flattish on the crown. The antennte arc slender, with the 

 joints numerous and very indistinct. The surface of the 

 body is very finely villose. The prothora.\ has an im- 

 pressed line down the middle of the anterior half. The 

 nietathorax has the sides nearly parallel. The abdomen 

 is slender and cylindrical, the terminal segments very much 

 swollen ; the eighth segment rounded beneath at the sides 

 and emarginate towards the ninth joint, which is rounded ; 

 the terminal ventral segment is very concave and swollen, 

 rounded at its extremity, which extends beyond the ninth 

 dorsal segment ; the anal styles are elongated, deflexed, 

 incurved, obtuse at the tips, and setose. The tegmina are 

 minute, spiniform, black, with a fine luteovis line at the 

 base in front. The wings are pale brown ; the costal area 

 pale luteous, with the spaces enclosed by the small trans- 

 verse veins brown. The legs are reddish brown, slendtr, 

 simple, and moderately long ; the fore femora slightly emar- 

 ginate at the base, pitchy brown beyond the middle.

Most nearly allied to A. affine, De Haan, but larger, 

 and with comparatively larger wings in the female ; the 

 thorax and costal veins of the wings differently coloured. 

 Long, slender, of equal width throughout, smooth, very 

 finely villose, destitute of spines or tubercles, of a brownish 

 luteous colour varied with dark brown spots and streaks. 

 Head slightly convex, with a fine impressed longitudinal 

 line in the middle of the hind part : ou each side behind 

 the eyes is a slender luteous line, and several others less di- 

 stinct. The antennte are of moderate length and slender. 



The prothorax is about two-thirds of the length of the me- 

 sothorax ; the surface of both is smooth, and varied with 

 dark longitudinal stripes on a paler ground, the central dark 

 line being the broadest, and interrupted in the middle by 

 a small bilobed pale oval spot. The tegmina are small, 

 erect, and spiniform. The wings of the male are of mo- 

 derate size, those of the female reaching to the middle of 

 the fourth dorsal segment of the abdomen ; comparatively 

 narrow, of a very pale brown colour, slightly darker along 

 the outer margin, with rather darker longitudinal veins ; the 

 costal margin brown along the anterior portion, the hinder 

 portion irregularly clouded with whitish and brownish-buflF 

 markings ; the median vein simple. The al)domen long 

 and simple, varied with dark longitudinal marks ; the three 

 terminal johits very much swollen in the male, those of the 

 ventral surfiice large, extending beyond the ninth dorsal 

 segment ; the apex bent upwards, obtuse at the tip, and 

 slightly emarginate, widely gaping, enclosing the dilated 

 male organ terminating in an acute point ; the anal styles 

 thick and deflexed, dilated, oval, pointed, setose. The 

 operculum very compressed, extending to the extremity of 

 the ninth dorsal segment, widely gaping at the extremity, 

 exposing four slender curved appendages dilated at the 

 base. Four fore legs simple, short ; fore femora slightly 

 sinuated at the base ; hind pair longer, slender, scarcely 

 setose.

Obs. It is only from conjecture that I have given the 

 two insects above described as the sexes of the same 

 species. 



18. (251.) Aschipasma iBfumatiun. 



Pallidum, brunneo-maculatum, alarum area antiea hya- 

 lino brunneoque tessellata (maris plaga viridi), postica in- 

 fumata. 



Ascepasma infumatum, Charpentier, Orth.Descript.T^lAX, 

 Hub. In Java. 



From Charpentier's figures, this species seems to ap- 

 proach nearly to A. Daunus, but has the costal area of 

 the wings more spotted (and marked with a green patch in 

 the males) ; and also to have the legs more variegated. 



19. (252.) Aschipasma Sei-villeanum. 



Viridi-fuscum ; capite et thorace lineis nigris longitudi- 

 nalibus plus minusve distinctis notatis ; tegminibus minutis.
