23.4 Baker: Malayan Jassoidea 397 



ing caudad to the transverse furrow of scutellum. Tegmina 

 translucent, subcostal area hyaline and apically with two widely 

 separated pale fuscous oblique stripes, the second near to apex. 

 Length, female, 6.5 millimeters ; male, 5.25. 



Front strongly flattened to extreme base and nearly to lateral 

 margins, the narrow sides convexly rounded; the delicate me- 

 dian carina is stronger and considerably raised at base. Basal 

 lateral areas of face somewhat as in Pseudonirvana longitudi- 

 nalis, but the supra-antennal area broader; the minute ocellus 

 is situated beneath the bordering carina and about four times its 

 diameter from eye; the bordering carina is weak just before 

 ocellus and becomes obsolete behind it where it is lost in the 

 minute wrinkles on lateral fold 'of vertex. Length of vertex 

 (Plate 5, fig. 43, a) two and a half times interocular width; 

 surface evenly gently concave, smooth except for scattering 

 punctures, and usually white waxy pulverulent. Length of pro- 

 notum equaling interocular width, anterolateral margins far 

 longer than posterolateral, and into width little more than 

 two and a half times ; anterior margin unusually broadly rounded. 

 Scutellum very large, longer than pronotum, the median basal 

 area smooth. Venation (Plate 5, fig. 43, d) peculiar because of 

 the very large and long second apical cell, which is narrowed 

 apically, and the small, short third apical, which is strongly 

 broadened apically; in the male (Plate 5, fig. 43, c) one cross 

 vein in subcostal area may be quite distinct, while in the female 

 both cross veins may be indistinguishable. Subgenital plate of 

 female with hind margin truncate as in most species of this 

 family. 



Amboina (Muir). During his Moluccan travels, Mr. Muir 

 found this species only on Amboina. 



Genus PYTHONIKVANA novum 



Type, Pythonirvana muiri sp. no v. 



Characters as given in the generic synopsis, combining some 

 of the characters of Pythamus and Nirvana and yet widely dis- 

 tinct from both. It is in many respects a connecting link 

 between them. 



Pythonirvana muiri sp. nov. Plate 5, fig. 44. 



Shining black; venter with lateral abdominal margins (except 

 subgenital plate and genitalia), legs, and antennas pale ochra- 

 ceous ; a small oval yellow spot next to margin on either side of 

 vertex halfway between ocellus and apex; a large triangular 

 lemon yellow spot at middle of clavus, its long side on the
