102. Honorinus, new genus 



Type of genus: Honorinus fuliginosus, new species. 



Characters of Honora except: Labial palpus of male 

 grooved to hold the maxillary palpus; maxillary palpus 

 of male in the form of an aigrette ; forewing with vein 2 

 from before but near outer angle of cell ; hind wing with 

 cell shorter, somewhat less than one-third the length of 

 wing; transtiUa complete; abdomen of male with two 

 pairs of ventrolateral hair tufts. 



Very close to Honora. In the absence of any typical 

 species of Honora from tropical America and because of 

 the divergence of the Peruvian species on male charac- 

 ters it seems better to give it a separate generic desig- 

 nation than to expand and loosen om- definition of 

 Honora. 



397. Honorinus fuliginosus, new species 

 Figures 450, 947 



Forewing sooty fuscous; transverse lines obsolete or 

 nearly so ; antemedial line faintly indicated in the male 

 near inner margin; beyond it a faint ocherous shade; 

 some pale scaling between the veius beyond cell; a 

 narrow, obscure ocherous shade along costa from base 

 to middle; discal and terminal dots obscure. Hind 

 wing semihyaline, whitish fuscous with a dark line 

 along termen and some dark shading on the veins; 

 veins 3 and 5 stalked for more than half their lengths. 

 Alar expanse, 24-26 mm. 



Male genitalia with elements of transtiUa sohdly 

 fused at their apices to form a high, narrowly rounded 

 arch. Female genitalia with the membrane of posterior 

 lobe of bursa thickened. 



Type locality: Angasmarca, Peru (type in USNM). 



Food plant: Unknown. 



Described from male type and three male and one 

 female paratypes, all from the type locality. In addi- 

 tion I have before me another female from Mima, Peru, 

 which I take to be the same species; but as it has veins 

 3 and 5 of hind wing somewhat longer stalked and a 

 slightly smaller genitalia than the female paratype I do 

 not include it among the types. The males are rubbed 

 and do not show the dark ground color as plainly as the 

 female, which is in good condition. 



103. Genus Oncolabis Zeller 



Oncolabis Zeller, Isis von Oken, p. 877, 1848. — Ragonot, Mono- 

 graph, pt. 1, pi. 1, fig. 26, 1893; pt. 2, p. xi, 1901. — Hampson, 

 in Ragonot, Monograph, pt. 2, p. 187, 1901. (Type of genus: 

 Oncolabis aniicella ZeOer.) 



Endommasis Hampson, in Ragonot, Monograph, pt. 2, pp. ix, 

 124, 1901. (Type of genus: Endommasis nigritella Hamp- 

 son. New synonymy.) 



Tongue well developed. Antenna pubescent; basal 

 segment elongate ; on male, shaft with a stout hook from 

 its basal segment and strongly cm'ved for a few seg- 

 ments beyond (fig. 454d); on female simple. Labial 

 palpus obhquely ascending; long, extending half its 

 length above vertex ; smooth scaled ; segment 2 in male 

 grooved to hold maxiUary palpus; segment 3 very short, 

 acuminate, not deflected forward. Maxillary palpus 



of male in the form of an aigrette; of female filiform. 

 Forewing smooth; narrowly elongate; 11 veins; vein 2 

 from near lower outer angle of cell; 3 from the angle; 

 4-5 stalked for half their lengths, their stalk very closely 

 approximate or connate with 3 at base; 6 from below 

 upper angle of cell, straight; 10 from cell, closely ap- 

 proximate to the stalk of 8-9 for a short distance ; male 

 without costal fold. Hind wing with vein 2 from very 

 close to lower outer angle of cell; 3 and 5 stalked for 

 half their lengths ; 7 and 8 contiguous or closely approxi- 

 mate for a short distance beyond cell; cell one-third the 

 wing length; discocellular vein curved. Eighth ab- 

 dominal segment of male with compound ventral tufts. 



Male genitalia with apical process of gnathos a 

 stout, elongate, pointed hook. Uncus triangulate ; apex 

 pointed. Harpe elongate, slender; apex rounded; 

 clasper vertical, pointed. Anellus a small triangulate 

 cupped plate without lateral lobes. Aedeagus stout, 

 straight, moderately long; penis armed with a few short 

 sclerotized folds and numerous granulations. Vin- 

 culimi stout, a trifle longer than broad, not appreciably 

 tapering to broad terminal margin. 



Female genitalia ^vith signa strongly developed, 

 consisting of a large, round, cm'ved, densely spined 

 plate and a varying number of detached spines opposite 

 the plate; ductus bm-sae about the same length as 

 bursa, with a ring of sclerotized spinose ridges at its 

 junction with biu-sa, minutely granulose for a short 

 distance beyond; genital opening simple; ductus 

 seminalis from bursa near its jimction with ductus 

 bursae. 



Hampson distinguished his Endommasis from 

 Oncolabis chiefly on the shape of the labial palpus, 

 upturned ("redress^") in Endommasis and obliquely 

 erect with third segment projected forward in Oncolabis. 

 On the strength of this supposed difference the genera 

 were widely separated in the generic key in Ragonot's 

 Monograph (pp. ix and xi). This difference was solely 

 due to the position of the palpi at time of death of the 

 particular specimens. The normal position of the labial 

 palpus is appressed to face with third segment erect. 



Similar male antennae and female genitalia occur in 

 Stylobasis Hampson. The latter, however, is distin- 

 guished by its forewing venation, vein 4 being absent.

Forewing dark brownish fuscous with basal area 

 darker, blackish; costal border (except in suffused 

 specimens) whitish finely dusted (under magnification) 

 with scattered reddish scales; antemedial line obsolete, 

 indicated only by a white spot extending from lower 

 fold to inner margin and having a small, central, black 

 dot; in fresh specimens the white spot narrowly 

 bordered inwardly and outwardly by a faint ocherous 

 shading. Suffused specimens show little or no trace of
