 Diviana verecuntella Grossbecli, Bull. Amer. Mus. Nat. Hist., 



vol. 37, art. 1, p. 132, 1917. 



Forewing grayish ocherous with whitish transverse 

 line and more or less marked with brownish fuscous; in 

 paler specimens the ocherous tint predominates, in 

 darker one, the gray; antemedial line outwardly trans- 

 verse from costa, indented at median and lower folds, 

 in well-marked (pale) specimens bordered inwardly on 

 lower half by a large dark patch; subterminal line 

 rather near and parallel to termen, very slightly in- 

 dented at vein 6 and lower fold and with some dark 

 streaks bordering it near costa; discal spots distinct, 

 blackish; a row of blackish dots along termen. Hind 

 wings pale smoky fuscous. Alar expanse, 16-18 mm. 



Genitalia as given for the genus. 



Type localities: Charlotte Harbor, Fla. {nymphae- 

 ella, in AMNH, ex Rutgers); Fort Myers, Fla. {vere- 

 cuntella, in AMNH) . 



Food plant: Unknown. 



Distribution: Florida, Charlotte Harbor (Apr.), 

 Everglades (Apr.), Fort Myers (Apr.); Texas, San Be- 

 nito (Apr.); Connecticut, East River (July). 



The Hulst type in the Rutgers Collection is only a 

 fragment. One pair of wings, the antennae, and the 

 abdomen are missing; but there is no doubt of what it 

 represents. The alar expanse given by Hulst (21 mm.) 

 is too great. It is nearer 18 mm. The Connecticut 

 specimens (one male and six females in the National 

 Collection) are darker than those from Florida and 

 Texas, more grajrish, and with little or no dark shading 

 or blotches bordering the transverse lines. They show 

 no genitalic differences. 



114. Genus Cacozophera Dyar 



Cacozophera Dyar, Ins. Insc. Menstr., vol. 7, p. 58, 1919. 

 (Type of genus: Cacozophera venosa Dyar.) 



Tongue reduced but exposed. Antenna of female 

 pubescent, simple. Labial palpus upturned, short, 

 not reaching vertex; third segment acuminate, shorter 

 than second. MaxiUary palpus filiform. Forewing 

 smooth; narrowly elongate; 10 veins; vein 2 from well 

 before outer angle of cell; 3 and 5 connate from the angle; 

 4 absent; 6 from below upper angle of cell, straight; 8 

 and 9 stalked; 10 from the cell, approximate to the 

 stalk of 8-9 for some distance. Hind wing with vein 

 2 from well before lower outer angle of cell ; 3 and 5 con- 

 nate from the angle ; 7 and 8 anastomosed for most of their 

 lengths (8 very short); cell less than one-half the 

 length of the wing; discocellular vein curved. 



Female genitalia with bursa copulatrix large, finely 

 scobinate throughout, the scobinations extending part 

 way into the ductus bursae; signa present, consisting 

 of a cluster of small, slender disks (three in the only 

 specimen available) ; ductus bursae slightly shorter 

 than bm-sa, unsclerotized; genital opening simple; 

 ductus siminalis from bursa in the neighborhood of the 

 signa. 



The genus and its type species were erected on a 

 single female. Dyar characterized Cacozophera merely 

 as having the venation of his genus Anthropteryx, 

 differing only in having the "wings long and narrow, 

 trigonate, the apex pointed, not short and square." 

 Anthropteryx itself was also erected on a single female 

 and unfortunately is a freak with vein 4 absent from 

 one forewing. Dyar did not notice the other forewing 

 in which vein 4 was present and stalked with 5, the 

 normal condition for the specimen. For further dis- 

 cussion of Anthropteryx see page 313. The placement of 

 Cacozophera is tentative. Its relationship to the other 

 genera cannot be determined untU a male is discovered. 



413. Cacozophera venosa Dyar 



FiGTJHES 105, 950 



Cacozophera venosa Dyar, Ins. Insc. Menstr., vol. 7, p. 58, 1919. 



Forewing brownish fuscous, the area between costa 

 and cell and vein 6 uniformly dark; below vein 6 and 

 from end of cell the veins darkly outlined and the inter- 

 spaces between them contrastingly paler; subterminal 

 line distinct from vein 6 to inner margin, whitish, 

 evenly curved and parallel with termen; no dis- 

 tinguishable antemedial line or discal spots; a faint 

 yellowish white shade along inner margin and (under 

 magnification) a scattered dusting of dull rosy scales on 

 the dark areas; terminal dots blackish, large, inter- 

 venular. Hind wing smoky fuscous, the veins and 

 terminal margin darker. Alar expanse, 19 mm. 



Genitalia as given for the genus. 



Type locality: Cayuga, Guatemala (May, type in 

 USNM). 



Food plant: Unknown. 



Known only from the female type. Obviously a good 

 species but of uncertain affinities. 



Genera 115-117: Psorosina to Paconius 



[Venatlonal division A. Forewing with 11 veins; 10 from the 

 cell or connate or shortly stalked with stalk of 8-9; 4 and 5 

 approximate, connate or very shortly stalked. Hind wing with 

 vein 2 from before lower outer angle of cell; discocellular vein 

 curved or incomplete. Male genitalia with costa of harpe 

 produced; cornuti developed; transtilla incomplete or absent.]
