284 ERNEST E. AUSTEN—-NEW AFRICAN 
District, Northern Rhodesia, 1911 (2. A. Copeman); 1 Q from Kilima-Njaro, 
German East Africa, 1887 (F. J. Jackson, C.B., C.M.G.), Tn addition to the 
foregoing, all of which are in the National Collection, the following three 
specimens from the Nyasaland Protectorate (S. A. Neave), which are in 
the possession of the Entomological Research Committee, have also 
been examined:—1 Q from the Upper Shire Valley, February, 1910; 
l Q from Fort Johnston, February, 1910; and 1 Q from the south-west shore 
of Lake Nyasa, March, 1910. 
From Tubanus claritibialis, Ric., to which, as mentioned at the commencement 
of the diagnosis printed in italics above, the new species is closely allied, 
T’. pullulus is distinguishable by the abdomen—instead of being (except at tie 
distal extremity) cinnamon-rufous and clothed above exclusively with black 
hair—being entirely dark, and clothed on the dorsum, at least in part, with 
minute, appressed, glistening, ochreous hairs. As regards external morphological 
characters, the only noticeable difference exhibited by 7. pullulus as compared 
with 7. claritébialis is to be found in the greater length of the annulate portion 
of the third antennal joint. 
Tabanus crocodilinus, sp. n. 
©.—Length (18 specimens) 9°6 to 12 mm.; width of head 3°5 to 4*4 mm. ; 
width of front at vertex 0°6 mm. to just under 1 mm.; length of wing 8 to 
975 mm. 
Small, compactly built, dusky species, with rather broad head (which, viewed from 
above, is regularly convex in front and noticeably concave behind), a sharply defined 
and conspicuous, clove-brown frontal callus, which does not send off any hind of 
prolongation above, and with characteristically spotted abdomen.—Dorsum of thorax 
blackish slate-coloured, clothed with short, appressed, tawny-ochraceous hair, mixed 
with fine, erect, blackish hairs ; dorsum of abdomen clove-brown, with a double 
series of transversely elliptical-oval or nearly circular, light-grey spots. 
Head; front, from a little way above callus to vertex, mouse-grey, brownish 
grey, or brownish, clothed with very short, dusky or blackish hair; front 
immediately above callus yellowish grey on each side, and clothed with minute 
ochreous hairs ; sub-callus drab-grey or smoke-grey ; face, jowls, and basiocci- 
pital region whitish grey and clothed with white hair ; occiput light grey ; front 
of moderate breadth above, narrower below ; frontal callus normally quadrate, 
with its upper angles rounded-off, narrowly separated from eye on each side, in 
rubbed specimens sometimes somewhat more elongate ; palp? small, pale cream- 
coloured, clothed on outer side with white hair, mixed in case of terminal joint 
with minute black hairs, terminal joint viewed from side broad at base and 
abruptly tapering to a point ; antennae small, first and second joints cream-buff 
or buff, clothed above with minute black hairs mixed with glistening silvery 
hairs, third joint entirely ochraceous-rufous or ochraceous-buff, its expanded 
portion of moderate breadth, and the angle on its upper margin usually neither 
sharp nor prominent. Thorax: dorsum not striped, though the beginnings of 
three narrow grey stripes can sometimes be seen next front margin; a few 
whitish hairs on postalar calli, and above base of each wing ; swelling occupying
