THAIS. Thais Hypsipyle. 



general colour of this butterfly is brown, with the exception of a moderately broad 

 greenish band along the centre of the wings. In the female the band is nearly colourless, 

 and the light patch on the upper wings is transparent. The under parts are nearly of the 

 same colours, except that the outer edges of the tails are fringed with a narrow line of 

 glittering white, like burnished silver. The insect is a native of Siam and Java. 



Lastly, we come to the prettily-marked Thais, one of a genus of Papilionidse, which 

 can always be known by peculiar markings of their wings. The colours are, in all the 

 species, yellow, black, and red, and the wings are edged with a series of bold festooned 

 marks. The inner edges of the hinder wings are deeply scooped, as if to permit free 

 motion of the abdomen. The larva of this insect feeds on the Aristolochia ; its form is 

 short and cylindrical, and its surface is covered with short spines and hairs. It has the 

 forked filamentous appendage of the neck. The colour of this species is rather complicated, 

 but may be described as follows : On the upper surface, the first pair of wings are yellow, 

 marked with black, and the lower pair are also yellow, but have a row of crimson spots 

 just within the black festoons. On the under surface, the upper wings are paler, and are 

 marked with four red spots along their edge ; the under wings have also red spots, but 

 the festoons are deeper and more angular than on the upper surface. 



WE now come to another family, called the Pieridse, which may be known at once by 

 the manner in which the inner edges of the hinder wings are folded, so as to form a kind 

 of gutter in which the abdomen rests. In all these insects, the colours are comparatively 

 sober, the upper surface being generally white and black, and the under surface sparingly 

 coloured with red and yellow. To this family belong our common white butterflies, 

 together with the well-known Brimstone Butterfly, the harbinger of spring ; all the 

 Marbled Butterflies, the Orange-tip, and the now scarce Veined-white, which last 

 mentioned insect belongs to the typical genus. The EPICHAEIS is almosf wholly white 

 and black above, a slight tinge of rose-colour appearing on the lower edge of the hinder 

 wings, and being due to the rich orange-red spots on the under surface. All the colour 

 is concentrated upon the under surface of the lower wings, the groundwork of which is
