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*. Lower margin of scutellar spine, above posteroinferior angle, straight. 



M. schmidtii sp. nov. 



Maxudea sclimidtii 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 laminae, 5. 



Color largely piceous, the pronotal lamina? 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, lamina? 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 reticular and median carina sharp (stronger 

 anteriorly) ; the four small depressed areae near fore margin are 

 irregularly subcircular; anteriorly and posteriorly the flattened 

 laminae 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
