BASED ON A STUDY OF THE MALE GENITAL ARMATURE. 15 
Small and slenderly built. Abdomen pale, with distinct transverse blackish 
bands ; median pale stripe very distinct. Legs with the exception of the 
hind tarsi and the tips of the front and middle ones, pale yellowish. 
Inferior claspers of male with a very short stem to the foot-like terminal 
process ; superior claspers as in 6. 8. tachinoides, Westw., p. 25. 
Small and stoutly built. Abdomen as in 6, but with the usual transverse 
dark bands more evident. Thorax dusky grey with four greyish-black, 
triangular, blotches. Legs almost uniformly infuscated. Superior claspers 
of male curved and terminating in a claw-like point. 
9. fuscipes, Newst., p. 26. 
Abdomen almost unicolorous, but darkening gradually towards the margins 
and posteriorly. Superior claspers of male straight and gradually 
narrowed, truncate and spinose at the apex. 10. pallicera, Big., p. 27. 
Group III. (Morsitans Group). Tips of hind tarsi only dark or black (A); or 
with the tips of all the tarsi dark or black (B). Length 72-10 mm. 
A. Both sexes with the front and middle tarsi yellow. Third segment of 
antennae long and narrow, apex pointed. Superior claspers in male 
very similar to those of 12, with a large flange-like projection 
internally, the breadth of which is greater than the width of the stem 
of the clasper at the point of its origin. 
11. pallidipes, Aust., p. 30. 
B. Tips of all the tarsi dark or black. 
Abdomen often with a large dusky red-brown area; transverse bands 
on third segment may be either widely separated and faintly indicated 
medially, or strongly pronounced and narrowly separated. Superior 
claspers in male terminating in a large tooth-like process on outer 
angles, the internal flange-like projection much narrower than stem 
of clasper, and not produced distally into a median lobe. 
3 12. longipalpis, Wied., p. 29. 
Abdomen with the median stripe usually much wider on the third 
segment than on the fifth. Median lobes of the superior claspers in 
male converging distally ; outer angle of claspers without any tooth- 
like process. 13. morsitans, Westw., p. 32. 
Abdomen with the transverse bands sharply defined medially, median 
stripe usually of uniform width on the third fourth and fifth segment. 
Median lobes of the superior claspers parallel; outer angle of 
claspers without any tooth-like process.

Genital armature of the male (figs. 3 and 4). Superior claspers (sc) very 
widely separated (dorso-ventral view, fig. 4) ; suddenly rounded apically on the 
outer lateral margin, the inner lateral margin produced and forming a stout 
tooth-like projection. When mounted so that an oblique lateral view is obtained 
the tips sometimes appear to be bluntly bidentate (fig. 3); but the true form of 
these appendages is that which is shown in fig. 4. Mach clasper is clothed 
dorsally with fine pubescent hairs, and also with a number of very long bristles. 
The editum, or lappet-like extension of the body wall, is broad and bears a
