20ii Ml. F. W. E Kvards on a 



ill ailililion, at the lip of the hihelhi there are two or three 

 verv slioit hliiut "spines," ch)sely roscinbliiii^ the " taate- 

 liairs '■* which have been described by Weschc and others in 

 a variety of insects. The hibella themselves luive a beautitul 

 " lioncy-coinbed " structure. 



The outer laniellie ot' the pupal respiratory horns arc; 

 .•somewhat trianijnlar, about hall' as lon<r airain as the 

 breadth of the base, and bhintly pointed. Tiie inner lamelUu 

 are a little shortoi', rounded at the tip, but not at all taperiii<;, 

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

 lamellae. 



The larvaj have saiall spines on their dorsal surface, 

 arranged on tlie same plan as in /:. capeusis, though they 

 are much less conspicuous ; there are no s{)ineson the lateral 

 processes. As noticed by Scott in L\dtostoma, the number oL" 

 Hhiments in the branchial tut'ts increases with the age of the 

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

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

 same as in K. aqyensis. I have seen no tirst-stage larva?, and 

 cannot therefore say whether these have less than three gill- 

 li laments. The extreme tips of the hairy lateral processes 

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

 noticed in K. capeusis, though apparently it does not occur 

 in Paltostoma. 



The spiracles are present in the same jiositions as in 

 PaltostovKi ; they appear simply as chitinous lings. The 

 anal papiilse 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. bamardi in Plattekiip 

 Gorge. His records are as follows: — 



"iJ. ix. 1911. Full-grown larvaj. 



"t<. X. lyil. Piijiie, imagos. 



"2. i. li)12. 1 full-grown larva, pupai, 1 imago. 



"5. viii. JtU2. Various-sized larva; from 2 ram. to full- 

 giow/i ; pupaj. 



"' IG. ii. 1913. No larvse or pupai. 



"22. vi. 1913. Larvte 2-3 mm. 



" 2. viii. 1913. Larvse 2-4 mm. A few pupae. 



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

 with so many ga|)S one cannot state positively.^' 



Mr. Barnard has also found K. burtiardi " in the suburbs 

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

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

 not in any sense a precipitous mountain-stream ; tlie larvie 

 and pupse are attached to boulders."
