236 Mr. L. B. Pi-out on 



of the ground-colour between SC 4 and SC 3 , and three 

 terminal ones, separated only by the veins, from SC 5 to R 3 , 

 the anterior one being short, the posterior triangular, the 

 grey colour running to the termen at R 3 . Hind wing almost 

 entirely clouded with leaden grey, leaving the margin green 

 from apex to R 3 and again from M 1 to tornus, and with the 

 faintest possible indications of a diffuse greenish postmedian 

 line or shade ; cell-spot black, distinct, somewhat elongate. 

 Underside without distinct markings. 



San Antonio, W. Colombia, 5800 feet (M. G. Palmer) ; 

 2 <$ c? , the tvpe dated December 1907, the other November 

 1907. 



Similarly marked to P. apicata, Schaus, Tr. Am. Ent. Soc. 

 xxvii. p. 251, which I select as type of the genus, but larger 

 and with some other differences. Schaus in defining his 

 genus gives " Palpi porrect, short " ; I do not think this is 

 applicable to any species of the group, though the palpus 

 is much shorter in the $ (from which Schaus evidently 

 diagnosed) than in the ? , in which the third joint is 

 extremely elongated. 



Racheospila tumefacta, sp. n. 



cJ . 23-25 mm. — Face above red, below white, more or 

 less marked with red, vertex white, occiput red ; palpus red, 

 first and second joints white beneath, third joint tipped with 

 white ; antenna! shaft white, pectinations pale ochreous. 

 Thorax green above, white beneath; legs white, marked with 

 red. Abdomen whitish beneath, purple-red above, with five 

 snow-white medio-dorsal tufts, the middle three large, subtri- 

 angular. Wings somewhat translucent green, fiuely irrorated 

 with white, costa of fore wing white from near base to about 

 two-thirds. Transverse lines whitish, fairly distinct in fine 

 specimens; first sinuate, from one-fourth costa to one-third 

 inner margin of fore wing, continued on hind wing; second 

 from near three-fourths costa, lunulate-dentate (the teeth 

 directed distad on the veins, the deepest lunule between M 2 

 and SM 2 ), reaching inner margin of fore wing at about two- 

 thirds, continued on hind wing with a projection between R 3 

 and M 1 . Fore wing with purple-red markings as follow : 

 a streak along costa, projecting a lunular mark which bounds 

 the second line proximally from SC 5 to R 1 ; an almost 

 angular cell-spot, filled in distally with lighter purple-red 

 shading, forming an irregular triangle ; and a streak along 

 distal margin, widening into conspicuous blotches from R 1
