alone ; it is more than likely that important differences are presented hy 

 the secondary sexual characters, such as gland-openings, occurring on the 

 dorsal surface, and by the form oi: the supra-anal lamina ; but since these are 

 not visible in the specimens before me I have relied on the slight differences 

 in the form of the sub-genital laminse and styles and in the size.

? ? . Nos. 5504, 5555, 6724, 6732, 6704, larvse Nos. 5486, 6711. 

 (J . Dark castaneous. Yertex of head not covered by pronotum. Eyes 

 wide apart. Antennas not exceeding the apex of tegmina. Pronotum 

 trapezoidal, posteriorly truncate, exposing the scutellum, lateral margins 

 hyaline, but the hyaline not extending to postero-lateral angles which are con- 

 colorous with disc. Tegmina exceeding the apex of the abdomen, lateral 

 margins narrowly hyaline ; mediastinal and radial veins simple, 10-12 costals, 

 discoidal field strongly reticulated, anal vein well-marked. Sub-genital 

 lamina sub-trapezoidal, symmetrical, posterior margin slightly notched in the 

 middle, styles minute, situated in small notches. Gerci pointed, 13-joiuted, 

 not exceeding apex of tegmina. Titillator strongly hooked, apex rounded. 

 Front femora on anterior margin beneath with 4 spines, succeeded distally 

 by piliform spines, 3-4 spines on posterior margin ; remaining femora with 

 4-5 spines on anterior margin beneath, 3-4 spines on ])osterior margin. 

 Metatarsus much longer than remaining joints. 



$ . Shorter and broader, tegmina barely exceeding apex of abdomen ; 

 hyaline margins of pronotum broader ; sub-genital lamina ample, produced, 

 apex notched. Gerci stouter. 



Length (c^^) 10-5-14-5 mm. ; (?) 12 mm. 



None of the specimens are in a very good state of preservation and it is 

 not easy to make out the details of structure in them, the difficulty being 

 increased by the dark' colour of the species. The incomplete hyaline lateral 

 margins of the pronotum afford the most obvious character whereby to 

 recognize the species. There is considerable variation in size, and it is a 

 little difficult at first to believe that the smallest example is specifically 

 identical with the largest; but even after the most careful examination I am 

 unable to find any character on which to separate the smill specimens from 

 the large. It is possible that the wing-venation or the structure of the supra- 

 ;inal himina might present discriminating characters, but as they are not 

 visible in any of the specimens before me I have no option but to regard the
