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 alw r ays 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. 0

Straits Settlements. 
Macharota philippinensis sp. nov. 
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 areas, 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 areae, which do not reach anterior 
margin, and are thickly, minutely punctate or shagreened within. 
Body of scutellum coarsely reticulate-punctate ; scutellar furrow
