H() NEW NORTH AMERICAN ANTIIOMYIIDAE (DIPTERa) 



posterior excavation, the basal portion of surface bare. Mid femur with a 

 number of weak bristles on basal half of antero-ventral surface and a series 

 of longer bristles from base to well beyond middle on postero-ventral ; mid 

 tibia with one median posterior bristle; hind femur with a rather closely 

 placed series of very short erect bristles from base to apex, the apical two 

 or three much longer than the others; hind tibia with one antcro-dorsal and 

 one antero-ventral bristle, the latter usually a little apicad of the former; 

 apical antero-dorsal bristle absent. Wing rather acute at apex, third vein 

 ondhig in tij), fourth usually slightly curved forward, its apex very notice- 

 ablv proximad of apex of third. 



/'e/zia/c— Similar to male in chactotaxy of thorax and l)nstl!ng oi legs. 

 The frons is about one-third as wide as head at vertex, slightly widened 

 anteriorly, with the frontal triangle not extending much beyond middle; 

 the orbits are narrow, each with five or six bristles and a few short hairs. 



Length, 3 to 3.75 mm. 



7^ype._^; Waiikesan, Illinois, August 24, 1917, (J. R. Mal- 

 loch), [Illinois]. AUotyp(:.— 9 ; Algonquin, Illinois, October 2, 

 1895, (W. A. Nason). Paratypes.—l cT, Urbana, Illinois, Oc- 

 tober 22, 1916, in forestry of the University of Illinois; 2 males 

 Waukegan, Illinois, August 24, 1917; 2 males, without data; 1 9 , 

 Algonquin, Illinois, September 3, 1894, (W. A. Nason); 1 9, 

 Swarthniore, Pennsylvania, Octo])or 24, 1910. 



The type was taken on the shore of Lake Michigan, but evi- 

 dently the species is not confined to the vicinity of large bodies 

 of water, as the Urbana specimen was taken a mile or more from 

 the nearest moderately clean body of water.

/''(///«/('.— Sitiiilar in color (o tlie preceding species, except that the i)alpi 

 are largely yellowish basally, the apices of femora are more broadly pale 

 and the tibiae more extensively yellowish. The thorax has seven brown 

 vittae, the median one prolonged to apex of scutellum, the sulmiedian i)air 

 almost complete, and the lateral two on each side much shorter. 



Structurally similar to arcuala Stein, the frontal triangle is very long and 

 narrow, (;()nsi)icuously attenuate just in front of anterior ocellus; the anterior 

 irilra-alar bristle is not distinguishable from the discal setulae in type; and the 

 hind femur has only two antero-ventral bristles, rear ai)ex. Length, 5.5 mm. 



Type. — 9 ; Kingston, Jamaica, West Indies, April, 1891, (C. W.

Tliis genus is distinguished from its allies by having the hairs 

 coiiliiiucil down on parafacials below level of apex of secontl 

 antennal joint. The eyes are separated by about the same dis- 

 tance in both se.xes.
