AMERICAN LEPIDOPTERA. 25 



This is the species that I had erroDeously identitied as contenta 

 Grote from a faded example, the real species being afterward rede- 

 scribed by me as j^omona.

 Ground color a dirty bluish fjray, with a slight admixture of red. Head a little 

 darkest between the antennse ; collar inferiorly with reddish tinge, a black line 

 just above the centre, emphasized by a surmounting series of whitish scales. The 

 thoracic crest is not prominent and not divided. The primaries are irregularly 

 mottled with smoky brown and none of the marking are distinct. The t. p. line 

 is geminate, tlie defining lines black, the very narrow included space a little palei 

 gray. It is very strongly zigzagged, forming long teeth in the interspaces. The 

 t. p. line is not sufficiently evident to be described in either of the specimens be- 

 fore me. The s. t. line is broken and consists of a series of sagittate black spots, 

 which are outwardly marked by reddish or whitish scales. Just below the apex 

 is a dusky terminal shade that emphasizes the line at that point. There is a 

 series of blackish terminal marks on the veins and an appearance of pale termi- 

 nal lunules. The ordinary spots are vaguely traceable. The orbicular is a little 

 paler than the ground color, without defining line, but with four black dots 

 arranged almost in a square. The reniform is large, a little dilated inferiorly, 

 yellowish brown centered, and the lower margin marked with blackish scales. 

 Secondaries silky, reddish gray, with a discal lunule. Beneath with reddish 

 tinge, powdery, somewhat smoky gray, both wings with an outer line and a dis- 

 cal spot. 



Expands 35-42 mm. = 1.40-1.68 inches. 



Hab. — Alameda County, California, July, larva on apple ; Central 

 California; Olympia, Washington ; Northwest British Columbia. 



One male and three females, two of the latter in excellent condi- 

 tion, are now before me. The species is readily recognizable by the 

 blackish dots emphasizing the ordinary spots, the lower margin of 

 the reniform being even somewhat prominent in one specimen. The 

 male antennae are lengthily ciliated, the joints a little marked. 



This is the species described by me as poviona. I had named 

 what I supposed was a faded example of contenta by comparison 

 with the type in the Edwards collection, and afterward received 

 under the same name fresh examples of the identical species, else- 

 where in this essay named amanda. Hence, when I received good 

 examples of the real contenta I did not recognize it. There are f\)ur 

 examples in the Edwards collection.
