most remarkable. The worker

I

conclude

that

aprica and _biplaga

^arevarieties of

one

_species,

although Smith has recorded

the contraryopinion.*

Indeed

a series of

40 specimens

^before

me shows

the

two forms

to inter- grade.

One

of the

specimens from Texas (form aprica} has only

^{a little of the}

dark

color left

on

thevertex of

head and

thus closely

approaches

^{the local} race ceyvestensis.

Oncocnemis

laticosta, ^n. sp.

Thorax

abdomen

_{light. Fore wings pale} ocherous in ground color, the inner two-thirds of

wing

heavily overlaid with ^blackish,

pow

dery, not obscuring ^{the marks.} Lines as in

lalutea Smith, black, edged ^with pal?, crenulate; basal line obsolete, t.-a. slightly arcuate, t.-p. bent outbeyond^cellwith white points onveins2and_4. Terminal space dark shaded, enclosing thepale,broken, irregular subterminal ^line.

Ordinaryspotspaleocherous,filledby^adarker shade; orbicular elongate, claviform punctiform, nearly^obsolete.

Ten _specimens, Nogales and Huachuca

The Nogales specimens

^{all lack the}

black

longitudinal stripe,

while

the others all

have

it. I

do

not think this

more than

varietal.

Mr. Schaus mentions

its

presence

^or

absence

in his description.

Pseudhapigia brunnea ^Schaus.

Four _specimens from Mr.

_Oslar,

taken

in

Nogales and Tucson, Arizona. Only two

species are

known

^{in this}

_genus, and

^it

may

be

thatthe

form

^before

me

is

new,

^{as it}

^does

^not tally in all respects

with

the descriptions ^of

brunnea Schaus

^or xolotl

Schaus. But

Family MEGALOPYGID^.

Archylus ^{tener Druce.}

Mr. E.

_J.

Oslar has

sent

me

a c?

specimen, taken

ⁱⁿ

southern Arizona.

It _is, apparently, referable to the

Megalopygidae, though

the structure is

unusual

asthere is

no branch

to vein i

on

the fore

wings, while

^veins 7

and

8 of

hind wings

^areunited

to well

beyond

^the

^end

^{of the} cell, arising

from

a stalk

from

its

upper

angle.

The _appearance

of the insect is well

shown

inthe .rigure in the Biologia Central!-

Americana,

pi. 79, ^{fig. 6.}

It

may ^remain

^forthe present ⁱⁿ the

genus Archylus Walker, though

^not

agreeing

entirely.

The _type

of

Archylus

^is

gutti- fascia Walker, ^which,

^{as Sir}

G. F. Hampson

kindly

informs me,

^{is a}

Megalopygid much

like tener, but vein 8 of the

hind wings

^arises just before

angle

^{of thecell}

while

the cell is short.

These

differences are

probably

^of generic value,

but

^I will

only

call attentionto

them now.
