A short time ago, in the course of
classifying the Tachinidae in 111y col-
lection, I referred one of the species to Acroglossa hespe7,idaritm Will., since
it agreed in every particular with the
description of this genus and species in Scndder's lGB~~tterflies of New Eng-
land," pp. 1916.1917, with the single
exception that the anterior pair of ocel- lar bristles curved backwad, instead of
for&ard, as stated in the description-
a discrepancy which I imputed to a
typographical or clerical error. The
species also agreed so well with the
descriptions of the genus Spallanzania
Desv. as given by various European
authors that I accepted the statement
orl3rauer and Bergenstamm, based upon
a study of North and South American
specimens, that the genus Acroglossa
Williston is ide~~ticiil with the previ- ousk described Spallanzania Desvoidy
(not Rondani, to whom these authors
erroneously crciiit it; Zweif. Kais.
Museums Wien, V, 354). Nut long
af~er this I received a copy of a paper
by Giglio-Tos, on the ti Ditte~i del
Messico, paste ITJ." wherein this
author refers a Mexican species to
Acroglossa (1. c., 3 j), stating that tl:e sitter genus cannoi: be the same as
Spallanzania, owing to the fact that the ocellar bristles cun-e fo7-wa7-ii - an
opinion reiterated by Mr. W. A. Snow
in the Kans, Univ. Qua~terl~, I1 r, 185. Neither of these authors had se~n the
types of ACI-oglossa, which :ire con-
tained in the Harris collection, now in
the Boston Museum. Wishing to settle
this matter defiiiikly I applied to the
Secretary, Mr. Samuel Henshaw, who
kindly examined these types for me and
writes that the bristles in question
cztrve backwad. My supposition of
an error in the original descriptioni
therefore, proves to be correct, and
there is no valid reason for not sinking Acroglossa as a synonym of Spallan-
zania.
It is interesting to

the types of Pseudogkia ruficanda
Town. and fJ. obsoleta Towns., and
reiiched the conclusion that they sill
belong to one and the same species
(1. c , 184). The descriptions leave no
doubt that this is the true Acr~g/ossa
hes$eridarztni Will.
Brauer and itesgenstaniin refer Cne-
phalia Rond., Pseudogonia B. B. :ind
Spallanzania Desv. as s-ub-genera of
one genus, to which they erroneously
apply the name of Cnephaliii (I. c.,
VI, 214) ; whereas Spallanzaniii is
much the older name. Owing- to the
fact that in certain species of this genus the third antcnn.11 and srcond aristal

joints vary in the different specimens of the s.ime species even to a greater
degree than the above authors state
exists between Cnephalia and Spallan-
zania, the former cannot be maintained
even in the sense of a sub-genus, but
must be considered a synonym of
Spallanzania.
The species referred to above as
laving been assigned to Acroglossa by
Giglio-Tos, is evidently the form pre-
viously described by Van der Wulp as
Pros$herysa vills (Biol. Cent. Am.,
Diptera, II,121), which Brauer and
Bergenstamm make the type of their

WOOLLY LEAF-GALL MADE BY A SPECIES OF CALLIRHYTIS ON SCRUB OAK.
BY C. H. TYLER TOWNSEND, BROWNSVILLE, TEX. In the Can. Ed., 1892, p. 200, I
mentioned the breeding of a hymen-
opteron, determined by Dr. Riley as
Andn'cus sp. (?) from a woolly leaf-
pill on scrub oak, found in the Organ
Mts., Donna Ana Co., N. M.
On Nov. 12, 1892, this gall was
found on scrub oak well up in the
Organ Mts., above the Modoc vine.
Sections that were opened on this date
contained pupae. The galls were also
noticed same date on scrub oaks at the
base of the same mountains, at Riley's
water.
On March 16, 1893, there were found
issued and dead, from (rails collected
Nov. 12. 1892, eleven gall-flies of a
beautiful metallic green color. This is
the above species. There was also
found one specimen, larger in size and
of a flavous brown color, apparently dif- ferent, v\hicli had issued with the rest. The gall m:iy be described as
follows :-
(-rail.-Diameter, about 12 to 15 mm.;
greatest height, 8 to g min.
On under side
of leaf, woolly s~ibhemispherical or dome- shaped in form, attached to the leaf by
small rootlets or stems on the basal flattened surface, 3 stein to each principal section of the gall. Color, pink externally, shaded to slightly brownish or yellowish in mature or
