Genus Leucophobetron, nov. 
There are two species which differ from Calybia in the much larger 
size (25 to 35 mm.) and the divergent tufts at the tip of the abdomen 
in the male, both described as Liparidse. Dewitz has shown (N. Act. 
K. Leop. Deut. Akad. Nat. xliv, 252) that one of them is a Eucleid and 
it is probable that the other is also. The first is L. argentiflua * Geyer 
(Samml. Exot. Schmett, iii, pi. 18, 1836), from Cuba; the second is 
Z. argyrorrhcea Hiibn. (Zutrage Exot. Schmett., ii, Figs. 245, 246, 
1823). For convenience I would separate them from Euproctis and 
Eupoeya under the above term.

Special Structural Characters. 
Outline elliptical, more narrowly so if the appendages are excluded ; 
dorsal space broad, even, flat; lateral space broad, sloping, rounded; 
subventral space rather broad, continuous with the lateral space, not re¬ 
tracted. Ridges practically absent, the subdorsal indicated by the 
change in slope between back and sides. Tubercles greatly modified, 
as in Phobetron. In stage I a subdorsal row of single spines with en¬ 
larged bases, two on joints 3 and 13; lateral spines obsolete, repre¬ 
sented by obscure papillae; subventral setae large and distinct. Ulti¬ 
mately the subdorsal warts are attached narrowly, but with very broad 
bases, encroaching on the dorsal and lateral spaces and produced later- 
* Mr. W. F. Kirby has very kindly examined Hiibner’s works for this species 
and has sent me the above correction to the reference in his catalogue.
