NO. 7 RICHARDS : THE GENUS BULIA WALKER 259 



also dark, the hind wing as in the male, the fore wing dark but with the 

 maculation faint. The second female is lighter, the fore wing nearly im- 

 maculate except for the darker reniform and the light subterminal line ; 

 hind wing light but with broad dark band on outer margin to vein 2 

 (Cu,). 



Expanse: 33-35 mm. 



Male genitalia: (pi. 32, fig. 7) Sacculus with small basal lobe and 

 short distal production. Juxta rounded. Aedoeagus with both spines large, 

 no external spiculations. 



Female genitalia: (pi. 33, fig. 2) Sternite VII shallowly indented 

 and with short, broad median prong which is not longer than the lateral 

 lobes. Bursa copulatrix weakly spined. 



Distribution: Types (lost) and 1 cT neotype from Mazatlan, Sina- 

 loa, Mexico (neotype, December 20, 1916) ; 1 c?, "Avangarez," Costa 

 Rica, July (Schaus and Barnes) (in U.S.N.M.) ; 1 ?, "Avangarez," 

 Costa Rica, June (Schaus) (in U.S.N.M.) ; and 1 $, aboard ship bound 

 from Corinto, Nicaragua, to White Friars, Mexico (islands opposite 

 Petatlan Bay, Guerrero), February 8-14, 1932 (John S. Garth) (in 

 Allan Hancock Foundation, The University of Southern California). 



There is some question as to the exact location of "Avangarez," Costa 

 Rica. Presumably this is the Abangares of the Pittier map of 1903 and 

 the American Geographical Society map of 1937, but aside from the 

 slight difference in spelling the older map locates this town at sea level 

 at the mouth of the Rio Abangares, while the more recent map has 

 nothing at this location but gives Abangares about 10 miles up the Rio 

 Abangares at an elevation of about 600 feet (approximately Long. 85° 

 W, Lat. 10° 15' N). Even so, both the evidence and Dr. Schaus' recol- 

 lection place these specimens as from the Pacific slope at a low elevation. 

 Mazatlan is at sea level, and of course the specimen taken aboard ship was 

 at sea level. So all the known specimens come from at or near sea level 

 on the Pacific slope from Mazatlan south to Costa Rica (Lat. 23° to 10° 

 15' N). No other species is known near sea level in this area. 



Bulia schausi, new species 



Since this species can be separated satisfactorily only by genital struc- 

 ture, a formal description of the maculation is not given. The holotype 

 male is similar to fig. 10 of pi. 5 of Entomologica Americana, volume 19, 

 but the fore wing is less contrasty on account of blackish suffusion, the
