of which he does not know the Specific name, and that pupae forwarded 

 to him from Cahfornia by the same gentleman, were disclosed in Paris 

 in the following May. 



4— ALYPIA SACRAMENTI, (Pi. i, fig. 2). 



Alypia Sacramenti, Grote, Trans. Am. Ent. Soc, Vol. i, p. 327. 

 (Plate 6, fig. 38, ?.) (1868). 



Agdrisia Sdcramenti, Boisd., Ann. Soc. Ent. Belq. , Vol. 12, p. 69. 

 (1868-9). 



" ? . — Size, large. Black. Head, black; labial palpi well extended 

 beyond the point, black; inwardly touched with pale sulphur yel- 

 low scales. Antennae, long, black, thickened toward the apices. 

 Eyes, narrowly margined on the front, before the antennal insertion, 

 with pale sulphur yellow, and more prominently and continuously 

 so beneath. Legs, black, anterior and middle tibiae clothed with 

 orange colored hair. Thorax, black; the patagia and sides of the 

 prothorax are sulphur yellow, the former fringed with black hairs. 

 Abdomen, entirely black. 



"Wings, ample black. Primaries, with two sub-equal sulphur 

 yellow spots ; the first towards the base, irregularly sub-quadrate, iti! 

 upper margin being angulated ; the second over the nervules, sub- 

 ovate, oblique. Secondaries, with a single reduced sulphur yellow 

 spot shading to whitish, situate beyond the discal cell. Underneath, 

 the spots are paler, more irregularly shaped and notably larger; this 

 latter character is especially to be perceived when the single spot of the 

 secondaries is considered; it is here whitish and much larger, being 

 externally produced, than its analogue on the upper surface." 



Grote (loc. cit). 



Expanse of wings, ?. 1.30 inches. Length of body , ?. 0.55 inch. 



Habitat. — California. (Coll. H. Edwards and R. H. Stretch). 



The present species sustain a similar relation to A. dipsaci, with 

 that borne by A. Langtonii to A. Octomaculata. It is, however, larger 

 than any of the allied species. From A. Dipsaci, it differs prominently 

 by the single reduced spot of the secondaries; and from A. Grotei, 

 Boisd., (a species which I have not yet seen,) in having only two 

 instead of three spots on the primaries. 



I am indebted, for this fine species, to my friend, Mr. Henry 

 Edwards, of San Francisco, who took three specimens in July, 1870, 

 in the neighborhood of Donner Lake, at an altitude of 6,000 feet 

 above the sea, on the Sierra Nevada Mountains. Boisduval says
