well known students of Acarina are: G. Leonardi, F. Fanzago,

mer, E. Claparede, L. Karpelles, M. P. Megnin , E. Perrier
. ‘The Acarina form an order under the class Arachnida. Some
rities have endeavored to make a separate class of Acarina,
ost authorities, however, do not believe that there are suf-
to the spiders in more ways than one: they have four
: of legs, almost without exception, in the adult form; they
| distinct head and no antennae. Mites not only have a ste
ial resemblance to spiders but their habits and food in
ases are nearly identical with those of spiders. The Tetra-

.... METHODS.
Collect ing. In making my collections several methods were
i, depending upon the number of specimens desired and also
pe habits of the mites. For most purposes I used vials
: camel's hair brushes. By moistening the point of a brush
hen applying it to a mite, the latter could be transferred
‘<i
. vial. This method succeeds with mites which have a hard or
*
In collecting the latter, one should not moisten the
1, since it adheres to the specimens so strongly that the
When large quantities of specimens were desired, two meth-
ods were used. The eres of these is a method devised by A. Ber-
| lese, who employed an apparatus described in the "Entomological
a Vol. 27, No. 2, Feb. 1906, pp. 49-54, Following the di-
alia given by Berlese, we made a galvanized sheet iron boil-
+
» cylindrical in shape and about two and a half feet long by
| eh.
fourteen inches in diameter. Inside this cylinder and extending
full length, was a large funnel, about one foot in diameter
at the top and tapering to about three fourths of an inch in
| diameter at the bottom. The mouth of the funnel nabawe thr ough
| the base of the boiler. In operation, the boiler was filled with

of Pa gas burner. The boiler was supported in an upright position
’ ‘al tripod. Now a pan with a perforated bottom was placed over
the top of the funnel anda bottle containing a little water was
placed under the mouth of the funnel. The apparatus being ready,
“the material containing mites, and other small organisms was
"| places in the perforated pan. The mites upon feeling the warmth
would go down through the holes in the bottom of the pan, and
| upon reaching the funnel would tumble down into the bottle, the
_| funnel being too hot and too steep for the mites to remain long
| “upon its surface. Mites may thus be collected from soil, dead
| leaves, straw, grass, moss, manure, and debris of various kinds.
= pomeoond method, which I employed with great success, was
i as follows: first, I would sift the mites from the materials in
| which they were contained, upon a white cloth (a large handker-
7 chief is quite sufficient). This was done in the field. After
@ quantity of very fine debris containing minute organisms had
]
| thus been sifted upon the cloth, it was taken up and the contents
‘Can
| poured into a large bottle. These siftings were taken to the
- | laboratory and then poured out upon a hot plate, which was sus=
| pended over the top of a large funnel. The mites were driven
| out of the siftings by the intense heat and tumbled down through
|G
‘ the funnel into a large bottle containing a little water, which
é
| prevented the mites from crawling out of the bottle. This method
has several advantages over the Berlese method: first, it does
‘away with the necessity of carrying home a large amount of mae
terial; second, an immense number of mites can be quickly collect-
ed in a small bottle, thus permitting one to gather large quan-
| tities of specimens in a short time} third, no dirt comes down

| elevate the cover glass on glass supports or on glass or rubber
| rings, though with sufficient care, good mounts of the harder

of some Gamasids the male has a spur on the second pair of legs

A great many kinds of mites will sometimes be found living
together or apparently so. Thus I have noticed no less than a
dozen species of mites wintering under the same board.

a The texture of the integument varies greatly in the dif-
i. ‘
| forms. In Sarcoptidae and Eriophyidae the integument is
rather soft. In Gamasidae and Ixodidae, however, it is leathery
and tough, and sometimes very hard. The Oribatidae have a heavily
| chitinized integument, and on account of this were long known as
ie
"beetle mites." The body of mites is usually clothed with hairs,
which vary greatly in size, form and number. Often the hairs are
1

| small and simple. Some of the Trombidinae, however, have feathery
4 Powel and others clavate hairs. Pectinate bristles are frequent
| on the anterior part of the body and legs and in some genera over
| the entire surface of the body. The hairs are so thick in the
case of some Trombidinae as to almost completely hide the integu-
ment, though certain Oribatidae, on the cther hand, are hairless.
| The study of the internal anatomy of Acarina is as difficult
| as it is interesting.
| The following list of investigators and their works is very
helpful for a study of the internal anatomy of Acarina.

The mandibles are short and broad at the base; at the mide
dle on e€ach side is a large curved bristle and at the base on
each side is a similar bristle of about one half the length of
the first named. |
The palpi are longer than the mandibles; second segment
much the longest being almost as long as the mandibles; fourth
segment not quite as long as the third, both together as long as
‘|the distal segment; distal segment broader at the tip than at the
base and bearing two,large bristles, the inner of which is spiral
shaped, very characteristic of this species. Two small bristles
are situated at the base of the larger ones.
The cephalothorax is longer than broad with a neck in front,
sides convex. At about the middle on each side is situated a
very long bristle, as long as the mandibles, behind which are the
eyes, two on each side. Just behind the eyes and a little median
to them are two bristles which point outwards and backwards. lLat-
eral to these on the margin is a pair of bristles equal in length
to the former.
The abdomen is oval, tapering slightly towards the poster-
jor end. It has a row of bristles on the dorsum on each side
about four in numbers There are several bristles on the poster-

very close to the medien line.
