MORPHEIS. 255 



discoidal cell. Lower disco-cellular rising at about one third of the length of the discoidal vein, oblique and 

 short, beino- about as long as the basal part of the third branch of the median vein, where it is united to it. _ 



Fore Legs of^the male? small, pectoral. Tarsus minute, slender, oblong, apparently consisting of a single joint, 

 and very hairy. 



Hind Legs moderately long. 

 Abdomen small, extending as far as the extremity of the anal vein of the hind wmgs. 



Larva and Pupa unknown. 



The species on which this genus is founded possesses so much the general appearance of some of the species of Euterpe that 

 M Boisduval described it in his " Species " as a memher of that genus, without any expression of doubt. The structure of the fore legs 

 at "once however, removes it from the family to which Euterpe belongs. It bears considerable affinity to the genus Syncliloc, but is 

 !at once' dlstinn^uished by the hind wings having the discoidal cell closed, and by the second In-.anch of the subcostal vein of the fore 

 winrrs bcinfr inserted beyond the insertion of the first discoidal vein. It bears a miniature kind of resemblance to Papiho Seinirc Cr. 

 aiipi)olvte'z);w;v/), a species nearly allied to the genus Diadema. On the under side the fore wings are coloured as above, but paler at 

 tlie tips and with dark streaks; and the hind wings are much varied with white spots, and buff, yellow, and brown shades, with slender 

 longitudinal black lines between the veins. 



The only species which I have yet seen belonging to the genua inhabits Chili and Brazil.

Genus XLI MORPHEIS. 



MoRPiiEis IliJbn. (Papilio NymphaUs Lemonias dubia Morpheis.) 



Body rather long and hairy, not robust. 



Head rather small, hairy, without any decided frontal tuft. 



Eyes naked. 



Labial Palpi porrected to more than twice the length of the head, slightly ascending, not reaching above the 

 level of the middle of the eyes ; alike in both sexes, compressed, very hairy, especially beneath ; terminal joint 

 nearly half as long as the preceding, slender, and with short hairs above and long ones beneath. 



Antenna' not quite half the length of the fore wings, rather robust, and terminated^ Ijy a large, very compressed, 

 oblong-ovate club, deeply grooved within at the base, the outside clothed with white scales. 

 Thorax rather small, rather hairy, especially in front. 



Fore Wings elongate subtrigonate. Anterior margin rather rounded. Outer margin about two thirds of the 

 length of the anterior, rounded externally, with the portion occupied by the extremity of the discoidal veins 

 more evidently rounded. Costal vein rather strong, reaching a little beyond the middle of the costa. 

 Subcostal vein slender ; its first branch arising at about one third of its length from the base of the wing ; 

 second branch arising a little beyond the middle ; third branch arising at a little distance beyond the second ; 

 fourth branch arising at about the distance of three quarters of the length of the wing. The vein between the 

 first and second branches is rather deflexed, emitting the upper disco-cellular nearer to the first than to the 

 second branch. This upper disco-cellular is very short and transverse, but distinct; the middle disco-cellular 

 is also short and curved ; and the lower disco-ceUular is longer, straight, and running obliquely, so that it 

 closes the discoidal cell at about the middle of the wing, uniting with the third branch of the median vein at a 

 little distance from its origin, the latter being but little curved. 

 [find Wings subtriangnlar. The costal margin nearly straight. Outer margin regularly rounded. Anal inargin 

 forming a groove for the reception of the abdomen. Precostal vein bent at a nearly right angle, its tip 

 reaching the margin of the wing. Branch of subcostal vein emitted near the base of the wing. Discoidal 

 vein arising at a little distance beyond, without any upper disco-cellular vein ; lower disco-cellular wanting, so 

 that the discoidal cell, which is very narrow, is open. Branches of the median vein almost .straight. 

 Fore Legs of the male minute and pectoral, clothed with long black hairs ; the tarsus reduced to a single short 

 joint. Fore legs of the female nearly twice the length of those of the male, scaly. The tarsus as long as the 

 tibia, well articulated, five-jointed; the tips of the joints within armed with two short spines; terminal joint 

 destitute of ungues and pulvillus and much shorter than the preceding. 

 Four Hind Legs moderately long, slender. The tibiaj with a double row of short spines on the inside ; tibial
