11 lie SUBFAJIILY LEMONIINAE. 781 



cl;ii)u has been broil by liiin and is suspended by the tail as in Stalachtis, 

 anotlicr genus of tiiis tribe, vvi>ieh he elsewhere speaks of as "not flattened 

 beneatli. and secured rigidly by tlie tail in an inclined position without 

 jrirdinir."' 



Stoir, indeed, figures tlie transformations of Stalachtis calliope ; he 

 represents the caterpillar as cylindrical and slightly depressed, of uniform 

 width throughout, about three and a half times longer than broad ; the 

 head is hardly more than half as wide as the body, rounded and hairy ; 

 the first thoracic segment bears a semilunate shield as wide as the head, 

 and a similar though smaller shield is found upon the last segment, with 

 bhu'k points on the intermediate ones ; the segments are distinctly 

 moniliform and apparently are elevated at the base of slender hairs, 

 longer than the segments, which appear to be clustered to a certain 

 extent in fascicles and which are accompanied, apparently at the substig- 

 matal fold, by a stouter bristle, as long as the width of the body on each 

 segment ; besides this the body is covered with a shorter pile. The chrysa- 

 lis is represented without attachment, but in a perpendicular position head 

 downward, and is described by Stoll' as being attached to a leaf stem by 

 its hinder extremity only by means of a stiff bristle (poll roide), "hang- 

 ing perpendicularly with its head toward the earth, like the spiny 

 caterpillars of the tetrapod butterflies" : the chrysalis has a form very 

 similar, indeed, to that of Nemeobius, similar also in its markings and in 

 being very sparsely covered with long hairs ; a dorsal view is given and 

 the anterior extremity is apparently terminated l>y the prothorax. 



Finally, we have the far more satisfactory illustration of Chrysobia, in 

 the figures given by Edwards, and here we are also able to draw upon 

 our knowledge of the species from specimens kindly sent us for examina- 

 tion by Mr. Edwards. The eggs of two species are figured and described by 

 him, and these as well as those of the third, L. virgulti, he has kindly per- 

 mitted me to see. They are flattened spheroids, broadly domed above, 

 delicately and finely reticulated and bear at each angle of the sharp hexagonal 

 reticulation a delicate filament no longer than the width of the cells. In 

 nais these filaments are more pointed than in palmerii, but do not otherwise 

 essentially difter, though figured and described differently by Edwards ; in 

 virgulti they are as in nais. Such reticulation is common in the Ly- 

 caeninae, but the cells of the reticulation have apparently one distinguishing 

 quality in Chrysobia, which is that from the walls of the cell toward, but 

 hardly to, the centre run low, sharp septae, reminding one very strikingly 

 of the similar feature in coral polyps : very probably this may prove true 

 of all Lemoniinae ; while, as far as I have seen, in the eggs of the Lycae- 

 ninae there is no such radiate arrangement of the walls, though in some, 

 especially in the Lycaenidi, the centre of the floor of the cell may be thick- 

 ened and the thickening run in a radiate direction toward the walls of the
