by Dr. W. E. Britton (19th An. Rept. Conn. Agr. Expt, Sta. for 1895 
[1896], p. 204). He mentions it as a leaf -miner of the cauliflower, and 
states that some plants growing' in the shade were seriously injured, 
while others finally died. 
In looking through the material in the National Museum references 
have been obtained to rearings of this species which have evidently 
never been made public. Adults were reared September 9, 1885, from 
"bolls" of horse-nettle (Solcmum carolinense) — no locality given, but 
with little doubt the District of Columbia or vicinity. July 15, 1894, 
the flies were reared from Iceland poppy {Pcqxiver medicinale) received 
from Mrs. Celia Thaxter, Appledon, Isle of Shoals, off Portsmouth, 
N. H. ; and April 21, 1900, flies were again reared, from the District 
of Columbia, from larvae mining the leaves of mouse-ear or thale-cress 
(Stenophragma thaliana), a cruciferous plant naturalized from Europe. 
The Native Cabbage Leaf-miner (Scwptomyza ackis ta Loew.). — This was 
reared with the preceding from the same locality, adults issuing from 
December 22 to 28. They outnumbered the preceding species three 
to one, and it is not improbable that this is the most abundant form 
of dipterous leaf-miner attacking cruciferous crops in the South. AVe 
have an earlier record of the rearing of this same species from a growth 
resembling a gall or fungus on the stems of water lilies, obtained by 
Mr. Albert Koebele in Virginia, near the District of Columbia, August 
21, 1883. The flies issued September 8, and four days later a different 
species was reared. a 
We have no very complete knowledge of this insect's distribution. 
It occurs, however, from Maine to Florida, and westward as far as 
Illinois. From specimens in the Nutional Museum we have the fol- 
lowing localities; Eastport, Me. ; Washington, D. C. ; Virginia; Bis- 
cay ne Bay ,Fla. ; Augusta, Ga. ; Algonquin, 111. The insect was described 
from the United States, and is evidently indigenous to our soil. 
The Imported Cabbage Leaf-miner (Scaptomyza gra?ninwm Fallen). — 
This was reared December 22, 1898, from leaves of cabbage received 
from Augusta, Ga. This is the second rearing of the species from 
cabbage, the first having been made by Dr. A. D. Hopkins in West 
Virginia. It is probable that in time this miner will be found to 
develop in many other plants, since in Europe it is known to attack 
chickweed, cockle, lamb's quarters, and two genera of catchfly or cam- 
pian (Viscaria and Silene). 
April 5, 1902, Prof. H. A. Morgan, Baton Rouge, La., sent speci- 
mens in all stages, with the statement that this species was found with 
the corn stalk-borer in sugar cane in that vicinity, and the larvae were 
confused with the young of the true borer. 
In Europe this species is common and widespread, and the same 
is true of its distribution in this country, although it appears to be 
:i This was determined by Mr. Coquilleti as Crassiseta nigriceps Loew.
