instructive figure of the characteristic wing of the present species

111. Scamboneura dotata 0. S. 1882. 



A single female from Mount Maquiling. Endemic. This may 

 be the unknown female of Osten Sacken's species, or a different 

 species. It differs from the description of the male in the fol- 

 lowing points: Frons entirely yellow, without middle brown 

 line; joints of the flagellum entirely blackish ; thorax entirely 

 yellow, opaque, without stripes; scutellum and mesophragma 

 entirely yellow, the latter paler; pleurae entirely pale yellowish. 

 Abdomen yellowish, with a darker, median longitudinal stripe; 

 ovipositor shining reddish, with the terminal lamellae straight 

 and obtuse at end. 



In the Javanese species, S. qiwdrata de Meijere, 1913, of 

 which only the female is known, the thorax has three longitudinal 

 brown stripes; S. vittifrons Walker, 1861, from Amboina, also 

 known only from the female, has an ochraceous unstriped thorax, 

 with two black dots on each side ; in addition, the head, antennae, 

 and abdomen are differently colored. At present I think it 

 better to consider the present specimen as the other sex of 

 dotata, or at most as a variety, which may be named S. dotata 

 unicolor var. nov. 



Key to the Philippine species of the genus Eriocera sens. lat. 



The genus Eriocera seems to be very rich in endemic Philip- 

 pine species; those known to me may be distinguished as 

 follows : 



a 1 . Wings with only four posterior cells (Eriocera sens. str.). 



ft 1 . Antennae of male enormously elongate, many times as long as the 

 body; wings subhyaline in both sexes, with the anterior and poste- 

 rior cross veins placed on the same line with the basal vein of the 



discoidal cell verticalis Wied. 



6 2 . Antennas of male much shorter than the body; wings in both sexes 

 infuscated with a whitish middle spot and with the above-named 

 veins not in the same line. 



c\ Hind legs of the usual shape; abdomen dilated, shining, with viola- 

 ceous reflections and with some yellowish bands near the base. 



lativentris sp. nov. 

 c 2 . Hind legs distinctly thickened; abdomen not dilated and entirely 



black crassipes sp. nov. 



a 2 . Wings with five posterior cells (genus Physecrania Big.). 



ef. Legs black; abdomen with one or two yellow crossbands near the 



base; wings with black base and fore border mansueta O. S. 



eT. Legs yellow, with black knees; abdomen with four yellow cross- 

 bands; wings with yellowish base and fore border.
