no adornment. The head, which is retractile, is seen in the extended position in 

 fig. Tc, just prior to the penultimate moult, and is small and rounded. 



Final instar (fig. I). Full green. Oblique bands on 9, 10, and 11 larger, pointed 

 at both ends and much pronounced ; in colour lemon, inclining to emerald, and out- 

 lined with warm sienna. Segments 5 and 7 are now adorned with small, and 6 and 8 

 with larger, circular patches of the same colours, situated above and in front of 

 the spiracles. Spkacles raw sienna. Small brown dots arranged in four transverse 

 rows mark the back of each segment. Head and segments 2 and 3 completely with- 

 drawn when at rest, and there is now no tail at all. 



Pupa. — Somewhat similar to that oi Pholus fasciatus.

General distribution. — Neotropical Region, except Jamaica and Leeward Islands, 

 northward to New England. 



A very common species in the larval condition among the vineyards of the seaboard. 

 Only occasionally noticed in the Interioi", where there is but little grape-vine grown. 

 The moth, occasionally found by day at rest on stems and walls, was seldom attracted 

 to light. The disturbed larva disgorges a bubbling green fluid, possibly as a means of 

 defence ; but, despite this, it sometimes, though more rarely, proves to be stung 

 by a dipterous parasite like its congener, F. fasciatus. 



Frass hexagonal and light brown, but sufficiently variable on occasion in length, 

 thickness, and colour as seemingly to denote the presence of an entirely diff'erent 

 species. The pellets are very apparent on the light grey dust of the vine-courses, 

 and the pupa, which may be some yards away, is often unearthed from its neat 

 subterranean cavity when weeding the ground. 



Ova. — Singly on leaves of grape-vines. 



Lakva. — First instar (fig. a). Somewhat similar to P. fasciatus. Ochreous to pale 

 white-green, with thin black tail held in a curved posture over the back, and almost 

 equal to the entire length. 



Second instar (fig, aa). Pale green, the dorsal area being enclosed by a couple of 

 white longitudinal bands. A small black spot is situated on the back of segment 12 

 in front of the tail, which is also black, curved over the back, terminated by a blunt 

 crimson lobe, and only proportionately shorter to the increased size of the cateipillar, 

 being now equal to rather more than half its entire length. 



Third instar (fig. h). The bright clear green of the fresh vine-leaf. In this stage 

 the form and design of the adult larva are assumed, except that segments 10 and 11 

 alone are adorned with unequal oblique white stripes directed headwards. The pair 

 on 11, both now and in the remaining instars, are always the most prominent and most
