POLYOMMATUS ADONIS. Prats XXXV, Fie. 5. 
In Mr. F. Bond’s Collection is a specimen of this pretty insect which, on the under side, has entirely the 
appearance of a female individual: on the upper surface, also, the two wings on the right side, and the hind 
wing on the left side, are female; but the fore wing is dashed, especially on the anterior half of the wing, with 
longitudinal stripes of the brilliant blue colour of the male.

LASIOCAMPA QUERCUS. Prats XXXV, Fic. 14. 
The specimen here figured is contained in the Collection of Herr Staudinger, of Dresden, and exhibits a 
curious mixture of both sexes, the fore wing on the right side alone being unisexual and of the enlarged female 
size and colour; the anterior half of the fore wing, on the left side, is also coloured as in the female; but this 
wing is small in size, as in the male, and the hind half is curiously mottled with the darker and lighter colours 
of the two sexes; the red brown not so dark as in ordinary males; the left hind wing has the costal one-third 
of the pale female colour, the inner two-thirds being of the richer colour of the male, with two large pale oval 
discoidal spots; the hind wing, on the right side, has the outer two-thirds of the wing coloured as in light- 
coloured males, with four pale submarginal spots ; the inner one-third is of the pale colour of the female, but with 
a red-brown spot opposite the extremity of the body. The antennz are shorter and not so much pectinated as 
in the male; the thorax and base of the abdomen are broad as in the females, but the abdomen is small, conical, 
and shorter than in the male. 
Mr. F. Bond also exhibited at the February meeting of the Entomological Society of London, 1868, another 
specimen of Lasiocampa quereus, with the wings irregularly coloured, with the antenn also apparently irregu- 
larly sexual. 
M. Guénée has also described and figured a specimen of the same species in a memoir, recently published, 
upon certain Lepidoptera in the Museum of Geneva (pl. annex. fig. 8, with details), which exhibits a curious 
mixture of sexual characters. The two wings on the right side, the hind wing on the left side (except a narrow 
pale streak extending from the middle of the disc to the outer margin), and the inner half of the fore wing on 
the left side, are apparently those of the male; but the anterior or costal half of the left fore wing is enlarged 
and pale coloured, as in the female. The body is thick, as in the female; the antennw are intermediate in 
structure between those of the two sexes; and the abdomen was found to contain imperfectly developed eggs— 
the outer organs of generation being also imperfect.

CALEPTERYX VIRGO. PuatTE XXXV, Fie. 15. 
Mr. McLachlan has kindly allowed me to figure from his collection a French specimen of this common 
insect partaking of the markings of the two sexes. The body is green, with the wings very slightly greenish- 
hyaline; the anterior on the right side only slightly and irregularly marked along the middle of the inner por- 
tion with brown spots; whilst the anterior wing on the left side bears a very large dark blue oval patch as in 
the ordinary males. The two hind wings are unicolorous. 
The extremity of the abdomen has been much injured by having a wire passed up the body, the eighth or 
terminal segment alone exhibiting small black horny conical points.
