PROCEEDINGS OF SOCIETIES. 
CAMBRIDGE ENTOMOLOGICAL CLUB. 
15 Fer. 1880. — 65th meeting. Mr. S: H. Scud- 
der read a letter from Mr. W: H: Edwards, who 
says he has received four specimens of Grapta 
faunus from Oregon. This species was not pre- 
viously known to occur west of Lake Winnipeg. 
12 Mar. 1880. — 66th meeting. Dr. H. A. 
Hagen gave a summary of the literature hither- 
to formed upon suction in the proboscis of lepi- 
doptera. Mr. S: Henshaw exhibited a living 
Lepisma saccharina which had eaten some large 
holes through a piece of soft white paper en- 
closed in the vial with it. Mr. S: H. Scudder 
showed, under the microscope, the tips of the 
proboscis of several species of butterflies, to call 
attention to the various appendages which may 
there be found. Mr. S: H. Scudder showed spe- 
cimens illustrating the manner in which Oecan- 
thus niveus lays her eggs. Brunner thinks the 
American and European species are the same, 
but Scudder doubts this. The American species 
or form lays one egg in each hole, but the Euro- 
pean species lays three eggs in each hole. Dr. 
H. A. Hagen exhibited a Sphinx imago, in which 
the head was extremely small. 
9 Aprit 1880. — 67th meeting. In accordance 
with the amendment to the constitution, adopted 
at the last meeting, Clifford Chase Eaton was 
elected Librarian. 
(ive 
Mr. 8: H. Seudder showed two plates of fig- 
ures illustrating fossil insects from the Green 
River shales of Colorado, and said that the basin 
of Florissant, whence these fossils are obtained, 
is filled with volcanic ash and volcanic sand. Dr. 
H. A. Hagen gave some account of his recent 
studies upon the larvae of Agrionina, and men- 
tioned that the larva of Blepharocera [a dipteron| 
had been discovered. Mr. S: H. Scudder said 
that he had finished the preparation of a paper 
on Retinia frustrana, which is destroying Pinus 
rigida on the island of Nantucket, Mass. He 
finds that the moth has two broods in a year. 
14 May 1880. — 68th meeting. Mr.S: H. Seud- 
der described the formation and character of the 
insect-bearing peat-beds of Nantucket,... and 
gave notice that Mr. Whitman, residing at No. 
5, Kaga Yashiki, Hogo, Japan, wishes to ex- 
change Japanese insects for others. ... 
11 June 1880.— 69th meeting. Mr. S: H. 
Scudder said that on 5 June he found the ima- 
gos of Retinia frustrana in innumerable abun- 
dance at Nantucket, and noticed in them a habit 
directly contrary to one he had noted on a pre- 
vious visit,in May. On the previous visit, when 
nearly all the specimens were males, they alighted 
on the tip of a needle of the pine, ran down to 
the brown part of the twig, and then placed 
themselves in a position transverse to the twig. 
At this time (June), when nearly all the imagos 
were females, they alighted at the base of the 
needles, ran thence to the tip, and rested longi- 
tudinally upon the needle. Mr. Scudder sought 
in vain for the eggs, which are probably laid be- 
tween the leaf-scales, near the tip of the shoot, 
and thinks the time of laying may be later. 
He obtained eggs by confining the imago in a 
pill-box. At the end of September 1878 about 
a half of the insects were larvae and about a 
half were pupae. The-imagos appeared in the 
latter part of April and early part of May. The 
corresponding European species, Retinia duplana, 
which injures Pinus sylvestris, develops into pu- 
pae rapidly in the spring, but the pupae lie 
eight months undeveloped, according to Ratze- 
burg.
