LYMANOPODA. 401 



Genus XXIX. LYMANOPODA Westw. 

 Lymanopoda and Sarromia Westw. Plate LXVII. 



Body slender ; wings broad, elongate-triangular, generally of uniform colours, destitute of ocelli, but marked with a 



few minute dots. 

 Head small, very hairy, especially in front. 



-Eye.s prominent, finely haiiy. 



Labial Palpi greatly porrected, being twice the length of the head, and elevated obliquely to the level of the top 

 of the eyes, but slightly compressed, densely clothed with long hairs to the tip ; the hairs on the upper or 

 hinder surface being rather shorter than those of the front. 



Antemice about half the length of the fore wings ; composed of elongated very distinct joints, and terminated by 

 an elongated gradually formed club, concave on its under side, and finely carinated within. 

 Thorax slender, moderately hairy. 



Fore Wings elongate, subtriangular and broad, owing to the length of the hinder margin. Costal margin but 

 slightly arched ; apical angle rather acute. Apical margin slightly convex, nearly t^vo thirds of the length 

 of the costa ; hinder angle rounded. Hinder margin nearly three fourths of the length of the costal. Costal 

 vein strongly dilated at the base. Postcostal vein with the first and second branches arising before the anterior 

 extremity of the discoidal cell, free ; third and fourth branches arising beyond the cell, at an equal distance 

 from its extremity and the tip of the wing. Upper disco-cellular vein very short, transverse, arising at about 

 the middle of the length of the wing : middle disco-cellular of moderate length, the tip extending obliquely 

 backwards towards the base of the wing : lower disco-cellular with its base directed still more towards the base 

 of the wing, but forming a strong angle at a little distance from its origin (throwing off a veinlet into the 

 discoidal cell from the angle) ; the extremity being directed in an oblique curve outwardly, without, however, 

 extending further than the anterior extremity of the cell ; so that the apical outline of the cell is very 

 irregular, its extremity being united with the third branch of the discoidal cell, at a little further distance 

 from its base than the space between the first and second branches ; the third branch being obtusely angulated 

 at the place of junction. Base of the median vein slightly swollen. Submedian vein not swollen at the base. 



Hind Wings large, oval ; the outer margin slightly angulated in the middle in some species ; anal margin entire, 

 and slightly convex. Costal vein scarcely extending beyond the middle of the costa. Postcostal arising just 

 opposite to the precostal (which is nearly straight and directed outwardly) ; postcostal branching at a con- 

 siderable distance from its base. Upper disco-cellular long, arising at a very short distance beyond the base of 

 the branch of the postcostal; its base curved ; its outer part forming, as it were, the base of the discoidal vein : 

 lower disco-cellular short, transverse, slightly oblique ; closing the discoidal cell rather beyond the middle of 

 the wing, and uniting with the third branch of the median vein at about the same distance from its base as 

 exists between the first and second branches. 



Fore Legs (in both sexes ?) extremely minute, hidden among the hairs of the breast. The coxa elongate ; the 

 femur very short, not half the length of the coxa, dilated, the tip hairy on the outside ; the remainder of the 

 foot forming an elongate-oval articulated mass. 



Four Hind Legs moderately long, slender, scaly. Femur clothed beneath with long hairs. Tibia not hairy ; 

 armed with numerous rather long slender spines, scattered over the limb : tibial spurs long. Tarsus also very 

 spiny. 

 Abdomen small, slender. 



This is a very peculiar and interesting group, distinguished by the great length of the brush-like palpi, the form of the discoidal 

 cell of the fore wings, and the singular structure of the fore legs, closely resembling that of the males of Ypthima. There is so much 

 similarity in the position of the minute white spots, as well as in the colouring of the under surface of the wings of the two insects 

 represented in Plate LXVIL* figures 6. and 7., that they have been regarded as the opposite sexes of the same sjiecies ; in which case, 

 from analogy with other buttei-flies in which the sexes vary in their colouring, we should be led to regard the blue individual (fig. G.) 

 as the male, and the brown one (fig. 7.) as the female. I have, however, found the same structure of the fore legs in both sexes, and 

 am thence led to doubt whether these insects are not, in fact, males of two distinct species. At all events the style of colouring in 

 figure 6. is quite unparalleled iii the present family. Several species of somewhat larger size have the hind wings more decidedly 

 angulated along the outer margin, and the middle disco-cellular vein is angulated near its extremity, the outer one being transverse.f 

 This species I was at first disposed to regard as a distinct genus ; but, as their general characters agree with the other species, I have 

 thought it best to suppress the genus Sarromia proposed on Plate LXVII. The species are few in number, and are natives of Bolivia, 

 Columbia, and the adjacent regions of America. 



* Plate LXVII. has been erroneously numbered LXVI. in some impressions. It may be distinguished from the real Plate LXVI. by containing seven 

 smaller figures instead of six larger ones. 



t In other words, the lower discoidal vein in the larger species arises below, and in the smaller ones above, the angle which emits the veinlet into the 

 discoidal cell.
