23.4 Baker: Malayan Jassoidea 3^5 



Length of face (Plate 2, fig. 11, c) a little more than one and 

 a half times the width across eyes. Lorae smooth; gena? 

 obscurely and transversely rugose near lateral margins; front 

 shagreened; lateral surfaces of raised basal portion of frontal 

 ridge rugose. Supraocular carina sharply bordering anterior 

 margin of vertex, subocellar carina weak and irregular but dis- 

 tinct from near ocellus to apex of front; area between these 

 carinse and to the supra-antennal carina irregularly transversely 

 wrinkled. The ocellus lies below and touches the superior 

 carina and is distant from eye about three times its diameter. 

 While the outlines of front are distinct in facial view, the 

 lateral suture actually becomes obsolete just above the supra- 

 antennal carina. Laminate carina of vertex highest on anterior 

 half, the lateral concavities in deeper anterior portion sub- 

 obsoletely concentrically wrinkled at sides, smooth in shallow 

 posterior portion. Length of vertex nearly a third greater than 

 width between eyes. Pronotum (Plate 2, fig. 11, a) slightly 

 shorter than vertex, the anterolateral margin into width three 

 and a half times, the hind margin subtruncate ; a broad median 

 basal area reaching forward to three-fourths of length, minutely 

 thickly transversely aciculate ; remainder of surface on posterior 

 half with sparse subobsolete punctures, on anterior half smooth, 

 without trace of median carina. Scutellum wider than long and 

 about three-fourths length of pronotum, otherwise as in P. meli- 

 chari. Veins in tegmina weakly and subobsoletely pit margined, 

 the surface of clavus smooth. Several supernumerary cross 

 veins occur in both clavus and corium, one of these forming an 

 inner subapical cell. The subgenital plate of female is deeply 

 broadly emarginate, beyond apex of emargination and at sides 

 strongly callosely swollen. 



Straits Settlements, Penang Island (Baker). The largest 

 and most conspicuous species of the genus. 

 Pythamus decoratus sp. nov. Plate 2, fig. 12. 



Face, sternites, most of vertex, anterior margin and a con- 

 nected median stripe on pronotum, basal angles of scutellum, 

 and an irregular median stripe extending from base to transverse 

 furrow black. Anterolateral borders of head, eight small spots 

 arranged around margin of vertex, and submedian and apical 

 areas of scutellum yellowish. Pronotum in large part and veins 

 of tegmina testaceous. Legs pale ochraceous; abdomen with 

 pale brown segmental margins. Tegmina very dark smoky, two 

 adjoining subcostal spots albescent, the proximal smaller; ex-
