( 22o ) 



ai)ical line : besides the white snbapical halfmouii, there is a ilitl'use whitish patch 

 at the costal margin between the cell and the first discal line, and another smaller 



one beyond the second discal line. -Hiiidwing: a discal line tonchiiig apex oi' 



cell, narrow, sometimes indistinct in front, another near it, abbreviated or obsolete, 

 a third convex in front, then concave, narrow, and a black line outside the third 

 at anal angle reaching np to ftP ; veins with minute black streaks at extremities. 



Unfli'i'Hitle. Forewing : markings similar to upperside, less distinct, those 



in basal half red, the snbbasal line vestigial, straight streak in apex of cell as on 

 npperside in the direction of R'', snbapical white spot larger and more strongly 

 projecting distad before ST'"', the other Iwo wliite patches restricted to the costal 



margin. Hindwing : lines nenrly as above, Imt blackish brown, interspace 



between second and third, or nearly the whole wing, shaded with white, a short 

 white line before apex, marginal area very faintly shaded with white. 



c?. Tenth tergite broad, sides undulate (PI. XXIV. f. ; apex broken in the 

 only specimen at disposal ; it is apparently cleft or sinuate) ; sternite ])rodnced into 

 a long, slender, cylindrical, slightly club-shaped process. Clasper (PI. XXX III. f. 1) 

 narrowed towards a]icx, ventral margin dilated near base, then eiuarginate ; harpe 

 represented by a proximal, pointed, slightly curved process which stands far apart 

 from the clasjier, the processes of the two sides being close together and visible 

 between the claspers without dissection. Penis-sheath (PI. XXX. f 23) stont, jug- 

 shaped, the ajiical margin produced laterad ; penis-furuiel (p-k) with a short, ventral, 

 cariu.ate process. 



?. Vaginal plate (PI. XVII. f 3) resembling to a certain extent that of 

 l'KCii<locI(nti» jioMica ; aiitovaginal part (arp) mesially folded, a large groove at 

 each side; vaginal orifice ( I') situated between two compressed jirocosscs, which 

 are curved mesiad and are pointed, resembling somewhat a bird's head and breast ; 

 post-vaginal part ijji'p) slightly sunken ]iroximally, the greater ])art membranaceous, 

 scaled.

We have not seen the ti/pe of const n't// lis, but Walker's description agrees very 

 well with this insect, which can easily be distinguished from the other sjiecies by 

 the forewing having three white costal patches, a narrow and straight subbasal line, 

 and a narrow line at the apex of the cell, which line has the direction of HI 



180. Platysphinx stigmatica.

behind (SM'j, the three forming a quite irregular line or baud; another irregular
