Subfamily V. PORITIIN^. 



Egg. According to Mr. Doherty the egg is " hexahedral " in 

 shape, " like a truncate pyramid, nearly twice as long as wide, with 

 two vertical and two sloping sides, the former trapezoidal, reticu- 

 late near their upper edges ; the latter and the apex nearly square, 

 delicately reticulate. Along with those of Liphyra brassolis, 

 Westw., they are the most remarkable eggs in the family." 



Larva. Unknown. 



Pupa. That of one form P. harterti is described by Mr. Doherty 

 as follows : " The chrysalis somewhat resembles those of the 

 Erycinidcr. (= Nemeobidce) and strikingly illustrates the singularity 

 of the group. It is suspended, not girt, but rigidly inclined to the 

 surface of the leaf. It is less compact in form than that of other 

 Lyccenidce, and is studded with bristles. Of these a number on 

 the side of the head are white, with two black ones on each side 

 on the top of the head and one black one on each side of the 

 thorax above the thoracic angle. The second, third and fourth 

 abdominal segments have each a lower white and an upper black 

 bristle, approximate laterally, while the last segments have a 

 number of white lateral and of black subdorsal ones. The ground- 

 colour is ochreous, much marked with dark, especially on the upper 

 surface of the abdomen, each segment having a black line near its 

 hind margin, except the first, which has two black spots dorsally. 

 The wing-covers are veined and bordered with brown." 



Imago. Of moderate expanse and characteristic colouring. On 

 the upperside the males are mostly velvety black, with streaks of 

 blue: the females brown with similar streaks, and generally in 

 addition some yellow markings. In both sexes of all the forms 

 veins 5, 6 and 7 of the fore wing are closely approximate at base. 



Within our limits two genera of this subfamily occur. One, 

 Zarona, is remarkable in that the forms arranged under it have 

 in the fore wing all twelve veins present. The genus Pseudo- 

 dipsas, Felder, of which one form, P. cephencs, Hewitson, is given 

 from India, has only a superficial likeness to the forms of the 

 Poritiince. Its venation clearly shows its affinity to the Theclince.
