below there is a smooth piece with bilobed tip ; the lateral 
appendages are rather broad on basal part, smooth, and with 
a few long bristles toward tip and below, the apical part 
more slender and hairy, beneath it projects the hooked tip 
of a spur from the inner basal part. 
Fore wing 13 mm. long. 
From Wainganitu, Fiji Islands (W. M. Mann). Type 
M.C.Z. No. 22042. 
Trisenodes dubia Mosely 
A rubbed female, 7 mm. long fore wing, agrees very well 
with the figure of venation; a short fork one, long discal 
cell, irregular elongate hyaline white mark over much of the 
anastomosis. From Wainganitu, Fiji. 
Triaenodes manni sp. nov. 
Yellowish, abdomen slightly brownish, antennae with nar- 
row ring of brown at apex of each joint. Fore wings yellow- 
ish, darker over stigmal region and back broadly over anas- 
tomosis, the anastomosis itself being mostly white, some 
dark along veins toward base of wing, a dark spot at base 
of fork one and on other veins behind this, and beyond a 
more or less definite dark band across wing, a larger spot 
near end of cubitus; in female much of the apical area is 
brownish, and also most of the basal half of wing, the anas- 
tomosis, however, remains white. 
In fore wing fork one is much longer than the pedicel, 
the discoidal cell longer than its pedicel, third apical vein 
ends a little before tip of wing, no trace of stub to fifth 
apical vein, but in the field behind the discoidal cell there is 
a short longitudinal faint line or vein, possibly a remnant of 
the medius. The genitalia are much on the plan of T. 
bcettcheri Ulmer from the Philippines ; the slender superior 
median piece with the longer slender lateral pieces (both 
more elongate than in T. bcettcheri ) , the long slender spine- 
like processes reaching beyond the lower appendages, and 
with a slightly out-curved tip; the long median piece is 
curved down over the end of the lower appendages, and from 
side as well as above the tip is broad and rounded (pointed
