Adult female in hreeding phttnage. — No. 147326, U.S.N.M. ; Bogota, 
Colombia. — Upper surface sepia, streaked with buffy and ochraceous,

This race is similar to chi'ysolpema^ but considerably smaller and 
more conspicuously streaked below; the cervix and bend of wing 
less pinkish. From oaxacse it may be distinguished b}- its much 
darker, less rufescent colors above, heavier streaking below, as well 
as by somewhat smaller size. 
Although not recognized by Dr. Dwight, this form of Otocoris is 
quite distinct. Notwithstanding that its range is a rather restricted 
one, and that it has no relative geographically nearer than Oaxaca, 
the differences between it and the other races are such as to make a 
trinomial best expressive of its relationship. 
The only specimens that have been seen are from the vicinit}' of 
Bogota, Colombia.
