Hob. Guatemala, San Geronimo (Champion) ; Costa Eica, Irazu 6000 to 7000 feet 

 (Sogers). — South America x . Three females. 



No Chiromyza has been found so far north before. In the Central-American examples 

 the four posterior tibiae are almost whitish in the middle, both ends being brown (I do not 

 find this character mentioned in the descriptions) ; the two first veins, issuing from the 

 discal cell, are nearly straight, by no means so much curved as in Wiedemann's figure ; 

 the third vein, on the contrary, which is represented as straight, is gently curved in our 

 specimens.

CHRYSOPILA. 



Chrysopila, Macquart, Dipt, du Nord &c. 1827. 



The four species of this genus which I find in the collections before me bear the 

 general character of the smaller dark-coloured forms, and are often clothed with a 

 golden pubescence. They seem to be numerous both in North and South America, but 

 are not readily recognizable from descriptions. For this reason I abstain from describing 

 any new species, especially as the specimens are not well preserved. 



l. Chrysopila ? 



Hob. Costa Eica 6000 to 7000 feet (Sogers), Irazu. Two males. 



Comes near Chrysopila basalis, Walk. Trans. Ent. Soc. n. ser. v. p. 284 (Mexico), but 

 I do not see any dull testaceous stripes on the thorax. The stigma is yellowish-brown
