Larva. — Mr. Belfrage, who has reared llic moth from the caterpillar 



(figured on of the plates), ami 'has sent me specimens alive, tells me thai 



ii feeds mi Zygadenm nuttallii Gray (kindly identified by Mr. S. Watson). 

 He says: "The larva is flesh-colored, with dark spots, and feeds on the 

 flowers. Il is gregarious, and appears during the flowering of the plant, viz, 

 late in April and beginning of May, at the end of which time it transforms to 

 a reddish-brown pupa, which is not hatched before the next year, aboul the 

 time when the plant commences to flower, or shortly before. It is not rare.'' 



In living specimens received from Mr. Belfrage, the body is very broad, 

 thick, somewhat flattened; the ground-color yellowish-orange, including the 

 head, which is immaculate. There is a dorsal and two lateral rows of large, 

 conspicuous, black blotches, the lower lateral row not seen from above. 

 Beneath is a row of small median black dots. 



Length, 0.60 inch.

6 <* , 6 2 . — Head and body cinereous; anterior edge of front with blackish 

 scales along the orbits. Palpi rather long, scarcely so large as in E. alisynthiata, 

 whitish above, dark on the sides. Antennas finely ciliated beneath, above 

 minutely annulated with black. Thorax cinereous, uniformly concolorous 

 with the wings ; a transverse black band in front, ending on the patagia. Fore 

 wings uniformly cinereous, with indistinct lines or bands; on the outer third, 

 beyond the discal spot, russet-brown between the veinlets. Veinlets dotted 

 with black scales; on the costa, three dark, indistinct spots within and two 

 beyond the discal spot, the two outer ones being the largest, and sending faint 

 lines across the wings, all bent outward at right angles below the costa. 

 Discal dot large, distinct, black; beyond is a broad transverse area, where 

 the veinlets are dotted more thickly with black scales than elsewhere; 

 bounded beyond by a wavy, doubled, elbowed line, extending from costa to 

 median vein ; between the angle and the costa the line is bent inward on the 

 subcostal vein; submarginal whitish line very narrow, more zigzag and linear 

 than usual, often interrupted, consisting of intervenular dots, edged externally 

 with dark scales. A geminate white dot on internal angle, very distinct, form 

 ing a V, with the lower dot much smaller than the upper. Fringe long, cine- 

 reous, interrupted with dusky on the end of the veinlets. Hind wings with
