Type porphyrojjk, Lower. (P. L. S., N.S.W., 42, 1898.) 

 This genusi is formed to receive the above. I formerly 



placed it in the genus Arrhodia, but it is properly referable to 



the GeoinHrida. 



The original specimen is still unique. 



SELIDOSBMIJXK. 



SCIOGLYPTIS TRISYNEURA, n. Sp. 



Male, 26 mm. Head, palpi, thorax, and abdomen grey- 

 whitish, thorax with moderate bifid posterior crest, face with' 

 obtuse horny projection. Palpi long, 2 densely haired 

 beneath. Antennae greyisih, bipectinated pectinations 6 (apex 

 broken). Legs greyish-fuscous, posterior pair whitish, 



posterior tibice dilated enclosing tuft of hairs. Forewings 

 elongate, triangular, termen obliquely and gently rounded ; 

 10, 11, and 12 free, nearly parallel; grey- whitish, obscurely 

 iiTorated with fuscous; fovea well de\ eloped, somewhat 

 striated beneath ; markings fuscoiis, very obscure, lincd^ 

 scarcely traceable; first dentate, from costa at one-fourth to 

 innermargin at one-fourth, dot like on margins; median line 

 nearly straight, followed by a parallel line, more oblique, 

 somewhat beyond; a distinct discal dot; a very dentate,, 

 oblique line from five-sixths costa to anal a.ngle, emitting a- 

 streak from above middle to below apex ; a row of dots along" 

 termen; cilia gre3^ish. Hindwings with termen rounded; 

 white on basal two-thirds, rest of wing light fuscous ; a small 

 fuscous discal spot; median shade faintl}^ indicated, distinct 

 on innermargin ; an obscure waved subterminal line, distinct 

 on innermargin ; dots along termen and cilia as in forewings. 



An obscure looking insect; the horny frontal prominence, 

 crested thorax, neuration (which may vary) and dilated pos- 

 terior tibiae are, I hope, sufficient characters to recognise it. 

 It is nearest lifhhiojm, Meyr. The antennae are unfortunately- 

 damaged ; the crested thorax, although not in accordance with 

 the genus, are too trivial to separate the species generically, 

 especially when the variations of iieLu^al characters of the genus 

 are considered, consequently I prefer to place it here. 



Arltunga, Central South Australia; one specimen in 

 No\ember. 



Pachytyla, n. g. 



Face somewhat rounded, w4th appressed scales, palpi 

 moderate, porrected, thickly scaled, terminal joint very short. 

 Antennae in male bipectinated to apex. Thorax not cietced. 

 Abdomen ^\^th lateral crests. Femora glabrous, posterior
