ERYCINID^. 



Genus XXXIX STALACHTIS. 



Stalachtis Hiibner. 

 Neeias Boisduval. 

 Heliconia p. God'. 

 Acr^a p. Perty. 



Body elongated, slender ; fore wings greatly elongated, considerably varied with spots and markings of black and 



white. 

 Head moderate-sized, clothed with fine hairs, and marked with small white dots. 



Eyes prominent, naked. 



Antenmv moderately elongated, slender, not annulated with white ; terminated by along, slender, gradually formed 

 club, incurved at the tip, which is rather acute. 



Labial Palpi varying a little in length in the difiercnt species, slender, compressed, clothed with scaly hairs ; the 

 tip not elevated above the height of one third of the eye ; and in some species not, in others the terminal joint, 

 visible in front of the head from above; this joint being slender and elongate-ovate. 

 Thokax robust, but small. 



Fore Wings large, elongate-ovate, or elongate-subtriangular. Tlie costal margin arched ; apical angle rounded. 

 Apical margin entire, and more or less convex, being considerably so in St. Calliope, and much less so in St. 

 Phlegia. Inner margin varying in length according to the form of the wing, nearly straight. Costal vein 

 extending beyond the middle of the costa. Postcostal witli three branches ; tlie first and second arising before 

 the anterior extremity of the discoidal cell, and the third about half way between the cell and the tip of the 

 wing. Upper disco-cellular obsolete: middle one arising conjointly with the upper discoidal, and forming, with 

 the lower disco-cellular, a moderate curve, united with the third branch of the median vein at about the same 

 distance from its origin as exists between the first and second brandies. 



Hind Wings short-ovate, entire. Costal vein extending about four iifths of the length of the costa. Postcostal 

 curved at its base, extending into the disc of the wing, nearly opposite to the precostal, branching at a con- 

 siderable distance from its origin. Upper disco-cellular vein arising a little before or a little beyond the origin of 

 the branch of the postcostal ; forming, with the lower disco-cellular, a slight curve, and uniting with the third 

 branch of the median vein at a moderate distance beyond its origin. 



Fore Legs of the male very minute, and very densely clothed with long hairs. Fore Legs of the female much 

 longer, and articulated as in Limnas. 



Four Hind Legs long, slender, scaly. Tibiaj and tarsi armed beneath with very minute spines. Ungues and 

 their appendages minute, concealed above by the thick coating of scales of the produced upper extremity of 

 the terminal joint of the tarsus. 

 Abdomen greatly elongated, especially in the males ; shorter and more ovate in the females. 



Caterpillar cylindrical, rather thickened; the sides of the body armed with fleshy elongated filaments, 



or thick spines. 

 Chrysalis entire, finely hairy; head obtuse. 



Tlie insects of this genus are amongst the largest of the present family, nnd present so great a resemblance to the Heliconian butterflies 

 that thev were united with them by the older writers, and even by G'ulart. They are structurally very closely allied to Limnas, but 

 are distinguished at once by their long slender antennae, and spotted markings of their wings. 



The Caterpillar of 11. Calliope, according to Stoll, is of a reddish fulvous colour ; the head black, marked with a reddish Y-shaped 

 line : the first segment with two patches of velvety black, and a row of black dots down the back. The sides of the body are clothed 

 with long hairs; one on each side of each segment apjieaiing larger than the rest. The Chrysalis is whitish, with several rows of black 

 dots, and clothed with fine hairs. The Caterpillar of H. Euter|)e, according to the same author, is green with a reddish head, and with 

 eight elongated fleshy filaments on each side of the body, following the scguiL ut which bears the third pair of legs. It feeds on the Musa, 

 and remains in the chrysalis state only ten days.
