208 Mr. F. W. Edwards on a 



in addition, at the tip of the labella there are two or three 

 very short blunt " spines," closely resembling the " taste- 

 hairs " which have been described by Wesche" and others in 

 a variety of insects. The labella themselves have a beautiful 

 " honey-combed " structure. 



The outer lamellae of the pupal respiratory horns are 

 somewhat triangular, about half as long again as the 

 breadth of the base, and bluntly pointed. The inner lamella? 

 are a little shorter, rounded at the tip, but not at all tapering, 

 and only about one-third as wide as the base of the outer 

 lamellae. 



The larva? have small spines on their dorsal surface, 

 arranged on the same plan as in E. capensis, though they 

 are much less conspicuous ; there are no spines on the lateral 

 processes. As noticed by Scott in Paltostoma, the number of 

 filaments in the branchial tufts increases with the age of the 

 larva ; the small larva? have three in each tuft, the fully- 

 grown specimens have five. The form of these tufts is the 

 same as in E. capensis. I have seen no first-stage larva?, and 

 cannot therefore say whether these have less than three gill- 

 filaments. The extreme tips of the hairy lateral processes 

 are bifid on the underside, a character which is also to be 

 •noticed in E. capensis, though apparently it does not occur 

 in Paltostoma. 



The spiracles are present in the same positions as in 

 Paltostoma ; they appear simply as chitinous rings. The 

 anal papilla? are subequal in size ; hidden by them, but 

 plainly visible in a mounted specimen, is the anal armature. 



Mr. K. H. Barnard has kindly supplied me with some 

 notes on the seasonal occurrence of E. barnardi in Platteklip 

 Xjrorge. His records are as follows : — 



"3. ix. 1911. Full-grown larva?. 



" 8. x. 1911. Pupa?, imagos. 



"2. i. 1912. 1 full-grown larva, pupa?, 1 imago. 



"5. viii. 1912. Various-sized larva? from 2 mm. to full- 

 grown ; pupa?. 



" 16. ii. 1913. No larva? or pupa?. 



"22. vi. 1913. Larvae 2-3 nun. 



" 2. viii. 1913. Larva? 2-1 mm. A few pupa?. 



" There would seem to be three broods a year at least, but 

 with so many gaps one cannot state positively.'" 



Mr. Barnard has also found E. barnardi " in the suburbs 

 of (Jape Town, at a level above the sea of not more than 

 ,200 ft., in a swiftly-running stream from the mountain, but 

 not in any sense a precipitous mountain-stream ; the larvae 

 and pupae are attached to boulders."
