8 Watson, Calinaga, Single Genus of a Stib-family. 



there are no longitudinal or horizontal ribs, nor raised lines. 

 Thais and Teinopalpus have less pronounced granulations 

 In the Nymphalidce, Danais and Hestia (of the sub-family 

 DanaincE) have a more or less sugar-loaf shaped ^%^, 

 half as high again as wide, with a series of very regu- 

 larly placed, raised, longitudinal ribs from which, at 

 regular distances, other finer ones run out horizontally, 

 and so circle round the egg. The shell thus has the 

 appearance of rectangular reticulations very evenly dis- 

 posed. Hestia has more symmetrical and more trans- 

 parent intercostal spaces, the term I give to the area 

 between the ribs. 



There is a similarity of these Danaine eggs to those 

 of Pieris in general shape and structure, as will be seen 

 by comparing P. Brassica with the figure of Danais 

 archippus in Packard's " Text-Book of Entomology," 

 (p. 521, fig. 496). 



In the NymphalincE, another sub-family of the 

 Nymphalidce, we get another type of &^^ ; for those of 

 Hypolyninas Salamacis, Bolina, and Anthedon are round, 

 squat, not so high as wide, resting on a flat base from 

 which rise 10 — 12 longitudinal ribs, which terminate 

 abruptly near the top, leaving a bare, almost structureless, 

 area, in the centre of which is the micropyle. There are 

 apparently no transverse ribs, the shell is of delicate and 

 extremely transparent texture. This o.^^ agrees in 

 general characters with that of the British butterfly 

 Hipparchia Tithonus (Westwood's Brit. Butt, pi. B, fig. 29). 

 Hipparchia is one of the Satyrinae, another sub-family of 

 the Nymphalidce. The Qgg of Calinaga is apparently of 

 a similar shape and structure, but it has not perhaps the 

 perfect symmetry of Danais and Hestia; it is not quite 

 so tall, and the intercostal spaces at the top, which are 

 very unequal, remind one perhaps of a Pieris.. as for
