pi. 11, fig. 80; pi. 13, figs. 99-112) ; aedeagus variable in shape, ranging 

 from being quite curved near apex and ending in rounded tip (pi. 7, 

 figs. 34-40; pi. 8, figs. 46, 47) to being somewhat truncate at apex 

 (pi. 7, figs. 41, 42; pi. 8, figs. 43-45, 48), or rarely being almost pointed 

 apically (pi. 8, fig. 50) ; commonly the apex has a small postgonoporal 

 notch and a large, gently curving, pregonoporal notch, but the reverse 

 also occurs; body pile short, even, obscure in some species; apex of 

 antenna usually with one seta; abdomen usually with typical fasciae 

 (pi. 5, fig. 29), but some species are maculated. This group was partly 

 defined by Sabrosky (1948, p. 409) as "#1, pallidipennis complex." 



Included species: 0. basalis (Walker), clavatus Becker, disjpar 

 (Macquart), dusmeti Arias, gibbosus (Linnaeus), pallidipennis Loew, 

 reginae Trojan, rufoabdominalis Cole, varius varius Latreille, varius 

 pallidimarginalis Brunetti, varius siberiensis Brunetti, and the follow- 

 ing new B^ecies: adaptatus, argentinensis, boharti, brasilensis, canadensis, 

 colombiensis, hennigi, orientalis, philippinensis, and sabroskyi. 



Group VI — ported group 



Diagnosis: Veins Mi, Ma, M4, and crossveins m-cu and r-m 

 absent; anal area greatly reduced as is veia R4+5; vein Ri and costa 

 also shortened (pi. 4, fig. 16) ; male genitalia have not been examined 

 in the only known specimen; body pile short and sparse; antennal 

 structure unknown; male abdomen patterned as in some species of 

 Acrocera with sinuated fasciae. 



Included species: 0. j^orfm Schlinger. 



Ogcodes (Ogcodes) species of Australian siibregion 



As Paramonov has prepared a revision of the Australian Acro- 

 ceridae (in press)', 1 shall not attempt to deal with this fauna at any 

 great length at this time. Sixteen species have been recorded from 

 Australia and Tasmania. From Austraha: basalis (Walker), casta- 

 neus Brunetti, darwinii Westwood, doddi W andoWeck, fortnumi West- 

 wood, Jratellus Brunetti, fraternus Brunetti, ignava Westwood, 'nsignis 

 Brunetti, variegatus Brunetti, mdoriensis Brunetti. From Tasmania: 

 ater White, flavescens White, nigrinervis White, pygmaeus Wliite, and 

 tasmanica Westwood. 



From this study it appears that at least three species groups are 

 present in this region; namely, the pallidipennis, colei, and possible 

 the brunneus gi-oups. Also, 1 have seen one female specimen of an 

 undetermined species in the new subgenus Protogcodes from Australia. 



' Since completion of my worlr, Paramonov's paper (1957) has been published. See appendix and bibli- 

 ography.
