56. Eemlptilocera jocarella (Schaus) 



FlQITBE 659 



Acrdbasis jocarella Schaus, Ann. Mag. Nat. Hist., ser. 8, vol. 11, 

 p. 245, 1913. 



Hemiptilocera jocarella (Schaus) Dyar, Ins. Insc. Menstr, vol. 7, 

 p. 42, 1919. 



Forewing reddish brown, the reddish (vinous) shade 

 predominant in cell and, broadly, along lower fold; a 

 dull olivaceous shade along costa and in terminal area; 

 antemedial line obsolete, indicated only by fragments of 

 its outer border (a black narrow streak from costa to 

 cell, a black spot on lower margin of cell, and a thin, 

 in-bent black streak from vein lb to inner margin); 

 subterminal line indicated by a pale black margined 

 spot on costa and an outward series of short whitish 

 streaks on veins 6 to lb, these spots inwardly and out- 

 wardly margined by black dots; a series of black dots 

 along termen (less distinct than in the other species of 

 the genus) ; the usual black discal spots, only the lower 

 one pronounced, and it but slightly so. Hind wing 

 glossy purplish or smoky brown; the veins but faintly 

 darkened ; a fine dark line along termen. Alar expanse, 

 21-26 mm. 



Female genitalia exhibit (in the amount of scobina- 

 tion of ductus bursae and the smaller size of signmn) 

 but trifling differences from those of letharda. The male 

 of jocarella is unknown. 



Ttpe locality: Avangarez, Costa Rica (type in 

 USNM). 



Food plant: Unknown. 



Distribution: Costa Rica: Avengarez (July). 

 PanamA: Porto Bello (Dec). Brazil: Nova Teutonia 

 (May). 



These records from four females in the U. S. National 

 Museum. When males can be associated it is quite 

 ikely that jocarella will prove to be only the female 

 form of plumigerella. 



57. Hemiptilocera exoleta (Zeller) 

 Figure 661 



Myelois exoleta Zeller, Horae Soc. Ent. Rossicae, vol. 16, p. 201, 



1881. 

 Hemiptilocera exoleta (Zeller) Ragonot, Monograph, pt. 1, p. 146, 



1893. 



This species is represented only by the female type. 

 I have seen nothing that matches Ragonot's description 

 or Zeller's rather crude figure; but from both and from 

 details of the female genitalia the reference is doubtful. 

 Ragonot himseK questions the correctness of his generic 

 placement; but in the absence of a male no better 

 placement could or can be made. 



The forewing shows the usual distinctively contrasted 

 row of terminal dots and the maculation otherwise is 

 that of a Hemiptilocera except that the usual discal dots 

 are replaced by a reddish lunule. According to Ragonot 

 the cell of hind wing is also short for a Hemiptilocera. 

 Alar expanse, 25 mm. 



The genitalia show a peculiar development of the 



eighth segment collar, a central-dorsal, invaginated, 

 sclerotized pocket flanked by a pair of irregular, elon- 

 gate, flattened lobes and on dorsum of ovipositor a pair 

 of shallow sclerotized pockets (fig. 661a). The genital 

 opening also is unsclerotized, lacking the usual ventral 

 shield. 



Type locality: Honda, Colombia (type in BM) . 



Food plant: Unknown. 



A male will be needed for certain generic placement. 



10. Genus Crocidomera Zeller 



Crocidomera Zeller, Isis von Oken, 1848, p. 865. — Ragonot, Mono- 

 graph, pt. 1, p. 132, 1893. (Type of genus: Crocidomera 

 turbidella Zeller.) 



Tongue well developed. Antenna pubescent; male 

 with a short, blimt, spine from upper outer angle of 

 basal segment of shaft; basal segment of male antenna 

 swollen and broadly scaled. Labial palpus upcurved, 

 reaching to vertex or slightly above it; third segment 

 over half as long as second, acuminate. Maxillary 

 palpus small, squamous. Forewing smooth; 11 veins; 

 vein 2 from well before lower outer angle of cell; 3 from 

 the angle ; 4 and 5 approximate for a short distance from 

 cell; 6 from below upper angle of cell, very slightly bent 

 towards base; 8-9 stalked for about half their lengths; 

 10 from the cell approximate to the stalk of 8-9; male 

 without costal fold. Hind wing with vein 2 from well 

 before lower outer angle of cell; 3 from the angle; 4-5 

 contiguous for about one-third their lengths beyond cell; 

 7 and 8 closely approximate beyond cell; cell slightly 

 less than half the length of wing; discocellular vein 

 curved. Eighth abdominal segment of male with com- 

 pound ventral and ventrolateral tufts. 



Male genitalia with apical process of gnathos an 

 elongate hook, blunt and rounded or slightly notched at 

 apex. Uncus broad, hoodlike, apical margin broadly 

 rounded or broad and truncate. TranstUla complete, 

 stout, arched, with a strongly forked central projection. 

 Harpe with costa rather broadly sclerotized, but not 

 produced at apex, clasper more or less developed, simple, 

 erect. AneUus with broad, dorsoventrally flattened 

 lateral arms. Aedeagus with longitudinal rows of 

 thornlike spines towards apex; penis with sclerotized 

 wrinklings, but otherwise unarmed. Vinculum stout, 

 slightly constricted from middle to moderately broad 

 terminal margin; sh'ghtly longer than broad. 



Female genitalia with signum developed as a small 

 scobinate cup-shaped patch; ductus bursae moderately 

 long (shorter than bursa), expanding gradually to the 

 wide genital opening and with some strong sclerotized 

 wrinklings before genital opening; lower margin of 

 genital opening sclerotized, wrinkled and more or less 

 finely scobinate; dense, fine scobinations on the dorsal 

 membrane behind genital opening; ductus seminalis 

 from bursa near junction of bursa and ductus bursae. 



A tropical American genus ranging as far north as our 

 Texas border and probably into southern Florida ; easily 

 distinguished by its genitalia and male antenna.
