treme apical margin albescent, a concentric subapical stripe 

 subhyaline. Length of female, 6.25 millimeters. 



Length of face (Plate 2, fig. 12, c) a little less than one and 

 a half times width across eyes. Face including lorae, apical area 

 of genae, and most of clypeus thickly rugose ; clypeus shagreened 

 on median basal area; genae beneath eyes subobsoletely sparsely 

 transversely wrinkled. Subocellar carina curving downward 

 toward supra-antennal carina, three strong transverse carinas 

 between this and ocellus, the upper one subtending the ocellus; 

 area between ocellus and supra-antennal carina also with nu- 

 merous fine transverse wrinkles. Ocellus touching the normal 

 supraocular carina and distant from eye more than three times 

 its diameter. Laminate carina of vertex highest at middle, 

 tapering equally either way. Lateral concavities of vertex 

 deepest at middle, sloping rapidly upward to carinae in all direc- 

 tions and concentrically wrinkled .throughout. Length of ver- 

 tex a fourth greater than width between eyes. Frontal profile 

 (Plate 2, fig. 12, b) abruptly prominent above the clypeus. 



Pronotum (Plate 2, fig. 12, a) nearly as long as vertex, the 

 anterolateral margin into width four and a half times, the hind 

 margin very slightly incurved, the surface to near foremargin 

 sparsely shallowly punctured and transversely wrinkled, and 

 without trace of median carina. Scutellum much wider than 

 long, basal angles shagreened, median basal area rugose, apical 

 area very minutely longitudinally wrinkled. Entire clavus and 

 the basal two-thirds of corium punctate. With several super- 

 numerary cross veins, one forming a median subapical cell, two 

 other strong cross veins occurring in the medial area as in 

 Deltocephalus. The subgenital plate of female is shallowly 

 broadly angularly emarginate, a blackish spot occurring beyond 

 the apex. 



Borneo, West Borneo, Mowong (Muir). A small species, 

 but one of the most highly ornamented in the genus. The lower 

 part of the front in this species and in P. productus (in lateral 

 view) is more prominent than in other species of the genus. 

 Pythamus melichari Baker. 



In each Malayan region in which collecting has been done, 

 we have encountered forms very closely related to P. melichari 

 described from Palawan. These are all very close to melichari 

 in structure, differing only in size, in minor details of markings, 

 and in minor structural characters. In the various regions the 

 varieties or subspecies, as we may choose to call them, present
