 obtuse, then roundly widened so that the hinder part is broadest, the posterior 

 margin moderately but widely emarginate ; the surface flat-convex, strigose and 

 punctate, with a smooth, subcarinate, narrow median line (these characters almost 

 obsolete in the oldest examples). Length, 4, breadth, 3 mm. 



Of the insect the antennae (fig. 1) taper from base to apex ; Ist and 2nd joints 

 in length subequal ; 3rd nearly as long as 1st and 

 2nd together ; 4th much shorter ; 5th to 8th con- 

 secutively shorter ; 8th deeply gradate on one side 

 at the apex ; all, except the Ist, with few hairs. 

 Tibiae (fig. 2) three times longer than the tarsi, the 

 latter with parallel sides, apex obtuse ; claw small ; 

 the four ordinary capitate digitules short. The 

 figures were kindly made by Mr. G. S. Saunders. 



The snow-white cottony ovisac is very large, 

 varying according to extent of oviposition, but in the 

 most mature individuals attaining 10 mm. in length 

 and 6 mm. in breadth. It is much wider than the
