more than three times, the hind margin shallowly subangularly 

 emarginate; with a distinct median carina on anterior two- 

 thirds ; median area and basal lateral margins of scutellum very 

 coarsely but shallowly thimble pitted ; the yellow apical area of 

 scutellum and two lateral dots before it callose and smooth. 

 Tegmina with clavus grossly thimble pitted basally, apically 

 the pits become subobsolete, and largely wanting in the albescent 

 subcostal spots; without supernumerary cross veins. 

 Borneo, Sandakan (Baker). 



Pythamus melichari Baker var. singaporensis var. nov. Plate 2, 

 fig. 14. 

 Differs from var. bilobatus as follows: Mesopleura with only . 

 a small blackish mark anteriorly. Ovipositor dark only at apex. 

 Lateral yellow spots on vertex large and reaching basal carina; 

 transverse band before apex of different shape (Plate 2, fig. 14, 

 a). Pale area of tegminal subcostal area expanded into medial 

 area and proximad of medial area. Length of female, 6.5 milli- 

 meters. 



Length of vertex a fourth greater than width between eyes. 

 Pronotum (Plate 2, fig. 14, a) as long as vertex, the anterolateral 

 margin into width three and a half times. Apical area of scu- 

 tellum basally sparsely strongly punctate.

 Pythamiis melichari Baker var. borneensis var. nov. Plate 2, fig. 15, 

 Differs from var. bilobatus as follows: Black of dorsum with 

 strong bluish reflection. Transverse band before apex of vertex 

 of different shape (Plate 2, fig. 15, a). Pale area near outer 

 margin of tegmina small and narrow and confined to subcostal 

 area. Tegmina equally dark to the albescent apical border. The 

 usual ocellar black spot invades a large part of ocellar area ; the 

 usual antennal spot occupies entire scrobe and invades lateral 

 margin of front; upper outer angle of gense black. Length of 

 female, 7 millimeters. 



Length of vertex a fourth greater than width between eyes. 

 Pronotum (Plate 2, fig. 15, a) as long as vertex, the anterolateral 

 margin into width three times. Apical area of scutellum en- 

 tirely rugose-punctate. 



Borneo, Sandakan (Baker). This brilliant form, so distinct 

 in appearance, is yet very close to melichari in all essential struc- 

 tural characters. The figure of the tegmen (Plate 2, fig. 15, d) 

 shows the simple type of venation common to melichari and its
