AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE

key on the alternative of vein 10 of forewing from the 

 cell or from the stalk of 8-9, an unreliable character at 

 best and in this instance thoroughly misleading. In 

 two males before me (perfect matches for the figure of 

 eudoreella in the Monograph, pi. 23, fig. 12) vein 10 is 

 both ways, from the cell on three forewings and dis- 

 tinctly stalked on one (compare figs. 103 and 103a). 

 On the Hidst type of edentella it is stalked. 



Hampson's characterization of Dannemora in the 

 Monograph is false in a number of details. He included 

 in the genus (in addition to its type species) Euzophera 

 quadripuncta Zeller, of which he had only females, and 

 selected "characters" from both species and added a 

 "character" possessed by neither, namely, a circular 

 hyaline depression in the cell on the underside of hind 

 wing. There is no such structure in edentella or quadri- 

 puncta. The male of the latter has a depression in the 

 cell of hind wing, but it is not hyaline, is on the upper 

 surface of the whig, and is filled with dense, modified 

 sex-scaling. Hampson did not know the male, and the 

 hind wdng of the female is simple, so it is difficult to see 

 where he got this "character." Zeller's species is not 

 even closely related to edentella. I am treating it else- 

 where (p. 276). Ragonot's characterization oi Diviana 

 is misleading in one particular. He states that there are 

 some teeth ("dents") in the sinus of the shaft of the 

 male antenna. Such a character is present in Palatka 

 nymphaeella (Hulst); but I do not think he could have 

 had an example of this species before him imless his 

 description of eudoreella is incorrect and his figure of it 

 completely false.

 (misspelling). 



Forewing blackish brown, the median area heavily 

 dusted with white, giving it an ashy gray appearance; 

 antemedial white line nearly straight, slanting out- 

 wardly from costa to inner margin, slightly notched at 

 lower fold, bordered outwardly by a blackish line which 

 expands to a triangular blotch at costa, a similar, some- 

 what smaller blotch bordering the fine at inner margin ; 

 subterminal white line parallel to termen, notched at 

 vein 6 and at lower fold, towards costa bordered in- 

 wardly by a fuscous streak; discal dots at end of cell 

 distinct, blacldsh ; enthe outer area between subterminal 

 line and termen blackish brown. Hind wing pale smoky 

 fuscous, with a darker line along termen and some very 

 faint dark shading on the veins. Alar expanse, 16-19 

 mm. 



Male genitalia as given for the genus. 



Type localities: "America Septentrionalis" {eu- 



doreella, in Paris Mus.); Florida (Apr.; edentella, in 

 AMNH, ex Rutgers). 



Food plant: Unknown. 



Known only from males. The Hulst type is badly 

 rubbed and shows little trace of original markings; but 

 its genitaha agree in every detail with those of two well- 

 marked specimens (in USNM) from Orlando, Fla. 

 (Feb.), and Plummers Isl., Md. (July). These two 

 specimens are in perfect agreement with Ragonot's 

 figure of eudoreella. 



113. Genus Palatka Hulst 



Palatka Hulst, Canadian Ent., vol. 24, p. 62, 1892; U. S. Nat. 

 Mus. Bull. 52, p. 433, 1902. (Type of genus: Divinia nym- 

 phaeella Hulst.) 



Tongue reduced (better developed in female than 

 male). Antenna pubescent; shaft of male with a 

 shallow sinus at base containing a weak scale tuft and 

 a couple of short teeth concealed within the tuft (these 

 teeth are strongly sclerotized, pointed, dorsal projections 

 from two of the segments) ; shaft of female simple. 

 Labial palpus oblique, extending well above vertex; 

 broadly scaled; segment 2 long; segment 3 about one- 

 third the length of 2, acuminate. Maxillary palpus 

 filiform . Forewing smooth ; 1 veins ; vein 2 from before 

 the angle of the cell; 3 from the angle; 4 absent; 5 from 

 slightly above the lower angle and separate from 3; 6 

 from below upper angle, straight; 8 and 9 stalked; 10 

 from the cell separate at base from stalk of 8-9; male 

 without costal fold. Hind wing with vein 2 from well 

 before lower outer angle of cell; 3 and 5 from the angle, 

 very closely approximate towards base; 7 and 8 closely 

 approximate for half their distance beyond cell; cell 

 about one-half the length of wing; discocellular vein 

 curved. Eighth abdominal segment of male simple. 



Male genitalia with apical process of gnathos an 

 elongate, narrow hook. Uncus longer than broad, with 

 terminal margin broadly rounded. Transtilla incom- 

 plete, elements minute. Harpe elongate, narrow, grad- 

 ually tapering to bluntly pointed apex; saccidus pro- 

 duced at extremity into blunt, free arm directed towards 

 costa. Anellus a broad flattened plate. Aedeagus 

 long, moderately stout, smooth; penis armed with two 

 stout cornuti, about half as long as aedeagus. Vincu- 

 lum stout, slightly longer than broad, tapering to 

 broadly rounded terminal margin. 



Female genitalia with bursa copulatrix scobinate but 

 without signa, thickened (but not sclerotized) at ter- 

 minal end; ductus bursae shorter than bursa, strongly 

 sclerotized from jimction with bursa for a little more 

 than half its length, on ventral surface at genital open- 

 ing a broad, strongly sclerotized, triangulate plate; 

 ductus seminalis from bursa near its junction with 

 ductus bursae. 



The genus is quite distinct from others of venational 

 group D and easily identified by its male and female 

 genitalia. It is closest to Diviana, from which it is 

 readily separable by its hind wing venation, veins 3 and
