Mus. of Nat. Hist. Buk, 2:48 (Cecidomyia) The gall is a common, widely distributed deformity. It occurs generally in New York State and has been observed in other eastern states and recorded from both Illinois and Missouri. Adults were reared April 13, 1887 from blossoms of elder, Sambucus. taken at Cadet, Mo., April 9. The material was kindly loaned for study through the courtesy of the United States National Fig. 52 Youngomyia umbelli- cola, fifth antennal segment of ftrrale (enlarged, original) Fig. 53 Y o u n g o m 3' i a um- bellicola, terminal antennal segment of female.

Length mm, pale yellowish orange, the head moderately long, bread, the antennae long, slender, the segmentation distinct; breastbone bidentate, distinctly chitinized, the shaft slender, some- what irregular and with an expansion posteriorly; skin coarsely shagreened, the subtruncate posterior extremity with a submedian pair of well-developed, upcurved, chitinous spines resting upon a rather well-defined, chitinous plate.
