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 Bahos, 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 antennae, 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 scutelium. 

 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; scutelium 

 as in the preceding species. Chastotaxy 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.
