PROCEEDINGS OF SOCIETIES. 
CAMBRIDGE ENTOMOLOGICAL CLUB. 
(Continued from p. 369.) 
14 APRIL 1882.—8S4th meeting. Mr. S: H. 
Scudder read a letter from Prof. J: H: Com- 
stock on his recent researches in entomology. 
Mr. R. Hayward made afew remarks on 
the food of several New England birds. He 
stated that his remarks were only prelimin- 
ary, since he lacked sufficient material to ren- 
der his work conclusive. Dr. H. A. Hagen 
expressed his surprise that no hemiptera had 
been discovered in the stomachs of the cliff- 
swallow (Petrochelidon lunifrons) of which 
three specimens had been examined, as he 
had taken young nestlings of the European 
swallow literally filled with aphides. 
Dr. Hagen showed, from an as yet unpub- 
lished monograph, some plates of fsoczna 
and atropfinma. He stated that all the fossil 
species of Psocus and Efpipseocus are similar 
in all respects to the modern species of those 
genera, while on the other hand, there is con- 
siderable difference between the modern and 
fossil species of atropfzva. All the species of 
Atrofos are furnished with the organs neces- 
sary for producing sound, but the sound, if 
produced, is probably not audible to our ears; 
in the other genera these organs are entirely 
wanting. 
Mr. S: H. Scudder exhibited a specimen of 
a fossil insect probably belonging to the ¢hy- 
sanura. There is apparently no head but 
PSP CHE. 
this part is reduced to mouth-parts which are 
distinct, and evidently concealed, when at 
rest, within the second thoracic segment, and 
can be thrust beyond the body. This pecu- 
liarity is not individual, as a number of speci- 
mens examined by Mr. Scudder possess the 
same characteristic. He then showed draw- 
ings representing the insect restored. 
NOTES ON PTEROPHORIDAE OF 
NORTH AMERICA. 
The following references were collected, 
for the most part, in endeavoring to find 
out if the glandular hairs of some of the 
larvae of pferophoridae had been studied. 
The notes here given cite the original and the 
prominent subsequent descriptions of larvae 
of Aterophoridae of North America’ that have 
been reared. To these citations are added 
references to published figures of different 
stages, to notices of food-plants of larvae, to 
localities of capture, and to observations on 
a few species that I have taken or reared. 
For the identification of the pterophoridae 
of my collection I am indebted to Prof. C. H. 
Fernald, of Orono, Maine. 
Chrysocorys festaliella WHiibn. (Wocke, 
Cat. 2705). Imago figured by Walsingham 
(Pteroph. Cal. and Oreg., 1880, p. 1-2, pl. 1, 
fig. 1), by whom it is said ‘‘They appear to 
be in all respects the same as European spec- 
imens, having also the same habit of frequent- 
ing one or more species of the genus Rubus.” 
Found in Cal. and in Europe. 
Chrysocorys felicella Wlism. (Pteroph. 
Cal. and Oreg., 1880, p. 2-3). Walsingham 
reared this species from larvae feeding on two 
kinds of Orthocarpus (1. c., p. 3), and fig- 
ures its pupa and imago (/. c., pl. 1, fig. 2). 
Oregon. 
Chrysocorys erythraeella Clemens (Proc. 
Acad. nat. sci. Phil., 1860, p. 171). Clemens 
(7. c.) describes the larva and pupa, and~ 
writes ‘‘The larva feeds on the fruit racemes 
of sumach [/?hus]” in July. Pa.?

pasted on slips by those persons who thus use the Bibli- 
ographical record.
