% 9 • Compared with G. aequinoctialis, which the present species 

 closely resembles, G. vermiculata is slenderer, smaller, and the abdo- 

 men and hind wini;s are less brilliantly cyaneous. The stigmatal abdo- 

 minal white scales form continuous lateral white lines, and are not re- 

 stricted to segmentary dots, as in G. aequinoctialis. The upper portion 

 of the median white patch is more extended and nearly covers the dis- 

 cal cell, whereas in G. aequinoctialis it is restricted to a subquadrate 

 spot at the outer extremity of the cell. On the secondaries the medi- 

 an patch is separated into two portions in G. ae(juinoctialis, by the in- 

 trusion of the dark scales which form the ground color of the wing. A 

 A'ery numerous series of G. vermiculata, has been brought by Mr. 

 Ridings from Colorado Territory, the examination of which has evi- 

 denced the fact of the constancy of the species. 



The three species of Gnophaela here cited, are structurally identical 

 and very interesting, from the constancy to the very evident and simple 

 generic pattern of ornamentation ; their mimetic relation to the Diurnal 

 Sfalaclttis heliconides, has been already noted by Mr, Grote (1. c), A 

 specimen of G. vermiculata has been deposited in the Berlin Museum, 

 The description of Gnophaela, Wa//,-.. in the British Museum Lists. 

 is unibrtunately so insufficient as to have prevented the recognition of 

 its characters by Mr. Grote when describing the species from Colorado 

 Territory. 



3. Gnophaela HopfFeri, n. sp. 



S 9 • '^'ze large. Head black ; labial palpi black, except at base, 

 wliere they are powdered with orange-yellow scales. Sides of the pru- 

 thorax orange-yeilow, which color extends between the anterior legs at 

 base. Legs, black, slightly touched with white; the minute spurs on 

 middle and hind tibiae are whit.;. Thoracic region, above and beneath, 

 black. Abdomen, cyaneous black; a white, lateral, stigmatal line, as 

 in G. vermiculatu. Wings large and full. Primaries trigonate, brown- 

 ish-black, with tlrrc(! dull lemon-yellow spots at the middle divided by 

 the median nervure and its fourth nervule; between this latter at base 

 and the continuation of the nervure, the outer and smallest is placed. 

 The upper spot, at the outer extremity of the discal cell, is restricted 

 as in G. aequinoctiali.s. Over the nervules, terminally, is an oblique 

 series of four interspaceal, uneciual, ovate yellow spots, of which the 

 second and lai-gest is placed opposite the discal cell; these spots are
