3. Adonis Fab. — Wood,/. 66.— Argus Don. 4. 143. 1 ? .— Ceronus Hiib. 



Male 18 lines, brilliant azure blue, posterior margins of the wings with a 

 line black line, with a few black and white dots next it in the inferior ; 

 cilia white spotted with black : underside of superior wings gray, inferior 

 ochreous-brown, spotted similarly to P. Corydon, but stronger and the 

 scarlet spots in the under wings more brilliant. Female 16 lines, similar 

 on both sides to P. Corydon, but very variable, the disc and a large por- 

 tion of the under wings being sometimes blue. 



I received a variety from Mr. Leplastrier, with all the discoidal 

 spots excepting the central one ^'anting on the underside, and which 

 I formerly thought might be Hiibner's P. Dorijlas, but it has spot- 

 ted cilia. I have observed that all such varieties have a crumpled 

 place in one of the wings, wiiich leads me to imagine that they have 

 been punctured whilst in chrysalis, and that has altered the fluids, 

 and suffused or obliterated the spots. 



This brilliant insect is confined to chalky districts, and is always 

 found, the beginning and middle of August, in the same places, and 

 often in company with the last: there is a brood also the beginning 

 of May. I once met with it in vast profusion on grassy southern 

 slopes of the downs near Dover. 



The caterpillar feeds on the Trefoil. 



4. Dorylas Hub.pl. 60. f. 2S9— 291.— Wood, pi. 673 ? 



17 lines. Male brilliant azure blue, with the posterior margins black ; 

 cilia white. Female purplish-black, inferior wings with 5 scarlet spots 

 near the margin : beneath ochreous brown ; superior wings with a cordate 

 black spot surrounded with white, beyond it 6 ocellated spots in a trans- 

 verse line, 5 scarlet spots near and 6 whitish ones adjoining the posterior 

 margin : inferior wath a white cordate spot in the centre surrounded by 

 about a dozen black ocellated dots, posterior margin and a large patch at 

 the centre whitish with a line of 7 or 8 black dots with scarlet spots above 

 them. 



I have never seen a British specimen of this insect : mine is the 

 curious variety already alluded to. 



5. Icarius £sp.?— Amandus Hilb.i 59-/. 283—285. 



Male 18 lines, brilliant blue, superior wings with the costal edge and su- 

 perior margin black as well as 6 spots along the margin of the posterior 

 wings ; cilia whitish immaculate. Female 19 lines, brilliant blue with a 

 broad fimbria on the costa and posterior margin as well as a spot at the 

 apex of the discoidal cell and the ncrvures black ; posterior wings with 

 the abdominal margin black, 6 black spots near the posterior margin and 

 a long one next the superior wings : beneath cinereous ; wings bluish at 

 the base, with an oblong black spot ocellated with white on the disc and 

 a transverse line of 7 beyond it with 6 obscure ones near the posterior 

 margin : inferior with two black spots ocellated with white near the base, 

 a long bent one on the centre, a curved line of 8 beyond it and 7 near to 

 the posterior margin with scarlet spots above crowned by black As. 



I have never seen a British specimen of this butterfly. Mr. Wood's 

 figures represent very different insects to Hiibner's, and are pro- 

 bably varieties of the following species.
