xv, i Baker: The Malayan Mackserotmse 77 
proportions of scutellum or of pronotal laminae. The structure 
at the base of the scutellar spine as shown for the Sumatran 
species described by Schmidt, 8 Maxudea crassiventris, is so en- 
tirely different from that of a species obtained from Penang, 
that it is necessary to maintain the latter as distinct, at least 
until better structural data as to M. crassiventris can be secured. 
Key to the species. 
a 1 . Lower margin of scutellar spine, above posteroinferior angle, strongly 
concave .M. crassiventris Schmidt. 
a 2 . Lower margin of scutellar spine, above posteroinferior angle, straight. 
M. schmidtii sp. nov. 
Maxudea schmidtii sp. nov. 
Female. — Length to end of abdomen, 6.5 millimeters ; to ends 
of tegmina, 7.5; to end of spine, 8; breadth from tip to tip of 
pronotal laminag, 5. 
Color largely piceous, the pronotal laminee shining. Face 
stramineous, a broad median stripe and lower third of frons 
and clypeus black; lateral portions of frons with about eight 
dark horizontal lines; vertex stramineous with dark sutures; 
the frontal horizontal lines continued to ocellar (true frontal) 
transverse suture. Anterior portion of pronotum stramineous, 
with four dark spots; disk of pronotum piceous, laminae black. 
Scutellar body stramineous with dark punctures, without yellow 
lateral marks or yellow posterior margin, the spine and infe- 
rolateral margins of scutellar body chocolate. Abdomen pic- 
eous, the segments with paler margins. Legs reddish brown, 
basal two-thirds of femora black. Tegmina suffused with stra- 
mineous, veins brownish, darker basally. 
Frons shining, irregularly shallowly roughened, the horizontal 
lines being distinct shallow furrows; clypeus coarsely trans- 
versely wrinkled. Frontal portion of vertex with an acutely 
triangular median depression just in front of ocellar suture. 
Pronotum thickly, coarsely reticulated punctate except near an- 
terior margin, the reticulse and median carina sharp (stronger 
anteriorly) ; the four small depressed arees near fore margin are 
irregularly subcircular; anteriorly and posteriorly the flattened 
laminse are sharp margined; subparallel with anterior margin 
of lamina, and near to this margin, a sharp carina passes from 
disk of pronotum to tip of lamina, forming a sulcus between
