AHCROLEPIDOPTERA OF PHILIPPINE ISLANDS 73 



with four grey marks, alternating with minute strigulae, exterior 

 two marks small, interior larger, triangular; space beyond upper half 

 of transverse fascia as far as third costal mark filled with dark slate 

 grey, forming a triangular patch; this patch and lower part of trans- 

 verse fascia bordered posteriorly by a conspicuous inwards-oblique 

 fascia of whitish ground color from costa before apex to 3/4 of dorsum, 

 parted above by an olive fasciate mark, below by a grey line; terminal 

 area beyond this pale fascia separated in two parts by a triangular 

 blackish spot just above middle of wing, with erected angles, posterior 

 angle restmg on middle of termen, continued downward as a short 

 marginal streak, base of triangle horizontal; apex above triangle 

 dark grey; tomal area below triangle pale grey posteriorly, pale olive 

 anteriorly; a small dark transverse strigula in apex, continued down- 

 ward so as to form a suffused terminal fascia to tornus. Cilia dark 

 grey with a whitish basal line and a black subbasal band. 



Hind^nng dark fuscous, darker toward margin, paler toward 

 base and dorsum. Cilia whitish grey, with an ochreous-whitish basal 

 line and a darker grey subbasal band, cUia opposite apex suffused 

 with dark grey. 



Male genitalia: Very similar to those of G. lecithocera Meyrick, but 

 with left valva only slightly asymmetrical, both sacculus and cucullus 

 being a trifle broader left than right; the knob with black spines at 

 the bottom of the primary incision is larger than in lecithocera; Spci 

 right is rather short and small, left it is double : a pencil of long hair- 

 like bristles, and above it a large patch of shorter ones. Uncus, 

 gnathos, aedeagus and anellus are very much the same, and striking, 

 as in that species.

Type species: Peridaedala hierograpta Meyrick, 1925 (New Guinea). 



The genus represents a natural group; the species can easily be 

 recognized. Until recently, it was knoA\Ti only from New Guinea 

 where five species occur. Now there is also a species from Assam 

 and another from Java which have been attributed to Peridaedala. 



It is of considerable interest that a series of six closely allied species 

 appear to inhabit the Philippine Islands. I regard these species as
