plate incomplete, an acus present; Ih with 
2- 4 branches, very small and obscure; isc with 
13-17 branches, about equal to anal plate in 
length; ventral brush of 12 tufts, all but basal 
3- 4 arising from a connected barred area, each 
tuft with 11-15 branches. Anal gills long, 
lanceolate, dorsal pair slightly longer than 
ventral pair and about twice as long as anal 
plate. 
BIONOMICS: The adult was not encountered 
in nature. The larvae were collected from 
scattered rain pools in a grassy area, from a 
stream margin containing algae and other veg- 
etation, and from a grassy pool in the bed of 
a temporary stream.

larval skin, 1 larva, Dau, Pampanga Prov. 
(Cowell, Ingal). One male, 6 females, 4 sets 
assoc, skins, Quezon City, Manila Prov. (de 
Guia, Bruce, Baisas). Six males, 26 females. 
Camp Nichols, Rizal Prov. (Carraway, Callon, 
Sinclair). Five females, Camp Stotsenberg, 
Pampanga Prov. Mindanao: 1 larva, San Ra-

sinan. Pettit Barracks, Zamboanga, City of 
Zamboanga Prov. (Visaya.) C.A.S. Mindoro:

Unknown outside the Philippines. 
DISCUSSION: As pointed out by Bohart 
(1945: 63) this species has been confused by 
various authors with niveoscutellum (Theobald) 
and alhoscutellatus (Theobald). However, it is 
separable from the first on details of male 
terminalia and from the second on the char- 
acters given in the key.

Adult described by Barraud (1934: 250) 
and the larva by Penn (1949: 1). 
ADULT: Male. Similar to pampangensis but 
differs as follows. Head: Proboscis all dark, 
or with a paler band-like area just beyond the 
middle, this may be obsolete (except ventral- 
ly). Palpi longer than proboscis by slightly 
more than length of apical segment. Thorax: 
Scutum marked on either side with two small 
clusters of yellow scales, one on anterior mar- 
gin and the other on a line with the first and 
on a level with the scutal angle, a variable 
amount of yellowish scales may be scattered 
over the scutum. Scutellum with areas be- 
tween the lobes free of scales. Apn with a few 
broad silvery scales; ppn bare. Propleuron, 
upper sternopleuron, lower posterior sterno- 
pleuron, and upper mesepimeron each with 
small patch of broad silvery-white scales; a 
few narrow yellowish scales on the subspira-
