Mr. Aiifi'iis writes me that there seem to be two varieties of I>. coutrac^a. 
One of them i.s a light chestmit-brown with the usual yellow lines, and the other is more the color of T). minisira; 
indeed, so )uuch so that 1 thought they might prove to be that species, hut the lines are precisely the same as the 
other variety in width and color. 
Habits. — Eggs, Aiigu&t 0; larvae, June, August, and September; adults, June, July, October, 
and November; localities, ^lissouri. District of Columbia, and New York. (Riley.) 
Food — Oak (Miss Morton and Mr. Angus); “Oak (Querctis), chestnut (Cos/uwm), hickory 
(Canja)-’’ (Beutenmiiller) ; oak and witch-hazel (Riley). 
Geographical distribution . — Massachusetts (Very, Mus. Comp. Zook); New York, New Jersey, 
Pennsylvania, Wisconsin, Illinois (French); West Farms, N. Y. (Angus); New York (Palm); 
Newburg, N. Y. (Miss Morton and Mrs. Fernald); Bnlfalo, N. Y., and Chicago, 111. (Bolter); 
Racine, Wis.; Chicago, HI. (Westcott); New York, southwestern Arkansas (Palm). 
Subfamily IV, — Ichthyurin^i*:, 
Head larger than in the Gluphisina^ but yet not so prominent as in the succeeding 
subfamilies; the front rather broad; clypeus (denuded) scutelhite; eyes hairy; antenme short, 
well ])ectinated to the tips; palpi large, long, ascending. Thorax usually with a dark median 
crest. Fore wings short and broad, ai^ex slightly upturned; outer edge a little bent; no 
subcostal cell, the first three subcostal venules turned abruptly up on the costa ; usually marked 
by four cross lines, two of them forming a large V. Hind wings with a rounded apex. Legs 
very densely scaled. Abdomen in 6 long aud slender, with a spreading dark tuft at the end. 
Fgg. — Hemispherical, with meridional ribs, on the surface ornamented with polygonal areas. 
Cocoon . — Thin aud irregular in sha])e; s])un between leaves. 
Larva . — Body rather long, slightly tlattencd, striped with yellow and dark, and somewhat 
hairy, usually with a pair of twin tubercles on first and eighth abdominal segments each. 
Freshly hatched larva with the hairs all tapering, at first without abdominal tubercles or hairs. 
Pupa . — Unusually thick, full and blunt at the end; cremaster ending in a S[)ine bearing two 
broad upeurved llattened hooks, each bearing four to five long setjc.

Moth . — Head not prominent, the front rather broader than usual, squarish; the clypeus 
(denuded) scutelhite in shape, raised in the middle and on the edges in front. Eyes hairy; 
anteiiiue short, as long as the thorax, thickly scaled above; branches long, slowly shortening 
towai'd the end, sparsely ciliated. In the ? tlie branches short, but distinct. ]Maxilhv distinct, 
'The use of this name by Kirby in place of Ichtbyura seems scarcely Jnstiliable, since in the Tentamen no 
description is given, aud in the A'^erzeiclmiss the name MelaIoph:c is the name of a stirps, under which are the groups 
or coitus Pygtvra and Ichihyura, the species under each being enumerated. Hiibner also does not in tbe Verzeiclinis 
fjpell tbo woTi\ Melainjyha, the singular of M(dalo])h{i‘ ; ho simply u.scs it to designate a group or coitus or genus 
(in the moileru sense). To resurrect and rehabilitate HdaJophw. under tbo name Mdalopha seems scarcely defensible 
or advisable.
