New distribution record: 



Washington: 1 d', 1 9 , Spokane, Aug. 6, 1924 (A. L. Melander, ALM). 



Discussion: The male specimen from Washington has been com- 

 pared with the holotype (cf) and is certainly conspecific. Although 

 vittisternum is closely related to colei as stated above, it is undoubtedly 

 closer to the New Zealand species, leptisorna, in spite of the great 

 geographical separation (see discussion on the comparison of the New 

 Zealand and the North American faunae above). 



The female specimen from Washington does not differ structurally 

 from the male, as was found to be the case in colei (see above) . How- 

 ever, the female is not patterned as is the male but rather has the 

 entire abdominal dorsum light brown, venter mostly dirty whitish 

 brown, legs light brown, short abdominal pile, infuscated squama, and 

 the head about one-half as large as the male. Most of the female 

 characters agree with those found above for the female of colei, except 

 that vittisternum shows no venational differences between the sexes. 



From the phylogenetic standpoint, vittisternum is an interesting 

 species since it seems likely that it gave rise to alhiventris (Johnson), 

 which now forms the new subgenus Neogcodes (see text fig. 3). 



Ogcodes (Ogcodes) floridensis Sabrosky 



Ogcodes floridensis Sabrosky, Amer. Mid. Nat., vol. 39, p. 421, pi. 1, fig. 4, pi. 2, 

 fig. 19, 1948. 



Diagnosis: Species of group iv. Male abdomen patterned, with- 

 out tergal white fasciae; tergite ii entirely yellow, iii, iv with three 

 brown spots, the median one triangular; venter apparently mostly 

 yellow with faint lateral brown spots as in vittisternum, but no median 

 row of spots; halter black with yellow stalk; venation about as in 

 figure 21; male genitalia similar to vittisternum, but the aedeagus 

 more acuminate apically and somewhat broader subapically than in 

 plate 10, figure 63 (see Sabrosky, 1948, pi. 2, fig. 19). 



Type: Holotype d", Brevard County, Florida, Sept. 22, 1929 

 (Juhan Howard, USNM 58365). 



Discussion: Although this species is superficially related to vittis- 

 ternum, it is apparently closer to shewelU, and thus to the New Zealand 

 species nitens. I have not examined the holotype of floridensis, but 

 by studying its original description in connection with specimens of 

 nitens, shewelli, and vittisternum there seems to be little doubt of 

 this association. 



Although floridensis is at present known only from the holotype 

 male, this is not surprising since Ogcodes specimens in general are 

 very uncommon throughout the Austroriparian region. In fact, I 

 know of only two other records from Florida.
