Wet-season, 3 3, 15th, 16th, and 19th November, 1896. The extreme dry-season form is T. kelskamma, Trimen. Mr. Marshall writes respecting this species as quoted in the introduction to the present paper. 94. TERACOLUS EIONE, Boisd. 3 6*, wet-season phase, Tugela Biver, 23rd October, 5th, 11th, 12th, and 13th November ; § $ , 2nd, 10th, and 14th November. Intermediate phase, 3 2 J 22nd October; 3 3, 28th October, 2nd, 3rd, and 5th November. Mr. Marshall labels some of the specimens " T. evagore " and others " T. phlegetonla^ others, again, " evagore-phlegetonla." T. evagore is undoubtedly the dry-season phase of the Arabian T. yerburyi (both having been bred from one batch of larvae by Capt. Nurse, who, however, followed me in incorrectly calling the dry phase T. nouna). T. phlegetonla is a species common to Western Africa and the South; it is the wet-season form of T. antlgone, and differs from T. elone in having the base of the primaries broadly lemon-yellow on the under surface; this character is, however, confined to the wet phase of the species. In my judgment three of the examples obtained by Mr. Marshall should be referred to T. antlgone. 95. TERACOLUS ANTIGONE, Boisd. Intermediate phase, 3 6, Tugela Biver, 22ud October and 9th November, 1896. These examples correspond with my T. frlga, but do not show the dry characters so strongly on the under surface: one of them is marked as " intermediate " and two are marked " dry." It is inconceivable that wet, intermediate, and dry forms of one and the same species should be flying together, all three being in equally good condition, excepting in an unusually dry and hot climate in which no rainy season could be said to exist. 96. TERACOLUS EXOLE, Beiche. 3 , Tugela Biver, near Weenen, 2500 feet, 16th November, 1896. This is labelled as T. omphale, and it may perhaps be an extreme development of that species in which all three phases show a well-defined wet-season upperside pattern : at any rate it is a tolerably distinct form, T. exole, Beiche, = acte, Felder, being the wTet form, T. roxane the intermediate, and T. hybrldus (part) the dry. 97. TERACOLUS OMPHALE, Godart. 3 3, Tugela Biver, 27th October, 12th and 14th November; intermediate phase T. omphaloides, 27th October; dry phase T. theogone, Malvern, 3 3, $ $ , 6th, 7tb, 10th, 11th, and 15th August, 1896. |
