ART. 9 TWO- WINGED FLIES OF TEIBE MILTOGRAMMINI ALLEN 13 



Female. — Front at narrowest, 0.25 of head width, in the single 

 specimen measured. PulviUi of fore feet less than one-half length of 

 last tarsal joint. Otherwise, save for usual differences of genitalia, 

 like the male. 



Length, 6 to 8 mm. 



Typ^'.^Male, in the collection of Prof. J. S. Hine, from Cameron, 

 La. " August 14-28, 1903. 



Allotype. — Female, in the collection of Professor Hine, same locality 

 and date as the type. 



Host relationships. — Unknown. 



Described from two males and one female from Cameron, La., 

 August 14-28, 1903, and three males from the same locality, July 7, 

 1905, all collected by Professor Hine, in whose honor the species is 

 named. 



The species is closely allied to Jloridensis, from which it may be 

 distinguished by the absence of red on the last abdominal segment 

 and the genitalia, the absence of preapical scutellars and median 

 marginal bristles on the first abdominal segment, and in having tlie 

 parafrontals setulose outside the frontal rows.

For this species the writer has accepted the synonomy of Coquillett 

 and Bezzi and Stein without examination of the types concerned. 

 The identity of the European with the North American form has 

 been verified by a comparison of tlie genitalia. 



Male. — Front at narrowest 0.215 of the head width (measurements 

 of four as follows: 0.21, 0.21, 0.21, 0.23); frontal vitta dull black, 

 narrowest at base of antennae; at the middle of front, almost as wide 

 as either parafrontal; inner frontal row of about thirteen bristles; 

 parafrontals golden pollinose; vibrissae two-thirds length of second 

 antennal joint above front edge of oral margin; facial ridges irregu- 

 larly bristW on lower lialf or less; antennae black, third joint slightly 

 longer tlian second; arista thickened on basal third; in profile, buccal 

 width equals parafacials and one-sixth the eye height; front projects 

 about one-fourth the eye diameter; proboscis slender, almost equaling
