December 1892.] PSYCHE. 365
Sixth stage,-Nearly as in the two previous stages; width of head 3.2 mm.
The dorsal
space is partly filled in with blue, except for a black edging to the dorsal white spots, a black spot on each side of the white spots at their obsolete junction and the short orange red streaks supplementary to the subdorsal orange red line. The white spots on joints 3 and 4 are larger than the others, single, elongate, and in some examples the posterior white dot on all segments is partly orange or rarely obsolete. The blue band is minutely black dotted, followed by the pale orange lateral line which is rather irregular. Space below, blue gray, the substigmatal line and the one along the bases of legs yellowish faint and broken, or obsolete ; spiracles large, black; feet gray; venter blue gray with a median row of black spots. The cervical
shield and anal plate are blue gray tinged with black. Subdorsal warts on joint 2
rather large; joint 12 enlarged a little dor- sally. Dorsal hair very scant, blackish, the subventral hair thick, partly silky white with some dusky and reddish hairs intermixed. Cocoon.-Enclosed in anouter layer of silk, elliptical thin, composed entirely of silk, made opaque by an exudation from the anus of the larva, which dries into a pale yellow powder. Size 25 X 8 mm.
Pea. - Cylindrical, posterior abdominal
segments rapidly tapering, rounded at both ends, no cremaster. Color black, rather
shiny, covered with short brown pile, except the cases which are bare. Length 18 mm. ; width 4 mm. Duration of this stage 26 days. The moths appear during July.
Food plants. - Oak (Quercus), poplar
(Populus), willow (Salix), alder, (Ainus), wild rose, (Rosa), peach and cherry (Prunus), apple (Pyrus) and others.
Habitat.-Oregon and Washington west of
the Cascade range.
Found at Portland and
Bonneville, Oregon, Seattle and Vancouver, Washington. This is the common Clisio-
campa of the Pacific Northwest and takes the place of C. disstria of the Atlantic States. It is abundant in the valley of the Columbia, but becomes more rare to the north. But
two larvae were seen in Seattle, Wash., while in Portland, Or., many fruit and shade trees were largely defoliated by the larvae, and they were frequently observed resting in large compact masses on the tree trunks. A LOWER SILURIAX INSECT FROM SWEDEN.
-For a long time the Devonian insects ofNew Brunswick were the oldest known from any part of the world. Seven years ago, however, Brongniart discovered in the lower part of the upper Silurian of Calvados,, France, a single wing which he regarded as a cock- roach and named Palaeoblaftina douuiZZei. And now Moberg announces the discovery
of an hemipterous insect, which he calls Protocimex silzwicus, in the still older rocks of Flagabro in Scania, belonging to the upper members of the lower Graptolitic slates, that is the upper part of the lower Silurian. Figures are given in the Forhandlingar of the Swedish geological society.
ENTOMOLOGICAL NOTES.- The first signa-
ture of a new general Catalogue of Hemiptera has just been issued by Lethierry and Severin at Bruxelles. The arrangement is systematic down to the genera but the species are given alphabetically and the number of species added at the end of each genus and sub-
family. The present sheet includes a portion of the Pentatomidae: the Plataspidae (19 genera and 187 species), the Corirnelaenidae (10 genera, 66 species) and a few Scutel- leridae. It will prove of great service. Entomologists everywhere will regret to
hear that the serious illness which has, for the past two years, incapacitated Dr. H. A. Hagen renders it improbable that he will be able to do any further work. Dr. Hagen has had charge of the collections of insects in the Museum of comparative zoology at Harvard University since October 12, 1867, and during this long period of twenty-five years has applied himself with entire devotion to the interests of the department.

value and present excellent condition of the collections are the result of his faithful and disinterested work. Recently the department has been placed in charge of Mr. Samuel
Henshaw.
In a "partial catalogue" of the animals of Iowa published by the Iowa Agricultural
College, Prof. H. Osborn enumerates 183
species of Ichneumonidae, Cynipidae and
Tenthredinidae, 80 butterflies, 357 moths and 12 j j Coleoptera.
Some interesting observations on the habits of the young of mole-crickets are given by Dr. E. W. Doran in Science for Oct. 14.
Among other things he finds that previous to their first moult they can jump to the distance of five or six inches.
The notes and figures of Myriapoda left by the late A. Humbert are to be published
shortly by the Socidtd de physique et d'his- toire naturelle of Geneva under the super- vision of Dr. H. de Saussure. The text is rather meagre but the figures are valuable and finely executed.
PROCEEDINGS OF SOCIETIES.
CAMBRIDGE ENTOMOLOGICAL CLUB.
14 October, 1892. -The 172d meeting was
held at 156 Brattle Street.
Mr. S. H. Scud-
der was chosen chairman and Mr. A. P.
Morse secretary pro tern.
Mr. S. H. Scudder reported the capture of Anthomaster leonardus near Gardiner, Me., further east than it was before known; the female was seen laying eggs Aug. 29th on Agrostis scabra; these hatched in about 20 days, but the larvae refused ordinary grasses, and as they were as plump when a month
old
as when born, it seemed probable that
their habit was to hibernate without first feeding.
Mr. S. Henshaw reported Callidryas
eubule- as not uncommon this year on Nan- tucket in the latter part of September.
