Head greeuish olive above, whitish beineath ; labial palpi whitish, with green 

 tinge. Eyes and tongue brownish black. Antennaj black above, reddish be- 

 neath, terminal spinule white, with the extreme hook yellowish brown. Thorax 

 above greenish olive, whiter at the sides and beneath. Abdomen greeuish olive 

 with a white tinge, except the three anal and the fifth segments, which are dark 

 olive green, the anal segment being marked in the centre with a paler streak. 

 Beneath, the abdomen is greenish olive, with the segments edged posteriorly 

 with white. Anterior win^s rich greenish olive, paler at their base, except to- 

 wards the costa, w^here there is a darker shade. The median space rich greenish 

 olive, narrowing to the internal margin, and enclosing a black discal streak. 

 Behind this band, and resting on the internal margin, is a pinkish shade, not 

 visible in old specimens, and beyond this is a rich olivaceous band, spreading to 

 and widening out upon the costa, the outer edge being somewhat notolied. 

 Fringe of the anterior wings olive green tipped with black. Posterior wings 

 bright orange yellow, with a broad and moderately regular black marginal band. 

 Fringe yellowish white. Underside of wings wholly olivaceous green, darkest 

 at the base. Across the disc of the secondaries is a slightly waved whitish band. 

 The discal streak of the primaries is scarcely visible. Feet and legs whitish 

 green. Expands 1.25 — 1.50 inches ; 31 — 37 mm. 



Hab. — Northern California, Iowa, Oregon. 



Perhaps the most common species of the genus. ^Ir. Edwards 

 says " not rare in May and June. It appears to delight in the 

 flowers of the various species of Gilia." 



Mr. Butler makes this species the type of his genus Dieneees, Ann. 

 and Mag. N. H. 1881, ]>. 308, which he characterizes as follows: 

 "Allied to Cinogon, but the margins of the wings not sinuated, the 

 secondaries smaller, shorter ; the anal tuft better developed, expanded 

 in the male ; coloration of Pterogon." 



The characters are scarcely strong enough to warrant the genus in 

 this group. Its recognition would necessitate a distinct genus for 

 ever}' species here referred to Lepisesia — an extent to which I am not 

 yet ready to go. 



Dr. Boisduval says his specimen was raised from the larva by Mr. 

 Lorquin, but he gives no description of it. Of this species I was 

 able to examine the genitalia. They are of the ordinary Sphingid 

 type, the plate somewhat flattened transversely, the superior hook 

 short, stout, obtuse, the lower similar, but much shorter. The side 

 piece is oblong with a rounded tip. So far as I could make out there 

 was no distinct clasper, but this needs verification, as I had but a 

 single available male.
