(iii, iv, and v), the most posterior one smaller than the others; 
subventral wart with two setae. 
This curious little larva has lost its warts by degeneration in 
adaptation to its habits of sitting exposed on lichen covered rocks, 
since a hairy larva would be conspicuous in such a location. 
But it retains the Euchromian characters. 
Amata phegea, Linn. 1 
Abdominal warts large, except iv which is small; densely haired, 
the hairs spinulose. On thorax a large elongate wart followed by 
a small but distinct one (iib). Stigmatal wart large with a small 
wart behind it (iii), smaller than iib. Subventral wart large. 
Ctenucha virginica, Charp. 
Much as in the preceding; the warts rather smaller, though iv 
less so in proportion. On the thorax iib and iii are reduced to 
insignificant rudiments with a single seta or none, and there is a 
single elongate wart above the stigmatal wart. 
Syntomeida ipomoeae, Harris. 
As above. The single elongate subdorsal wart on joints 3 and 4 
bears a long black hair pencil to correspond with one at the 
posterior end of the body. Other hair dense and even, resembling 
that of a Halisidota. The specimen before me is in alcohol and 
shrunken, so that I cannot detect the rudiments of iib and iii on the 
thorax if such be present. 
Syntomeida epilais, Walker. 
The warts are small and compact, and the soft hairs arise from 
them in slender pencils, not divergent as usual. On the abdomen 
iv and v are reduced to tiny dots; on the thorax a small obscure 
seta represents iii, the distinct warts being normal, the single 
subdorsal wart small, not elongate. 
Scepsis edwardsii, Grote. 
In stage I, the origin of the single subdorsal wart from ia, ib, and 
iia may be distinctly seen, iib being remote and weak. The setae 
differ from the degenerate Lycomorplia only in being strictly single 
and lacking the subprimaries. 
In the mature larva I see no trace of the two rudiments iib and 
1 This is the type of Zygaena and Syntomis according to Kirby. Zygaena is preoccupied 
and Amata Fab. antedates Syntomis, which is therefore a synonym. The type of Amata 
may betaken as passalis Fab. from India. It is congeneric with phegea according to 
Hampson.
