Some Rearings of Parasites. — Prof. H. A. Morgan, Entomologist to the Louis- 
iana Experiment Station, at Baton Rouge, La., sends us certain parasites, which he 
has reared, as follows: Telenomus graptw How., from the eggs, and Cratotechus brevi- 
capiiatus C. & D., from the caterpillar of Sierodonta bilineata; Tetrasiichus sp., from 
spider's nest; Chalcis ovata Say, from bagworm on flowering pomegranate, and from 
chrysalis of Argynnis on passion flower; Elaschistus sp., from Apatura clyton ; Enny- 
omma clistoides Town., and Sigcrfjyhus sp., from Chalcodermus aniens; Sarcophaga sp., 
from an adult scarabseid; and Chelonus electus Cr., from lepidopterous larvae. 
Another Swarm of Ants. — Mr. F. F. Fiske, of Mast Yard, N. H., writes us that 
last September, wheu forest fires were greatly feared, a quantity of smoke was seen 
rising above a group of pines. Instant investigation was made, when it was found 
to be a false alarm and the smoke was an immense swarm of winged ants. This 
note was sent us apropos to the interesting note by Mr. A. H. Mackay, of Halifax, 
N. S., published upon page 52 of the current volume of Insect Life. 
Horn Fly on Horses again. — Mr. L. F. Abbott, of the Lewiston Journal, Lewiston, 
Me., writes us that he has found the horn fly annoying horses at South Harper, Me., 
both in 1893 and 1894. The flies have been abundant near Lewiston from early in 
May to the last week in October of the present year. The remedy adopted is half a 
pint of pine tar to a quart of fish oil smeared upon the neck, shoulders, and along 
the back of the animals. 
The Barnacle Scale in Louisiana. — The well-known Florida barnacle scale 
(Ceroplastes cirripediformis), which occurs rarely upon orange and lemon trees in 
Florida, but more commonly, perhaps, upon Eupatorium and quince, [has, as we learn 
from Prof. H. A. Morgan, become extremely abundant in Louisiana (we assume in 
Baton Rouge). Prof. Morgan writes that it has simply ruined the China-ball trees, 
which on some of the streets are largely used for shade. To such an extent has this 
insect appeared that the city authorities are taking the matter of its extermination 
into consideration. 
The Hen Flea on Horses. — Prof. J. C. Hartzell, jr., has sent us specimens of 
Sarcopsylla gallinacea, which he took on horses in the region of Orangeburg, S. C. 
He is of the opinion that the occurrence is not accidental nor due to the proximity 
of chicken houses to horse stables, since for the past six months it has occurred upon 
horses which have been shipped by the carload to Orangeburg from various points. 
More Damage by Brochymena annulata. — Apropos to damage to apple trees in 
Virginia by Brochymena annulata, referred to in the first number of this volume (p. 47), 
Prof. F. M. Webster writes us that this insect injured both apple and plum trees 
in southern Ohio last spring,
