New Lepidoptera from Dutch New Guinea. 381 



wing. Forewing with a faint dark sub-basal line, more distinct on 

 costa, crossing cell just below vein 2 and in line with this vein, then 

 vertically to inner margin. A second line parallel to it, crossing 

 cell below vein 3. An oval black discocellular spot. Beyond cell 

 an oblique dirty-white line at a J from the margin, edged with 

 black distally. A little beyond is a curved row of black vein dots 

 which form the inner border of a pale submarginal band. Hind- 

 wing paler costally. A black spot in middle of cell and one at end 

 at upper angle. Post-discal line nearer cell than it is on forewing. 

 Two specimens obtained. 



35. Euproctis pratti albonotata, subsp. nov. 

 (Plate LXI, fig. 10.) 



(J. Differs from pratti, B.-B.,* in the purer white of the sub- 

 marginal and apical spots on forewing, and the more elongate 

 apical spots, the one on vein 7 being longest. The pointed distal 

 ends of the spots touch the margin. The round spot at end of cell 

 is snow-white, smaller than in the type form, and unlike that it 

 does not extend into cell below vein 3. The veins are more strongly 

 outlined with whitish scaling. Hindwing paler than in pratti and 

 the veins whitish at their ends. 



Underside paler than in the allied form and white spots well 

 marked. Hindwing with veins whitish. 



Length of forewing : 22 mm. 



4 (^ <J were obtained. 



36. Euproctis seminigra, sp. nov. ' 



(Plate LXI, fig. 11, c^.) 



cj. Upperside. Forewing with grey-white ground-colour. Base 

 black with a convex outer edge. A dark post-discal band from costa 

 to inner margin and not entering cell, proximally and posteriorly 

 diffuse, and in cellules 3 and 4 joined to a darker marginal border. 

 All veins grey-white. Hindwing smoky black; fringe white from 

 anal angle to vein 4. 



Underside. Forewing with base and a large apical area smoky - 

 brown, traversed by the white veins ; remainder grey-white washed 

 proximally with pale yellow. Hindwing as above, veins whitish. 



Head, antennae, thorax, pectus, and legs smoky-brown. Patagia 

 fringed with yellowish hair. Abdomen black, anal segment fringed 

 with grey-white hair, anal tuft smoky-brown. 



$ like the <^, but with post-discal band on forewing better defined. 



Length of forewing : ^ 24 mm., $ 31 mm.
