c 1 . Scutellar spine but slightly longer than scutellum; height of head 
above eye equal to depth of eye G. turbinata Schmidt. 
c\ Scutellar spine a half or nearly a half longer than scutellum; height 
of head above eye greater than depth of eye (Plate II, fig. 14; 
Plate III, figs. 2 and 6) G. tricolor sp. nov. 
b 1 . Scutellar spine strongly decurved, its apex near apex of tegmina; 
height of head above eye much less than depth of eye (Plate II, 
figs. 12 and 15; Plate III, figs. 3, 7, 9) G. breviceps sp. nov. 
Grypomachserota borneensis sp. nov. 
Female . — Length to end of abdomen, 5 millimeters; to ends 
of tegmina, 6.5; to end of spine, 7. 
Stramineous ; lower part of face, sternum, and venter piceous, 
the latter sometimes paler; frons piceous basally and apically, 
the middle two-fourths stramineous, and each side with eight 
narrow oblique piceous stripes; vertex dark brown except the 
stramineous superior cheek arete, an area connecting ocelli, and 
the postocular areas. Punctures of pronotum brown, this ren- 
dering conspicuous the stramineous reticula, median carina, 
and posterolateral borders. Scutellum and base and lower bor- 
der of spine pale brown; lateral pale stripes on body of scu- 
tellum straight, oblique, passing backward and upward to beyond 
middle ; median dorsal line on body of scutellum and entire upper 
portion of spine except at base (where it is piceous), strami- 
neous ; posterior margin of body of scutellum shortly and broadly 
yellowish and immediately above this piceous; the inferolateral 
border also narrowly yellowish. Tegmina slightly suffused with 
stramineous apically, the veins brown to piceous. Legs brown 
to piceous, apices of femora and nearly all of tibiae stramineous. 
Frons finely, transversely, rugosely wrinkled and shining, more 
coarsely sculptured below and on clypeus; frons evenly convex 
on lower half, but with a strong median carina on upper half, 
this reaching the upper angle of appendage, where the lateral 
margins are also sharply carinate. Vertex horizontally rugose, 
with a median carina which apically becomes sharply raised and 
double; lateral arese of frontal portion of vertex concave. Pro- 
notum coarsely reticulate-punctate except near anterior border, 
the reticula not sharp; four small, depressed, oblique, finely 
sculptured areae near fore margin as in Machzerota. Scutellum 
sculptured like pronotum, the furrow cross wrinkled and with 
the upper carina of spine scarcely entering it; spine at base 
with lateral disks sharply longitudinally depressed, its point 1.5 
millimeters above apex of tegmina. 
This is a common species at Sandakan, British North Borneo.
