EIOTIC MICROLEPIDOPTEEA. 



marginal series of white dots on costa towards apex and termen : 

 cilia whitish, three grey lines, base grey barred white on dots. 

 Hindwings and cilia light grey. 



S. India, Coimbatore, April {Fletcher) ; one specimen. 



Pycuodytis irrigata, n. sp. 



S $ . 13-14 mm. Head whitish-fuscous sprinkled grey. Palpi 

 whitish, second joint irrorated dark fuscous except apex, terminal 

 joint wdth dark fuscous submcdiaii band. Thorax whitish-fuscous 

 mixed dark fuscous and ochreous. Abdomen light ochreous-grey. 

 Fore wings elongate, narrow, cosla gently arched, apex pointed, 

 termen extremely obliquely rounded ; light brownish-ochreous, 

 veins streaked whitish-ochreous and more or less strongly edged 

 dark fuscous irroration ; a-black dot beneath costa at I, one beneath 

 fold below this, and one above fold rather posterior; stigmata 

 black, plical slightly before first discal : cilia whitish-ochreous, 

 basal half spotted fuscous. Hindwings 6 and 7 stalked ; pale grey ; 

 cilia w^iitish-ochreous. 



Madagascak, Antananarivo : four specimens. 



Thyrsostoma glaucitis, Meyr. 



Antennae 6 second joint elongate and considerably thickened, 

 about half second. Thorax sometimes tinged violet-grey. Post- 

 median discal marking of forewings a narrow-elongate spot sur- 

 mounted by two fine cloudy dashes ; a faint whitish spot on termen 

 towards apex. Tibial tufts of scales more correctly termed 

 expanded whorls. 



Besides Ceylon, received from Cooig, Kanara, and Assam ; 

 attached to mango, apparently common. The above corrections 

 and additions are needed to show distinction from the following- 

 species, of which the first two are closely allied to it but easily 

 separable. I suspect these insects of elevating their hindlegs in 

 the manner of SUithmopoda, to which there is some superficial 

 resemblance, and should be glad of definite observations. The 

 genus is allied to Thiotricha, and not to Aristotelia as suggested ; 

 T. pj/htrtis Meyr. is properly referable here. Corrected neuratiou 

 of hindwings: 2-4 parallel, 5 approximated, 6 and 7 long-stalked. 

 To this genus also belongs the European Gaerini, erroneously 

 placed by Stainton in Stathmopoda ; its food-plant, like the mango, 

 belongs to Anacardiacece. 



Thyrsostoma diplobathra, n. sp. 



S ?. 10-11 mm. Head, thorax pearly-white. Palpi whitish, 

 second joint with expanded fringe of very long whitish hairs 

 l)eneath, terminal joint grey. Antenuje S basal joint much 

 elongated and thickened, second joint also much elongated and 

 thickened, | of basal, ciliations 2, Abdomen c^ whitish, dorsally 

 grey towards base, $ grey. Forewings very narrow, widest near 

 base, thence pointed to acute apex ; grey with strong violet- blue
