Thorax dark brown, subshining, covered with yellowish brown pile 

 about as long as antennal segment iii; legs slender, not swollen, 

 coxae, tarsal apices, claws, and pulvilU brown, remainder light brown, 

 entirely covered with pile as on thorax, but gradually shortening 

 towards extremities, hind femur and tibia of equal length; wing 

 narrowed apically, nearly hyaline, faintly infuscated, veins dark 

 brown except Mi, base of M4, and anal, light brown or clear; crossvein 

 m-cu present, crossvein r-m absent, but base of Mi at this point long, 

 extending near M4, anal vein nearly joins Cug at mng margin (pi. 4, 

 fig. 15) ; squama large, opaque, snowy white, with dark brown margin, 

 halter knob black on Hght brown stem. 



Abdomen subshining, dark brown except light brown tergite i, 

 tergites iii and iv mth extremely narrow posterior white fasciae, 

 light brown stemites ii-vi, and large white lateral intersegmental 

 membranes between sternites i-v; tergites ii-iv covered with pile 

 (as on thorax) only on broad median area and narrow lateral margins ; 

 tergite v bare medially, but with similar pile on broad mesolateral 

 and marginal areas; tergite vi bare medially, but with some marginal 

 pile; sternite i shining, bare, 11- vi covered evenly with pile as on 

 dorsum, but shorter. 



Genitaha small; aedeagus nearly acuminate at apex, and with 

 distinct, subapical, ventral projection (pi. 9, fig. 60). 



Female: Unknown. 



Holotype: Male, Ohakune (WeUington), North Island, New Zea- 

 land, 1922-23 (T. R. Harris, 1923-303, BMNH). 



Remarks: Superficially, paramonovi looks Uke (Ogcodes) brunneus, 

 but its closest relative is no doubt an undescribed Australian species.'' 

 I take pleasure in naming this species after Dr. S. J. Paramonov, who 

 has recently contributed much to furthering acrocerid taxonomy. 



Subgenus Ogcodes {Ogcodes) Latreille, new status 



Ogcodes Latreille, Precis. Caract. Gen. Ins., p. 154, 1796. 



Type species : Musca gihhosa Linnaeus. 



Diagnosis: Antenna 3-segmented, terminal segment styliform, 

 usually with one apical seta, sometimes mth two or three, but never 

 with basolateral bristle; frons bisected medially, without pile; pro- 

 boscis (not visible in dead specimens) covered by thin oral mem- 

 brane; abdomen commonly brown or black with white posterior 

 fasciae on tergites, though often varicolored; legs sometimes with 

 tibiae (particularly T3) swollen distally. 



Discussion: Phylogentically, this subgenus divides into six species 

 groups as based on wing venation, male genitalia, antennal structure 



• This species has recently been described by Paramonov (1957) as hirtifrons (sec appendix).
