hiiehneri Kirby is a synonym); and by A. zambesina (Walker) from Zan- 

 zibar. What is probably a third species is Niidaurelia fclderi of Roths- 

 child, from Bogos, Abyssinia. I'he wings of this species, he states, 

 are " very similar to red varieties oi N'. belina (Westw. ), but without 

 the ocellus on the fore wings, there being only a small square vitreous 

 spot. Another difference is the very broad white border to the ocelli 

 of the hind wings." (Novitates Zoologicte, ii, p. 42, 1895.) 



Larva of A. belina. — Last stage. Head about one half as wide as the body, 

 slightly more than half as wide as the pro'thoracic segment ; deep black, unarmed ; sur- 

 face with groups of from l to 8 microscopic granulations, arranged in irregular rows. 

 Surface of the prothoracic plate rugose, unarmed, but bearing a number of long white 

 hairs. In front of the prothoracic spiracle is a very low flattened tubercle not easy to 

 detect, bearing about eight setiferous warts; lower down above the base of the leg is 

 a low rounded tubercle about the size and shape of the one above, and bearing from 

 5 to 6 minute setiferous warts. 



The body behind the prothoracic segment, including the 9th abdominal seg- 

 ment, is armed with stout black spines, all of the same size, which are inclined 

 backwards, but not cu7-ved, being nearly straight and sharp, and from around the base 

 arise about five long white radiating hairs, some nearly as large as the spine itself. 

 The spines are rather short and small, but yet conspicuous (they are apparently 

 longer than in N'tidaurelia dione and Thyella tyrrkea). 



The spines of the infraspiracular row are acute, black, and only about one half 

 as large as those of the supraspiracular row. A series of still smaller ones along the 

 base of the abdominal legs, becoming larger and more prominent on the legless 

 abdominal segments i, 2, 7 and 8. 



The median horn on the 8th abdominal segment is no longer than the other 

 dorsal spines ; it is very deeply cleft (the largest), in one example much more so than 

 \x\ N. dione ; in the smaller specimen (60 mm. in length) it is no more forked than in 

 A'^. dione). 



Suranal plate large, rounded on the hinder edge ; the surface black, moderately 

 convex and granulated, the microscopic granulations around the edge larger, with 

 scattered very tine setae. Anal legs large, black, subtriangular, with scattered warts. 



Body above and beneath almost entirely covered with dense fungoid pearl- 

 colored oval or polygonal warts, throwing off pearly reflections, and centered with a 

 minute pit. These fungoid warts are more numerous and more crowded than in any 

 other of the genera possessing them. Spiracles black. A reddish flesh-colored dis- 

 coloration on each sideof each thoracic segment, below where the spiracles should be 

 if present, and below the prothoracic spiracle. Thoracic, middle abdominal and anal 

 legs black. Length, 80 mm. 



A Smaller One of Last Stoge. — Length 60 mm. In the smallest of the three 

 larvae the median "horn" or spine is no more deeply cleft than in A', dione. That 

 it is in the last stage is shown by the head being of the same size as in the others. 



The fungoid warts are much less numerous. It also has more hairs arising from 

 the spines, and they are inserted higher up from the base of the spine ; also the 

 spinules are reddish, but in the two other larvae black.
