The ovipositor of the female is black and shining and armed at tip 
of segments with a few scattering reddish hairs (see Fig.51 a,b). The 
wings are slightly and uniformly dusky, with the veins dark brown. 
The surface is finely striate or wrinkled. 
COMPARISONS WITH HYPODERMA BOVIS. 
In connection with this account of Hypoderma lineata, I have thought 
it well to reproduce the figures of H. bovis, published in Vol. 11 of 
INSECT LIFE, with some few descriptive notes as to the mature fly, 
especially as there are some errors in the descriptions of these figures 
in the previous article.* 
The differences between the 
larve have already been pointed 
cut, and the egg of bovis, which 
I have not seen, but the figure 
of which (Fig. 52a) is copied 
from Brauer, is evidently of 
very much the same nature as 
that of lineata. The perfect fly 
in bovis is amuch larger, stouter 
insect than in lineata, being 
fully twice the size in bulk. 
Exclusive of the ovipositor, it W se 
measures five-eighths of an Fig. Oa LUDO Cena bovis: a, egg; b, fall grow larva, 
dorsal view; c, puparium, dorsal view; e, d, anal stig- 
inch, and the general distribu- mata of larva; one of same still more enlarged—all en- 
tion in color of the hairs cloth- '"se¢ (after Brauer). 
ing the body is similar to that of lineata, except that the light hairs of 
the head, thorax, and basal segments of 
the abdomen are of a darker lemon yel- 
low. These yellow hairs cover definitely 
the anterior half of the thorax, not inter- 
mixed with black, while the central tho- 
racic region is smooth, more shining, and 
is without the light-colored hairs, as indi- 
cated in the figure copied from Brauer 
(Fig. 53). The legs are comparatively 
stouter, and the hair covering the basal 
joints, including the femora, is compara-

Fig. 53.—Hypoderma bovis—enlarged (at- 
ter Brauer). tively shorter and less dense than in line- 
ata. The wings also are somewhat lighter colored, with the veins red- 
dish or reddish brown. 
* By oversight, Fig. 33d, INsecr Lire, Vol. u, was described as the newly-hatched 
larva, whereas it is the enlarged spiracle of the mature larva. So also the ovipositor, 
shown at Fig. 35, p. 175, ibid., was that of Hypoderma lineata, and not of bovis, as 
stated.
