22 ROBERT NEWSTEAD—A REVISION OF THE TSETSE-F LIES (GLOSSINA), 
gradually attenuated and falciform; bristles very long on both sides, and the 
pubescence extending to the dark chitinous portion near the apex. Inferior claspers 
(tc) relatively very small, and narrowly rounded apically ; they are also placed 
much nearer the articulation of the hypopygium, and as seen in the dorso-ventral 
position (fig. 8, %c) the tips overlap so that a dark ovoid area is presented ; 
bristles long and slender, extending considerably into the broadly dilated or 
proximal portion. Harpes (4) with the larger process broadly bilobed and 
completely covered with large squamose spines. 
Unfortunately the only two preparations in our possession are mounted so as 
to give a dorso-ventral view, and in this position it is impossible to give further 
details of the other morphological characters. Be this as it may, the species is 
markedly distinct from the other tsetse-flies belonging to this group, and, apart 
from the spotted character of the thorax, the males of Glossina longipennis may 
be easily distinguished by the curious squamiform harpes, and the position of the 
relatively small and overlapping inferior claspers. So soon as fresh material 
comes to hand further details will be given, together with drawings of the 
armature in profile, so that they may be compared with those of the other 
members of the fusca group. 
Glossina maculata, Newstead. 
The type and only known example of this insect is unfortunately a female ; 
otherwise I would sacrifice it so that its specific identity could be more definitely 
established. It is nearly related to Glossina palpalis, but in its colour and 
pattern is so markedly distinct as to be recognised from the latter without any 
difficulty. It has been suggested that the characteristic dusky spots are due to 
secretion from other flies which were enclosed in the same packet. This inter- 
pretation I cannot accept, as the spots are not due to any such foreign matter. 
Glossina palpalis, Rob.-Desv. 
Genital armature of the male (fig. 9). Superior claspers (sc) widely separated 
and connected by a membrane (cm); distal extremity suddenly attenuated and 
tooth-like ; there are numerous long bristles on both sides of each clasper, but 
those on the inner lateral margin gradually shorten towards the apex ; there is 
usually one rather long bristle near the base of the tooth-like projection. 
Connecting membrane (cm) deeply divided centrally, and not nearly reaching the 
tips of the claspers; it is partly covered on both sides by minute spines. 
Editum (e), or lappet-like extension of the body wall, with relatively short 
bristles, the longest of which extends midway between the edge of the editum 
and the juxta. Inferior claspers (ic) broad and spinose basally ; apices greatly 
extended, the extension taking the form of a long leg-like process with a 
suddenly dilated extremity, shaped somewhat like a human foot, and furnished 
with a few minute spines along its lateral margin ; these appendages are deeply 
folded basally (not shown in figure), and on either side is a relatively large 
beak-like extension, often apparently a folded extension of the clasper. Harpes 
(h) represented by minute narrow curved strips of chitin which curve upwards so 
that the ends in some instances almost touch the lobe-like extensions of the
