of the ground-colour between SC and SC°, and three 

 terminal ones, separated onh' by the veins, from SC'' to R-', 

 the anterior one being short, the posterior triangular, the 

 grey eolour running to the termen at R". Hind wing almost 

 entirely clouded with leaden grey, leaving the margin green 

 from apex to R'' and again from AP 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? (J 5 the type 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, sJiort " ; I do not think tliis is 

 applicable to any species of the group, though the palpus 

 is much shorter in the cJ (from which Schaus evidently 

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

 extremely elongated. 



Racheospila tumefacta, sp. n. 



(J . 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, finely 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^ 

 and SM-), reaching inner margin of foi'c wing at about two- 

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

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

 a streak along costa, projecting a lunular mark which bounds 

 the second line proximally from SC'^ to R^ ; 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'
