44 JOHN B. SMITH. 



Ground color yellowish red, powdered with rusty brown. Head and thorax 

 shaded with purplish, a white tuft at the base of the. antenme, tip of the collar 

 pale. There is a white spot at the middle of the extreme base of the wing. 

 Basal line geminate, extending to the middle of the wing and within it the base 

 is of the palest ground color. Beyond this line the basal space above the sub- 

 median vein is filled with purplish, and this sometimes extends through the cell, 

 forming a dark cloud, which is quite prominent in some specimens. T. a. line 

 geminate, inwardly oblique, rather difficult to trace in most examples, except 

 below the submedian vein, where it is strongly outcurved. T. p. line geminate, 

 outcurved over the cell and almost evenly oblique below that point. S. t. line 

 irregular, outwardly dentate on the veins, the lower rusty brown. The s. t. 

 space is contrastingly purplish, and this shading may extend so as to darken the 

 terminal space, except at the apex. The fringes are also purplish. The median 

 shade line is narrow, not very obvious in most cases above the reniform. obliquely 

 inward to about the middle of the inner margin. The ordinary spots are distinct ; 

 the orbicular moderate in size or rather large, with a tendency to become trian- 

 gular in shape, sometimes with a dusky central dot. The reniform is moderate 

 in size or rather small, almost even, the white margining spots rather narrow, so 

 that as a whole the spot is not so strongly contrasting as in some other cases. 

 The claviform is double, the upper spot as a rule hardly half the size of the lower, 

 the latter varying from round to oval, the oval being the more usual form. 

 Beneath yellowish, powdered with purplish, with a discal lunule and a more or 

 less obvious outer line on both wings. Expanse 1.28-1.68 in. ; 32-42 mm. 



Hab.— From Canada to Virginia, west to Colorado; Maine; 

 Massachusetts; New York in September ; Central Illinois, August 

 29th ; Champaign, 111 , August 3rd. 



This is one of the most common forms belonging to this series 

 and is represented in most collections. It is powdery, and the con- 

 trasting s. t. space is easily recognizable in good examples. The 

 reniform is not strongly contrasting, the white spots being narrow 

 and the central portion or lunule being itself not very large. There 

 is nothing to be added to what has been already said of the sexual 

 characters, which are of the usual type. In the figures 33 shows 

 the parts flattened out on the slide and distorted by crushing. It is 

 a camera lucida sketch like all the others and illustrates the im- 

 portance of seeing rightly. 



Hydrcecia appasioiiata Harv.

This species is perhaps best described by comparison with rutila, with which it 

 is generally confused in collections. It is indeed, on close examination, more 

 like limpida, but much redder in general tint. The main characteristic in this 

 species is the very large reniform. the inferior portion of which is much larger 

 than the upper, and this constitutes the most striking feature. The primaries 

 are also much more prominently shaded with purplish, this shading extending 

 through the median and filling almost the entire terminal space. In other 

 respects and in general type of marking the resemblance to rutila is evident. 

 Expanse 1.20-1.50 in.; 32-37 mm.
