414 ON SPECIES OF HADENA SMITH. 



spots, of which the reuiforin is usually more "or less filled with black. 

 There is no coaaecting shade between the median lines. 



Illata, or as it is more commonly known, sufusca, is of a pale violet 

 gray, with ii reddish suffusion, which becomes darker and more intense 

 toward costa. The maculation is obsoletely indicated, and the species 

 easily recognizable. The tip of harpe is of the usual form, the spinu- 

 lation along inner margin sparse. Theclasper is much reduced in size, 

 is cylindric and rather acutely terminated, and arises from the margin 

 .of the harpe just back of tip. 



Vultuosa is more yellowish or reddish luteous, with the maculation 

 more distinct, and with a black basal streak which separates it at 

 once from the preceding. The harpe and tip of S are as in suffusca, 

 but the clasper does not arise from the margin, is stronger and some- 

 what curved. 



Apamiformis is marked like vultuosa, but differs at once by the deeper, 

 more chocolate-brown color. The genitalia are peculiar. The tip is much 

 like that of the preceding species in shape, but the superior angle is 

 very broadly rounded and excavated, and the greater part of the inner 

 face of tip is rather densely clothed with coarse spinules. The clasper 

 is very short, thick, straight, and obtuse, very different from the long 

 slender form peculiar to most species of the genus. 



In synoptic form the differences are as follows:
