MACRONEMATIN^^ 



Key to the genera, 

 a^. Palpi lacking. 



6\ No median cell; discoidal cell very broad; venation peculiar. 



(Estropsyche. 

 b'. Median cell present. 



c^. Discal all present, normal Polymorphanisus. 



c^. Discal all absent or abnormal (Ethaloptera. 



a'. Palpi present. 



d'. Discal cell of fore wings closed Macronema. 



d^ Discal cell of fore wings open or lacking; some costal cross veins. 



Amphipsyche. 

 (Estropsyche vitrina Br. 



Recorded from the Philippines; I have not received it. 



Polymorphanisus semperi Br. 



Described from the Philippine Islands; I have three from 

 Mount Maquiling. A large, green caddice fly, the male with 

 hyaline streaks in apex of wing. 



Macronema bella sp. nov. Plate II, fig. 19. 



Head, prothorax, two basal joints of the antennae, all coxae 

 and femora, and the hind tibia nearly golden yellow; rest of 

 the antennse, front legs, and thorax black; rest of body and 

 middle and hind tibia brown. Fore wings rich dark brown, 

 with several clear, silvery white marks as in the figure; a sub- 

 apical streak, two costal spots, tending to form a V, one behind, 

 with a basal extension, a small costal mark toward base, another 

 small median spot nearer base, and a double, oblique mark 

 behind; the latter may be broken into two spots. Hind wings 

 not quite as dark as the fore wings, with two white costal spots 

 toward tip. Fore wings not very acute at tip and rather 

 narrow; fork 1 with pedicel one half as long as discal cell, the 

 latter twice as long as broad, and rather broader than the median, 

 but latter one third longer. Venation black, except on the 

 white spaces. Vertex with large, nearly circular anterior warts, 

 not their diameter apart, posterior warts not one fourth as large, 

 subtriangular ; mesonotum polished. Male inferior appendages 

 slender, apical part about as long as basal ; barely clavate. 



Expanse, 36 millimeters. 



Luzon, Tayabas, Malinao (Baker). 



HYDROPSYCHIN^ 

 Key to the genera, 



a^. Fork 4 of fore wings as long as fork 5, or fork 5 absent. 



fe\ Fork 5 absent; spurs 3, 4, 4 Pseudoneureclipsis.
