border, and often coalescing with the discal spot; a third, narrower, but more coin- 
cident with the basal, starting from outer third of costa and reaching outer fourth 
of inner border; a fourth, subterminal, more pale and diffused, anteriorly parallel 
with and close to third, more irregular and jagged postericrly, and the fifth, termi- 
nal and also faint, narrowing toward anal angle and broadening toward costa; all, 
especially 1, 2, and 3, are broadened and intensified on costal and mner borders; 
fringe broad, concolorous, with nine more or less distinct dark spots along base in a 
line with the veins. 
Secondaries.—Slightly paler in color, with four less distinct transverse dark bands; 
the first across basal fourth, the second across middle and involving discal spot, the 
third more diffuse and between it and the terminal and the fourth terminal; the 
basal two darker and narrower than the others; all somewhat intensified and broad- 
ened on the inner border. Fringe marked with dark spots near base and in line 
with the veins. 
Under surface of the wings somewhat darker than upper surface, more uniform 
in shade, with the pattern of the upper surface more faintly discernible except the 
discal spot, which is more intense. 
’ No especial sexual colorational differences, the males being somewhat smaller and 
having rather darker front legs. 
There is some variation, not only in the general color but also in the distinctness 
of the transverse lines. In some of the specimens there are a number of dusky 
scales on the light background between the bands, making these more diffuse; in 
others the bands are very abruptly and distinctly separated from the ground color. 
Egg.—Bluntly ovoid, 0.04 millimetres in length, pale grayish and usually quite 
delicate, but firm enough to retain its shape after hatching, and irregularly reticu- 
late. 
Full-grown larva.—Seven millimetres in length, normal, and possessing but one 
pair of abdominal prolegs, pale olive gray, with medial dorsal and subdorsal darker 
lines; head honey-yellow inclining to brownish; antenne paler and with a few 
pale short fleshy bristles; the whole body is transversely wrinkled on the longer 
and middle segments, showing from six to seven or more of these transverse folds. 
In the dorsal region on each of the anterior and posterior folds are two spatulate 
processes arising from rounded tubercles, while subdorsally and laterally there are 
a series of about four to each segment and subventrally two of these same spatu- 
late processes. On the anal segment these spatulate processes are more numerous 
and close together. : 
Pupa.—The pupa is characterized chiefly by a lateral projection on the fifth 
abdominal joint and by a somewhat brief cremaster with six rather long hooked 
bristles.

UGIMYIA SERICARIZ ROND., THE PARASITE OF THE JAPANESE 
SILKWORM. 
By Prof. JOSEPH Mik, Vienna, Austria.* 
Through the kind intercession of Prof. C. V. Riley, of Washington, I 
received the larva, puparium and one pair of the imago of the Tachinid 
fly which Rondani, without having any knowledge of the imago, had 
named (Boll. Soc. Entom. Ital., T. 0, 1870, p. 137) Ugimyia sericarie. 
* Translated from the German in the Weiner entomologische Zeitung, vol. 1x, No. 
10, December, 1890, pp. 309-316, and published in Insect Lire at the suggestion of 
the author.
