NOTES ON THE LIFE-HABITS

OF ^EGERIID.E.-

A

specimenof Melittia gloriosa Hy. Edw., from San Diego,Cal.,the food-habits of which, so far asIknow,are not jet recorded, though the

moth

itselfhas been found flyingaround cucurbitaceous plantsby Mr. Edwards, and \\ wasnaturally inferred that the larva

might

live, like its congener,

M.

cucurbitce, inthe roots of these plants. This species, however, was reared by Mr. F. E.

Blasedalefromthe rootsof RJnis laurina.

The

pupal

exuvium

showsthat the spines are

more

strongly

marked

than in any other ^Egerian with whichI

am

acquainted, thefrontal thornsbeing noticeably strong,and re- callingthe

same

parts in the largerAsilidceandAnthracidce.

sEgeria impropria Hy.

Edw.

(specimens of imago, larvaand pupa) is injurious, in the larval state, to strawberries in southern California. I

have, for

some

years,

known

of great injurytostrawberryrootsby

some

borer ofaLepidopterouscharacter, but thespecies had remained undeter- mined, as I had been unable to obtain specimens.

As

soonasIhad an opportunity ofexamining

some

strawberry plants on the plantation of Mr.I.V.Wilcox,ofSantaClara,Cal.,itwasevidentthatthelarvabelonged tothe;3Lgeriidce.

The

larva of impropria has been hitherto

unknown

andthe

name maybe

said, paradoxically, tobequiteproper,andyetquite improper; forMr.

Edwards

had alsodescribed a speciesofsEgcria bythe

name

offragarice, thelarvaofwhich was not yet

known,

though Mr. Ed- wardsinforms

me

that it

was

found on the flowers of strawberry.

Phemonoe

who

The imago

from southern California, rearedfrom larvaeboring underthebark of Salix californica.

An

known;

so that the species occurs on bothcoasts.

COLOR-VARIATION

IN

THE LARVA

OF

AGRAULIS VANILLA.

Iwouldalso callattention toan interesting variation whichI noticed at

Los

Angeles inthe coloration of thelarvaofAgraulis vanillce.

The

eastern form of this larvaisgenerally reddish orvinous-brown in color, with an indica- tionoftwodarker longitudinalrays, as

my

notesand preservedmaterial,

andthefiguresby Smith and Abbott and the older authorsshow.

Those

foundat

Los

Angeles were very striking by virtue of the general color beingofabright leaden-blue or pale indigo-blue,withabroadbrightlat- eral cream-coloredstripe

more

or less diversified with ferruginous, the headdistinctly

marked

with vertical palevittseandwithapale crown.
