Disholcaspis mexicana (agamic)

Kinseyella lapiei (agamic)

Holcaspis mexicana, sp. nov.

Gall. In a compact mass around the terminal twig of a species of oak. More or less rounded with the sides usually flattened and pressed out of shape. Smooth, somewhat shining, clay brown more or less tinged with red. Hard and woody with a single rounded larval chamber near the base of the gall and firmly imbedded in the hard inner substance. The individual galls measure from 8-18 mm. in diameter and the entire mass 30 mm. in length and 25 mm., in width. 

Habitat: Guadalajara, Mexico. (D. L. Crawford.) The specimen I received from Prof. C. F. Baker.

Holcaspis weldi, sp. nov.

Gall. In clusters on the terminal twigs and leaves of Quercus reticulata. 

Monothalamous. Globular, thin-shelled, yellowish and tinged various shades of pink and red, covered with a dense rusty brown, pubescence, which may be rubbed off with the fingers. Inside there is a rounded kernel held in position by radiating fibers which are covered with a moss-like substance. The inner side of the shell is densely covered with a rusty brown moss-like substance. Diameter 20-40 mm. 

Habitat: Mexico. 

The galls were purchased by Mr. Lewis H. Weld from a woman at a fruit stand on the street in the Mexico City and the specimens evidently came from the nearby mountains. The galls were bought September 12th, 1910 and the adults emerged between October 2nd and 9th. The oak was kindly identified for me by Dr. N. L. Britton.
