unusual, although similar instances hare been brought to the attention of the Divi- 
sion before. This mite is readily amenable to the kerosene emulsion, particularly 
when a small quantity of flowers of sulphur has been added. — [September 11. 1893. J

I tried a little experiment during last August with our ordinary coal oil. I saw a 
number of my hogs were not doing well. They were continually rubbing against 
the fence or some post. I put one gallon of oil into my knapsack sprayer, put it on 
my shoulders and walked out to the pen. I could not get my hogs quiet enough to 
spray well, so I put some corn chop into their bos, and while they were eating I gave 
them an excellent covering of oil. very finely put on by said sprayer. My neighbors 
said " The hair will come off"' — others said, •■ It will blister.'" I awaited my result. 
Xext morning on examining their backs I found great loose scales of dirt and mange, 
and under these and among them were thousands of dead lice. Result — my hogs 
are smooth and slick, lice all gone. Have tried same in hen houses to kill chicken 
mites 3 also lice on horses. A flannel cloth saturated with best coal oil and rubbed 
over eggs from Bot Fly on horses' legs causes eggs to loosen and drop in a short 
time.— fE. H. Kern. Kansas. December 30, 1893. 
NOTES FROM CORRESPONDENTS. 
Larvae in a Child's Face. — A correspondent from Fort Collins, Colo., mentions 
a peculiar case of a child 15 days old affected with a subcutaneous larva on the right 
side of the face, neck, right arm, and hand. The '"'worms''' were inclosed in indu- 
rated sacks. Thirty-two were removed and in one case four from one sack. They 
are described as being about 3 lines long by 1 line wide. They were segmented or 
ringed, white in color with ligbt brown head, and sparsely covered with micro- 
scopic hairs. 
Larval Food of Euxesta notata. — Prof. J. B. Smith recently wrote us that he 
had reared this Ortalid fly from Onions and asked us whether we had ever published 
anything concerning its larval habits, since he had noticed in a foot note to the 
description of this species in Vol. m of the Smithsonian Monographs of Diptera, a 
statement by Baron Osten Sacken that he had received specimens from us reared 
from larva? in the pulp of Osage orange. Examination of our notes shows that we 
have reared the fly from cotton bolls from Alabama, from Sumach fruit from Vir- 
ginia, from bolls of Solatium carolinense in the District of Columbia, from Osage 
oranges in Missouri, and that Mr. Coquillett has reared it from Apple previously 
infested by Codling Moth in California. 
Change of Address. — Prof. A. J. Cook, for many years professor of entomology in 
tbe Agricultural College of Michigan, has removed to Claremont. Cal., where he is 
professor of zoology in Pomona College. 
Abundance of the Purslane Caterpillar. — Mr. T. J. Brewster, of Lucerne, Kans., 
writes us that the Purslane Caterpillar was extremely abundant in his vicinity dur- 
ing the summer of 1893. He considers this insect a positive benefit to the farmer 
since it rids the land of such an obnoxious weed. 
Road-dust Against Swine Lice. — Xoticing on p. 165 of the last number of Insect 
Life that road-dust is recommended by Prof. Osborn as a remedy against lice, Mr. 
T. J. Brewster, of Kansas, writes that the lousiest hogs he ever saw were confined in 
extremely dusty pens. He finds kerosene emulsion one of the most effective and 
cheapest of remedies. 
A new Food-habit of a Clothes Moth.— We have lately received from Dr. J. C. 
Merrill. U. S. Army, now stationed in Washington. D. C, a can of beef meal rejected
