and polished; body cylindrical and uniform, tapering a little posteriorly; seg- 

 mental divisions fairly defined, and a tuft of several short hairs springs from 

 each of the indistinct tubercles. In colour there are two extreme varieties, and 

 the larva varies between these forms. Var. 1 has the ground colour a delicate 

 pale green strongly tinged indeed with yellow ; head pale yellowish-green, the 

 mandibles and ocelli brown ; medio-dorsal stripe dark green or purple in different 

 specimens ; sub-dorsal stripes yellow, and there are two other fine but very faint 

 yellow lines, one above and the other below the spiracles: segmental divisions 

 also yellow ; spiracles black, very narrowly encircled with white. Ventral sur- 

 face, legs and prolegs uniformly pale yellowish-green. 



"Var. 2 has the ground-colour brownish-yellow ; head also brownish-yel- 

 low, freckled with brown ; medio dorsal stripe broad bright purple ; sub-dorsal 

 stripes also broad, but of a much less distinct dull pale purple, and having a 

 fine white line running through them; a narrow purple line, edged above with 

 white, extends along the spiracular region. Ventral surface, legs and prolegs 

 uniformly pale yellowish-brown. Feeds on the flowers of Erythraea centaurea. 



"The pupa is slender, and nearly (if not quite) as long as the full-grown 

 larva; it is of almost uniform width, the last two segments only tapering to the 

 anal point. It is glossy and cylindrical, but there is a depression on the thorax 

 and front abdominal segments; the snout and top of the thorax are promin- 

 ently and sharply defined ; the leg-cases extend a long distance down the front 

 of the abdomen, but before the end, become detached from it. The ground- 

 colour is yellow, but is almost hid with a deep pink, which is sufTused all over 

 the surface, and almost forms a stripe from the head through the abdominal 

 segments ; wing- and leg-cases dingy olive, tinged with pink." 



It is interesting to note that one of our specimens bears the label 

 "on Erythraea venusta."

Gray brown. Antennae dotted above. Eye surmounted by a white line. 

 Palpi moderate, whitish above. Abdomen with paired dorsal dots in the distal 

 half. Legs white on one side, the hind pair brownish, dark brown on the other. 



Primaries dull brownish or grayish brown, ochreous toward base and 

 inner margin, marked as in the preceding species but with a pale longitudinal 

 dash in the first lobe. Fringes gray brown with paler bases and a mixture of 

 whiti.sh hairs which predominate in the type on the outer margin of the first 

 lobe. Fringes of outer margin with three tufts of black scales on first lobe 

 and two on second in type, damaged in other specimen. Secondaries brownish 

 with coucolorous fringes, their bases pale as in scmicoslata. The anal angle 

 of the first lobe of the primaries is more evident than in scmicostiitii, and the 

 outer margin therefore more concave. Expanse 16.5-18 mm.
