c??. Larger than separatus, the lilaclc middle stripe of the mesothoracic 

 tegiila almost merged together with the black upper edge, the interspace between 



these lines being dark brown ; i)ronotum without yellow spots. Forewing washed 



with rnsset on the disc ; uo black lougitndinal line in the apical half of the cell ; 

 black obliqne antemedian band from base of M' to inner margin very prominent, 

 consisting of two lines only, the third pro.ximal line being vestigial between 

 M' and SM^ and not traceable beyond SM-, while in separatus all three lines reach 

 inner margin ; five costal marks (costal parts of five lines, of which the three 

 proximal ones are vestigial) between base and apex of cell, second and third mark 



mnch closer together than the first and second. Distal border of hindwing 



narrower than in separatus, the black median band broad, nearly as wide at R* 

 as the distal border ; fringe with large brown spots. 



Underside similar to that of separaf/ts, rather darker, the forewing and body 

 somewhat washed with russet ; abdomen with a series of black middle spots, of 

 which only the second is large. Body less stout than in separatus, armature of the 

 legs similar, but the spines of the foretibia comparatively shorter. Antenna of d 

 not so stont, that of ? not so obviously clubbed. 



c?. Tenth abdominal sternite narrow at tlie base and broad at the end as in 

 geminus, minutely sinuate. Harpe intermediate between those of (jcminus and 

 separatus, decidedly shorter than in the former, and longer than in the latter. 

 Penis-sheath as in separatus. 



?. As in praelongus (PI. XX. f. 15) with a lobe in front of the vaginal 

 cavity, the lobe not distinctly sinuate. 



Early stages unknown.

Hill. Hyloicus praelongus sp. nov. (PI. XII. f. 1, c?). 



(J?. Closely resembling istar, with which it agrees in structure; decidedly 

 more greyish white, the two black streaks of the mesothoracic tegula clearly 

 separated by a grey intersjiace ; forewing more elongate, coming in shape near 

 that of la?iceolata ; markings as in istar, but the cell with a black apical streak, 

 (SM') marked with a while dash outside the double antemedian line. 



? Vaginal plate (PI. XX. f. 15) hollowed out di^tally, the edges raised, mouth 

 of vagina concealed in ventral view by a sinuate lobe with rounded angles.
