NYMPHALINAE: THE GENUS EUVANESSA. 387 



brood of larvae ; also to ask why it is that the butterflies are so much less 

 abundant in tlie spring and in niidsununcr than in the autumn as to have 

 entirely escaped the notice of many collectors ; to direct attention to the 

 question of the number of broods in southern New England, and finally to 

 request observers to note how soon after eclosion the autumn generation 

 seeks its winter quarters ; all facts regarding swarms of this species are 

 worth publication.

 On this my glory ! see the grace I the size ! 



These brilliant hues are all distinct and clean.

Imago (53 : 4). Head pretty large, densely clothed with a bushy mass of long and 

 short hairs. Front well rounded, tumid, protuberant beneath, broader than high, of 

 just the breadth of the eyes; upper edge bluntly rounded and protuberant in the mid- 

 dle, falling rather abruptly into the transverse pit of the antennae; lower edge broadly 

 rounded, almost docked. Vertex moderate, very tumid, projecting very considerably 

 and throughout its whole length above the level of the eyes, very broadly rounded 

 behind, in front projecting Avith curved sides deeply and rather sharply into the space 

 between the antennae, where it is deeply sunken and connected with the front by a 

 narrow bridge. Eyes pretty large, full, sparsely pilose with pretty nearly uniform 

 long hairs. Antennae inserted very slightly indeed in advance of the middle of the 

 summit In deep, nearly connected pits, their interior bases separated by a space equal 

 to the width of the autennal stalk, and their exterior closely croAvded upon the margin 

 of the eyes ; they are about half as long again as the abdomen, consisting of 44 or 45 

 joints, the last eleven or twelve of which form a very ol)long, ovate, cylindrical club, 

 about two and a half times as broad as the stalk, four and a half times as long as broad, 

 the extremity very bluntly conical, the last three or four joints entering into the diminu- 

 tion of size, and successively turned a little more outward, so that the outer edge of 

 the club is nearly straight to the tip, while the inner is broadly rounded ; terminal joint 

 minute, furnished along the under portion of the inner side with a delicate triple carina, 

 continuing indistinctly over a portion of the stalk. Palpi moderately stout, fully three 

 times as long as the eye, compressed, curved outward above, the terminal joint two 

 and a half times shorter than the penultimate, the whole furnished sparsely above and 

 beneath with very long, bristly hairs, directed in a vertical plane and heavily clothed 

 with somewhat erect scales.
