ate, normal, not elongate; black, not shining, marked in white as before, the lines all nar- row, dotted, somewhat broken; joint 12 a little enlarged, the addoreal line widened on it ; anal feet projecting laterally. No shields ; tubercles and setae obscure, their bases a little enlarged, making the surface of the body somewhat irregular ; traces of a sub- dorsal line ; abdominal feet pale dotted out- wardly.
Stage IV.- Head dull black, white dotted, the upper faces of the lobes nearly solidly black, but many dots across clypeus in two transverse bands ; width I. 1 mm. Body dull black with fine, broken, addorsal and more continuous but narrow substigmatal white lines; traces of the other lines as dottings. Tubercles small, slightly elevated; setae short ; black. Cervical shield, anal plate and feet slightly brownish diluted ; no corn- ified shields. Segments wrinkly subannu- late.
Stage V- Head broad, erect, roundedly
bilobed; sordid white in ground color, a COCCIDAB AND AI.EURODIDAE.- TWO pa-
pers, embodying contributions to our knowl- edge of the Coccidae and Aleurodidae, have just been completed in the laboratory of en- tomology at Stanford University.
The pa-
pers are of such size that some time must elapse before their publication, so that an immediate brief statement of their contents will probably be of interest to entomologists. "Coccidae of Coniferae" is the title of a paper by Geo. A. Coleman, based on material col- lected by the author in the summer of 1901, in the course of a trip on fool and horseback of a thousand miles through the great con- iferous forests of Northern California. This expedition was made for the express purpose of gathering specimens and notes for a study of the conifer-infesting scale insects. Mr. Coleman collected 22 species of Coccidae from 26 species of conifers, ten of the species black band on the vertex, one across apex of clypeus, broken, one above mouth, irregular and with dots between ; width 1.5 to 1.8 mill. Body smooth, rather robust, normal, not
elongate; setae and tubercles minute except tubercle ii of joint 12 which is elevated. Color variable. Dark gray, finely lined. Thoracic feet red-brown or black. Body
lines addorsal, subdorsal, lateral and stigma- tal, the addorsal ones enclosing black spots, or a continuous black space or broken up by red and white dots. Ground color dark
purplish shaded with black laterally and sub- ventrally and with reddish sligmatally ; a dark swelling behind the spiracle ; substig- matal line usually yellow, narrow, distinct ; other lines more or less broken and dotted ; all the surface finely dotted and mottled. Feet sometimes reddish.
The larvae entered the earth May 24th and emerged the following March. Eggs were
obtained which hatched March 24th and the larvae matured again before the end of May. being described as new. Of these ten, iin- mature stages of four are described, and the complete life history of one. The paper also includes a compiled list of the Coccidae re- corded from the Coniierae of the world, and a host list with distribution. There are in- cluded also notes on the economic status of the conifer-infesting scales.
"Aleurodidae of California" is a paper by Mrs. Florence E. Dorsey which describes
twenty new species of aleurodids found in California, thus increasing the number of known N. A. species in this family from 40 to 60. In the case of every one of these 2.0 new species the immature stages have been studied by the
author and arc described in
detail. It is unnecessary to say that these accounts of the post-en~bryonic life history of so many aleurodid species constitute a really important contribution to ow Icnowl-

THE PUPA OF MERMIRIA TKXANA HRUNER.
BY T. U. A. COECKRELL, EAST LAS VEGAS, N. MEX, Orthopterists have not usually paid
much attention to the pupae of grass-
hoppers ; partly, no doubt, because they rarely offer any remarkable characters,
and partly because they often shrivel
and lose their natural colors, when
pinned in the cabinet. The pupa of
Mermiria. texana, now described,
is a
very striking and beautiful creature
when alive, and it seems well worth
while to present an account of it.
'2 . Length 34-36 nun., antennae 104
mm., dorsal surface of head c;& mm.,
pronotum $4 mm., tegmina 8 mm., end
of tegmina to tip of abdomen 16-18
mm., femur 16 mm., tibia 15 mm.,
breadth of thorax 4 mm. 2 I spines on
outer margin of hind tibia. Brown of
various shades, with pure white longitu- dinal stripes ; top of head with a broad median longitudinal pale sepia band,
narrowly edged with darker; on each
side of this a broad pale apricot or red- dish-ocherous band, clouded with pale
gray, and externally bordered with
white, the white border running through
the upper edge of the eye; next to this
a broad dark sepia band, also bordered
below with white; then a dilute gray
band, marbled with lighter veins and at
its lower part spotted with darker; this lower spotted part bordered below with
white; running from below the eye,
bordering on the lateral carinae of the
face, is a pale reddish-ochreous
band.
Eye gray, its upper part spotted, its
lower part striped with grayish-white.
Face gray mottled with blackish, the
median carinae pale. Antennae a warm
brown, distinctly triquetrous towards
base, not nearly so broad as the shorter diameter of the eye. The prothorax
continues the longitudinal markings of
the head, but the median zone, is mot-
tled with dark gray, and its ground-color is inclined to purple, with the median
carina, which is very distinct, is indi- catcd by a pale line. The subdorsal
dark band passes backwards along the
thorax and abdomen, crossing the tcg-
mina, which thus have their lower half
dark and the upper a light warm rcrldish- oc11reo-n~. On the sides of the thorax
the dark band is broadly bordcrcd below
by white ; but on the abdomen it is nar- row, and is bordered above by white.
