LIBYTHEINAE : HYPATUS BACHMANII. 761 



dull, tawii}' ones, especially along the inner half; at the sides and below gray, with a 

 mixture of whitish and dull, tawny brown scales and hairs, the former more profuse 

 near the base ; the second joint is also furnished with distant, rather longer, delicate 

 blackish hairs, above as well as below, which are entirely wanting on the apical joint. 

 Tongue very darli luteous at the base, beyond black, the tip luteous. 



Prothorax like the top of the head; rest of thorax witli long hairs, dark brown in 

 front, pale brown along the sides and brownish mingled witli light sea-green above; 

 patagia like the thorax. Under surface of thorax covered with pale brown scales, 

 having a rosaceous tinge and with hoary, brownish and a few blackish hairs. Legs 

 reddish or yellowish brown, the femora covered thickly with hoary hairs, the tibiae 

 and first tarsal joint flecked with frequent whitish scales, the tarsal joints tipped with 

 whitish; spines blackish ; spurs yellowish brown at base, beyond black. 



Wings above blackish brown of various tints marked with orange patches and white 

 spots. Fore wings with two large orange patches, one, occupying the hinder half of 

 the cell, obscure next the base, extending fox'ward a little in the middle of the ante- 

 rior half, the other large, subquadrate, divided by the black, lower median nervule, 

 occupying the lower two-thirds of the lower median, and the wliole of the medio-sub- 

 median interspaces between the origin of the lower median nervule and a point nearly 

 two-thirds the distance from its origin to its tip ; it is separated from the orange patch 

 in the cell only by the median uervure. In the apical half of the wing are the following 

 white markings : a transverse patch extending from close to the costal margin to the 

 upper median nervule, its interior margin straight or nearly so, distant beyond the 

 extremity of the cell by fully the width of the Avhite patch, directed downward at an 

 angle of about 100° with the basal half of the costal margin ; the outer margin of 

 the patch is curved, its convexity outward and strongest below; in the lower sub- 

 costal interspace the patch is twice as broad as the width of the interspace; 

 the two lower uervures which traverse the patch and the edge of that portion of 

 the patch are reddish yellow, those above blackish. There is a squarish, slightly 

 longitudinal spot in the next to the lowest subcostal interspace just beyond the 

 last divarication of the subcostal, and a similar quadrate, transverse patch in 

 the upper median interspace, distant from the outer border by rather more than 

 its own width; the lower spot is edged with reddisli yellow and bears a few scat- 

 tered scales of the same color; the apical half of the costal edge is enlivened 

 by a few grayish scales, which are sometimes more distinct in a delicate touch at 

 the very apex; rest of the wing very dark, rich broAvn, with an olivaceous tinge, 

 deepening into black in a broad, transverse belt between the orange patches and 

 the outer subcostal white spot. Fringe russet brown, darkest at base, interrupted 

 rather broadly at some of the nervure tips and especially at the two upper median ner- 

 vules with pale or whitish. Hind wings quite dark, somewhat slaty brown, paler along 

 the inner border, slightly deepening in tint along a scarcely distinguishable longitudi- 

 nal belt following the lower part of the subcostal uervure. A large, transverse, 

 orange patch occurs just beyond the middle of the wing, deepest in tint and distinctly 

 bordered anteriorly, extending from the middle subcostal to the lower median ner- 

 vule, twice as long as broad, its lower border nearly straight and subparallcl to the 

 outer border, but more distant from it toward the inner border, its upper limit reach- 

 ing the last divarication of the median uervure and in the subcosto-median interspace 

 sending a slight shoot toward the base. Fringe pale yellowish brown, on the lower 

 half with a russet tinge, darkest at the nervure tips, apically palest. 



Beneath : /ore tcmgrs with the whole costal border rather dark gray, the cell dull 

 orange, the inner margin steel gray, the base of the medio-submedian interspace, two- 

 thirds the distance to the base of the first median nervule, dark brown, beyond, as far 

 as the middle of the nervule, dull pale orange, separated narrowly by brownish uerv- 

 ures from the orange spot in the cell and from one at the base of the lower median 

 interspace; the latter, also pale, reaches as far toward the margin as it, but does not 

 attain the upper limits of the interspace; beyond the large orange patch thus formed, 

 the lower outer corner of the wing is lustrous steel gray. The white spots of the
