Pygofer asymmetrical; right side produced into a large pro- 

 cess rounded at apex, left side with a small projection near 

 anal angle; medioventral process subconical in outline. Anal 

 segment asymmetrical, the left margin being much lower than 

 the right. Genital styles small, flat laterally, bent in middle to 

 nearly a right angle, apex bluntly pointed. Periandrium with 

 apical two-thirds membranous, basal third chitinous, a large 

 process on ventral aspect bifurcate at apex, one very small and 

 the other larger and curved, two small spines on the right side ; 

 sedeagus membranous. 



Stramineous ; darker over abdomen. Tegmina hyaline, apices 

 of apical veins fuscous extending a little way down, apical 

 crossveins fuscous, a few small spots at crossveins, one at apex 

 of costa, one at fork of Sc and R, one at fork of Cu, one at 

 apex of clavus, one at fork of clavus ; veins stramineous except 

 at spots, tubercles minute, same color as veins. Wings hyaline, 

 veins slightly stramineous. 



Female.— Length, 2.2 millimeters; tegmen, 3. In color a 

 little darker than male, especially over the abdomen. 



Luzon, Laguna Province, Los Banos (Muir) , September, 1915, 

 2 males and 8 females; (Baker 1304), 1 female: Tayabas Prov- 

 ince, Malinao (Baker), 1 female. Type No. 1069. 

 Myndus mindanaoensis sp. nov. Plate 1, fig. 2. 



Male.— Length, 2 millimeters; tegmen, 2.8. In build and 

 coloration this species is very similar to M. maculosus, but the 

 genitalia differ as follows: 



Right lateral margin of anal segment produced into two pointed 

 processes; the production on right margin of pygofer longer 

 and narrower at base, the angular projection on left side larger ; 

 genital styles larger with three small lobes at apex; the basal 

 portion of periandrium having one bilobed process with lobes 

 short, pointed, curved, and of equal length. 



Female.— Length, 2.7 millimeters; tegmen, 3. Similar to M. 

 maculosus, but slightly darker and the spots on tegmina darker. 



Mindanao, Kolambugan (Baker), 1 male: Dapitan (Baker), 

 2 females. Type No. 1070. 



Myndus palawanensis sp. nov. Plate 1, fig. 3. 



Male.— Length, 2.3 millimeters; tegmen, 2.7. Vertex slightly 

 longer than width at base, base considerably wider than apex ; 

 frons slightly longer than wide, narrowest at base. Sc -f R 

 forking about middle of costa, Cu forking slightly more distad.
