Female. — Length, 3 millimeters; tegmen, 3.3. Same color as 

 male. Ovipositor considerably longer than pygofer, projecting 

 well beyond apex of anal segment ; pygofer longer than wide. 



Mindanao, Butuan (Baker 10074), 2 males and 2 females: 

 Iligan (Baker 10072), 1 female. Type No. 1066. 



Myndus obscuratus sp. nov. Plate 1, fig. 5. 



Male. — Length, 3 millimeters; tegmen, 3.8. Length of vertex 

 in middle equal to width at base ; transverse carina about middle ; 

 face about as wide as long. Forking of Sc and R about middle 

 of costa, Cu forking slightly more distad. 



Pygofer asymmetrical, the right side being produced into a 

 large process, medioventral process angular. Anal segment 

 asymmetrical, in lateral view the left side of the ventral margin 

 produced into a large angular process slightly curved, the dorsal 

 margin into a large angular process, the apex pointed, the right 

 side not so produced. The genital styles curved, with a large 

 rounded process in the middle of the inner margin, apex slightly 

 rounded. Periandrium fairly large with seven or eight spines as 

 in figure. 



Stramineous; slightly darker over vertex and middle of 

 mesonotum. Tegmina hyaline, very slightly stramineous ; veins 

 stramineous, slightly fuscous on apices; tubercles numerous, 

 minute ; a faint fuscous mark at apex of clavus. Wings hyaline, 

 veins light brown. 



Female.— Length, 3.4 millimeters ; tegmen, 4. Similar to male 

 but darker over thorax and abdomen; ovipositor projecting be- 

 yond the pygofer, pygofer longer than wide. 



Luzon, Mount Banahao (type locality) and Mount Maquiling 

 (Muir), February, 1914; (Baker 2824, 2883, 10071), 5 males 

 and 3 females. Type No. 1068. 

 Myndus semialbus sp. nov. Plate 1, fig. 6. 



Male.— Length, 2 millimeters; tegmen, 2.5. Length of vertex 

 in middle very slightly less than width at base, apex slightly 

 narrower than base; transverse carina in middle, distinct. 

 Length of face equal to width, narrowest at base, widest before 

 apex, frontal ocellus distinct. Forking of Sc and R about one- 

 third from base, M leaving Sc + R near base, Cu forking 

 slightly before apex of clavus, M with five apical veins. 



Pygofer symmetrical, medioventral margin produced into a 

 process subconical in outline, lateral angles produced into a 

 rounded process which is produced into a spine on the lower 

 portion. Anal segment large, asymmetrical, the ventral margin
