234 JOHN B. SMITH. 



in the soinewliMt larger size, did uot differ from Incina ; in fact, ex- 

 cept for its uiiiforinly larger size, this resembles the British-American 

 form more closely than it does the one found with it. The example 

 from Senator, Arizona, is a fen}ale, with the s. t. space only a little 

 paler, and a mere trace of reddish opposite the anal angle. This 

 form covering the same range as the preceding can scarcely be con- 

 sidered a race; it may, as already suggested, be the first brood of 

 altua, better nourished than the other; but if that is the case, the 

 broods lap seriously, one example being dated August 24-30, while 

 one female altua from the same locality is dated July 16-21. This 

 particular form may be known as megarena. 



The fifth series is composed of five male and seven female exam- 

 ples from Sierra Nevada, California, which came originally from 

 Mr. Henry Edwards. With the same type of maculation as in 

 megarena the contrasts are much greater, and the red shade in the 

 basal and s. t. space is much more pronounced. But there is no doubt 

 as to the standing of this form, because the male genitalia are very 

 markedly and obviously different from any other, resembling much 

 more nearly quadrilineata than olivacea. This is a good species, and 

 I have applied to it the name davena. 



The sixth series is composed of five females from Livingston, 

 Vancouver (vii, 17j; Corfield, Vancouver; Corvallis, Oregon (vii, 

 19, 21 and viii, 3). These have a darker, richer color than any of 

 the preceding; the lines are more irregular, and there is a mossy 

 green shading in both the basal and s. t. spaces. This brings the 

 series nearer to typical olivacea than any other of the intermediate 

 forms; but here again the reniform is large and irregular, tending 

 to become discolored. It is unfortunate that I have no good males ; 

 but I have no serious doubt that we have to do with a good species 

 which I call ohnigra. There is a single male from Nanaimo, Van- 

 couver, that I haV'C associated with the females, but it is so badly 

 rubbed that little can be made of it, save that it is very like davena 

 and even more brightly marked. The genitalia of this specimen 

 tell nothing and are very like tyical olivacea. The example is cer- 

 tainly none of the other species from this region. 



The seventh series is composed of one male from Seattle, Wash- 

 ington, and three females from Corfield, Vancouver. The male ex- 

 pands 28 mm., the fetnales 24 and 25 mm. This raises the question 

 whether the specimens are correctly associated ; but I believe they 

 are, and that more material from Washington will lessen the dispro 

 portion. The species again becomes olivaceous, and the mossy green 

 in the male extends throughout the wins:. In the female a reddish
