This species seems, at first sight, closely allied to Ph. 

 Forstenii of De Haan ; but the very peculiar shape of the 

 wings and the dilated anal styles of the male, together with 

 the reticulated costal area of the wings of the male (not 

 noticed in this sex by De Haan, although he describes it in 

 the characters of the female of his Forstenii), the much 

 larger size of the insect, and smaller head, prove it to be a 

 distinct species. The general surface of the body is smooth, 

 opake, and black. The head as wide as the metathorax, 

 with the eyes large. The tegmiiia are minute, stipuliform, 

 with the outer angle of the apex slightly produced. The 

 wings are dark brown, with black longitudinal veins ; the 

 costal area is of the same colour, but its anterior margin 

 is luteous, and it is thickly reticulated with veins of the 

 same colour. The abdomen is long and slender, clavate 

 at its extremity ; the anal styles deflexed and incurved, 

 gradually widening to beyond the middle, and with the apex 

 obliquely truncate ; the seventh ventral is distinct ; but 

 the eighth and ninth are coalesced into a convex joint, 

 not suddenly swollen at the base. The legs are short and 

 rather thick ; the anterior femora straight at the base.

 (olim nostr.) et B.M. 



This is more robust than several of the closely allied 

 species, and is further distinguished by the shorter rounded 

 wings, unicolorous body, and very numerously dotted costal 

 area of the wings. The head is rather broad and convex. 

 Antennae about 50-jointed, moderately long and slender, 

 especially at the tips, where the joints are almost indistinct. 

 Protborax about two-thirds of the length of the mesotho- 

 rax, its anterior division convex. Mesothorax nearlv cylin- 



drical, with a fine line on each side within the lateral margin. 

 Tegmina minute, erect, stipuliform, pale luteous. Wings 

 of moderate size, broad, each covering more than half a 

 circle, pale brown, with darker longitudinal veins, the trans- 

 verse ones semitransparent ; costal area pale luteous buff, 

 with the cells (formed by the minute transverse veins) brown ; 

 median vein simple. Abdomen rather long, convex, smooth, 

 slightly constricted at the sixth segment ; the three follow- 

 ing slightly swollen; terminal one rounded at the extre- 

 mity ; anal styles minute, obtuse. Operculum compressed, 

 nearly extending to the extremity of the ninth dorsal seg- 

 ment. Legs rather short, simple, finely setose ; fore 

 femora nearly straight.

Slender, cylindrical, smooth, and destitute of spines or 

 tubercles ; general colour luteous-buff. Head nearly 

 rounded, convex, with a black stripe on each side behind 

 the eyes ; upper lip dark brown ; lower parts of the mouth 

 and palpi green. Antenna; long and slender ; joints long 

 and thin ; base luteous-buff, gradually becoming dark 

 brown to the tip. Mesothorax about half as long again as 

 the prothorax, both with a slender lateral black line. Teg- 

 mina minute, erect, stipuliform, rounded at tip, incurved, 

 blackish, with a narrow green stripe in front. Wings pale 

 luteous-buff, with a broad marginal border of brown ; costal 

 area pale buff with a greenish' tint, with a broad anterior 

 dark brown border enclosing a pale dash at the base, and 

 followed by a brown longitudinal stripe formed of small 

 square spots in the cells. Abdomen slender, rather dilated
