Moodna, from which Dyar distinguished it. His diag- 

 nosis of Campyloplesis is in error in two important par- 

 ticulars: The male labial palpi are not "porrect" but 

 obliquely ascenting, almost upcurved; veins 3, 4, and 5 

 of forewing are not "stalked," 3 being only approximate 

 to the stalk of 4-5 at base and for a very short distance 

 beyond.

Moodnopsis decipiens Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 408, 

 1914. 



The two females from which the species was desmbed 

 (and the only specimens available) are rubbed so that 

 the forewing pattern cannot be clearly distinguished. 

 The ground color is a brownish gray (rather dark) with 

 a faint dusting of whitish scales along costa and (under 

 magnification) a scattered peppering of reddish scales 

 over most of the wing; antemedial line indicated only by 

 a rather broad dark outer border, this broken ; the sub- 

 terminal pale line faintly indicated, defined chiefly by 

 dark streaks on the veins before and beyond it, the inner 

 streaks rather long; discal dots faint but distinguish- 

 able, blackish; dots along terminal margin very faint 

 and more or less confluent. Hind wing pale fuscous; 

 the veins and terminal margin darker. Alar expanse, 

 27-28 mm. 



Female genitalia with signum large, the serrations 

 along projecting edge bluntly and rather broadly 

 rounded. 



Type locality: Orizaba, Mexico (type in USNM). 



Food plant: Unknown. 



In unrubbed specimens the dark streaking along the 

 veins would be more emphasized. Such lining of the 

 veins is characteristic of all the species in the genus; but 

 decipiens stands out because of its greater size and 

 darker ground color. 



557. Moodnopsis perangusta (Dyar), new combination 



Figure 573 



Euzophera perangusta Dyar, Ins. Insc. Menstr., vol. 7, p. 57, 1919. 



Ground color of forewing as in decipiens but trans- 

 verse lines more distinct; the antemedial line deeply 

 notched at lower fold ; the subterminal irregularly den- 

 tate and parallel with termen; dark borders of the trans- 

 verse pale lines narrower and dark lining of the veins 

 much less pronounced than in decipiens ; blackish discal 

 spots confluent; veins 4 and 5 longer stalked (for more 

 than half their lengths); 8 and 9 longer stalked and 10 

 closely approximate to the stalk of 8-9 for some distance 

 beyond cell ; costal fold extending to well beyond middle 

 of costa. Hind wings translucent white, gray toward 

 apex and along upper half of terminal margin. Alar 

 expanse, 25 mm. 



Male genitalia with bifurcation of apical process of 

 gnathos deeper, aedeagus smaller and less tapering, 

 vinculum broader at, and less constricted before, ter- 

 minal margins than those of other species in the genus. 

 The genitalic differences among the several species are 



better illustrated than described and can be readily 

 distinguished in the drawings. 



Type locality: Montserrat, Trinidad, British West 

 Indies (type in USNM). 



Food plant: Unknown. 



Known only from the male type. It is possibly the 

 male of decipiens. The size and coloration of forewing 

 would suggest this. The white hind wings and vena- 

 tion, however, would seem to indicate a distinct species, 

 though the differences noted may be only sexual. The 

 length of the stalking of veins 4 and 5 of forewing is 

 certainly unreliable, varying in individuals of species 

 where we have more than two specimens. 



558. Moodnopsis inornateUa (Ragonot), new combination 



Figures 574, 1061 



Zophodia inornateUa Ragonot, Nouv. Gen., p. 31, 1888; Mono- 

 graph, pt. 2, p. 25, 1901. 



The type of this species is a worn female from Costa 

 Rica without abdomen. In his original description 

 Ragonot gives the type locality as Brazil; but according 

 to Clarke this could easUy have been a misreading of a 

 smaU pin label with "Druce" inscribed on it. The 

 female in the British Museum is labeled "ty. original" 

 in Ragonot's handwriting and bears the further infor- 

 mation, "Irazu, 6-7,000 ft., H. Rogers." This must be 

 the type, for Dr. Burgogne states that it is not in the 

 Ragonot Collection at the Paris Museum. 



A photograph of the type agrees well with a series of 

 specimens in the National Museum (one male and three 

 females) from Juan Vinas, Costa Rica. 



The general color of the forewing is paler than that 

 of either decipiens or perangusta; but the markings are 

 similar, the dark lining of the veins, if anything, more 

 distinct. Worn specimens show no trace of an ante- 

 medial line, but in one of the females before me (in 

 better condition than the others) it is faintly outlined. 

 The male costal fold is shorter than in perangusta, 

 extending only to middle of costa. Hind wing of 

 female very pale fuscous; of male soiled white; veins 

 and edge of terminal margin darker. Alar expanse, 

 20-28 mm. 



The distinguishing characters of the male genitalia 

 are the shape of terminal projection of gnathos, the 

 shape of apical lobe of transtilla, and the constricted 

 vinciilum. The female genitalia are similar to those of 

 decipiens except that the signum is smaller and has 

 weaker, less rounded serrations along its projecting edge, 

 trifling differences of rather doubtful value. 



Type locality: Irazti, Costa Rica (type in BM). 



Food plant: Unknown. 



In addition to the Costa Rican specimens I have 

 before me a male from Santa Catarina, Brazil (July 22, 

 1935, Fritz Hoffmann, collector) which I take to be 

 inornateUa or a variety of it. The fore and hind wings 

 are considerably paler (more whitish) and the ante- 

 medial and subterminal lines more clearly indicated. 

 It is the same size as the male from Juan Vinas (20 

 mm.), has a costal fold of the same length, and agrees 

 with it in every genitaUc detail except that the forking
