NEOTROPICAL MICROLEPIDOPTERA, VII — OBRAZTSOV 229 



transversely strigulated with dark brown, arranged as follows: a 

 rotundate-subquadrate blotch on dorsum towards base, reaching 

 lower vein of discal cell; an oblique streak starting costobasad of this 

 blotch, closely touching it at base, and continued along discal cell to 

 above a second blotch; this latter, much larger than basal blotch, 

 also rests on dorsum and is irregidarly shaped; its upper margin is 

 narrowly excavated, dividing upper portion of blotch in two unequal 

 parts, external of them larger and rounded; basal upper part of blotch 

 with a minute angle on inner margin; within blotch a short, whitish 

 streak between veins AI2 and M3; a triangular, light gray dorsal area 

 between two mentioned blotches, opened costally and striated verti- 

 cally by three ferruginous lines joined together at vein A24.3 and 

 continued as two parallel lines along interspace between basal streak 

 and larger of blotches; a rather narrow, slightly curved ferruginous- 

 brown subterminal fascia starting at about three-quarters of costa 

 and reaching upper portion of tornus; a pale ferruginous shadow 

 dividing lengthways interspace between this fascia and largei- of 

 blotches; this shadow becomes somewhat olive in its upper portion, 

 and in subcostal area joins a dilated streak; costa narrowly edged 

 with ferruginous, and dark dotted beneath this edge; some concolorous 

 dots in subterminal area; cilia dark gray at base and whitish at tips. 

 Length of forewuig 12 mm. Hindmng pale cream-white, shining, 

 becoming brownish at termen; cilia white with gray dividmg line 

 at base, more distinct around wing apex. 



Male: Unknown. 



Female genitalia: Erectile sacs on sides of postsegmental membrane 

 of eighth abdominal segment (on the only preprepared slide they are 

 badly damaged) . Apophyses posteriores not dilated at tips; apophj^^ses 

 anteriores with tips slightly dilated. Entire area around ostium 

 bm'sae membranous. Antrum short infundibuliform, in cephalic 

 portion slightly narrower than adjacent portion of corpus bursae. 

 Corpus bm'sae \vith a large (on the slide somewhat folded), broad, 

 moderately sclerotized signum shaped as a plate rounded cephalically. 



Type: Holotype, female (genitalia on slide, prepared by A. Busck 

 on Apr. 24, 1929), La Florida, Costa Rica, 500 ft.; USNM 67370. 



Remarks: Very similar to cordigera Walsingham, but having the 

 front of the head whitish, markings of the fore wing darker, and the 

 shadows dividing the light interspaces more distinct. The upper 

 projection of the basal blotch is not as long as in cordigera, and does 

 not extend far distad. The genitalia are distingidshed by the ostium 

 bursae slightly narrower than the corpus bursae, and the apophyses 

 posteriores not dilated at tips.
