toward apex of tegmina the black becomes deep 

 fuscous. Length, female, 5.5 millimeters; male, 5. 



Head from above with the appearance somewhat of Nirvana, 

 but viewed from side deep throughout, the lower frontal line 

 concave. Length of face (Plate 5, fig. 44, c) one and two- 

 thirds times the width, the front more than two times longer 

 than wide; clypeus strongly narrowed to apex; lorae minute. 

 Front rugose-punctate on the concave apical half and coarsely 

 obliquely wrinkled on the strongly protuberant basal half. Su- 

 pra-antennal carina strong, oblique, and some distance above in- 

 sertion of antennae, the supra-antennal area smooth ; basal lateral 

 areas of face with the lateral oblique folds strongly carinate, one 

 of these carinae extending toward upper margin of eye, closely 

 subtending the ocellus, and joining bordering carina near eye, 

 leaving between it and the bordering carina a deep narrow 

 lateral sulcus in which the ocellus is located, the latter some 

 five or six times its diameter from eye. Length of vertex 

 (Plate 5, fig. 44, a) a little less than twice interocular width, 

 surface deeply concave, a little raised toward median line where 

 there is a strong uniform median carina reaching to near apex; 

 the bordering carina is sharp, strongly raised, incurved above 

 ocellus, and continuous with lateral carina to base of eyes, the 

 obtuse lateral folds of Nirvana being here high and sharp ; inte- 

 rior surface smooth, except for scattered punctures, and irreg- 

 ular wrinkles on lateral slopes; basal margin of vertex not 

 carinately raised ; lateral margins parallel. Length of pronotum 

 into vertex one and a half times, the anterolateral margins 

 distinctly longer than posterolateral, into width three and a half 

 times; hind margin broadly subangularly emarginate; larger 

 part of surface very coarsely transversely rugose-punctate, 

 coarsely punctate apically and with two small smooth areas 

 behind eyes. Median basal area of scutellum coarsely rugose- 

 punctate, apical area minutely rugose. Basal portion of clavus 

 and base of subcostal area closely coarsely punctate ; veins bor- 

 dering radial and medial areas distinct except* at base; first, 

 second, and third cells regularly gradated in length, the third 

 shortest ; one oblique cross vein in subcostal area. Head much 

 narrower than pronotum. 



Borneo, Sandakan {Baker). Amboina (Muir). The single 

 specimen taken by Mr. Muir in Amboina is identical with the 

 Sandakan specimens. With the narrow head and the coarse 

 sculpture, this has a remarkable resemblance to Pijthamus, and 

 yet it is properly one of the Nirvaniidse.
