Genus XV. ZERITIS. 



Zeritis Boisduval, Blanchard, E. Douhleday. 



CiGAKiTis Boisduval, Lucas. 



Nais Swainson. 



Phasis and Scoptes Eubner. 



Body rather robust ; wings rather small, often more or less scalloped, especially the hind pair towards the anal angle, 

 and generally copper-coloured above, and marked mth silvery spots beneath. 



Antennce rather short, straight, witli the middle joints rather short and sliglitly annulated with white ; terminated 

 by a long gradually formed club commencing at about the middle of the antennaj, solid, not spoou-shaped, 

 obtuse at the tip. 



Labial Palpi considerably elongated, porrected, clothed beneath with moderately elongated scaly hairs ; the 

 terminal joint nearly half the length of the second, moderately slender and finely scaly. 



Eyes oval, very convex, naked. 



Fore Wings moderate-sized, occasionally slightly scalloped along the apical margin. Postcostal vein with four 

 branches ; the first and second arising before the anterior extremity of the discoidal cell ; the third and fourth 

 in the space between the cell and the tip of the wing. Upper discoidal vein arising at a very short distance 

 beyond the discoidal cell : the upper disco-cellular obsolete ; the middle and lower ones very slender ; the latter 

 uniting with the third branch of the median vein at a short distance beyond its origin. 



Hind Wings with the outer margin slightly scalloj^ed. The first branch of the median vein and the subraedian 

 vein often extended into short tails or angulations (most evident in the males). The upper and lower disco- 

 cellular veins very slender, the former arising just beyond the branch of the postcostal, and the latter uniting 

 mth the third branch of the median, just beyond its origin. 



Legs moderately short. The tibia3 and tarsi strongly armed with short acute spines. Fore tibias of the males 

 truncated at the tip, not hooked. Extremity of the tarsus arnaed with a single horny curved acute point. 

 Ungues of hind legs (and of the fore legs of the female) small but protruded, acute, rather dilated at the base 

 beneath. Pseudonj-chia very slender, setose ; pulviUus small and narrow. 



The species of this African genus, like the Chrysophani, arc generally distinguished by the copper or orange colour of the upper side of 

 the wings, wliilst the under side is generally ornamented with patches of silver. The characters given above have been drawn from Papllio 

 Thisbe Linn. (Nais Cramer) and its immediate allies ; but Z. Alpheus differs in the more elongate-triangular form of the fore wings, 

 entire on the outer margin, and the broad red fascia on the upper side of the wings, the fourth branch of the postcostal vein of the fore 

 winws is also wanting; and some of the species (which have been separated luider the name of Cigaritis) have the hind wings more de- 

 cidedly tailed, and appear to approach such species of Amblypodia as Pindarus, Vulcanu.s, Oreas, and Perion (which last will also probably 

 prove to be a native of Africa, and not of Surinam. Mr. Swainson's generic name Nais, being a transposition of the specific name of 

 the type, is rejected as contrary to the recognized rules of nomenclature.
