distally than in rileyi; second and third joints' equilateral like the following ones, not oblique with one side produced as in rileyi; second joint sensibly shorter than the third ; third slightly longer than the fourth; fourth to ninth about equal in length, but the distal joints narrower than the proxin~al ; terminal joint similar to the penultimate one, whereas in rileyi the last two joints are dissimilar. Prothorax as in ~ileyi, shining, spiirscly punctured; elytra almut as in rileyi; covering at the sides about two-thirds of the first abdominal segment. Hind margins ofiibdom- inal segments narrowly testaceous; surface of segments shining, with broad shallow
punctures. At the sides the ventral segments encroach upon the dorsal area, the dorbo- ventral sutures being marked by deep sub- lateral channels. Legs as in rileyi; claws simple, with a strong basal bristle.
Huh. - Mesilla, New Mexico, about the
first of August, 1896, on a wall in which were many nests of Anthophora valloyum (Ckll.). This was sent at the time of its discovery to Dr. Horn, and it is much to be regretted that he did not live to publish an account of it. When recently in Philadelphia, I found it in Dr. Horn's collection, and was able to draw up the above description.
L. neomex-
icana is very distinct from Horaia mini~fi'jeii- cis, and quite sufficiently so from Leoniu rilsyi, as the following table of the North American Sitarini shows : -
Antennae 11 -jointed ; head, thorax and
legs bright ferruginous.

A NEW PULVINARIA FROM MASSA-
CHUSETTS.
Pulvittaria cockerelli, n. sf. $ Scale
yellowish brown, small, nearly hemisphericd in outline, slightly convex, mm. long, g& tnm. broad. Ovisac 7 mm. long, 3 inm. broad and a little more than r mm. in thickness. Texture soft, clear white, powdery and
sticky. Eggs small oval, white, situated in an oval cluster on the under side of the leaf beneath the ovisac. Newly hatched larvae clear white. 9 Scale cleared and mounted transparent slightly tinged with yellow. Legs, antennae, mouthparts and anal plates lightyellow. Antennae8segiiiented,3quite long, 4 next, 7 is the shortest (see table of measurements all in tnicromillimeters). The hairs on the antennae are as represented in the drawing, usuiilly 18. The length and breadth of the antennae seem to be quite con- stant in all of the material exiimined. Legs normal. Coxa broader than long, the legs usually have about 22 hairs on each (see fig- ure of leg). Marginal spines stout, bulbous Antenna. Leg.
at base, tips sharp, 6 micl-omilliinelers long, they are very easily lost in mounting.

llab. -On the under side of the leaves 01 Spiraea salicifolia, at Methuen, Mass., and on the under side of the leaves of Prino~ verticillatus, tit Andover, Mass., 1898 (in ithe woods sit each place). The young begin to appear about July loand thefull grown scale with ovisac the following May. The scales become dry and drop off about the last of June, none can be found in July. When I
sent tin's coccid Lo Prof. Cockerell last yexr, he, then being very busy, made a hasty
examination of my mount and scales with
ovisnc. Some of tlic ovisacs did not hxve any scales, and I did not state this to him at that time. The mount showed the antennae to be almost indeiitical with those of Lid- f-eusia -vibitrm Sign., and he supposed it to be a variety of that species. Being Inter doubtful of this, he requested me to study the insect with better material, and the result hns been to prove that it ciuinot belong to Lichtensin, as it does not have the scale cov- ered with its ovihac.

JANET'S RECENT OBSERVATIONS
ON ANTS, ETC.
Several recent papers* by Charles Janet, the well known authority upon ants, wasps, and bees, deserve mention. All are written in the concise and clear style characteristic of the author.
In Note 17, nine classes ofglandular organs are defined, of which the integumentary
system alone comprises eight pairs : (I) Unicellular gliiiuls opening separately at the bases of the antennae. (2) Well developed unicellu1:ir glands with n common reservoir at the base
of cither mandible. (3) Maxil-
lax-y glands. (4) Labial glands, derived from the larval silk glands. (5) Glands of the median segment, possihly odoriferous to ena- hie members of the same colony Lo recognize one smother. (6) Poison glamls of the fe- male, also accessory glands, alkaline in reac- tion, serving- the author suggests- neither to Uibricate the sting nor to complete the cornposition of the poison, but to neutralize superfluous formic acid reinnining upon the insect itself. (7) Glands of the sheath, also represented by certain glands in the male. (8) Glands of the ninth segment.
All the integumentary glands except the
~oison ylands secrete alkiiline fluids which are believed to protect ants from the dele- terious effects of their own formic acid. Tlms, Janet lincls that formic:iries give an alkaline renction which vavies in rapidity and strength n.ccording to the species of ant and Note i8. Aiguiilon de la llyrmica rubra.
