PROCEEDINGS OF SOCIETIES.
CAMBRIDGE ENTOMOLOGICAL CLUB.
(Continued fromp.f6.)
14 MAY 1886.-The 120th meeting was held
at 61 Sacramento St., Cambridge, 14 May
1886. In the absence of the president, Mr. P. S. Abbot was chosen chairman.
Mr. S: H. Scudder showed wood-cuts from
Miall and Denny's work "The structure and life-history of the cockroach," and exhibited impressions from the different plates used in printing the plate offte~inae in his own work on New England butterflies.
These impres-
sions illustrated in a clear manner the pro- cess by which the figures are toned to their right color.
Mr. R. Hayward exhibited specimens of the species of Nebria collected by him in south- western Colorado during the past summer
(1885) and remarked briefly on their distribu- tion and relative abundance. Among the spe- cies obtained were N. ovz~ennis (?), N. $ur- furata, N. obliqua, N. trifaria and others. The specimens referred to N. ovipennis were all found at altitudes above 10,wo ft. Many specimens of N. fztrjurata were obtained from under the bark of logs which had been washed down by a tributary of the Gunnison river.
Mr. F. S. Child showed two specimens of
a species of Cassz'da from the cave of Ele- phantine, India.
Mr. G : Dimmock exhibited a case of some insect or spider, which had been found on a tree. It was made of grass and had a perfect lid.
I I JUNE 1886.-The 121st meeting was held at the secretary's room, No. 36 Grays, Cam- bridge, 11 June 1886. In the absence of the president, Mr. S: H. Scudder was chosen
chairman.
Messrs. S: 11. Scudder and R. Hayward,
remarked briefly on a collecting trip, which they had recently made to the White Mts., N. H.
Mr. S : H. Scudderstated that he was fairly confident of having seen Chionobas semidea near the summit of Mt. Washington. The
species has not been previously noted earlier than the first week in July, and if the supposed specimens of C. semidea belonged in reality to that species, it would seem that there must be two broods in a season.
8 OCT. 1886.-The 122d meeting was held
at 61 Sacramento St., Cambridge, 8 Oct.
1886. In the absence of the president, Dr. G : Dimmock was chosen chairman.
Mr. J. H. Emerton exhibited a figure of a male and female pink grasshopper (a variety Amtlycocv$fta oblof~g~~olia), which he had drawn for Mr. S : H. Scudder.
Mr. S: H. Scudder remarked at some
length on this variety. The first recorded specimen of abnormally red locnstarian was taken in the mountains of Pennsylvania,
but belonged to a distinct species, A. rotun- difolia. Four specimens of the red form of A. oblongifolia were taken during the past summer at Woods Holl, some of which were seen by Mr. Scudder while alive. They ate golden rod (Solidago) with avidity. Mr.
Scudder has been looking up the biblio-
graphy of the subject, in hopes to remark further upon it at a subsequent meeting of the club. Brunner von Wattenwyl records a specimen from Pennsylvania with violet ely- tra, and also mentions a dimorphic form of Pnrhe 5 069-70 (ore. 1903). hfp //psyche aitclub org/5/5.tÌö6S htnii

the neighboring genus Scufhttra from Bra- zil. It has been suggested that since chloro- phyll is found in certain insect tissues, the color might be changed by frost, but this could not have been possible in the Woods Holl specimens, as they were found too early in the season.
Mr. J. H. Emerton exhibited figures of the eggs of diurnal lepidoptera, which he had drawn for Mr. S : H. Scudder, a figure of the micropyle of a species of hesperid, and fig- ures of the larvae of various butterflies. Mr. S : H. Scudder showed a figure of the pupa of Feniseca taqz~i?ziu.<r and remarked at some length on the habits of this interesting species. The chrysalis has a curiously ex- panded ci-emaster. The larva differs very much from those of other copper-butterflies with which it has been placed, by having large protruding legs and a scarcely retrac- tile head, while in its earlier stage, according to Mr. W: H. Edwards, it iscompletely cylin- drical, and in no way onisciform. The egg is not pitted, but only possesses polygonal marking.
Dr. G: Dimmock asked if there had been
any study of the mouth-parts of the larva ofFeniseca, with reference to any modification for its insect food.
Mr. J. H. Etnerton exhibited a drawing of a wasp in the act of eating a fly. [See PSYCHE, May 1888, v. 5, p. 54.1
Mr. C : W. Woodworth stated that the only wasps that sleep with their mandibles grasp- ing upon grass or sticks were males of .@he- gidae.
Mr. S : H. Scudder showed eggs of Argyn- nt's idalia. Most of the eggs were laid upon the lace with which the butterflies had been covered during transportation, and not upon the violet leaves which had been placed with the butterflies. Some of the eggs were laid upon the lace whilein the cars, the butterflies being in a dim light under a seat.
All the
eggs were pushed through by the ovipositor of the female so as to stand on the outside of the lace.
held at 61 Sacramento St., g April 1886. In
the absence of the president, Dr. G: Dim- mock was chosen chairman.
The additions to the library were an-
nounced by the librarian.
The secretary stated that a reply had been sent to the invitation to attend a celebration of the fiftieth anniversary of the foundation of the Verein fur naturkunde zu cassel.
Nominations nos. 136-142 w-ere acted on
and the following persons elected to Active membership: Prof. T: J. Burril; Champaign Ill : W : H. Garman, Champaign 111 : Clar- ence M. Weed, Champaign 111 : C : A. Hart, Champaign 111: T: F. Hunt, Champaign
Ill : Prof. C. Robertson, Carlinville, 111 : C : W : Woodwortj-i, Champaign 111.
Mr. S. H. Scudder spoke of a recent paper by Dr. Paul Oppenheim of Berlin upon fossil lepidoptera, in which new light was thrown upon some hitherto insufficiently known
fossils from Solenhofen which had been
referred to hemiptera, lepidoptera and hy- menoptera. Dr. Oppenheim claimed, and
apparently with some reason, that they
should be referred to a distant archaic type to be considered the progenitors of lepidop- tera. Two new Jurassic forms were described from Siberia which should probably be re- ferred to the same archaic type, though
looked upon by Oppenheim as true lepidop- tera.
The Club then visited the laboratory of
Dr. Diminock, who showed his apparatus
for rearing insects in constant increased temperature. He also showed some speci-
mens of Hi-ppodamia co~zvergens which had been thus reared, and remarked on the differ- ence in time of development and the varia- tions caused by this artificial method of rearing. He further remarked on observa- tions he had made as regards the time of appearance of the spots in various species of coccinellidae.
Prof. Alpheus Hyatt said that he had been much interested in Dr. Dimmock's exper-
iments on the acceleration of development. as 70 p6'TTIL!?. [June 1888.
