1910] Coolidge — Notes on Leptarctia california 167 
Catalogue Lepidoptera Heterochroa, Nemophila california, which, 
as Stretch showed in his addenda and corrigenda (p. 240), is the 
same as lena Boisd., of which adnata Boisd. was a synonym, and 
as it has priority, lena must itself drop into synomical rank. Pack- 
ard, Synopsis of the Bombycide of the United States, 1864, does not 
record any of the forms of Leptarctia. Stretch, under L. lena, 
wrote, “I strongly suspect that Pltaarctia modesta, Packard, is one 
of the many varieties of this species, although a specimen forwarded 
to Doctor Packard was returned with this query, ‘What is it?’ That 
it is congeneric is, I think, beyond doubt, as the peculiar thoracic 
markings are minutely given in the diagnosis of P. modesta.” 
Pltaarctia modesta has, however, turned out to be only a form of 
Parasemia plantaginis Linn., another very confusing and variable 
species. In 1882 Grote (New Check List of North American 
Moths) gives decia, lena and dimidiata specific rank, with califor- 
nie as a synonym of lena. This arrangement concurs with that of 
the list of the Brooklyn Entomological Society (1881), except that 
there is no mention of californie in the Brooklyn list. In 1881 
Butler (Ann. Mag. Nat. Hist., Vol. VIII.) describes four more 
varieties, namely: Stretchii, Boisduvalii, latifasciata and fulvofas- 
ciata, his descriptions being based on the specimens figured by 
Stretch. He also retains as valid, the four names already proposed. 
In 1889 Prof. G. H. French published in the Canadian Entomologist, 
Vol. XXI., a paper on the “Preparatory Stages of Leptarctia cali- 
fornie Walker, with Notes on the Genus.” In this paper all of 
these eight names are retained and in addition three new varieties 
are described. His arrangement may be summarized as follows: 
Leptarctia californiae Walker. 
stretchii Butler. 
boisduvalii Butler. 
dimidiata Stretch.
