614 Prof. Mario Bezzi's Report on a Collection of 
species are certainly different, that of 1860 must be 
re-named Lomatia lvewi, nom. nov. 
The single specimen in the collection, taken at 
Vitiya, West Nyasa, October 1910 (Dr. H. S. Stannus), 
seems to belong to the species of 1854; but the deter- 
mination is very doubtful. The indentation of the hind 
margin of the eyes is very obsolete. 
15. Lomatia gigantea, sp. nov. (Plate L, fig. 2.) 
¢. Length of the body 15 mm., of the wing 17 mm.; wing- 
expanse 37 mm. General appearance as in our species of the group 
of L. belzebul. Belongs to Division I B of Loew, near L. picti- 
pennis, Wied., but of much larger size and with very different 
wing-markings. The size is about the same as that of L. lungi- 
tudinalis, Loew, which has, however, yellow legs. 
Ground colour of head, body, antennae and legs black. Occiput 
clothed with grey tomentum and yellow pubescence; face and 
frons with long golden yellow hairs; ocellar tubercle and vertex 
with black hairs. Eyes subcontiguous, with the indentation of 
hind margin broad and distinct. Two first joints of the antennae 
with short black and yellow hairs; third joint elongate conical, 
a little excavated below, gradually tapering into a long style. 
Proboscis black, as long as the head. Thorax on dorsum clothed 
with olive-brown tomentum, which is grey on the pleurae and 
below; the hairs are dense and golden yellow, greyish on the 
pleurae, with whitish tufts on meso- and sterno-pleura ; the bristles 
are yellow. Squamae pale yellowish with white fringe; halteres 
yellowish. Abdomen with entire transverse bands of golden 
tomentum at the hind margin of each segment; first segment 
clothed with long hairs, which are yellow dorsally and white 
ventrally ; the hairs on the sides of the other segments are also 
long and paler; underside with short grey pubescence. Genitalia 
not prominent, dark reddish, black above, shining. Legs with 
golden yellow pubescence and black bristles ; on the four anterior 
tibiae the pubescence is whitish. Wings very long; the markings 
about as in L. pictipennis, but the colour yellowish and not brown ; 
there is a dark marking along the first basal cell and around the 
small cross-vein and its vicinity ; on the marginal, submarginal and 
discoidal (including the second basal) cells are longitudinal stripes 
of a pale yellowish tinge. No distinct pre-apical brown band ; the 
hind margin of the wing is hyaline throughout its whole length, 
as is also the apex. Direction of wing veins as in Loew's pl. II, 
fig. 12, but the first posterior cell is not so narrowed at its end. 
Type ¢, from Nyasaland, Blantyre, May 3, 1910 (Dr. 
J. E. S. Old); a single specimen.
