PIERINAE: CALLIDRYAS EUBULE. 1055 



ever ; they are always wanting on that part of the fore wing which is covered by tlie 

 hind pair when the wings are natnrally expanded ; towards the base very many short, 

 carved, yellowish, delicate hairs. Fore wings : at the extremity of the discoidal cell is 

 a transverse, compound spot, conspicuous in the $ , not infrequently reduced to a dash 

 in the ^ , consisting normally of two confluent spots, the upper and smaller traversed 

 by the transverse portion of the lowest subcostal nervure and equalling the base of 

 the lowest subcostal interspace in width, the larger bearing the same relation to the 

 vein closing tlie cell and tlie subcosto-median interspace; the nervules and even the 

 creases of tlie wing frequently break these up into smaller spots but these relations 

 are never wholly obscured; the spots are of a salmon brown (usually in the ^), or 

 pinkish brown (usually in ?), the centre more or less enlivened with silvery (usually 

 in (J) or dull silvery (usually in $) scales and the whole edged rather broadly (espec- 

 ially in $ ) with dark brown scales, although the brighter brown scales of the interior 

 of the spot not infrequently pass tliis barrier, especially exteriorly. The other spots 

 of the wing which are, however, occasionally obsolete wholly or in part, consist of 

 a clustering or of clusterings of sprinkled pinkish and blackish brown scales into a 

 strongly sinuous series of spots and wavy transverse bars crossing the middle of the 

 outer half of the wing; it consists of two portions : the upper, above the median ner- 

 vure, forms a very strongly bowed or arched series of markings starting from a round- 

 ish spot in the upper subcostal interspace a little within the last branching of the 

 subcostal, and extending nearly subparallel to the costal and outer border to a tremu- 

 lous, transverse, oblique, vague dash in the middle of the subcosto-median interspace; 

 the markings in the upper three interspaces are all similar and equidist.ant, the last 

 being in the middle of the interspace contained between the terminal forks of tlie 

 subcostal ; those in tlie three lower interspaces are also similar to one another and 

 from a nearly continuous broken line; the lower portion of this series consists of 

 markings in the median interspaces similar to, but less oblique than, those in the lower 

 subcostal interspaces subparallel to the outer border and distant from it by a space 

 equal to about one and a half Interspaces ; costal margin very narrowly edged with 

 pink ami the outer margin a little more broadly, and in 9 more broadly than in J , 

 with salmon color, the extreme tips of the nervules dotted with black. Hind wings 

 witli four subparallel, equidistant, transverse series of ill-defined spots and transverse 

 bars and streaks of mingled salmon colored and blackish brown scales, not infre- 

 quently partially and sometimes (In $ ) almost wholly obsolete ; the basal series 

 consists of three small round spots, one covering the base of the united nervures, one 

 just without the costal, midway between its divarication from the subcostal and the 

 origin of the precostal, the third above the costal, a little further beyond the precos- 

 tal ; the second series consists of a transverse streak in the costo-subcostal interspace, 

 midway between the precostal and tip of costal, and next of a row of equidistant 

 small spots often vaguely connected into a streak, running in continuity with the 

 base of the upper subcostal nervule from the middle of the upper half of the cell to 

 the internal nervure ; the third or mesial series consists Urst, of a more extensive 

 streak, rather broad in the middle of the wing in the $ , extending from a little 

 beyond the middle of the upper subcostal nervule to the second divarication 

 of the median nervure, and enclosing the outer half of two slightly unequal 

 roundish oval, silver spots, encircled with blackish scales on a salmon base; 

 the upper is generally the smaller and rounder and longitudinal, placed in the lower 

 subcostal interspace at a little more than an interspace's distance from its extreme 

 base; the other usually follows nearly the direction of the upper half of the vein 

 closing the cell which traverses its middle; below the cell, this mesial stripe con- 

 sists of a usually interrupted V-shaped streak in the medio-submedian and snbmedlo- 

 internal interspaces, starting next the lower median just below the last divarication 

 of the median In the same direction as the upper portion of the mesial series ; it 

 reaches only as far as the middle of the interspace and is then bent sharply baseward ; 

 the fourth or outer series is usually rather indistinct ; it crosses the middle of the 

 outer half of the wing and consists of a series of transverse, sinuous, disconnected
