342 Mr. T. D. A. Cockerell — Descriptions and 



to about four-fifths of length of first t.-c. ; second r. n. re- 

 ceived a short distance from apex ; marginal cell rounded 

 at apex ; outer upper corner of third discoidal approxi- 

 mately rectangular. Abdomen shining, with only very 

 minute and feeble punctures, hind margins of second and 

 third segments reddish. Hind tibial scopa red, abundant, 

 long and loose. 



Hab. Rio McClelland, Tierra del Fuego, 12. i. 1905 (R. 

 Craivshay). British Museum. Found " iu the face of the 

 cliff, on the sea-shore." 



This differs from Pasiphae, as originally defined, by the 

 large ocelli forming a curve rather than a triangle, the robust 

 antennse, the marginal cell obtuse at apex (though with a 

 very small appendicular nervure), and the labrum not emar- 

 ginate. Except for the slight appendage at the end of the 

 marginal cell, the venation agrees with that of BicoUetes 

 neoiropico, Friese (which is herewith designated as the type 

 of BicoUetes), but BicoUetes is scarcely to be separated 

 geneiically from Pasiphae. P. cijanea is readily known 

 from most species by its blue colour ; it is, perhaps, related 

 to P. ccerulescens, Spinola, which is unknown to me, and 

 seems not to have been found since it was described in 1851. 



CapicoJa (?) basutorum, sp. n. 



S . — Length about 12 mm. 



Slender ; head, thorax, and first abdominal segment black, 

 rest of abdomen dark reddish fuscous; mandibles reddish, 

 with the base pallid and yellowish ; clypeus black ; flagelluni 

 bright orange-fulvous, about the basal third black above ; 

 tubercles yellow ; coxse, trochanters, and base of femora 

 piceous, legs otherwise light yellow suffused with ferru- 

 ginous ; tegulse hyaline, rufo-testaceous. Wings smoky, 

 hyaline, and stained with orange basally ; stigma light 

 orange-ferruginous ; nervures fuscous, the subcostal black, 

 but the costal and other nervures toward base of wing ferru- 

 ginous. Labrum emarginate ; head broader than long, eyes 

 ])rominent ; face densely covered with light ochreous 

 hair ; antennse only moderately long, flagellum thick ; ocelli 

 rather large ; vertex with thin reddish hair; region on each 

 side of ocelli smooth, with few strong punctures ; thorax 

 with thin reddish hair ; mesothorax and scutellum shining, 

 with very large scattered punctures ; area of metathorax 

 with about ten very strong ridges, the intervals shining — 

 this region is bounded by an elevation, below which are 

 short oblique plicae. Wings large and ample ; marginal
