B^.OTIS. 451 



Genus XXVIII. B.EOTIS. 



BjEOTis JIuhner. 

 Ertcina p. God'. 



Butterflies of small size : wings generally variegated with fascia?, or large patches of light colours on a dark ground. 

 Head small, finely hairy, with a slight tnft on the crown. 



Uyes naked. 



Antenncc about lialf the length of the foi'e wings, slender; joints tolerably distinct; terminated by a moderately 

 robust club, gradually formed, incurved at the tip. 



Lahial Palpi small, compressed, furnished beneath with scaly hairs, ascending obliquely, the tip not visible fi-om 

 above, beyond the hairs of the face, and not reaching above one fourth of the height of the eyes ; terminal joint 

 minute, conical. 

 Thorax small, shortly ovate. 



Foi'c Wings more or less broadly triangular. Costal margin more or less arched; apical angle obtuse. Apical 

 margin more or less convex. Costal vein short, not, or scarcely, reaching to the middle of the wing. Post- 

 costal vein emitting two branches before the anterior extremity of the discoidal cell ; third branch arising at 

 about two thirds of the length of the wing ; fourth branch, when present, arising very near the tip of the wing. 

 Upper disco-cellular vein obsolete : middle disco-cellular arising at about the same distance beyond the second 

 postcostal branch as exists between the first and second branches, slightly curved, transverse : lower disco- 

 cellular rather longer than the middle one, its lower extremity extending more towards the tip of the wing, 

 uniting with the third branch of the median vein at a short distance beyond its origin. Upper discoidal vein 

 arising simultaneously with the middle disco-cellular. 



Hijid Wings snbtriangularly rounded, entire along the apical margin, rather angulated at the anal angle. 

 Postcostal vein arising much nearer the body than the precostal, branching at a moderate distance from the 

 base. Upper disco-cellular short, slender, arising at or close beyond the origin of the postcostal branch : lower 

 disco-cellular very slender (almost obsolete), longer than the upper, uniting with the third branch of the 

 median vein at or but a very short distance beyond its origin. 



Fore Legs of tlie male very minute, slender, moderately clotlicd with fine hairs. Tihia and tarsus of nearly equal 

 length, the latter simple. Fore Legs of the female not one third longer than those of the male. Tarsus slightly 

 longer than the tibia, rather dilated ; the tips of the joints beneath scarcely armed with spines. 



Four Hind Legs long, slender. Tibire of the hind legs rather dilated, almost destitute of spines beneath. Tarsi 

 with tlie joints unarmed with spines at the tips. 

 Abdomen moderately elongate and slender in both sexes. 



This is rather an extensive genus of small but prettily marked and coloured species, agreeing with several of the foregoing genera in 

 the general arrangement of the veins of the wings in many of tlie species, but having the postcostal vein furnished with four liranches 

 in others ; there is, however, so niucli resemblance between tlic two groups in otlier respects, that I do not feel inclined on that 

 account to separate them into distinct genera. I have also added to tlie genus several prettily marked species, distinguished by liaving 

 a fine silver line running quite close to the outer border of all the wings on the upper side ; this is a peculiarity whicli especially 

 characterises the species of the genus Charis, and it is indeed by these butterflies that the two groups are brought into contact. As 

 these silver-lined species, however, differ entirely in tlieir other mai-klngs from the species of Charis, I have preferred arranging them 

 in this position, especially as the female of one of them, B. Trochilia, bears so strong a resemblance to B. Parthenis and Cydias that the 

 three might almost be mistaken at the first sight for varieties of one species.
