tlie indigenous ones are characterized by their anterior wiiiirs being 

 brilliant green or bluish-green, more or less spotted with red, and 

 their posterior wings of the latter colour, with a dusky or bluish 

 border. They are gregarious, and inhabit fields and meadows, and 

 may be known from the species of the preceding genus by their 

 elongate simple antennae, which have a curved fusiform club, ter- 

 minating in an acute point. Owing to their uniformity of appear- 

 ance, they have been much neglected in this country; but there are 

 evidently several species which I have attempted to discriminate, 

 but unfortunately I am unable to give so complete an accoiuit of the 

 history of all as I wish, from my former ignorance of their distinct- 

 ness; and I conceive that it would be a dereliction from those 

 principles which have hitherto guided me, were I to pass them over 

 in silence as mere varieties, their distinctions not resting upon the 

 authority of one, but of several specimens, which generally vary 

 considerably amongst each other, each, however, retaining its proper 

 character.

Distinguished from the other indigenous species by the transparency, elonga- 

 tion, and slenderness of its wings, and their markings : the anterior are of a 

 deep-greenish or greenish-blue, with a large obscurely duplex red spot at the 

 base, two others placed rather obliquely on the disc, frequently united, and a 

 fifth towards the apex near thecosta: the inferior are red, with a very slender 

 dusky-greenish margin. 



Var. /3. With all the red spots on the anterior wings vmited into an irregular 

 longitudinal streak. 



The antenniE are much shorter and more slender in this than in either of the 

 following insects. 



CaterpiUar (according to Esper) greenish, with the head and anterior legs black, 

 the rest green : a whitish stripe on the back, and a row of black spots on the 

 sides: it feeds on Trefoil (TrijhUum). The chrysalis is yellowish-white, 

 with dusky back and wing-cases.— Albin seems to have figured the larva of 

 this insect as that of An. Filipendulae. 



I was fortunate enough to meet with this species in great plenty 

 the latter end of June, 1826, in West Horsley-park, Surry: it has 

 not been noticed as a native of Britain; and wore it not from the 

 circumstance of my possessing an extensive series of specimens, 

 taken in the above locality, aU agreeing in material points with
