RANDLE: Calephelis borealis Biology Vol.7, nos.3-4
was about 250 feet distant from and about 35 feet above a permanent stream. In this location C. borealis was first discovered in 1937. Subsequently this butterfly was found by SMALLEY and the author in a few other widely separated places in the same type of habitat.
Records from the study area showed that the flying period for this latitude was from somewhat after the middle of June to somewhat after the middle of July. In 1950 and 1951 C. borealis was seen in numbers on June 27, and a few worn specimens were taken on July 28. Thus the total period in which imagoes were flying must have been a month and a half. Generally speaking, adults are inactive butterflies, sitting on leaves of weeds and shrubs for long periods of time basking in the sun with wings outstretched. The males are the more active, sometimes flying up in the air to dispute the intrusion of another male or some other winged insect. On two occasions the author watched individuals crawl around to the undersides of leaves when hard pressed and at other times they dropped low into the cover of vines on the ground or into tall grass. Smalley has observed imagoes on the underside of foliage on at least twelve occasions. Upon alighting they usually spread out their wings horizontally.
Careful observation of this area during all seasons indicated that C. borealis hibernated in the larval stage, probably in the sixth instar. Never was this insect seen flying before mid-June nor after the first week of August. No larvae of anywhere near pupating size were found in the fall.

ACTION ON NOMENCLATURE AT COPENHAGEN
The Colloquium on Zoological Nomenclature at Copenhagen, Denmark, which was arranged by the Secretary of the International Commission on Zoological Nomenclature (see Lep. News 7: p.32) was able to deal with the entire agenda of seventy items when it met in August just prior to the start of the Fourteenth International Congress of Zoology. THE OFFICIAL REPORT OF THE COLLOQUIUM IS BEING PUBLISHED IN BOOK FORM AND WILL BE AVAILABLE IN NOVEMBER. SUBSIDIZED IN ORDER TO PUT IT WITHIN REACH OF EVERY TAXONO-MIST, THE PRICE WILL BE ONLY 75t (5 SHILLINGS). ORDERS WITH REMITTANCE MAY BE SENT IMMEDIATELY TO THE INTERNATIONAL TRUST FOR ZOOLOGICAL NOMENCLATURE, 41 QUEEN'S GATE, LONDON, S.W. 7, ENGLAND. Every taxonomist should have this important reference booklet.
The Copenhagen Congress, in unanimously adopting the Report, advised authors to apply the decisions to their work as soon as the Report is published, although these decisions will not formally come into force until they have been embodied in the revised International Code for which publication will necessarily require considerable time. Lepidopterists interested in nomenclature, and disturbed over the violent controversy which followed the 1948 Paris Congress, will be pleased to learn that the draft of the revised Code will be published in order to allow nomenclature specialists everywhere to review it very carefully before the final issuance of the revision.
