wings with, veins 3 and 4 long-stalked or coincident, 5 closely 

 approximated at base to 4, 6 and 7 separate. 



Larva sixteen-legged, feeding in spun-up shoots or between 

 joined leaves of the UPt/rtacece. 



This genus is the type of a group which is rather extensively 

 represented in the Australian region, compared with the other 

 groups of the family. The other known genera belonging to 

 this group are Tmetocera, Bathrotoma, and Hendecasticha, the whole 

 being characterised by the possession of a sharply excavated 

 semicircular notch on the stalk of the antennae of male ; the 

 antennte of the female are simple. Tmetocera is the only genus 

 found in Europe, and is distinguished from all the others by the 

 absence of a costal fold in male. Strepsiceros differs from 

 Bathrotoma in the separation of veins 6 and 7 of hindwings, 

 and the position of the notch on the antennae, which is remote 

 from the basal joint ; from Hendecasticha in the twelve-veined 

 fore wings. The genus is subject to variation in the structure of 

 veins 3 and 4 of hindwings, which are sometimes on a long stalk, 

 sometimes wholly coincident, so that there appear to be only 

 seven veins ; and in the palpi, ivhich have often, but not always, 

 a tuft beneath on the second joint ; but these forms are connected 

 by intermediate gradations, and are not available for generic 

 characters. The species are generally small grey inconspicuous 

 insects, with very similar markings. 



There are eleven Australian species known to me, of which, 

 two occur in New Zealand also, and appear to be indigenous 

 there, equally as in Australia. The following is a tabulation of 

 them : 



A. A broad white streak along part or whole 



of costa, 

 1 . Costal streak extending from base to apex. 



a. Costal streak interrupted before middle 9. plinthinana. 

 I. Costal streak entire ..10. obeliscana.
