6 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 123 



Male genitalia as illustrated by figures 1b-e with harpes fused for 

 nearly one-half their length from base; with aedeagus distally curved 

 upward; with gnathal arm blunt and having a mesially placed carina; 

 lateral lobe of uncus very uniquely shaped, having a strong acute 

 projection from near lower angle and with a strong projection from 

 lower margin. Eighth tergite (fig. 1a) deeply incised in middle of 

 posterior margin, elongated anteriorly, and with posterior lobes 

 acute and toothed along inner sides. 



Female (pi. 2: fig. 1). — Forewing above dark brown with streaks 

 of shining blue in base of wing below and above vein 2d A. Hindwing 

 mostly bright shining blue except for a dark brown border extending 

 around outer margin from the anal angle to costa and except for a 

 dark brown ray extending through bottom of cell to outer margin just 

 above vein M 3 (in one specimen) and with more of this color below vein 

 Cui in anal area (in both specimens). With a white marginal line 

 above 2d A continued to vein Mi. Anal lobe with a small orange-red 

 spot. Wings underneath like those of the male except the black 

 centers of the marginal ocular markings in interspaces M 3 and Cu! are 

 distinctly smaller. 



Length of forewing 11 mm. 



Female genitalia as illustrated by figure 14 with ductus bursae and 

 bursa copulatrix relatively long, the longest of any species of Caly- 

 stryma, their combined length being about four times the width of 

 superior genital plate; the latter with free edge divided into two lateral 

 elements, each with a single pair of spurlike processes, the anterior 

 spurlike process being very large and sickle shaped, the posterior 

 spurlike process reduced in size and distally directed. 



Type-locality. — Limon, Province of Lim6n, Costa Rica. 



Additional type data. — Described from the holotype, male and 

 eight male paratypes with data as follows: holotype, localit} 7 as given 

 above, USNM type no. 34904, May, Collection William Schaus, 

 genitalia preparation WDF no. 3168; five paratypes, La Florida, 

 Costa Rica, March 1907, 500 ft., Collection William Schaus, genitalia 

 preparations WDF nos. 3171, 3172, 3980, 3981, 3982; two paratypes, 

 Guapiles, Costa Rica, September and May 1907, 850 ft., Collection 

 William Schaus, genitalia preparations WDF nos. 3173, 3979; one 

 paratype, Carillo, Costa Rica, Collection William Schaus, genitalia 

 preparation WDF no. 5012. [Note: Eleven additional males from 

 non-Costa Rican localities (Upper Rio Maranon, Peru, Chapare, 

 Bolivia) are identified as C. keta but are not labelled paratypes be- 

 cause of the remoteness of their localities. While the author is 

 satisfied that the two known female specimens upon which the above 

 description of that sex is based are associated correctly, they are 

 excluded also from the type series for the same reason.]
