specimens weresent tohim by
Prof. C.H.
Fernaldwho
receivedthem
from a corres-pondent in California.
Mr. Howard
concluded hiscommunica-
tion with abrief account of the literature of the
Jumping
gall.Mr. Howard
also mentionedthefactthatthewellknown
4iDie- back" fungusof theOrange had
been described inMS. by Mr.
Ellis asNectria coccicola,* the describer having seen specimens under
which were some
of thecommon
Mytilaspis scalesof the Orange, and therebyformingthe impression thatthe funguswas
parasitic on the scales.
Mr. Smith
called attention tothe fact thatinthegroup
ofBom-
bycids classedasAttacince
and
Ceratocampincetheantenna had
in the cf two. pectinationsto eachjoint,
and
proposedto limit the family Saturniidce bv this character.He
explained the differ- ences between the proportions of thebranches andtheir relative situations, andthinks the characteravery important oneinclassi- fication.Two
sub-families are well indicatedby
the fact thatin the Attacincethe pectinations extend tothetipof the antennae, while inthe Ceratocampincethey extend only
two
thirds thedis- tance andthen end very abruptly.fDr.
Marx
read apaper on the genusThelyphonus,
exhibiting atthesame
timea carefuldrawing
of theNorth American
Th.gigante2is.
He
stated that Th. excubitor Girard is simply the cT ofgiganteus, asthe distinguishing characters of thetwo
supposed species are precisely thesame
asfound in thetwo
sexes of Scorpions.Thelyphonus
has 12 eyes,and
not 8, as hitherto statedby
allauthors,sincethere aretwo
distinct,thoughvery small, accessory ocelli situated on each side near the externo-posterior slope of the ocellar tubercle.No
poison glandscould be detected on the mandible; in factthe onlymeans
of defenceappears tobe avery strongand penetrating odor, butthe position of the odor- iferousglands could not be ascertainedfrom
an examinationof dried specimens.In
commenting on
this paperMr. Pergande
gave the following statementas tothe habits of a specimen ofThelyphonus
sent to Dr. Riley, and keptalive forsome
