222 THE ENTOMOLOGIST. 



fed the first week in July, and then rests in a nearly straight 

 position, slightly bent at the ventral claspers,and slightly arched 

 at the 6th segment, the head being porrected on the same 

 plane as the body : when annoyed it doubles itself up and 

 falls from its food-(3lant, feigning death for a very few seconds, 

 and then making its escape with celerity. Head quite as 

 broad as the 2nd segment ; face flattened and without any 

 conspicuous notch on the crown : body narrowest at the 2nd 

 segment, and thence gradually increasing in breadth to the 

 anal extremity ; 5th segment with four dorsal warts, arranged 

 in an exact quadrangle ; 6tb segment small, with a transverse 

 belt of six warts or humps, the lateral ones being smaller and 

 much less conspicuous than the others ; there are very small 

 dorsal warts on each segment following the Gth ; the 12th 

 segment has a slight but very perceptible protuberance on 

 each side ; there are, moreover, a number of minute warts on 

 all parts of the body, and each of these emits a short bristle ; 

 the vential surftice of each segment, after the 4th, has two 

 very small approximate warts placed transversely, and on the 

 Gth segment these are fused into one. Colour of the head 

 dingy brown, reticulated with darker markings, and having a 

 white bar across the face ; the antennal papillae are also 

 nearly white: colour of body of the same dingy brown as the 

 head ; there is a broad gray medio-dorsal stripe extending 

 from the head to the 6ih segment, where it vanishes between 

 the two medio-dorsal protuberances ; this stripe is somewhat 

 constricted on the .3rd and 4th segments, but dilates on the 

 5th, to be again suddenly constricted on the Gth ; this stripe 

 has on each side a slender margin of pure white, and on its 

 disk are numerous slender rivulet markings ; on the dorsal 

 surface of the 7th, 8th, 9th, lOlh and 11th segments are two 

 approximate light gray markings placed transversely ; the 

 dorsal warts are white, and so also is the outside of the ven- 

 tral claspers, as well as a slender white sinuous stripe ex- 

 tending from thence towards the head ; the ventral is 

 much paler than the dorsal surface, and, in addition to nume- 

 rous delicate rivulet markings, has two almost white inter- 

 rupted stripes extending nearly its entire length : full-fed the 

 10th of July, when it spins a very slight web under leaves on 

 the surface of the ground, and changes to a pnpa : the moth 

 appears towards the end of the same month, also in August.
