here concerning the other two species referred to,-S. maculz~ennis Scudd. and S. aegiialis Scudd. From my collections gathered dur- ing the last three seasons and notes concern- ing them taken in the field, I am fully con- vinced of the distinctness of these species. S. aequalis I have found one of the most plentiful~locusts in New England, everywhere common on dry soil, and very variously
colored."'With this species I unite S. biz- neatus Scudd.
5. macvl@eftm's on the other hand I have taken only in Southern New England, where I have found it most plentiful near the coast, preferring sandy soils. This species also is very variously colored. Individuals of both species may be wholly either brown or green or any mixture of the two, but green males are the least common of any of the forms and in some7places are exceedingly scarce. Not infrequently specimens show considerable rose-red above or may be very largely black- ish-fuscous throughout.
The structural characters presented by the head, vertex, and pronoturn are the best means of separating these species from each other and from olivaceus, but the length and markings of the tegmina are also helpful. It may be of interest in this connection to stale that I have examined some of the speci- mens collected by Prof. S. I. Smith at Nor- way, Me., and referred to in his paper on the Orthoptera of Maine as S. maculzj+ennis, and also some in the collection of Cornell Univer- sity collected in New York and referred to in Prof. Comstock's Introduction to Entomology under the same name. Allof these I am dis- posed to consider as belonging to aequalis. Some of the Norway, Me., specimens show
an unusual length of wing but assuredly are not maculi-pennis Scudd. I have also exam- ined the types in Mr. Scudder's collection. June 1893.1 PSYCHE. 479
ADDITIONS TO THE LIST OF BOMBYCES AT POUGHKEEPSIE. BY HARRISON G. DYAR, BOSTON, MASS.
In the August, 1891, number of
Psyche I gave a list of the Bombyces
found in Poughkeepsie, N. Y., and in-
cluded four species of Arctia. Further
study has shown that this list must be
increased to seven species. From my
series of A. vwo I have picked out two
specimens which are referable to A.
intermedia Str. They are of the form
in which the markings of the fore wings
are practically as in A. virgo, being
less extensive than in Stretch's figure. This form differs from A. ĺ´parthenic
Kirby only in size, and may prove to be
a southern race of it. Parthenice occurs not rarely at Plattsburgh, N. Y. ; but I have never met with it in Dutchess
County. The f genitalia of these forms
do not differ specifically. I have made
drawings from balsam mounts and
cannot find any differences which are
greater than the range of individual
variation. From the same parts in A.
virgo they differ slightly and probably
to a degree which is specific.
Under the term nais in my list were
included all the forms with the pallern
of marking of that species. I am now
satisfied that we have not two species,
nais and decorata, as they stand in
Professor Smith's list, but three well
defined and distinct species, differing in markings of the moth, in the larva ac-
cording to the observations of Prof. G.
H. French and Mr. J. Doll, and in the
structure of the f genitalia, In another

tions of these species. Here I will give wres
the synonymy, the accompanying fiD
of the genitalia and a table of species. Some of the synonyms given below
may be worthy of varietal rank ; but I
have not access to all the publications
and cannot determine the matter*

tapering posteriorly. . . nais.
B.
Costal edge of primaries yellow, except

red, the black dorsal band tapering pos- teriorly; secondaries rosy red along ab- dominal margin in 3, crimson in $ , the
spots rarely confluent. . fhalerata.

Expanse 38-43 mm.; marks more or
less incomplete, usually markedly so ;

band widened and diffuse posteriorly,

marginal band of confluent black spots.
