small ochreous-tinged plate. Feeds in a light silken tube amongst spun- 

 together leaves of Genista in garden hedges. Pupa in a thin firm white 

 silken cocoon in same place. Probably the larva is polyphagous, the food- 

 plant not being native. 



Occurs commonly at Christchurch, Nelson, Dunedin, Wellington, and 

 Auckland, in January, and again in March and April ; during the latter 

 months I also found the larva? feeding, from which imagos emerged in 

 April. The species flies abundantly over its food-plant for a short time 

 about sunset, and I have also taken it at light. It is to be regretted that I 

 should have fallen into the error of adding to the already too numerous 

 synonyms of the species, misled by its extreme variability. I was also 

 wrong in imagining the existence of a thoracic crest, often a difficult char- 

 acter to observe ; the species is therefore not referable to Pyrgotis. 



5. Pkoselena, Meyr. 



Thorax smooth. Antenna? in male shortly ciliated. Palpi moderate, 

 porrected, second joint triangularly scaled. Forewings in male with costa 

 simple. Hindwings broader than forewings. Forewings with 12 veins, 7 

 and 8 separate, 7 to hindmargin. Hindwings with 8 veins, 3 and 4 sepa- 

 rate at origin, 5 parallel or approximated at base to 4, 6 and 7 stalked. 



Differs from the preceding genera by the separation of veins 7 and 8 of 

 the forewings, from Harmologa by the absence of the costal fold, from 

 Tortrix by the separation of veins 3 and 4 of the hindwings. I have 

 thought it best to widen the original definition of this genus, (founded on a 

 single species), by not insisting on the parallelism of veins 3, 4, 5 of the 

 hindwings ; these differ much in relative direction, but the differences are 

 probably incapable of definition, and insufficient for generic distinction. 

 As thus established the genus includes two described Australian species, 

 (I have a third unpublished), and three are now added to it from New 

 Zealand, of which number one was formerly erroneously referred to Tortrix. 



These three species may be thus tabulated : — 



A. Forewings whitish-grey . . . . . . . . . . . . . . 7. asgistana. 



B. ,, ochreous. 



1. Forewings unicolorous . . . . . . . . . . . . 9. siriana. 



2. ,, with basal third much paler than remainder . . . . 8. hemionana. 



7. Pros, aspistana, n. sp. 



Parva, alis ant. albido-griseis, macula basali trianguloque costse magno 

 castaneis, fusco-marginatis ; post, griseis. 



Male. — 13 mm. Head, palpi, and thorax whitish-grey, somewhat 

 mixed with fuscous (but damaged). Antenna? whitish-grey (?). Abdomen 

 whitish-grey. Legs whitish-grey, anterior and middle pair suffused with 

 dark fuscous except at apex of joints. Forewings oblong, rather narrow,
