innoxia; vinculum shorter (not over one and one-half times 

 the length of tegimien) and broader throughout than 

 that of innoxia. Female genitaha not exhibiting any- 

 specific characters to distinguish them from those of 

 _ innoxia. 



., Type locality: Dorado, Puerto Rico (type in Cor- 

 [ nell Univ. CoU.; paratype, c?, in USNM, 61394). 

 Food plant: Unknown. 



Described from male type and female paratype from 

 the type locality, collected May 30, 1930, by W. A. 

 Hoffman, and two male paratypes from Catano, Puerto 

 Rico, collected by Leonard and MUls, May 16 and July 

 24, 1930. 



Nothing is known of its life history, but its larval 

 habits are probably simUar to those of innoxia. 



619. Ribua patriciella (Dyar), new combination 



FlGTJBE 1116 



Ephestia patriciella Dyar, Ins. Insc. Menstr., vol. 6, p. 140, 1918. 



Forewing coloration similar to that of contigua, but 

 the reddish dusting more towards a brown shade and 

 less generally distributed; the veins outlined in blackish 

 gray which predominates over the red-brown on most of 

 the wing; transverse lines and discal spots obsolete. 

 Alar expanse, 12 mm. 



Female genitalia without sigmun. 



Type locality: Baracoa, Cuba (Oct.; type in 

 USNM). 



Food plant: Unknown. 



Known only from two specimens in poor condition, 

 the type and one female paratype from Santiago, Cuba 

 (May) . The labial palpi seem more oblique than por- 

 rect, but they are twisted so much that their shape can 

 not be accurately determined. The male is unknown. 

 The three males that Dyar included among his para- 

 types are Ephestia cautella.

Tongue weU developed. Antenna simple and pu- 

 bescent in both sexes. Labial palpus porrect. MaxU- 

 lary palpus minute, fihform. Forewing smooth; 9 

 veins; vein 2 from before, but near, lower outer angle 

 of cell; 3 from the angle; 4 absent; 5 appreciably sepa- 

 rated from 3 at base; 6 from below upper angle of cell, 

 straight; 8 and 9 united; 10 from the cell, separated from 

 8 at base; male with costal fold enclosing a scale tuft. 

 Hind wing with 2 from weU before outer angle of cell; 



3 and 5 connate; 7 and 8 anastomosed from most or all 

 of their lengths beyond ceU; ceU about half the length 

 of wing; discoceUular vein cm-ved. Abdomen of male 

 with two pairs of dorsal hair tufts, or compoimd dorsal 

 tufts on eighth segment. 



Male genitalia with apical projection of gnathos a 

 small knob terminating in a very short, simple, blunt 

 hook. Transtilla a narrow, curved, sclerotized band, 

 not in any way fusing to gnathos. Uncus for most of 

 its length rather narrow, its sides straight or but slightly 

 tapering to bluntly apical margin. Harpe with a very 

 slight, roimded projection from costa at middle and 

 a short thornlike projection at apex, otherwise simple. 



Female genitalia with ductus bursae flattened and 

 sclerotized for over half its length, shorter than bursa; 

 signa present, developed as a cluster of 3 to 5 contig- 

 uous, small, blunt, thornlike projections; ductus semi- 

 naiis from about middle of bursa, near signa. 



The genus is distinguished from Ribua by the follow- 

 ing combination of characters: Labial palpi of both 

 sexes porrect; veins 3 and 5 of forewing distinctly 

 separated at base; 10 from cell and not close to 8 at 

 base; 3 and 5 of hind wing connate; eighth abdominal 

 segment of male with two or more pairs of dorsal tufts ; 

 ductus seminalis from middle of bursa copulatrix. In 

 the Ragonot key to genera (Monograph, p. xiv) veins 3 

 and 5 of hind wing are said to be separate; but this is an 

 error. They are definitely connate. 



Plodia is a genus of definitely American origin. Its 

 type species has become cosmopolitan through trans- 

 portation in ship stores and the commercial distribution 

 of dried graias and fruits; but all its nearest relatives 

 (Ribua, Caudellia, Bethulia, etc.), and the only other 

 known congeneric species (dolorosa), are confined to the 

 New "World.
