206 W. IT. Edward's Descriptions of Diurnal Lepidoptera. 



1865. What surprised me was, that not one of the latter, either % or 

 9 , was seen by me that season. Nor did I see a $ of Nefflecta, al- 

 though the males were to be seen everywhere along the roads, where 

 there was a moist spot for them to gather on. The £ of pseud argiolus 

 I took in 1865, on the flowers of the rattle weed, as stated above, and 

 they were more numerous, if anything, than the males. But, although in 

 1866 I watched these flowers carefully, not a neglecta of either sex was 

 seen about them. Where the 9 was to be found I did not discover. 



Every out-door collector knows that this disappearance or replacing 

 of one species by another, is not unusual. 



Lycvena Mertila, nov. sp. 



Female. Expands 1 T \ inch. Primaries long and narrow ; both 

 wins;s brown, with slate-colored hairs at base and alona; inner margin 

 of primaries. 



Under side clear cineraceous ; bluish at base; primaries have a sin- 

 gle transverse sinuous row of round black spots, each circled with 

 white, as also in the luuule in the arc; from the arc a whitish ray runs 

 toward the base. 



Secondaries have a row of eight small black spots in points, each 

 circled with white; of these, two are on central margin, four nearly 

 parallel with the hind margin ; the seventh below the others and ge- 

 minate; the eighth minute, nearly concealed in the marginal hairs; be- 

 tween the 2nd and 3rd and the 6th and 7th the spaces are wide ; on 

 the arc a streak, and midway between this and the base a black point; 

 on the costa above this one slightly larger, all circled with white. 



From California. 



The male of this distinct species I have not seen. 



Syrichtus alba, nov. sp. 



Male. Expands 1 T 5 inch. Upper side of both wings white, the bases 

 and basal half of the abdominal margin of secondaries bluish-grey; hind 

 margins edged with a dark line, on which rests a series of blackish serrat- 

 ed spots, the two next the apex of primaries small and double, the 3rd 

 and 4th smaller than the 2nd, with a few dark scales preceding; the 

 5th double; the ends of all the nervules black; the four apical ner- 

 vules black at their insertion, making a conspicuous triangular spot, 

 the inner of the four nervules projecting a spur half way to the hind 

 maruin, under the end of which spur are a few black scales indicating 

 an obsolete rounded spot; fringe white, but on primaries with a dark 

 line running through it. 



Under side white; an indistinct soiled patch at apex of primaries;
