FLIES OF THE GENUS OGCODES — SCHLINGER 257 



hrunneus on the basis of their coloration were found to be consimilis on 

 the basis of their genitalia. Thus, some confusion still exists between 

 these two species. 



Brunetti (1926) apparently had at least three species included 

 under hrunneus, and thus his distribution records should be queried. 

 Certainly his remarks about the specimen from "Gollans Valley" 

 refer to nitens (Hutton), unless it was a female, in which case it 

 may possibly have been argigaster, new species. Brunetti compared 

 his consimilis to basalis, a species which has never been recorded from 

 New Zealand. If he had compared it to hrunneus he would have no 

 doubt seen the great similarity between the two species. Judging 

 from Paramonov's (1955) key and from the writings of Hutton and 

 Maskell, hrunneus of Paramonov was not the same as that of Hutton 

 (1881, 1901) unless Paramonov had an extremely dark example. A 

 solution to the identity of these two species becomes more complex 

 because specimens of both "species" that were collected on the same 

 day at Ohakune, New Zealand, have been examined. Also, if the 

 type specimen of hrunneus should be a female, as I suspect it is, the 

 problem of knowing the true identity of these two species will become 

 even more acute. 



Maskell (1888) and Dumbleton (1940) have described and figured 

 the first-instar larva of hrunneus, and Dumbleton recorded Matachia 

 ramulicola Dalmas as a host. 



Specimens examined: Icf, 8 9. 



New Zealand: Ohakune, Wellington, North Island, 1 o', Jan. 15, 1920 (T. 

 Harris, USNM); 6 9, January 1924 (T. R. Han-is, BMNH); 2 9, March 1922

Type locality: Mount Ruapehu, North Island, New Zealand

Diagnosis: A species of group i that differs from hrunneus onl}- in 

 the male as follows : Tergites i and ii typically black, rather shining, 

 other tergites dark brown; male genitalia with aedeagus much 

 narrower and more pointed at apex (pi. 10, fig. 67); ejaculatory 

 apodeme of different shape (pi. 11, fig. 75; pi. 12, fig. 83), median 

 plate with rodlike sweUing. 



Discussion: As brought out under hrunneus, there is some con- 

 fusion about the distinctness of consimilis and the former, but several 

 typical males have been examined from Kumara and Blackball. On 

 the other hand, a topo typical male of consimilis had some of the
