lateral angles there is a stout, curved, conical process and just mesially 
a similar smaller process.

The small, pale orange midges were reared from a bud gall, pre- 
sumably loose, on tick treefoil, Desmodium species. Owing to the 
condition of the type material it was possible to prepare a detailed 
description of the female only. 
Hyperdiplosis eupatorii Felt 
191t Felt, E.P. Ent. News, 22:110-11 
The species was reared by W. H. Patterson, St Vincent, W. I. 
from a green, conical gall with a length of about 4 mm, and a 
diameter of 1.5 mm, on the upper surface of the leaves of Eupatorium, 
the insects pupating within the deformity. It is provisionally 
referred to Hyperdiplosis because of the reduced circumfila and the 
deeply and roundly excavated ventral plate. The antennal stems 
of the typical Hyperdiplosis are more produced and the claws more 
gtrongly bent than in this West Indian form. 
Hyperdiplosis americana Felt 
191t Felt, E. P. N. Y. Ent. Soc. Jour., 19:192 
The small, pale midges were reared in numbers from a section of 
dead, partly decayed wild fig branch collected by E. A. Schwarz 
at Paraiso, Panama, and forwarded to this office by H. S. Barber 
under date of May 15,1911. The adultsappeared from the 31st of 
May until early in June. This species is allied to the somewhat 
aberrant H. eupatorii Felt and can not be considered typical 
of the genus. It is easily recognized by the very greatly produced, 
slender lobes of the ventral plate.

The midge was reared presumably from mite galls in the 
inflorescence of Stachytarpha collected by W. H. Patterson, St 
Vincent, W. I. 
Hyperdiplosis bryanti Felt

The small yellowish male was taken in August 1907 by Mr Owen 
Bryant at North Adams, Mass. It is allied to H. americana
