Mr. Anuus writes me tliat there seem to be two varieties of I>. coiitracta. 



One c,r tbcm is a li.'ht rUestnut-brown with the usual yellow Hues. au,l (he other is uiore the color of I), mmistra; 

 in.leed. so much so that I thought they might iirove to be that species, but the lines are precisely the same as the 

 other variety iu wiilth and color. 



7/„/„7s._Eoos, Au-ust 9; larvae, June, August, and September: adults, June. July. October, 

 and November: localities, Missouri. District of Columbia, and New York. (Kiley.) 



Food plant.— Oix\i (Miss Morton and Mr. Angus) ; "Oak ((^ucrcm). chestnut ( Castania), hick.ay 

 (0«»-i/«)'' (Beuteiimiiller); oak and witcli-liazel (Riley). 



'Ocographiml (/(4/»-/iH/(V»«.— Massachusetts (Very, Mus. Comp. Zool.); New York. New Jersey, 

 Pennsylvania, Wisconsin, Illinois (French); West Farms, N. Y. (Angus),- New York (Palm); 

 Newburg, N. Y. (Miss Morton and Mrs. Fernald): Buffalo, N. Y., and Chicago, 111. (Bolter); 

 liacine. Wis.; Chicago, 111. (Westcott); New York, southwestern Arkansas (Palm). 



Subfamily IV.— Ichthyubix.e. 



Head larger than in the Ghqihi.sina', but yet not so i>romineut as iu the succeeding 

 subl'amilies; the front rather broad; clypeus (denuded) scutellate; eyes hairy; antennae .short, 

 well pectinated to the tips; palpi large, long, ascending. Thorax usually with a dark median 

 crest. Fore wings short and broad, apex slightly upturned: outer edge a little bent; no 

 subcostal cell, the first three subcostal veiuiles turned abruptly up on the costa; usually marked 

 by four cross lines, two of them forming a large V. Hind wings with a rounde.l apex. Legs 

 very densely scaled. Abdomen in $ long and slender, with a spreading dark tuft at the end. 

 " ^^/^/.—ilemispherical, with meridional ribs, ou the surface ornamented with polygonal areas. 



OocooH.— Thin and irregular in shai)e: spun between leaves. 



i«riY(.— Body rather long, sliglitly tlattened, striped with yellow and dark, and somewhat 

 hairy, usually with a pair of twin tubercles ou first and eighth abdominal segments each. 

 Presh'ly hatched larva with the hairs all tapering, at first without abdominal tubercles or hairs. 



i'i(j„(._Unusually thick, full and blunt at the end: crenuister ending in a si>ine bearing two 

 l)road upcurved flattened hooks, each bearing four to five long setae.

Moth.—U&m\ not prominent, the front rather broader than usual, squarish: the clypeus 

 (d-^nuded) scutellate in shape, raised in the middle and on the edges in front. Eyes hairy; 

 antenna- short, as long as the'thorax, thickly scaled above: branches long, slowly shortening 

 toward the end, sparsely ciliated. In the S the branches short, but distinct. .Alaxilhv distinct, 



' The use of this name bv Kirbv iu place of Ichthyura seems scarcely justiaable, since in the Teutamen no 

 description is given, and in theVerzeichniss the name Melalopha^ is the name of a stirps, under which are the groups 

 or coitus 7'./y-ir(( and Irhlhijiira, t\w species under each being enumerated. Hiihuer also does not in the Yerzeichnis 

 spell the word M.'lalupha.'the singular of Melaloiiha-; he simjily uses it to designate a group or coitus or genus 

 (in the moderu seuse). To resurrect aud rehabilitate ilelalojthir under the name Mdalophu seems scarcely defensible 

 or advisable.
