Moth, — “P]xpause of Avings, 31 mni.; leiigtli of body, 10 iiim. 
“The ground color of the anterior wings gray, s]>rinkled Avith black atoms and ATith white and 
faint browiiisli and ocdierous stains^ the half line and the interior line absent; the orbicular spot 
present as a geminate, blackish, u])right, lunate mark, prece<led by a Avhite stain; the reniform a 
similar but simple and more distinct mark surrounded by a faint ocherou.s annulus; the median 
shade passes between the spots; it is thickened below the reniform, forming a black .simt, but is 
afterward lost; the exterior line is only present in the central part of the wings; it is geminate, 
dentate, and Ibrms a particula^rly proniiiient indentation opposite the reniform sjmt; a contrasting 
apical white shade, below Avhich aiipears a dilfuse bhndcish shade clearly cut above, and the black 
distiiict subterminal Hue formed of oblique mark.s between the ner\'ules; fringes long. 
“Posterior wings uniform dark fuscous, with lighter fringes. Beneath, gray, Avith numerous 
black atoms; the lines and discal dots are obsolete.’' (■Morrison). 
“Habitat, Waco, Tex., ^March 0;’’ Texas (French). 
Morrison’s type is in the museum at Cambridge, IMass. 
Note. — Edema prodncta Walk., Cat. Lep. Het. Br. Mus., v, p. 1031, 1885, and Edema fiiseescens 
Walk., loc. cit., p. 1031, are species of Ingura, a genus of Noctuidie, according to Crote and Robin- 
son. Edema f phujiata Walk., Cat. Lep. Het. Br. 5Ius., xxxii, p. 427, 1805, “belongs to Farorgyia 
Pack.” (Grote and Robinson, Trans. Amer. Ent. Soc., dulj', 1808). 
Subfamily VI.— IlETEROCAmuNiE. 
Moth. — The head is tufted on the A^ertex, so as to liave a triangular-shaped hollow on top of 
the head. The male antennic are liliform in their distal fourth. Fore Avings usually long and 
narroAv (in lij’parpax, broad -and short), Avith the outer edge A^ery oblique, rather more so than 
usual; a subcostal cell usually present, and long and narrow. 
L^n*rn.— Compressed or round, and, as the name (d‘ the typical genus suggests, A’arying 
greatly in shape, markings, and coloration; either noctuiform, Avith moderately long legs, becoming 
in lleieroeampa luuvolor A'ery h)ng, and in Macrurocampa forming true stenia])oda like those of the 
Ceruriiue; body either smooth or armed Avith high nutant tubercles oii first, lifth, and eighth, or 
first and eighth, abdominal segments. Larvie in stage I often Avith large antlers. 
Larva*, usually spinning a slight, thin cocoon. 
Pupa . — Stout, full, Avith the spine of the cremaster well deA^eloped. 
SYNOPSIS 01’ TIIK GKNEUA. 
A. Antennaj of ^ almost or quite plumose nearly to the tip; palpi and legs long and slender; fore wings 
hroad and short; body and wiugs pink. Larva like that of Schizura, with a doul)le lunnp on iirst and 
eighth abdominal segments Iltfparpax 
Like llyparpax, hot fore wiugs longer and narrower and imuo acute at apex; tip of i iiutc*nu:n more 
filameutal fCuhtiparpax 
Like Schiziira, hut the fore wings scalloped; palpi rather slenderer and shorter; fore wings long and 
narrow. Larva with eudof body raised; a large double tubercle on lirst and a decided hump on eighth 
abdominal segment ; Xi/Unodee 
B. End of ^ autennm liliform; vertex tufted; palpi short and thick; wings often long and narrow, outer edge 
more or less obJhpie. Hind wings longer and more pointed than in lleterocampa. 
Larva; body somewhat eompressed, with two or three abdominal hnmi)s. often a V-sbaped, silvery dorsal 
mark in front of tlie last tubercle Schisura 
Differs sligfitly from Ileteroeampa in the venation, the subcostal cell being very long and narrow. Larva 
in last stage smooth, unarmed, noctuiform, very closely resembling that of If. mauteo Seirodonta 
Fore wings produced toward tlie apex, outer edge usually very oblique; a huig subcostal ceil; hind wings 
short and rounded; ^ antenrue filamental at the end. Larva varying from beidg siuq>ly noctuiform to 
having long substemapodiform anal legs lleterocampa 
Like lleterocampa, but with no subcostal cell. Larva with the anal legs converted into true hljimeutal 
processes (Stemapoda) like those of Ceriira Macrurocamxia
