48 Porina. Specimens of P. despecta and unbraculatu were sent from time to time, and four specincns of a very small form, which may only be small males, or may be the nales of other species.

Porina annulata, n. sp.

This most interesting form was received by me one day with the following particulars : Just returned to Skipper's after a rough trip, which, however, I forgot all about after I caught the moth that I am now sending. When we were up Mount Aurun I thought I saw a large moth with a ringed body Aying quickly about, just off the ground, but I could not lay hands on one. When we had finished chaining up Stony Creek one of these flew up and got tanyled in a tussock right at ny leet. I promptly dropped the net over lim. I do not know if it is rare, but it was only seen above 4.000 ft., on tussockr beds among the gentians." This moth is at once distinguished from the other Porinas by the distinci annulate markings ou the body, the only other at all partaking of this character being P. characterijera, a very much larger moth, probably belonging to a different section of the group. Both the upper and lower wings are semi-transparent. Expansion of forewing, 50 mm.; lower wing, 44 min. The forewinys are sparsely covered with scales, se as to be nearly as translucent as the hind wings of P. des peeta. Antennæ strongly pectinate in the male. Head and thoras yellowish-brown. Abdomen pale yellowisii-grey, with seven or cight black rings, very dis- tinct when fresh, but not so apparent when dry. The forewings are brownish-grey, irregularly covered with markings, the majority of which are spots of an ochire-yellow. interspersed with sinaller white marks. The hindwings are brown-grey, showing a few yellowish spots on the termen. Both wings are bordered with dark reddish brown cilia, longer in proportion than those in P. cornuta.

The yellow spots on the wings and the annulated body afford the best distinctive points for the recognition of the species.

In the specimens described the fore and hind wings are more nearly alike in size than in most of the members of the genus, being as 50 and 44. In my specimen of P. corvinata they are as 82 to 6. In P. dinodes the relation is, however, about 70 to 62. In Porine the variation in size, markings, &c., are so great ihat a long series will be required before any weight, can be attached to the proportionate expansion of the wings.
