dark-colored forms come from Palawan. The palest forms in 

 my collection were taken in Imugan, Nueva Vizcaya Province, 

 Luzon. The very broad, shining, black, median portion of face, 

 broader above, is also characteristic in all color phases; in the 

 Luzon forms this dark color is lacking on the lower frons and 

 on clypeus, whereas in the dark Palawan forms it is broad 

 throughout ; only rudiments of horizontal, lateral, frontal stripes 

 are present in any of the color phases. The four slightly de- 

 pressed and finely sculptured oblique areae near anterior border 

 of pronotum are concolorous. The spine is scarcely curved 

 where *it joins body of scutellum, and its point is about 1.5 

 millimeters above apex of tegmina. 



Abundant throughout the Philippine Islands. 



Machaerota fusca sp. nov. 



Female. — Length to end of abdomen, 5 millimeters; to ends 

 of tegmina, 7.25; to end of spine, 8.5. 



Color stramineous to chocolate, to piceous, and strongly con- 

 trasted. Entire face black; vertex, pronotum, and scutellum 

 chocolate; posterolateral arese of pronotal disk stramineous; 

 lateral angles of pronotum shining piceous; lateral areae of 

 vertex and short longitudinal stripes inclosing the ocelli pos- 

 teriorly, stramineous ; lateral yellow stripes on body of scutellum 

 long, straight, more than two-thirds length of scutellar body 

 and somewhat broader caudad; posterior border of scutellar 

 body very narrowly and shortly yellowed; scutellar spine piceous. 

 Pleurae stramineous; venter piceous to brown; legs brown, 

 femora stramineous at apex, fore and middle tibia? stramineous 

 at base, hind tibiae stramineous on basal three-fourths. Ab- 

 domen stramineous above, with broad longitudinal lateral areae 

 brownish, the narrow venter brownish. Tegmina suffused with 

 stramineous in the region of apical cells, where the veins are 

 pale brown; the remainder of corium subhyaline with piceous 

 veins. 



Frons shining and nearly smooth except apically, laterally 

 with subobsolete indications of a few horizontal lateral grooves ; 

 clypeus subrugose. Supra-antennal areae of vertex foveate; 

 frontal area of vertex depressed and with a delicate median 

 carina, the true vertex rugose between the ocelli. Pronotum 

 very coarsely reticulate-punctate except near fore margin, the 

 reticula not sharp ; the four finely sculptured depressed areae near 

 anterior margin very small; median ridge of pronotum weak, 

 becoming obsolete posteriorly. Body of scutellum as coarsely 

 sculptured as pronotum but more irregularly; scutellar furrow
