly flattened top, the top centrally tipped with a small scar, the individual galls mis-shapened, often flattened on the sides because of the pressure within the cluster of galls: each cell covered with a thin, hard-papery epidermis which usually shrivels or becomes fluted, and sometimes flaker off in dried galls.]

The galls are practically identical to those of spicatus.

HOSTS.—Quercus undata, an evergreen white oak with ovate leaves which are soft pubescent beneath

RANGE.— Chihuahua. Santa Isabel, 6 E 6000'

LIFE HISTORY.—Adults: March 1
