CHETSOPILA. 61 



and not remarkably large ; the wings, on the distal half, are almost imperceptibly tinged 

 with greyish. About 6 millim. long. 



The Chrysopila apicalis, v. d. Wulp, Tijdschr. &c. xxv. p. 119 (Guadeloupe), is still 

 nearer; but I am by no means certain of the identity. Van der Wulp's name is pre- 

 occupied by Eondani for a South- American species. 



2. Chrysopila ? 



Hab. Mexico, Northern Sonora {Morrison). 



A pair ( <s $ ) from the above locality cannot be identified with any of the described 

 species. Blackish-grey, with hyaline wings, yellowish tibiae, black halteres, &c. 



3. Chrysopila ? 



Hab. Costa Eica, Irazu 6000 to 7000 feet (Bogers). 



A pair ( 6 $ ) from Irazu are certainly different from all the described species, but too 

 badly preserved for description. The wings have a brown cross-band issuing from the 

 darker brown stigma, crossing the middle of the first posterior cell, and reaching, some- 

 what attenuated, the cross-vein at the base of the fourth posterior cell ; between this 

 cross-band and the apex, which is likewise brown, there is a distinct hyaline cross-band. 

 In our male specimen the brown is more spread out than in the female, and the hyaline 

 band is cut off posteriorly by an infuscation of the last of the veins, issuing from the 

 discal cell ; in the female the brown markings are fainter and narrower, and therefore 

 the hyaline cross-band broader, but less distinctly marked. Anal cell short, petiolate ; a 

 distinctly yellowish tinge at the proximal end of the stigma. Body brown in the female, 

 with a golden-yellow pubescence, apparently forming double spots at the bases of the 

 abdominal segments ; I do not perceive any traces of this in the male. Halteres with a 

 brown knob ; legs brownish-yellow, the tarsi darker. Antenna? brown, the second joint 

 reddish. Length 7-8 millim. 



A third specimen (E. Sucio, Costa Eica, Bogers), a female, apparently belongs to 

 the same species, but the brown markings on the wings are still fainter, and the brown 

 cross-band almost obliterate. 



4. Chrysopila ?, <$ $ . 



Hab. Mexico, Ciudad in Durango 8100 feet (Forrer). 



Two specimens. Body brown ( <s ), or greyish-brown ( .9 ), with very scarce 

 yellowish pile ; antennae dark brown ; femora brown, the tibise brownish-yellow. Wings 

 altogether hyaline, the stigma brown. Length 6-7 millim.
