9 (2) Chalcis robusta Cresson. 
This species was described by Mr. Cresson (Proc. Ent. Soc. Phila., iv, 
1865, p. 101) from four Cuban specimens. There is one specimen in Pro- 
fessor Eiley's collection which agrees perfectly with the description, and 
-which was bred by Mr. Hubbard, September 14 or 15, 1881, at Crescent 
City, Fla., from a cocoon of Lagoa opercularis. Mr. Hubbard, also, in 
June or July, 1882, bred another specimen of this insect from a chry- 
salis of Papilio crespho rites, also at Crescent City. The chalcid issued 
from a large circular hole cut through the thorax of the pupa. [Dept. 
Agr. Coll.]
