_ Larva. Length 3 mm, stout, yellowish. Head (figs. 16a, 17) 
moderate size, roundly triangular, the antennae rather stout, biarticu- 
late. Breastbone (fig. 16b) greatly reduced, there being only a 
narrowly triangular, chitinous process apically. Body with the skin 
smooth, the segmentation rather distinct, each segment bearing an 
irregular, transverse row of rather stout, chitinous spines, the latter 
having a length nearly equal to that of the segment and laterally 
arranged in pairs. Posterior extremity (fig. 18) irregularly rounded, 
the posterio lateral angles each with groups of four short, stout, 
transparent spines. Cecid. a1547.

This species infests the green husks of the nuts of shell-bark 
hickory, Carya ovata, producing swellings and giving them an 
irregular appearance. The husk is so badly deformed occasionally 
as to burst open, leaving the nut uncovered even when very immature, 
portions of the husk forming wartlike swellings on the basal portion 
of the nut. This gall was taken by Baron Osten Sacken August 
9, 1860 near Rhinebeck, N. Y. On examination the husks were found 
to contain small, round cavities, often two or three together, each 
inhabited by pale reddish larva. The latter has a breastbone 
“ distinctly elongated, narrow, its branches short and square, ending 
in sharp angles anteriorly, instead of being rounded; the emargina- 
tion between them broad and deep.’ The posterior extremity of 
the body is smooth. This species has been recorded from Ontario, 
Canada, by Jarvis. 


Caryomyia sp. 
A number of irregular, dull greenish black margined or black 
blister galls (pl. 9) with a diameter about 3 mm, distinctly elevated 
on both the upper and under surface of the leaves and with a small 
nipple were variably scattered about the midrib and in some cases 
several were confluent. These specimens were taken at Nassau, 
N. Y., October 3, 1907. No adults were reared and the above 
generic reference is tentative.
