RHINOCEROS BEETLE—SAND BEE—CATTLE TICK. 
dum of what I now suppose was a rare opportunity to have studied this 
beetle. None is to be found. I am ashamed to own it, and to offer my 
memory of what occurred years ago. In fact, at the time, I noticed such 
things merely for my passing pleasure, without the least notion of in- 
teresting the world. It was as I mentioned: In March of 1868, a large 
post-oak tree I had cut for rails, posts, and wood, was found hollow at the 
top; the cavity some 10 feet long, and branching into the larger limbs, 
by 12 inches in diameter. I do not recollect seeing any large opening 
into the cavity. There were small holes, such as might have been 
made by woodpeckers and squirrels. Within, the trunk contained no 
nests of birds or other animals, but some decaying acorn hulls, sticks, 
and leaves. The lower half contained a black, damp mass of decaying 
vegetable matter, rotten wood and fungi. In this rotten and decaying 
mass were numbers of grubs, evidently grubs of beetles, and in size from 
linech to 4 in length; at the top, in looser, drier matter, were several 
pup, and amongst the old sticks and leaves numbers of perfect beetles. 
most of them dead and in pieces, but a few still alive. * * * 
I send you a small tin box containing the nest of a sand bee of some 
kind. There were four cells originally, as plowed up in a cotton field 
6 miles northeast of Selma, but the curiosity of a companion destroyed 
two of them before I was aware. A more curious thing, also, in the 
box—unless you have seen the same before—is a large tick laying her 
eggs. On the 10th of March the tick was found, full of blood, at the foot 
of a bank, where a cow had recently rubbed it off after carrying it all 
winter. I placed it in a box, with loose cotton on top. Two weeks 
later, looking at it, I found it had shrunken to half its original size, and 
the first mass of eggs was extruded. It should have been sent you 
then, but I was busy about other things and it was overlooked. Now, 
after eighteen days, it has continued to lay, and another mass is hang- 
ing to it, whilst the skin seems shrunken very much.—[ LAWRENCE C. 
JOHNSON, Selma, Ala., April 20, 1883. 
[The nest of the ‘“‘sand bee” was that of a species of Osmia, and the 
tick was the common Jvodes bovis. | 
TEE SCREW WoORM. 
Permit me to call your attention to the Texas *“* Screw Worm,” which 
was very troublesome to stock in Kansas last year. I am medically 
informed it is the Sarcophaga georgina. I send you a larval specimen. 
It kills a great many animals and some people. Neglected babies, 
children, and adults with nasal catarrh are sometimes afflicted and 
killed byit. Weare told that it flies into the nose of a man the same as 
the bot-fly in the nostrils of a sheep, and lays its eggs or young. In ani- 
imals a wound or blood attracts it: Calomel, chloroform, and carbolie
