438 Prof. J. Wood-Mason on a new 



though rather sparsely granulated on the disk, not very 

 coarsely denticulated on the sides, the denticles increasing in 

 size and becoming truncated towards the constriction, where 

 they cease ; Indian-yellow, with the hinder border and a fine 

 line therefrom forwards to a semicircular blotch in the middle 

 of the hinder lobe, the bottom of the supra-coxal groove in 

 the middle, and a V-shaped mark on the anterior lobe con- 

 nected therewith, all dark brown ; presternum paler, with a 

 regular crescent-shaped black-brown mark, the concavity of 

 which is directed forwards, situated about midway between 

 the insertion of the fore legs and the hinder margin, and 

 extending right across the part so as to embrace the lower 

 edges of the pronotum. 



Abdomen pale testaceous, concolorous with the ventral 

 surface of the thorax and the leg-bases, with a pair of fuscous 

 spots near the posterior angles of terga 2-6 inclusive, and on 

 sternum 7. 



The organs of flight when closed extend by about one sixth 

 of their length beyond the extremity of the abdomen. 



Tegmina three times as long as broad, rather acutely 

 pointed, oval ; the marginal field coriaceous, opaque, cinnabar- 

 red, the rest (except the membranous anal gusset, which is 

 yellowish milky) semiopaque, yellow, with three opaque 

 green radial spots, one small and roundish midway between 

 the base and the stigma, and two about thrice as large and 

 transversely elongated situated one at each end of the stigma; 

 the stigma long, linear, concolorous with the wing-membrane, 

 and placed upon the posterior radial vein at a distance from 

 the base equal to twice its own length, apparently diffused 

 over the veinlets of the cell immediately behind it; both v. 

 dividens and 4-branched v. plicata anastomosed with the 

 posterior ulnar vein, as in Hymenopus bicornis. 



Wings somewhat more pointed even than the tegmina, 

 semiopaque, greenish cream-coloured, with the outer half of 

 the anterior margin and the apex semiopaque, reddish yellow, 

 and with the outer margin of the anal area narrowly and 

 decreasingly to the anal angle subhyaline, faintly tinged with 

 fuscous of a vinous tint ; the anterior ulnar vein emits only 

 two branches, and its extremity is in correspondence with the 

 extremities of the veins in front of it and with the anterior 

 margin, distinctly arched. 



Legs Indian-yellow, more or less flushed with red, but not 

 barred. Fore tibias armed on the outside with 23 and on the 

 inside with 17 teeth. Foliaceous lobes of the four posterior 

 femora moderate, not more than 1'5 millim. wide in their 

 widest part.
