yellowish-white, with a black spot on the top of its head, which is 
continued backward to the pedicel of the neck. Thorax with three 
broad black stripes, approaching each other anteriorly but not com- 
ing in contact, the middle stripe prolonged anteriorly to the pedicel 
of the neck and posteriorly to the apex of the scutel. Abdomen with 
three broad blackish stripes, which are confluent posteriorly and 
interrupted at each of the sutures. Tips of the feet and veins of 
the hyaline wings blackish. Eyes bright green. Antenne dusky on 
their upper side.”’* 
Next,. in 1869, Prof. Riley published, first in the ‘“‘Rural New 
Yorker” for January 28, and afterwards in his first report as State 
Entomologist of Missouri, an article on this imsect, giving in the 
latter publication a figure and description of the adult fly, and 
rather rude and inaccurate figures of the larva and pupa, together 
with an illustration of the character of the injury to wheat. 
He notes the general prevalence of the insect in wheat fields near 
St. Louis, and suggests hand-picking and rotation of crops as 
remedial measures. Prof. Riley also gives Baron Osten-Sacken as 
authority for the specific determination of his specimens. 
The species was again noticed in New York in 1879, specimens 
having been submitted to Prof. Lintner, who reported on them in 
the ‘‘Country Gentleman” for that year (p. 535); in the thirty-ninth 
annual report of the New York State Agricultural Society for 1879 
(pp. 42-46); and again in his first report as State Entomologist of 
New York for the year 1881 (pp. 221-227). These several articles 
differ but tittle, and consist essentially of a summary of the obser- 
vations of Fitch and Riley, with some additional notes on the char- 
acter of the injury, dates of transformation, and the general 
appearance of larva and pupa. 
Prof. Lintner’s descriptive remarks are as follows: ‘Immediately 
above the joint, and surrounded by the remains of the stem, 
larve were discovered, a single one in each stem, of a watery- 
ereen color, elongate, quite tapering toward the terminal end, and 
subcylindrical at the other, and of a length of about one-fourth of 
an inch. In some of the stems larve had assumed the pupal 
stage, not very unlike the larve in general appearance, but show- 
ing the wing-cases, a more acute form at its head, and more 
rounded at its anal extremity. The pupx were also imbedded 
within the remains of the stem, at about the distance of half an 
inch from the joint.” 
In an addendum to his report (p. 844), Prof. Lintner further remarks : 
“When the examples of the transformed larve referred to came 
under my observation, the external features of the pupa were so 
well defined that, not being reminded at the time of its necessarily 
coarctate form, the puparium was not noticed. My attention having 
recently been called to this feature of the insect by an inquiry of 
*[This description is inaccurate in some particulars, and a fuller one will be given on 
another page. The general color is green and not yellow in every specimen I have seen, 
and the thoracic stripes are often confluent anteriorly.
