CHARLES P. ALEXANDER 15 



Male. — Length, 12.5 mm.; wing, 13.4 mm. 



Antennae very small, not greatly exceeding the head. Head sparsely 

 gray pruinose. Cell 1st M2 is sometimes closed by the presence of a medial 

 cross-vein which may be present in one wing and lacking in the other of the 

 same individual; when present it lies transversely across the wing, connecting 

 Mi-jf-2 with AI3. 



Male hypopygium with the pleurites stout; pleural appendages two in 

 number, the outer appendage short and rounded, the surface covered with 

 numerous stout bristles and with three long setae; inner pleural appendage 

 with the inner face produced into a long, slender arm, the apex of which 

 bears a few long setae, the caudal face set with about a dozen powerful black 

 spines. Gonapophyses flattened, narrowed to the beak-like apex. 



Tricyphona trispinosa new species 



Similar to T. kuivdnai; size smaller, wing of the male under 11 mm.; wings 

 without a row of costal black dots; a dusky seam along the cord and another 

 extending obliquely across the wing-tip from r to the end of vein M3, m present, 

 oblique in position; inner pleural appendage of the male hypopygium with 

 but three spines. 



Male. — Length, about 9.5 mm.; wing, 10.8 mm. 



Generally similar to Tricyphona knwaitai, differing as follows: The size 

 is smaller, but the general coloration of the body and the peculiar pattern 

 of the mesonotum is almost the same in the two species. Wings with the 

 yellow subcostal band paler yellow, broader and including more of the costal 

 cell, the remainder of the costal cell unicolorous, not spotted with black 

 as in kuwanai; the brown band which begins at r and runs obliquely across 

 the wing, in the present species continues across the fork of ilf 1+2 and attains 

 the wing-margin at the end of vein Mi,- the >n cross- vein is present, very oblique 

 in position and lying far out toward the tip of the wing, occupying the path 

 of the dusky band just described; a broad duskj- seam along the cord, extend- 

 ing from r-m to the fork of Cu. Male hypopygium generally similar to 

 T. kuwanai, but the inner pleural appendage with but few (three in the type) 

 chitinized spines. 



Habitat. — Japan. Holotype, cf , without exact locality or date, 

 possibly Kioto (Akio Nohiro, collector's number 28).
