furrow. All of the species possess a small, thin, semitranslu- 

 cent, decolored spot on the upper border of the spine near its 

 base. The depth of coloring is widely variable in all of the 

 species, and the males are always smaller and darker than the 

 females. Structural characters only should be depended upon 

 for classification. What appear to be the normal color forms are 

 described in the following pages. 6

 Straits Settlements. 



Maehaerota philippinensis sp. no v. 



Female. — Length to end of abdomen, 4.5 millimeters; to ends 

 of tegmina, 6; to end of spine, 7. 



Color chocolate; frontal ridge and apex of frons piceous; 

 sides of frons with ten horizontal yellowish stripes, these with 

 numerous short, coarse, appressed white hairs ; second antennal 

 joint rufous with white distal border; sides of body of scutellum 

 with curved ivory-white arese, reaching from anterior lateral 

 angles to anterior extremity of scutellar groove; the thin mar- 

 gins of scutellar groove alternately black and yellow spotted; 

 a few minute black dots on posterior lateral walls of scutellar 

 body; posterior border of scutellar body below spine ivory- 

 white, the stramineous spine separated from brown scutellar 

 body by an irregular piceous border. Veins of tegmina stra- 

 mineous with scattering piceous dots, the tegmina suffused 

 with very pale stramineous, the costa brown near base. Abdom- 

 inal dorsum black, first tergite yellow; venter largely piceous; 

 tibiae and tarsi paler brown than femora. 



Frons very minutely punctate-rugose, near clypeus and with 

 clypeus, coarsely punctate-rugose ; median ridge broad and strong 

 on upper half of frons; vertex sculptured like the frons. Pro- 

 notum deeply, coarsely reticulate-punctate, this becoming weaker 

 near anterior border; the low weak median ridge is continuous 

 throughout; on either side anteriorly are two short, broad, 

 oblique, shallowly depressed arese, which do not reach anterior 

 margin, and are thickly, minutely punctate or shagreened within. 

 Body of scutellum coarsely reticulate-punctate ; scutellar furrow
