beyond (as in Oncolabis), otherwise flattened, on female 

 simple. Labial palpus oblique; long, second segment 

 extending above vertex, on male grooved to hold the 

 maxillary palpus; third segment porrect (deflected for- 

 ward). Maxillary palpus filiform. Forewing smooth; 

 10 veins; vein 2 from near lower outer angle of cell; 3 

 from the angle, approximate to 2 in the male, (closely 

 approximate or connate with 5 in the female) ; 4 absent ; 

 6 from slightly below upper angle of cell, slightly curved 

 in male (straight in the female); 8 and 9 stalked; 10 

 from the cell, approximate to 8-9 at base; male without 

 costal fold. Hind wing with vera 2 from lower outer 

 angle of cell connate with the stalk of 3-5; 3 and 5 

 stalked for half or (in female) slightly more than half 

 their lengths; 7 and 8 anastomosed for about half then- 

 lengths (more shortly anastomosed in female) beyond 

 cell; cell slightly under one-third the wing length; dis- 

 cocellular vein curved. The venation except for the 

 absence of vein 4 of forewing is strikingly similar to that 

 of Oncolabis, especially in the female. Eighth abdom- 

 inal segment of male with compound ventral tuft. 



Male genitaha similar to those of Oncolabis and 

 Ewrythmasis except for slightly longer vinculum (a 

 difference of, at most, specific significance). 



Female genitalia similar to those of Oncolabis; signa 

 strongly developed, consistiug of a large, roimd, curved, 

 densely spined plate and a few similar detached spines 

 near the plate; a fused collar of similar spines surroimd- 

 ing the ductus bursae at its jimction with bursa copu- 

 latrix; ductus bursae as long as bursa, minutely scob- 

 inate for about half its length beyond the collar; genital 

 opening simple; ductus seminalis from bursa near its 

 jimction with ductus bursae. 



410. Stylobasis rubripurpurea Hampson 

 Figures 106, 458, 946 



Stylobasis rubripurpurea Hampson, in Ragonot, Monograph, pt. 

 2, p. 198, 1901. 



The moth has the general habitus of Oncolabis 

 anticella; forewing purplish gray (or dark grayish 

 fuscous) with whitish costal streak sparsely dusted with 

 reddish scales; transverse lines obsolete, the antemedial 

 indicated below cell only by an outwardly bordering 

 pale yellowish patch. Hampson's description men- 

 tions faint blackish streaks from the base of costa and 

 on the median vein and one distinct discal spot. The 

 figure in Ragonot (pi. 49, fig. 19) is misleading. It 

 shows a form with the veins darkly outlined, a distinct 

 whitish subterminal line, and no trace of the yellowish 

 patch on inner margin, or of the pale costal streak. Our 

 female in the National Collection is rubbed so that the 

 dark ground color shows plainly only along the veins, 

 thus corresponding with Ragonot's figure. Alar ex- 

 panse, 16-19 mm. 



Genitalia as given for the genus. 



Type locality: "Irazu, Mexique" (type in Trans- 

 vaal Mus.) . 



Food plant: Unlcnown. 



In addition to the male type Hampson mentions a 



male from Santos, Brazil. These, in addition to the 

 female from Juan Viuas, Costa Rica (Apr., in USNM), 

 are the only specimens of the species known to me. 

 Through the courtesy of Dr. Janse I was able to see 

 and figure the genitalia of the male type. He also 

 submitted a drawing of the wing venation which is re- 

 produced here. The femple in the National Museum 

 tentatively identified by Schaus as rubripurpurea differs 

 in slight details of venation from the male type, as indi- 

 cated in the foregoing generic description, and may or 

 may not be conspecific. However, from its labial palpi 

 and the sum of its characters I believe it is properly 

 placed. 



112. Genus Diviana Ragonot 



Diviana Ragonot, Nouv. Gen., p. 27, 1888; Monograph, pt. 2, 

 pp. xii, 201, 1901.— Hulst, Phycitidae of N. Amer., p. 190, 

 1890. (Type of genus: Diviana eudoreella Ragonot.) 



Dannemora Hulst, Phycitidae of N. Amer., p. 212, 1890. — Hamp- 

 son, in Ragonot, Monograph, pt. 2, pp. xiii, 209, 1901. 

 (Type of genus: Dannemora edentella Hulst. New synony- 

 my.) 



Tongue short and weak, but exposed. Antenna 

 pubescent; on male, shaft curved toward base, some 

 rough scaling in the cm-ve (but no teeth or other spine- 

 like projections) . Labial palpus upturned, short, barely 

 reaching to vertex; the second segment tufted in front; 

 the third short, acmninate. Maxillary palpus squa- 

 mous (not fUiform as stated by Ragonot and Hampson) . 

 Forewing smooth; sub triangular, rather broad towards 

 termen; 10 veias; vein 2 from before the angle of the 

 cell; 3 and 5 closely approximate or connate from the 

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

 straight; 8 and 9 stalked; 10 normally from the cell and 

 approximate to the stalk of 8-9, rarely connate or very 

 shortly stalked with 8-9; male without costal fold. 

 Hind wing with vein 2 from before but near lower outer 

 angle of cell; 3 and 5 shortly stalked, from the angle; 

 7 and 8 anastomosed for a short distance beyond cell 

 (for half or less than half their lengths) ; cell less than 

 half the length of wing; discocellular vein ciurved. 

 Eighth abdominal segment of male simple. 



Male genitalia with apical process of gnathos a small 

 knob terminating in a short spiue. Uncus as broad as 

 long, lateral margins parallel, terminal margin bluntly 

 angled. TranstUla absent (elements not distinguish- 

 able). Harpe short, slender, very slightly tapering to 

 narrowly rounded apex; costa broadly sclerotized 

 throughout and terminating in a short, slender spine. 

 Anellus a broad, deeply and widely cleft plate. Ae- 

 deagus long, moderately stout, strongly sclerotized, 

 with a few scobiaations toward apex; penis armed with 

 two stout, straight cornuti (sHghtly less than one-third 

 as long as aedeagus). Vincvdum very stout, longer than 

 combined tegumen and imcus and considerably longer 

 than broad; very slightly tapering; terminal margin 

 broad, straight. 



Both Diviana and Dannemora were described from 

 males. As far as I know there are no known females of 

 either type species. In the Ragonot Monograph the 

 two supposed genera are widely separated in the generic
