Mr. Schwarz
broughthome from Cuba some
larvae of this speciesin alcohol,and
threemoths
thathehad
bred.He
foundthem
toward theendofDecember on
acultivated plant, Otaheite gooseberry ( Cicca disticha), atCayamas, Cuba. They had
defoliated the plant
and
ate large patches of the barkbesides.Mr.
Schwarz
fed the larvae thathe bredon
the barkas therewere no more

threemoths

records an experi ence similarto thatofMr. Schwarz
of the larvae eating the bark.I^at'va. Head rounded,full, narrowed a little above, slightly bilobed, broad; bright red,labrum paleyellow,jaws andocelli black. Bodyuni form, not elongate, equal,centralsegments aboutaslongas wide,abdom

I proposed thisgeneric term in 1897for theCochlidian species argentijlua
Geyer and argyrorrhea
Hiibner, but gave no exact characters. I havenow
beforeme two male
specimensofargen- tiflua fromCayamas
(E.A. Schwarz), and
Santiago,Cuba
(Capt.
Wirt
Robinson),and
givefrom them
the generic characters. In Ent.
Cubana,
p. 274,Gundlach
refers to this species*Reportof Entomologist andBotanist,from Ann. Kept. Experimental Farms (Canada), foryear1890, pp, 154-188.

under the genus Euproctis, though he evidently recognized it
was
not a Liparid but a Cochlidian.He
brieflymentions the larvaas whitish green, furnished withfleshyprolongations.Ob
viously it resembles the larvae of
Alarodia and
Isochcetes aswould
beexpected.$
antennae bipectinated to the tip, the pectinations decreasing out wardly; head subprominent, palpi curved, slender, just to the frontal tuft; front trigonate,narrowed below,smooth with theerecthairsoftuft centrally. Legslong, hairy; fourspurs. Fore wings with costastraight, veins 2 and 3 separate,cell with short-forked open discal vein, 7 from apex ofcell, 8 to 10stalked; hind wings with 6and 7at apexofcell, 8 anastomosingatbase.Form

Caudell exhibited a livingmale
specimen of the rare cockroachTemnopteryx
deropeltiformis Brunner.He
reared thisroach from a larva taken lastfall at FallsChurch,
Virginia.There
areknown
tohim
buttwo
other instances of the capture ofthisspecies eastofIndiana a(j> taken
by Mr. Jacob
Kotinskyat
Washington, D.
C.,two
years ago, and another ? takenby Mr. Nathan Banks
at FallsChurch,
Virginia, one year later.Wasmann*
records thisas amyrmecophilous
insect, hisrecord being based on specimenssenthim by Mr.
T.Pergande and
col lectedunderstonesatCabin John
Bridge,Maryland.Not
long agoMr.
Caudell visited this locality withMr. Pergande and
under stones in exactly similar situationsfound specimenswhich Mr.
Pergande pronounced
thesame
asthose senttoWasmann. These were nymphs
and,on
maturing, proved tobe Ischnoptera uhler-iana
Saussure.Mr.
Caudell stated that he had no doubt that the specimens sentWasmann
are this species and notTemnop
teryx.
The
specimens of T. deropeltiformiswere
taken in decayingwood, and Mr.
Caudell said he did not believe thatTemnopteryx had
been found in ants' nests.He added
that there are, in the NationalMuseum,
specimens of thisspecies from Texas.Mr.
Caudell mentioned, also, another cockroachnew
