LEPIDOPTERA. HEPIALID.E. 



HEPIALUS. 



Generic Distinctions. Antennae very short, sometimes slightly 

 serrated ; palpi and maxilla both wanting. 



HEPIALUS SYLVANUS. Orange Swift. This species is 

 orange-colour, with three white lines ; the tipper wings 

 also variegated with chestnut-colour, and a small dusky 

 spot on the disc. 



HEPIALUS HUMULI, Ghost Moth, is pure satiny white, 

 margined with yellow ; the female being entirely of that 

 colour, with streaks of brown on the anterior wings. In 

 this genus the female is unlike the male in colour and 

 markings ; the caterpillars feed on the roots of plants, 

 and, previous to their change, they bury themselves in an 

 oval cell, composed of grains of sand held together by 

 silken threads ; the eggs resemble grains of gunpowder. 

 The H. humuli is sometimes found in June. All the 

 species of this beautiful genus are very local in their 

 habits. 



LEPIDOPTERA. BOMBYCIDJB. 



GASTROPACHA. 



Generic Distinctions. Antennae short, curved, and bipectinated
