132 Christmas Island. 



The basal portion of the cerium is much mottled with white. 

 The lower part of the hind margin is dotted with Avhite, and the 

 marginal portion of the tegmen is marked off on the inside in one 

 specimen by a row of hardly indicated white dots. "Wings 

 hyaline, with broad pale-brown borders. The fringes of both 

 the tegmina and wings consist of very short, straight, isolated 

 bristles, only visible under the microscope. Before the tip of the 

 tegmina is a slightly oval black spot, rather large for the size of 

 the insect. 



Two specimens, North Coast, January, 1898. 



The white markings and well-marked subapical black dots will 

 easily distinguish this interesting little species. 



^ PAUROSTAURIA, Kirby, gen. nov. 



Front quadrangular, broader than long, slightly expanded below, 

 and with a central carina. Vertex transverse, about three times 

 as broad as long, and gradually concave behind. Pronotum curved, 

 transverse, mesonotum oval, tricarinate, rather long. Tegmina 

 hyaline, very broad at the extremity, the costa slightly arched, 

 much longer than the inner margin, which is a little shorter than 

 the hind margin. Apex much rounded, and hind margin curving 

 obliquely to the hinder angle, which is obtusely rounded ; inner 

 margin convex. Costal cell with oblique transverse nervules ; 

 subcostal cell free ; basal cell oval, broader than long. Three 

 longitudinal nervures running from the basal cell, the upper one 

 forked close to its base, and the branches again forking at about 

 half their length, and ultimately throwing off long forks to the hind 

 margin. The middle nervure forks a little further from the base, 

 and once or twice more before or near the middle of its length ; 

 the lower nervure forks only once, at about half its length. An 

 obsolete nervure curves round inwards from the costa at three- 

 fourths of its length to the base of the first fork of the lower 

 branch of the middle longitudinal nervure. Before the apex of 

 the tegmen is a large black stigma, and the marginal area, which 

 is rather broad, is marked off by a row of pale nervules between 

 the nervures. The clavus throws off a vein of about half the rest 

 of its length near the base, which curves to the inner margin ; 

 between and beyond are several transverse nervules. Wings 

 hyaline, much shorter than the tegmina, the three upper 

 longitudinal nervures variously forked, and connected by two 

 oblique tratnsverse nervures. Hind tibiae bispinose. 



AXlicdxo'^Ricanoptera, Melichar ; but it does not appear to be 

 congeneric with the species of that genus before me. Inter alia, 

 the subapical spot seems to be always absent in Ricanoptera. The 

 name Paurostauria has been suggested by the paucity of cross- 

 nervures in this insect.
