not very well marked structually considered; but very evidently character- 
ized by a peculiar style of maculation which renders them easily recog-. 
nizable. The table on p. 41 of Vol. VI is:perhaps as good an ee 
ment for their distinction as can be at present devised. . 
Colaenis has the discal cell of primaries closed, of secondaries open; 
the tibize are not spinose. The wings are elongate, rather narrow, re- 
minding one of Heliconta, tawny in color above and beneath; without 
silvery spots. ue ; 
Agraulis has the same general appearance; but is much wider wing- 
ed, the primaries still drawn out at apex; tawny in color, spotted above 
with black, and beneath marked with elongate silvery blotches on sec- 
ondaries and at apex of primaris, The tibia are spined, else the genus 
is structurally like the preceeding. A. vanillae is very common in the 
Southern States. + 
Argynnis is very largely represented in our fauna, and very many 
species have been described. They are usually moderate in size, tawny 
in color, maculate with black above, and usually with silver on second- 
aries beneath. ‘The maculation is all after the same type, and a_ species 
once seen. all other representatives of the genus can be recognized at a 
glance. The discal cell of both wings is closed. 
Euptoieta resembles Argynnis in maculation above, but lacks the 
silvery spots beneath. The primaries are broader, produced at apex, and 
somewhat excavated above middle of outer margin. ‘The discal cell of’ 
secondaries is open, . . 
Diadema is large, with some resemblance to Danais; but the discal 
cell of secondaries is open. ‘The primaries are fulvous above, black. to- 
ward apex and with an oblique white band crossing this dark space. 
Melitaea and Phyciodes substantially agree in maculation, and are 
often considered identical. Above, they resemble miniature Argynuzds; 
but the discal cell of secondaries is open. The species referred to Afeli- 
faea have the apices of primaries sumewhat more produced than those 
referred to Phyctodes. 
Eresta and Synchloe are very near to Melitaca. and are by some con- 
sidered identical with it. The former has somewhat more elongate wings 
and more abruptly clavate antennz, the latter is slightly excavated at 
outer margin of primaries below apex. These genera are very unsatis- 
factorily distinguished. | 
In Vanessa and Grapta the discal cell of both wings is open; ‘the % 
_primaries are angulated, the,secondaries shortly tailed. The. species re-
