Diagnosis. — The presence of only two radial veins in the forewing 

 distinguishes Tampa among the phycitine genera showing a reduced 

 tongue. 



Description. — Frons conical; labial palpi ascending, often porrect 

 in females, about three times eye diameter in males, 3}^ times in 

 females; maxillary palpi three-segmented, cylindrical, reaching frons 

 or nearly so; tongue reduced, usually visible between palpi; antennae 

 filiform in both sexes, somewhat thicker in male, female scaled dor- 

 sally and laterally, ventrally with short appressed cilia, male scaled 

 dorsally, ventrally wdth cilia about one-half segment wddth, hooked 

 at tips; ocelli absent. 



Forewing with 8 veins; Ri from near upper outer angle of cell, 

 R2+4 fused, from the angle; Mi from about one-third from top of cell; 

 M2+3 fused, from lower outer angle; Cui from just before the angle; 

 Cu2 from w^ell before the angle. Hindwing with 7 veins; Sc and Rs 

 long stalked: Mi from upper outer angle; M2+3 fused, long stalked 

 with Cui, from lower outer angle; Cu2 from just before the angle. 



Male genitalia with uncus tapering, broadly and bluntly rounded 

 apically; rather densely setose dorsally and laterally. Gnathos wdth 

 medial process small, simple, shallowly notched apically. Transtilla 

 complete, w^eakly sclerotized. Juxta crescent shaped, with pair of 

 lateral setose tubercles. Vinculum V-shaped, apex bluntly rounded. 

 Valve narrow, sides nearly parallel, apex rounded. Vesica unarmed. 



Female genitalia with ovipositor tapering distally, about twice as 

 long as wide. Apophyses slender, posterior about six or seven times 

 as long as their basal separation; anterior about 2}^ times as long as 

 their basal separation, diverging. Ductus bursae long, slender. Bursa 

 small, with a group of five to seven parallel barlike signae extending 

 anteriorly from ductus seminalis near posterior end. Ductus seminalis 

 from posterior end of bursa, tapering, then slender.

Diagnosis. — This is the only known species in the genus. 



Description. — Labial palpi with basal segments and ventral and 

 inner sides of second segments white, third segments and outer sides 

 of second dark brown to black; maxillary palpi, frons, vertex, sides 

 of occiput dark brown to black; dorsum of occiput, patagia, and
