 irregular blotch, and ejecting the frass through a hole at the end. Light green 

 with yellow head and cervical shield; at maturity developing three brilliant wine 

 red longitudinal stripes. Cccoon made of a liit of epidermis folded lengthwise.

15. SYNALLAGMA Busck 



Palpus with third segment about half 

 as long as second and smoothly curved. 

 Antenna with scape elongate. Fore wing 

 lanceolate, with apex drawn out into a 

 strongly sickle-shaped hook, and the outer 

 margin below it nearly erect. Eleven 

 veins; R, lost, R 4 and R- stalked, running 

 to costa, M, free, ending at the apex, 2d A 

 strongly forked at base, 1st A doubtful. 

 Hind wing half as wide as fore wing, 

 lanceolate ; fringe twice as wide as mem- 

 brane, with all veins preserved; Sc and R 

 approximate at base, R and M t connate, M 3 

 and Cu! connate, M 2 free, with the cell open 

 below i, Cu 2 well separated. Fore wing 

 with slight raised tufts. Maxillary palpi 

 apparently absent. Hind tibia? with short 

 bristles above. 



This genus is of very doubtful position; 

 perhaps it is Heliodinid.
