Diptera ete., p. 205. Since publishing my description of this species, 
based upon a single specimen, I have received a pair taken in 
Siskiou Co., Cal. by Mr. James Behrens. The three species are re- 
markably alike in the coloring of their body and wings, and yet very 
easily distinguishable. A description of the larva and pupa of the 
european species is given by Beling, Verh. Z. B. Ges. 1878, p. 45.

Java, is probably a Mongoma (see above, p..204) and ©. ornatis-
