terior margins produced backwards. The terminal plate of 

 the operculum triangular, about one-third the length of the 

 basal plate. Colour brown, with minute black punctations. 

 Length 15mm. (thorax 11mm., postabdomen 4mm.), the ratio 

 of the length to the breadth being as 11 to 1. 



Hah. Auckland ; found in a tube. 



The tube in which this animal was found is about ^in. long, 

 and appears to be part of the hollow stem of some plant. 

 Whether the presence of the animal in this tube is accidental 

 or habitual is uncertain, but the short legs and strong antennte 

 seem to favour the latter supposition. 



The description given above is mainly taken from ]Mr. 

 Thomson's description, but I have rearranged it and added to 

 it to_ some extent. He describes four joints in the peduncle and 

 two in the flagellum of the antennae. In the peduncle there 

 seem to be five joints, but the first is very short, as it usually 

 is in the Idoteidce, and hidden in a dorsal view by the head. 

 In the flagellum I can only make out a single joint — a flagellum 

 of a single joint is, in fact, given as one of the generic characters 

 of Cleantis. 



Judging from the description this species is very close to 

 Cleantis (jrannlosa, Heller, from St. Paul's, but from a tracing 

 of Heller's figure in " Reise der Novara," pi. xii., fig. 2, kindlv 

 made forme by Mr. R. M. Laing, it is evident that the legs iii 

 that species ure much longer than in G. tuhicola. 



Akt. XXIII. — Descriptions of New Zealand Lepidoptera. 

 By E. Meykick, B.A., F.E.S. 



[Read be/ore the PJiilosophical liistUute of Cantcrhury, }th November. 



I GIVE here descriptions of the whole of the New Zealand 

 species of the three following groups: viz, Bomhijcina, 

 Siiliingina, and Hypsina. They are remarkable for tlieir 

 very small number, and for the absence of any specially 

 characteristic or peculiar forms. The}' prove with certainty 

 that the New Zealand fauna of these three groups is entirely 

 of comparatively recent growth, and is also of solely Australian 

 origin. Considering the powerful flight of many species in 

 these groups, and their relative abundance in Australia, it is 

 perhaps a matter for surprise that a larger number have not 

 found their way across. One Australian species which I have 

 not included hereafter — Cossiis Uturatus, a large insect, of 

 which the larva feeds in the trunk of trees — was once taken In
