series consists of eight spines, and eacli medio-dorsal spine is 

 slightly in advance of that next to it on each side ; the other 

 series of eleven spines each; the 12th and 13th segments 

 have each but two spines. Colour of the face velvety black, 

 but adorned with many paler markings, two of which, ori- 

 ginating on the crown, pass obliquely down the face to 

 each side the clypeus. General colour of the body gray, 

 interspersed with red-brown ; there is a broad medio-dorsal 

 stripe of pure white, commencing on the 7th and ending on 

 the 12th segment in an obtuse point; the last segment has 

 also a large white spot on each side. Spiracles exactly in- 

 termediate in situation between the 2nd and 3rd lateral series 

 of spines, black, surrounded with white, the white again with 

 black, and finally the black with red-brown ; the space below 

 the spiracles delicately reticulated with gray ; the spines 

 which emanate from the white stripe are also white; those of 

 the 3rd or lowest lateral series, also those of each series as 

 far as the 6th segment inclusive, pale brown ; those of the 

 other lateral series from the 7th to the extremity, are white at 

 the tips and pale brown at the base : ventral surface black, 

 irrorated and reticulated with gray and red-brown : legs black 

 and red-brown : claspers red and gray. When full-fed it 

 spins a little hillock of white silk on one of the ribs or on 

 the petiole of the hop-leaf, or on the stem of the hop-plant, 

 or on the hop-pole, or even sometimes on a twig in a neigh- 

 bouring hedge, and, attaching itself thereto by its posterior 

 claspers, it hangs head downwards, and is transformed to an 

 angulatcd pupa ; the head is deeply notched, and the two horns 

 or ears, containing the palpi, are distant, pointed and curved 

 towards each other at the tii)s ; the back of the thorax has a 

 central elevation laterally compressed and very thin ; the 

 sides of the thorax have two blunt protuberances ; there is a 

 deep dorsal excavation between the thorax and abdomen ; 

 the back has three series of raised points, and on each side 

 are two such series ; the points on the medio-dorsal series 

 are small and inconspicuous, thuse of the next series on each 

 side large and prominent ; the first of the lateral series is 

 above, the second below, the spiracles; both are incon- 

 spicuous; the sides mf ^he abdomen, at its junction with the 

 thorax, are much bulged, iriaking this the broadest part of 

 the })upa ; the anal segment is long and slender, and
