102 Transactions. 



triangular, costa almost straight, termen rounded, waved, rather oblique ; 

 brownish-ochreous, more or less fuscous-tinged ; veins obscurely sprinkled 

 with whitish, and posteriorly also with fuscous ; margins of reniform faintly 

 indicated with whitish ; a curved transverse series of whitish dots on veins 

 at f . each dot preceded and followed by indistinct dark-fuscous dots : cilia 

 light ochreous sprinkled with whitish. Hindwings fuscous, darker towards 

 termen ; cilia ochreous-whitish, basal half suffused with fuscous. 



Waipori, in November and January (Philpott) ; two specimens. Allied 

 to nullifera. 



This is the species erroneously recorded by me as Dasygaster hollandiae, 

 and that name should be struck off the New Zealand list. The specimen 

 originally identified had lost its abdomen, the structure of which is the 

 distinguishing characteristic of Dasygaster, but Mr. Philpott kindly for- 

 warded for examination his only other specimen, and this shows that it is 

 not a Dasygaster at all. The true hollandiae is also (as pointed out to me 

 by Mr. Philpott) a redder insect, without the distinct posterior row of 

 whitish dots ; otherwise it is very similar. 



Andesia pessota Meyr. 



In my revision of the Caradrinina (Trans. N.Z. Inst., vol. 44, p. 95) I 

 referred this (of which I had then no example) with considerable doubt to 

 Hypnotype Hamps. Mr. Philpott has very kindly sent me a specimen of the 

 species, which enables me to correct this reference : it belongs properly to 

 the genus Andesia Hamps. (Cat. 6, 142), and bears considerable superficial 

 resemblance to the single species recorded by Hampson, A. oenistis, from 

 Argentina. This is therefore a very interesting identification. The generic 

 diagnosis should be modified to read, " Abdomen with crest on basal 

 segment." 



Hydriomenidae. 

 Chloroclystis maculata Huds. 



Mr. Hudson has now very liberally sent me a specimen of this apparently 

 scarce species ; it is a true Chloroclystis, and very distinct. Antennae of $ 

 shortly ciliated ; palpi nearly 3. 



Xanthorhoe benedicta n. sp. 



<J$. 22-25 mm. Bather smaller than beata (26-28 mm.); extremely 

 similar to it, but distinguished by presence of transverse-linear black discal 

 mark in pale space of median band of forewings (in beata entirely absent) ; 

 also by hindwings being faintly greenish-tinged, with whitish cilia finely 

 barred with grey, whilst in beata the hindwings have no greenish tinge, and 

 the basal half of cilia is suffused with pale ochreous. 



Christchurch, Dunedin, Invercargill ; five specimens. This species, 

 which is commoner than beata, has hitherto been confused with it by myself 

 and others generally. I am indebted to the acumen of Mr. Philpott for its 

 discrimination ; he has endeavoured for three years to convince me of its 

 distinctness, and has at last succeeded. 



The four points of distinction mentioned above are constantly present 

 together, and thus prove that the differences are not varietal only. The 

 true beata occurs at Lake Wakatipu, Ben Lomond, and Invercargill ; it 

 stands midway between benedicta and adonis. Butler's description and 

 figure, though poor, are sufficient to show which species is intended without 

 doubt.
