(Hypena h uinnli. — Harris.) 



Order, Lepidoptkua; Family. PvHALiDiE. 



[Feeding iipcm the leaves of tlie hoinine ; a naked, green, 

 fourteen-legged worm, dotted with black and marked with 

 from two to four white stripes, and having the head dotted 

 with black.]

color, green, with Avhite and dark lines and black dots. 



These caterpillars (Fig. 254) in walking arch up their backs 

 like the span-worms, and when javrcd from the leaves they 

 usually hang suspended l)y a silken thread. They are very 

 sprightly, frequenth' leaping sidewise to a distance of several 

 inches when touched. When fully grown they are about an inch 

 long. They then desert the plants and secrete themselves 

 beneath the fallen leaves, etc., or enter the earth and form 

 small cells in which to pass the pupa state (Fig. 254a). 



The perfect moth (Fig. 254) exi)ands about an inch and 

 three lines. The fore-wings are of a didl brownish color, 

 marked with darker spots and coal-black elevated points. 

 The hind wings are pale dusky brown. 



There are at least two broods of these worms produced in 

 one season, and these are to be found from May to September. 

 The manner in which these insects pass the Winter is not 

 known ; but the last brood of moths, which appear in Septem- 

 ber or October, probably hibernate, and deposit their eggs in 

 the following Spring. This species is reported as occurring 

 in this State, but I hiivc never seen a siiecinien of either larva 

 or perfect insect.
