llAEiTAT, — With r. aiifjidalis, and at same dates. 



This species is perhaps the less common, especially m the more 

 northern part of its range, and is readily distinguishable by its smaller 

 size and darker color, and by the dentate transverse posterior and 

 subterminal lines, as well as the black patch below the apex. The 

 reniform here also is black, and often a large blotch, differing in form. 

 In P. an<i)ilnlls the reniform is always oblique from below outward, 

 while in this s])ecies the opposite tendency prevails, though it is by no 

 means constant. The structural and other points of difference have 

 been already pointed out elsewhere. 



Genus C A P I S , Grote.

Head moderate or rather small, front narrower in the male Eyes 

 rather small, though prominent, globose, naked. Tongue moderate.. 

 Palpi oblique or nearly straight, varying in the same sex, well exceed- 

 ing tlie head, but not excessively long. Second joint with rather loose, 

 scaly clothing, directed both upward and downward ; the joint therefore 

 somewhat enlarged at the tip. Third joint less than one-half the length 

 of the second, smoothly clothed, not pointed. Front without a pointed 

 tuft. Anteniiii' simple inthetVmale; feebly ciliate in the male; moder- 

 ate in length. Body moderate, thorax proportionately small; abdomen 

 reaching to, but hardly exceeding the anal angle of the secondaries. 

 Legs stout, smoothly scaled, the ordinary spurs of middle and hind 

 tibite long, stout, unequal. Anterior femora in the male somewhat 

 enlarged basally and grooved interiorly, but not otherwise modified. 

 Primaries moderate, broad, rather abruptly widened at base, the outer 

 margin even, arched, only a little oblique, hence the ct)stal and inner 

 margins of nearly the same length. Venation normal. Secimdaries 

 proportionate. Venation normal, save that -3 and 4 are often on a stalk, 

 and vein 5 is distinctly weaker than the others. 



There is only a single species thus far described, and as based on this 

 the genus is readily distinguished from all others by the broad, obtuse 

 wings, which are suddenly widened at base and not trigonate, and by 

 tlie comparatively short palpi. Indeed, the genus on analysis shows 

 the deltoid characters somewhat obscurely.

Ground color a glistening smoky or bronze brown, varying to black- 

 ish. Head and thorax concolorous, abdomen paler, glistening gray. 

 Primaries almost evenly of the ground color to the subterminal line
