ERYCINID.E. 



are very short, each with a slender ring of white scales at its tip ; terminated by a short, distinct, ovate club, 

 with an obtuse fleshy apex, spoon-shaped when dry. 



" Maxilke spiral, not more than half the length of the antennje ; a considerable portion of the apex fringed 

 with tentacula." — Curtis. 



Labial Palpi slender, porrected nearly horizontally, the tip extending considerably beyond the extremity of the 

 frontal tuft of hairs, and rising to about one fifth of the height of the eyes, clothed beneath with long bristly 

 hairs, shortening to the apex ; basal joint nearly half the length of the second ; third joint minute, oval, clothed 

 with long porrected hairs. 

 Thorax with the tippets, collar, and metathorax very hairy. 



Fore Wings somewhat elongate, triangular. Costal margin nearly straight, except at the base. Apical margin 

 very slightly scalloped, convex. Veins arranged as in Zemeros, except that the lower disco-cellular vein 

 is united to the third branch of the median vein at a little further distance from its origin than in that 

 genus. 



Hind Wings subovate, rather angulated at the anal angle. Apical margin rounded, and very slightly scalloped. 

 Costal vein not extending beyond one third of the length of the costa. Postcostal vein with its branch arising 

 at a considerable distance from the base of the wing, the branch extending only to about two thirds of the 

 length of the apparent costal mai'gin. Upper disco-cellular vein short, almost longitudinal, forming the base of 

 the discoidal vein, arising considerably nearer the base of the wing than tlie branch of the postcostal vein : 

 lower disco-cellular vein three times as long as the upper one, oblique, slightly arched, uniting with the third 

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



Fore Legs of the male very minute, simple, and densely clothed with hairs. Femur very short, scaly, and pilose. 

 Tibia longer, producing very long scaly hairs. Tarsus comiX)sed of a single lanceolate joint. Fore Legs of the 

 female nearly three times as long as those of the male, perfect, scaly. The femur longer than the tibia. 

 Tarsus also slightly longer tlian the tibia, articulated as in the hind legs. 



Four Hind Legs short, scaly. Femur of the middle pair longer than in the hind pair, clothed beneath with 

 rather long hairs. Tibial spurs very minute and slender. Tarsus armed beneath with fine spines. Claws 

 slender, porrected, sickle-shaped, acute at the tip. Pulvillus simple and distinct. 

 Abdomen small, and of moderate length. 



Catespillar elongate-ovate, somewhat onisciform, hairy. 



Chrysalis short, with the head obtuse, destitute of angulated protuberances, setose, attached by the tail, 

 and girt round the middle of the body with a thread. 



The Duke of Burgundy Fritillary (the name given by our collectors to the type of this genus) is the only European representative 

 of the present family, and is one of the most interesting of our native insects. It is generically nearly allied to Zemeros ; but the 

 elongated, acute, very hairy palpi, the pilose eyes, the strongly clavate antenna;, and the curious arrangement of the veins of the hind 

 wings, separate it from all the adjacent genera. Looking at the series of European, or, still more restrictedly, at our British, butterflies, 

 this insect fills an important situation between the butterflies with girt chrysalides, having fully developed feet in both sexes, and those 

 butterflies in which the fore feet of the males are brush-like, all of which inhabiting Europe have simple suspended chrysalides. This 

 position was assigned to the genus with admirable tact by Dennis and Schiffor Miiller, in the IViener Verzeichniss, nearly a century 

 ago. The following observations by Hiibner on the species comprise all that is known of its habits. The eggs are found solitary, or in 

 pairs, on the under surface of the leaves of Primula veris and elatior ; they are almost globular, smooth, shining, and pale yellowish 

 green. The Caterpillar feeds on the leaves. Its head is roundish, heart-shaped, smooth, shining, and bright ; ferruginous black only on 

 the mouth and about the eyes: its body is almost oval, Init long, depressed, and set with rows of bristly warts; the other parts are 

 clothed with feathery hairs. On the back, at least from the fourth joint to the tail, there is a black dot on each joint, and on the sides 

 similar, but less distinct spots. The colour is pale olive brown ; its feet are rusty brown ; the spiracles black ; claws and belly whitish. 

 It moves very slowly ; rolls itself up when disturbed, and remains in that state a long time. Soon after the middle of summer it 

 becomes a Pupa, not only fastening its body by the apex, but also by spinning a cord about its middle. In this state it remains until 

 the end of the following spring. The caterpillar throws oft' five skins before it assumes the chrysalis state, and its appearance at 

 different ages varies considcrabh-. 



The species from India introduced by ]Mr. E. Doublcday with doubt into this genus, under the name of Nemeobius? Demeter, 

 appears to me to belong to the following.
