176. Ant. barysoma, n. sp. 



Minor, alis ant. griseis, ochreo albidoque mixtis, punctis disci 

 plerisque circulatim dispositis saepius obsoletis nigris ; post, 

 saturate fuscis. 



$. 15-16 mm. Head, palpi, antennae, thorax, abdomen and 

 legs greyish-fuscous ; hairs of posterior tibiae paler. Forewings 

 elongate, posteriorly somewhat contracted, costa gently arched, 

 apex round-pointed, hindmargin very obliquely rounded ; fuscous- 

 grey, mixed with ochreous and grey- whitish scales ; six or seven 

 small black dots arranged in an irregular oval in disc, often 

 partially obsolete : cilia whitish-ochreous. Hindwings dark fuscous ; 

 cilia whitish-ochreous, with a dark fuscous line near base. 



The unusual form of the forewings gives this species a rather 

 singular facies. 



Common at Deloraine, Tasmania, in November, amongst rushes 

 (Juncus) in swampy places, flying rather actively and apparently 

 naturally by day ■ also taken by Mr. G. H. Raynor, near Mel- 

 bourne. 



Some remarks on the action of Tannin on Infusoria. 

 By Harry Gilliatt, Esq. 



In the April number of the " Royal Microscopical Society's 

 Journal," appeared a paper by Mr. Waddingfcon* on the action of 

 Tannin on the Cilia of the Infusoria, which must have aroused 

 considerable interest in the minds of those Microscopists who pay 

 special attention to this group. 



Mr. Wadding ton says : — 



" In trying the effect of various Chemicals on Infusoria — princi- 

 pally Paramoecium Aurelia, I was led to use a solution of tannin, 

 or tannic acid ; and I was surprised to find that the immediate 

 action of this chemical was to render the cilia visible without any 

 manipulation of the light.
