22. Mellesis nummularia Bezzi. Plate II, fig. 6. 
Mellesis nummularia Bezzi, Bull. Ent. Research 7 (1916) 115. 
Allied to the preceding species, but distinct by the paler 
coloration of the body and of the legs, as well as by the richer 
wing pattern, which has a broad, rounded, apical, dark brown 
patch. 
Luzon, Laguna Province, Los Banos, Mount Maquiling and 
Mount Banahao {Baker). Types in Professor Baker’s col- 
lection. 
Male and female . — Length of body, 8 to 8.5 millimeters; of 
wing, 7 to 7.5; of antenna, more than 2; of ovipositor, 1.5. 
Head and its appendages as in the preceding species; but oc- 
ciput reddish, with a narrow yellow border, frons less distinctly 
yellow on sides, with a black ocellar dot, a reddish brown ver- 
tical stripe, and the middle transverse spot less developed ; face 
without black spot just below root of antenme, and with two 
broad rounded black spots, one on each side toward middle of 
antennal grooves; antennae paler, third joint being only in part 
infuscated ; two pairs of lower orbital bristles thinner, but 
always well developed. 
Mesonotum as in the preceding and with the same yellow 
markings; but prevalently reddish on back, the black pattern 
being reduced to a narrow, middle, longitudinal stripe, ending 
at suture, and to two small patches, one on each side, near the 
yellow sutural stripe; characteristic for the present species is 
a short yellow middle stripe, which begins acutely just beyond 
suture and ends obtusely midway between suture and scutellum. 
Pleura entirely reddish, with only a small black patch on meso- 
pleuron in front of yellow mesopleural stripe. Mesophragma 
reddish, with blackish sides ; postscutellum reddish ; scutellum 
as in the preceding species. Chsetotaxy the same and bristles 
likewise black. 
Abdomen as in the preceding, but with basal stalk a little 
broader ; second segment more broadly yellowish at hind border, 
and in the middle a short, dark, longitudinal stripe not reaching 
hind border; third segment yellowish in the middle behind, the 
yellow being thus united with the yellowish patches of the last 
two segments, and the middle longitudinal black stripe begin- 
ning with it. Cilia of third segment longer ; ovipositor conical, 
dark reddish. Four anterior femora more or less blackened, 
the posterior ones being quite yellowish and unspotted.
