The ovipositor of the female is black and shilling- and arm^d at tip 

 of so<;inents M'ith a few scatteriiij>- reddish liairs (see Fig. 51 a, b). The 

 wings are sliglitly 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 Uneata, I have thought 

 it well to reproduce the figures of H. hovis, published in Vol. ii of 

 Insect Life, with some few descriptive notes as to the mature fiy, 

 especially as there are some errors in the descriptions of these figures 

 in the previous article.* 



The differences between the 

 larva? have already been i)ointed 

 out, and the e^xg 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 Uneata. The perfect fly 

 in Jtovis is a much larger, stouter 

 insect than in Uneata, being 

 fully twice the size in hulk. 

 Exclusive of the ovii)ositor, it 

 measures five-eighths of an 

 inch, and the general distribu- 

 tion in color of the hairs cloth

 dorsal view; c, i>ii|)ariiiia, dorsal view; e, d, anal stig- 

 mata of larva; one of same still more enlarged — all en- 

 larged (after Brauer). 



iug the body is similar to that of Uneata, 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 figiue copied from Brauer 

 (Fig. .")3). The legs are comi)aratively 

 stouter, and the hair coveiing the basal 

 Fig. 53.-/7j,pod«r»,a «;o«;*-eniarged (af. joiuts, including the fcmora, is compara- 

 ter Brauer). tivcly sliortcr and less dense than in Une- 



ata. The wings also are somewhat ligliter colored, with the veins red- 

 dish or reddish brown. 



' By oversight, Fig. 33rf, Insect Life, Vol. ii, 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. 17.5, ihid., was that of Ili/poderma lineala, and not of hovis, as 

 stated.
