minute ones of similar colour adjoining the outer edge of the striga, the black 

 being totally obliterated ; a secoad is marked as usual with luteous, hut has 

 only about four minute black dots on all the wings: in fine, specimens have 

 occurred (as may be seen in the British Museum collection) in which all the 

 wings are longitudinally streaked with black ! 

 Caterpillar white, with a luteous lateral line and various rows of irregularly 

 shaped black dots and spots ; it feeds on the currant, blackthorn, &c. :— the 

 imago appears about the middle of July. 



This beautiful insect, according to the communications that I have 

 received, seems to occur in profusion throughout the country. 



Genus CCX. — Melanippe, Duponchel. 



Palpi remote, short, slightly projecting beyond the forehead, slender, acute ; 

 triarticulate, the basal joint shorter, a little curved, second equally robust, 

 terminal very small, acute : maxilJcE long. Antennce slender, simple in both 

 sexes, faintly pubescent within in the males : head small ; forehead slightly 

 prominent : eyes small : thorax slender : wings ample, entire, rounded, par- 

 tially expanded during repose, all terminated by a broad dark interrupted 

 band : abdomen short, slender, and subclavate in the males, with a very small 

 anal tuft; more robust and obtuse, and carinated in the females; annulatedin 

 both sexes. Larva with 10 legs, not tuberculated, with lateral flexuous lines: 

 pupa foUiculated. 



The only indigenous species of this genus is readily known by 

 its pure black and white wings, the proportions of which are so 

 near that authors are divided as to the prevalence of the individual 

 colours, some taking the former, and others the latter for a ground 

 colour, which it appears clear is the most correct view, taking the 

 positions of the markings, &c. into consideration. From the pre- 

 ceding genus it differs by having the palpi remote, acute, the an- 

 tennae slender and not ciliated in the males, the wings bordered 

 with a partially interrupted black fimbria.
