35G SATYKID^. 



Thorax short, oval, very hairy. 



Wings with the disc on the upper side clothed with short hairs. 



Fore Wiiig.s elongate-triangular. Fore margin arched ; apical angle variable. Apical margin generally slightly 

 convex, or nearly straight ; inner angle rounded. Inner margin nearly straight. Costal vein dilated at the 

 base, extending a little beyond the middle of the costa. Postcostal vein slender, with its branches fi-ee ; the 

 first arising a little before, and the second quite close before, the anterior extremity of the discoidal cell ; 

 third branch arising at about two thirds, and extending to the costa at about five sixths, of the length of the 

 wing; fourth branch arising just opposite to the extremity of the third, and extending to the apical angle. 

 Upper disco- cellular vein extremely short, transverse, arising at about the middle of the fore margin of the 

 wing: middle disco-cellular of considerable length, curved, its tip extending outwards: lower disco-cellular 

 about equal in length to the middle one, straight, very slightly oblique, uniting with the third branch of 

 the median vein, at a little distance beyond the middle of the wing ; the third branch forming an angle at 

 the place of junction, which is at the same distance from the origin of this third branch as exists between the 

 second and third branches. Median vein swollen at the base. 



Ilind Wings large, triangularly ovate. Costal margin emarginate at the base, regularly curved. Apical margin 

 variable, but generally -\nth the three branches of the median vein more or less prolonged at the tips, so as to 

 cause the portion next the anal angle to be more or less scalloped or dentate. In T. Mermeria the outer 

 margin is rounded, but in T. Chelys tlie extremity of the costal margin is more dilated ; so that the costal 

 vein, which, in the former, extends only about two thirds of the length of the costa, reaches to its apex in the 

 latter. Precostal vein much curved, and directed outwardly from the body. Postcostal vein arising just 

 opposite to the precostal. Upper disco-cellular vein twice as long as the space between the two branches of 

 the postcostal vein ; outer disco-cellular still longer, less oblique, and uniting with the third branch of the 

 median vein at about half the distance from its base as the length of the outer disco-cellular itself 



Fore Legs of the male small and very hairy. The femur and tibia of about equal length ; the former with a 

 thick terminal brush. Tarsus about two thirds of the length of the tibia, exarticulate, as hairy as the tibia. 

 Fore Legs of the female considerably longer than those of the male, and thickly hairy throughout (but less so 

 than in the male) ; the articulations of the tarsus being hidden by the hairs, and only indicated by a few 

 small spines on the under side seen through the hairs. 



Four Hind Legs long, scaly. Tibia as long as the femur, slightly curved. Tarsus as long as the tibia ; the 

 joints very distinct, scaly. Tibial spurs moderately strong. Claws very much curved and acute, slightly 

 dilated at the base. Paronychia very minute and membranous, bifid; the outer division very slender; 

 the inner one triangular. Pulvillus obcordate, leathery. 

 Abdomen elongate. 



Catespizlar rather short, setose; head conical, and much elevated, hairy, a pair of long acute spines 

 directed backwards on the back of the middle of the body, and two pairs of similar spines towards the 

 extremity of the body, which is furnished with two long very hairy tubercles or points. 



Chrysalis elongate-ovate, witiiout conical protuberances ; head terminated by two conical points. 



This is a group of large-sized Satyild;e, natives of the hottest jiarts of South America, remarkable for the dull uniform brown colouring 

 of the upper surface of the wings; the only variation in this respeut consisting in the broad orange margin to the hind wings of the 

 species selected to illustrate the genus ( T. Chrysogoue, PI. LX. f. 4.), and an indistinct fulvous patch beyond the middle of the fore 

 wings in T. Echo. In T. Mermeria, which may be considered as a good type of the genus, and which has supplied the above generic 

 characters, the male has the fore wings terminating in a point ; whilst in the female they are prolonged into a narrow appendage at • 

 the tip. T. Mermeria has the margin of the hind wings scarcely scalloped ; whilst T. Chelys has them even more strongly dentate than 

 T. Chrysogone. The middle of the wings, in the majority of the species, on the under side, is separated from the base and apex by two 

 dark nearly straight bars, beyond which is a row of minute round dots, which are dilated into ocelli in T. Andromeda. In a few 

 species, T. Chelys, &c., the under side of the wings is more clouded and irrorated, and the dark streaks more irregular. 



The caterpillar represented by StoU [Siippl. to Cramer, Pap. pi. 7. f. 1.) is so unlike all the known larvae of the family, that we 

 should be inclined to doubt its accuracy, were not the scrupulous care of the author so well known. The pupa reminds us of that of 

 some of the Morphldaj; as do also the spines on the back of the caterpillar. If there be no mistake in this respect, we have here an 

 additional proof of the intimate relation of the Morphida; and Satyrlda;.
