 A distinct transverse ridge connecting tubercles of fourth abdominal segment. Phyciodes. 



No such distinct ridge Charidryas. 



A suprastigmatal tui)ercie on the second abdominal segment. A distinct, obliquely transver>e, 

 l)la<'k band upon the wing-cases. 

 No distinct tubercles on the eighth abdominal segment, their place being marked only by 



dark spots Cinclidia. 



Tubercles of eighth abdominal nearly as prominent as on the preceding segment 



Euphydryas. 



Table of the (jenera, based on the ima'jo. 



Middle joint of palpi tapering considerably and regularly in apical lialf; fore tibia of $ very 

 slender and of equal size throughout, at least ten titnes longer than broad. 

 Apical joint of palpi less than one-third as long as the middle joint ; fore tibia of <J scarcely 



shorter than the femur Phyciodes. 



Apical joint of palpi nearly half as long as the middle joint; fore tibia of S nnich shorter 



than the femur Charidryas. 



Middle joint of palpi of nearly equal size throughout; fore tibia of 5 stout and tunud, not 

 more than live or six times longer tlian broad. 

 Fore wing not y.roduced apically, the outer being much shorter than the hind margin; sec- 

 ond superior subcostal nervule arising beyond the cell; last joint of palpus more than 



half as broad, and nearly or quite half as long, as the middle joint Cinclidia. 



Fore wing produced apically, so that the outer margin is scarcely shorter than the hind 

 margin; second superior subcostal nervule arising before the extremity of the cell; 

 last joint of palpus less than half as broad, and scarcely one-third as long, as the middle 

 j<^i»t Euphydryas.

Imago (54 : 2). Head large, furnished, not very abundantly, Avith long, erect hairs. 

 Front scarcely, if at all, inflated excepting in the middle beneath, Avhere it is rather 

 sharply protuberant; nearly half as broad again as high, scarcely as broad as the eyes; 

 upper portion almost flat ; upper border produced rather broadly between the eyes, the 

 produced portion transversely rounded, the border abruptly terminating at the pit of the 

 antennae and not sloping gradually to it; lower border rather produced in the middle 

 and strongly rounded; vertex ratlier large, regularly rounded but not tumid and lying 

 beloAV the upper level of the eyes, scarcely broader than long, the sides straight or 

 slightly concave and narrowing posteriorly, the posterior border squarely docked. Eyes 

 rather large, not full, naked. Antennae inserted with their posterior border in the mid- 

 dle of the front in distinct not deep pits, separated at their base by a space equalling 

 the diameter of the second antennal joint; considerably longer than the abdomen, com- 

 posed of thirty-four or thirty-five joints of which the last eleven or twelve compose 

 the club, which is compressed, cylindrical, increasing very gi-adually and regularly in 

 size, principally by increment upou the outside of the joints, and then diminishing 

 rapidly, four joints entering into the diminution of size, the end being well rounded, 

 the apex slightly conical, the whole club four times as broad as the stalk and three 

 and a half times longer than broad ; beneath with a distinct central carina. Palpi very 

 long and not very stout, almost three times longer than the eye, directed upwaril and
