390 L. O. HOWARD 
ter?s return to Washington at the end of May other branches 
were taken from the same tree, and rearing experiments were be- 
gun here. More than 200 specimens of the new species of Pro- 
spalta have been reared, 25 to 50 specimens of Ablerus clissiocam- 
pae Ashmead, and 2 specimens of Perissopterus pulchellus Howard. 
We have, then, four species of primary parasites of Diaspis pen- 
tagona to place on record, as follows: 
1. Prospalta berlesei n. sp. One specimen reared in Florence 
by Professor Antonio Berlese from scales sent from Washington, 
and more than 200 specimens reared at Washington from June 
20 to July 5, from scales taken from the same tree. 
2. Ablerus clisiocampae Ashmead. Originally supposed to have 
been reared from the eggs ot Clistocampa, but, with little doubt, 
in reality reared from some Diaspine scale covered by the C%- 
siocampa eggmass. Subsequently reared from Chionaspis furfurus, 
in the District of Columbia, and from Aspidiotus forbesi on pear 
and apple, from Champaign, Ill., the latter rearing by Mr. W. G. 
Johnson. 
3. Perissopterus pulcheltus Howard. Originally reared from a 
Lecaniodiaspis on linden in the Distriet of Columbia in 1879; la- 
ter from a Lecaniodiaspis from East Atchison, Mo.; from Chiona- 
spis pinifoliae from Providence, R. I., and from Aspidiotus forbesi 
on currant at Champaign, IIl., the latter rearing having been made 
by Mr. W. G. Johnson; now reared in two specimens from Dia- 
spis pentagona at Washington. 
4. Prospalta murtfeldtiù Hovard. Originally reared from Aspt- 
diotus uvae by Miss Mary E. Murtfeldt at Kirkwood, Mo., in 1888; 
later from Aspidiotus forbesi on cherry and currant by Mr. W. G. 
Johnson at Champaign, Ill., and now reared by Professor Antonio 
Berlese from Diaspis pentagona at Florence, Italy, received from 
Washington, D. C. 
5. There is also one, presumably hyperparasitie, reared by 
Professor Berlese at Florence from Diaspiîs pentagona received from 
Waskington, D. C. This is Tetrastichus canadensis Ashmead. 
It now only remains to describe the new Prospalta, remarking 
upon the strange fact that this presumably American species 
should have first been reared by Professor Berlese in Florence.
