stout setae laterally near the posterior fourth. At the posterior 

 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 



1 91 1 Felt, E. P. Ent. News, 22 : i lo-i i 



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 i . 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 roimdly excavated ventral plate. The antennal stems 

 of the typical Hyperdiplosis are more produced and the claws more 

 strongly bent than in this West Indian form. 



Hyperdiplosis americana Felt 



191 1 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 adults appeared 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 Stachjrtarpha 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 toH. americana
