instances. The number of specimens examined is indicated in each instance 

 after the description, but, in the case of the commoner species, these are 

 really a selection from a much larger number not retained. I have examined 

 also a small collection from the Otago Museum, forwarded to me by Pro- 

 fessor Parker. 



The following is a tabulation of the five families represented ; under the 

 head of each family is given a tabulation of the genera comprised in it. 



la. Hindwings with 7 veins 5. Ennomidce.

2a. Vein 8 of hindwings connected with 7 near transverse vein . . 2. Larentidce. 

 2b. ,, ,, ,, „ free, or very shortly anastomosing with 



7 near base. 



3a. Vein 11 of forewings separate . . . . 3. Boletobidcs.

4a. Areole double . . . . . . . . . . . . 4. Lyrceidce. 



4b. ,, single 1. Acidalidce. 



1. AGIDALIDM. 

 Antennae of male not pectinated. Forewings with vein 11 rising out of 

 10, areole simple, 12 free. Hindwings with 8 veins, 8 free or touching 

 7 near base only. 



Hardly represented in New Zealand ; of the two species found, one is 

 very abundant in Australia, whence it has doubtless immigrated, the other is 

 not yet known from elsewhere, 

 la. Veins 6 and 7 of hindwings separate . . . . . . . . . . 2. Acidalia. 



lb. ,, ,, ,, „ „ ,, from a point or stalked . . . . 1. Theoxena. 



1. Theoxena, n. g. 

 Palpi moderate, triangularly scaled, porrected. Antennae in male bicili- 

 ated with long tufts of cilia (5). Forewings with vein 6 from below 9, 

 7 from angle of areole, 10 out of 9 above 7, 11 anastomosing shortly with 9, 

 12 free, closely approximated to 11 on areole. Hindwings with veins 6 and 

 7 from a point or short-stalked, 8 free, closely approximated to 7 from base 

 to near transverse vein. 



1. Theox. scissaria, Gn. 

 (Panagra scissaria, Gn., E.M.M., v., 43.) 

 Male. — 23-25 mm. Forewings narrow, hinclmargin rather strongly 

 sinuate ; dull white, slightly sprinkled with dark fuscous ; a curved dark 

 fuscous median streak from inner margin near base almost to apex, sharply 

 defined above, suffused beneath ; a black dot in disc, and a row of dots on 

 hindmargin. Hindwings elongate, narrow, apex broadly projecting ; white ; 

 a blackish dot in disc, and a row on hindmargin. 

 Constant, and very different from anything else. 



Christchurch, and towards foot of Mount Hutt (Mr. E. W. Fereday) ; a 

 plain-frequenting species, occurring in January ; ten specimens.
