NEW SPECIES OF AUSTRALIAN CADDIS-FLIES, 



appendages the same colour; eyes greyish black; occiput only slightly swollen 

 behind. Length of hindleg 18 mm. 



Wings: Forewings with a very close and delicate reticulation of pale 

 fuscous on a ground colour of fawn, the costal margin and the space between 

 the aual veins and posterior border less infuscated, and hence appearing paler 

 and more definitely fawn-coloured than the rest. All the main veins medium 

 fuscous, except R, which is much paler, and the anal veins, which are darker. 

 Hindwings pale semi-transparent fawn-colour, the veins slightly darker. 



Text-fig. 3.: Stcnopsychodes hiemalis n. sp., d\ Appendages, a, dorsal view; 

 b t left lateral view, slightly dorso-lateral. Lettering as in Text-fig. 2. 



Appendages: These are on the same plan as in St. montana, but differ 

 in the following points: — Tenth tergite not truncated apically; the longer pair 

 of apoterga excessively slender, only slightly longer than the gonapophyses, be- 

 yond the ends of which their sharply pointed tips diverge widely upwards and 

 outwards; the shorter pair very slender, nearly as long as the penis. Preanal 

 appendages very slender, nearly straight, slightly hairy. Penis subcylindrical. 

 the apex bent slightly downwards, apparently without titillators. The broad 

 lateral processes from the ninth sternite are not so closely appressed to the 

 gonapophyses, and their ventral border carries a definite bulge near the middle. 

 These appendages are shown in dorsal view in Text-fig. 3, a, ventral view in 

 Text-fig. 3, b. 



2. Closely resembling the male in size and markings, but darker. Antennae 

 20 mm. (those of the male are broken), dull reddish brown beneath, yellowish 

 brown above. Thorax and abdomen rather dark brown. Forewing more deeply
