" ? . — Resembles Alypia octomaculata. Black. Head, black; labial 

 palpi well extended beyond the front, black, roughly scaled; eyes very 

 narrowly margined with pale sulphur yellow scales before the antennal 

 insertions, and more prominently and continuously so beneath. 

 Patagia, pale sulphur yellow, fringed with black hairs. Abdomen, 

 entirely black, or blackish. Legs, black; anterior and middle tibise 

 clothed with orange colored scales; on the anterior tibige the scales are 

 thicker and more prominent, and do not extend over the lower 

 extremity of the joint ; on the middle tibice the orange scales are 

 shorter, forming a lateral tuft, and include a black dot near the lower 

 extremity of the joint ; the middle femora are faintly shaded with 

 orange inwardly. All the tarsi are marked with whitish, the basal 

 joints most distinctly. Antennae, long, gradually thickening toward 

 the tips, black, narrowly sub-annulate with white over their slender 

 basal portion.'' 



"Wings, black, with a faint reflection. Primaries, with two large 

 sulphur yellow spots ; the first towards the base, smaller, sub-triangu- 

 late ; the second over the nervules, larger, sub-pyriform, oblique. 

 Secondaries, with a reduced, basal, sulphur yellow spot, and an outer, 

 much larger sub-quadrate patch. Beneath, the markings of the 

 upper surface are exactly repeated, while the yellow of the spots is 

 paler. The fringes of both wings, on either surface, are entirely black 

 and silky."

This species is readily distinguishable from A, octomaculata by its 

 smaller size, and the different color and proportion of the spots on the 

 secondaries. The specimen in my collection was taken by Mr. Lor- 

 quin, who furnished Boisduval with the specimens from which his 

 description and that of Grote, quoted above, were drawn. The exact 

 locality in which they were taken has not been preserved, though it 

 was probably in the foot-hills of the Sierra Nevadas. Dr. Boisduval 

 states that Mr. Lorquin has raised the larvae on a species of Dipsacus
