 This species is the most widely distributed of the genus ; its biblio- 

 graphy is very much more extensive than above given, if the economic 

 literature be taken into account. The larva is omnivorous. 



Genus Hvphantria Harris,

 Head small ; tongue weak and short ; palpi mere rudiments. An- 

 tennae moderate in length, shorter and simple in the female, bipectinated 

 in the male. Legs short and rather slender. Spurs of middle tibise very 

 short and weak ; posterior tibiae with small terminal spurs only ; anterior 

 tibiae with a small spine each side of tip. Claws simple. 



Primaries with 7 to 10 on a stalk, 10 very close to the base of the 

 stalk ; 7, 8 and 9 close together near the apex ; 3, 4 and 5 from the end 

 of the median ; 4 and 5 from the same point, or on a short stalk, 3 very 

 close to 4. 



Secondaries, 8 from subcostal past the middle ; 6 and 7 on a long 

 stalk from end of subcostal ; 4 and 5 from the same point from end of 

 median j 3 somewhat remote from 4. 



Despite its superficial resemblance to Spilosoma this is really a strong- 

 ly marked genus.
