Female. — Abdomen yellowish, tergites darker, sternites brown- 

 ish along anterior margin. 



Length, 3.5 millimeters ; tegmen, 3.2. 



Luzon, Mount Maquiling (Baker, Muir). Mindanao, Davao

Tropidocephala baguioensis sp. nov. 



Apex of face ovate, not truncate, the lateral carinas continuing 

 and meeting, together dividing frons from clypeus ; face straight 

 in profile, clypeus forming a wide angle with face (about 130°), 

 median carina on clypeus large. Vertex nearly one and a half 

 times the length of pronotum (1 to 1.4). 



Light brown; carinse of vertex and pro- and mesonotum bor- 

 dered with a fine black hair streak, most distinct along median 

 carinse; a fine black ring round apex of first antennal joint and 

 round middle and apex of second; abdomen darker brown; teg- 

 mina brown, darkest over basal area between clavus and costa, a 

 hyaline mark in clavus along suture, another from end of cla- 

 vus to costa, broadest on claval margin, a hyaline spot in sub- 

 costal, radial, and first and second median apical cells; veins 

 dark, studded with small white granules, a dark spot on media 

 and another on clavus just in front of cross veins ; wings slightly 

 fuscous, veins brown. 



Pygophor oval, a small knobbed spine on medioventral margin, 

 no spines on lateral margins; genital styles narrow, the inner 

 apical corner produced into a flattened, narrow, curved process 

 with a rounded apex; the outer apical corner produced into 

 a small, blunt spine, from the base arises a large, slightly crooked 

 spine. 



Length, 2.7 miUimeters; tegmen, 3.3. 



Female. — Unknov^Ti. 



Luzon, Baguio (Baker) . 



The markings on the tegmina and the shape of the genitalia 

 of this species are very similar to those of T. amboinensis Muir. 



Tropidocephala pseudobaguioensis sp. nov. 



In coloration and shape and proportional size of head this 

 species is similar to T. baguioensis; the antennae have only one 

 fine black ring which is on the second joint. 



Pygophor with a knobbed spine on medioventral edge, no spines 

 on lateral edges, styles flattened, from inner basal edge there 

 arises a long, curved, flattened spine, with granulated surface, 

 on outer edge near base there arises a short, broad, flattened 

 spine, both these basal spines stand at right angle to the surface
