with gray. Outer margin crenulate, apex of first dots acute, produced. Fringes 

 grayish witli paler bases, including tufts of dark scales on inner margin and 

 a basal row on outer, sometimes cut with white. Secondaries as in punctidac- 

 tyla. Expanse 18-22 mm. 



Male genitalia as in punctidaclyla (see plate L, fig. 13), with the 

 uncus slightly more slender. 



Distributions: Europe. We have ten specimens from Carmel, 

 Cal., taken in April and two from the San Bernardino Mts., Cal., taken 

 in June and July. The species is in the Fernald collection labelled 

 West Farms, N. Y. 



The early stages have been studied in Europe, and the following 

 description of the larva is given by Porritt. — After noting that the 

 larva is very like that of punctidactyla he writes : "As in that species 

 there are two distinct forms, and intermediate varieties occur partaking 

 more or less of each of these extreme forms : — 



"Var. 1 has the ground color deep purple; head yellowish-grey, or yel- 

 lowish-brown, marked on the crown and sides with black, the mandibles brown ; 

 medio-dorsa! stripe smoke-coloured ; sub-dorsal lines, and another line of equal 

 width below it, white, but interrupted and not very conspicuous; and below 

 these is another scarcely so pale line along the spiracles ; hairs and the distinct 

 tubercles white. Ventral surface and prolegs greenish-olive, anterior-legs shin- 

 ing black, ringed with paler. 



"Var. II has the ground color bright pale green; head as in Var. I; the 

 pulsating dark smoky vessel — in some specimens tinged with pink anteriorly — 

 forms the dorsal stripe: sub-dorsal lines indistinct, whitish; below these is 

 another line, but much interrupted and broken into short lengths ; there are 

 no lines along the spiracular region ; hairs and tubercles white. Ventral sur- 

 face and prolegs of the bright green of the dorsal area, the legs shining black, 

 ringed with white." 



Tutt vv'rites briefly of the pupa as follows : 



"The pupa appears to vary in ground colour to the same extent as the 

 larvae, the ground colour varying from pale green to dark purple, but getting 

 darker in the paler forms just before emergence. In this species, as in the 

 next, [punctidactyla] the antennae cases are quite detached, and these, with 

 the two curious curved protuberances specially characteristic of this genus 

 [AmhlyptUia], give it a very strange and curious appearance." 



Tutt and Hofmann, in summarizing the biological knowledge of 

 the species, both mention Stachys, Ononis, Geranium and Pelargonium 

 as food-plants, and Hofmann adds Salvia, Euphrasia, Bartsia, Mentha 

 and a few others. It is mentioned as feeding on the buds of most of 

 tliese, and in one case on leaves.
