is always distinguishable. The species can be identified 

 satisfactorily only by its venation and genitalia. Hind 

 wing pale smoky fuscous; veins and terminal margin 

 darker. Alar expanse, 11-13 mm. 



Male genitalia vdth prongs of apical process of gnathos 

 rather stout and curved towards each other at their 

 apices. Apices of elements of transtUla greatly de- 

 veloped, widely flaring. Harpe with transverse ridge 

 at base of cucullus projecting beyond lower margin of 

 harpe; lower margin of cucullus with a slight notch at 

 apex. Female genitalia with sclerotized band below 

 genital opening forming a rather broad oval shield; 

 ductus bursae much longer than bursa, sclerotized for 

 no more than half its length; dorsal sclerotized portion 

 of eighth-segment collar a rather broad band. 



Type localities: Juan Vinas, Costa Rica (muciella, 

 in USNM), Porto Bello, Panamd (sgualidella,ia\]SNM). 



Food plant: Unknown. 



Distribution: Costa Rica: Juan Villas (Feb.). 

 Guatemala: Cayuga (May). Panama: Corozal (Mar. 

 Apr., May), La Chorrera (May), Porto BeUo (May, 

 Dec). 



Dyar acknowledged the synonymy of muciella and 

 squalidella in his description of the latter. It is borne 

 out by their genitalia. Both types are females.

Figure 1085 



Calamophleps nodoses Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 343, 

 1914. 



Smaller and paler than muciella, with the dark borders 

 indicating the transverse lines fragmentary and obscure; 

 but chiefly distinguished by its genitalia. Alar expanse, 

 10 mm. 



Female genitalia with ductus bursae short (no longer 

 than bursa) and sclerotized for its entire length; dorsal 

 sclerotized portion of eighth-segment collar a narrow 

 band. 



Type locality: Corozal, Panamd (Apr., type in 

 USNM). 



Food plant: Unknown. 



Known only from the unique female type. 



585. Azaera lophophora (Dyar), new combination 



Calamophleps lophophora Dyar, Proc. U. S. Nat. Mus., vol. 47, 

 p. 343, 1914. 



Similar to muciella but darker, smoky gray; the 

 transverse lines and their dark borders more distinct. 

 May be only a dark form of muciella; but this cannot 

 be determined until more specimens are available, as 

 the two females of the type series (the only specimens 

 known) lack abdomens. Alar expanse, 11-12 mm. 



Type locality: Porto Bello, Panamd (May, type in 

 USNM). 



Food plant: Unknown. 



The female paratype is from La Chorrera, Panamd 

 (May). 



172. Genus Moodna Hulst 



Moodna Hulst, Phycitidae of N. Amer., p. 193, 1890. — Ragonot, 

 Monograph, pt. 2, p. xiii, 1901. — Hampson, in Ragonot, 

 Monograph, pt. 2, p. 267, 1901.— Forbes, Cornell Mem. 68, 

 p. 636, 1923. (Type of genus: Moodna pelviculella Hulst.) 



Tongue well developed. Antenna pubescent; shaft 

 of male with a short, shallow sinus towards base. 

 Labial palpus oblique, subcylindrical, reaching vertex, 

 somewhat rough scaled; third segment nearly as long 

 as second. Maxillary palpus filiform, short. Fore- 

 wing smooth; 10 veins; vein 2 from before, but rather 

 near, lower outer angle of cell; 3 from the angle; 4 and 5 

 stalked (for at least half their lengths), the stalk shortly 

 separated from 3 at base; 6 from below upper anglefof 

 cell, straight; 8 and 9 united (9 absent); 10 from the 

 cell, separated from 8 at base; male with a strong costal 

 fold enclosing hair tuft. Hind wing with vein 2 from 

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

 angle, connate, rarely (in individual specimens) very 

 shortly stalked; 7 and 8 anastomosed to or almost to 

 costa (8 absent or a mere vestige at costa) ; cell less than 

 half (but more than a third) the length of the wing; 

 discoceUular vein curved. Eighth abdominal segment 

 of male with compound, dorsal tufts. 



Male genitalia with apical projection of gnathos a 

 broad, short, pointed hook. Uncus broad; terminal 

 margin broad, straight or but slightly rounded. Trans- 

 tilla incomplete. Harpe with apex broadly rounded; 

 two strongly sclerotized subbasal projections from 

 costa. Anellus a narrow semicircular sclerotized band. 

 Aedeagus long, straight, not appreciably tapering, 

 simple; penis bearing one or two elongate, thin, weakly 

 sclerotized plates and a few sclerotized wrinklings, 

 otherwise unarmed. Vinculum long, triagulate. 



Female genitalia with signum a small cluster of 

 rounded, short, projecting discs; bursa copulatrix small, 

 wrinkled, the wrinklings weakly sclerotized; ductus 

 bursae long (much longer than bursa), sclerotized for a 

 short distance from genital openings; ductus seminalis 

 from bursa close to signum; an extended ventral lobe 

 from membranous area between ovipositor and eighth- 

 segment collar (figs. 1086a and 1087a). 



The species of the Moodna-Vitula complex ofl'er a 

 difficult problem in generic placement. Typical species 

 of either genus are obviously different in characters of 

 venation, genitalia, and male antennae; but there are 

 a number of aberrant species that possess characters of 

 both Moodna and Vitula and will fit in neither genus. 

 If we should attempt to unite all under one genus, we 

 should have a group that could not be defined. I have 

 therefore divided the complex into small units, resur- 

 recting Hulst's Manhatta and erecting separate genera 

 for some new species and the aberrant tropical species 

 that have been referred to Moodna, or misplaced else- 

 where. One name that appears under Moodna in our 

 fists (Ephestia nigrella Hulst) has veins 4 and 5 of fore- 

 wing united and is treated elsewhere in this paper as 

 Caudellia nigrella (p. 293). It has the habitus of 

 Moodna, similar male antennae, is similar in color and 

 maculation to its type, and is apparently derived from
