2. PsEUDOcuLicoiDEs cixcTus Coquillett 



Ceratopogon cinctus Coquillett, Proc. U. S. Nat. Mus., Vol. 25, 1902, p. 81. 



The thorax of this species is entirely covered with dense priiines- 

 cence, and is without traces of vitta;. The hypopygium is as shown in 

 Figure I/, Plate XXI. 



Length, 1-1.5 mm. 



I have seen two males and one female, taken by Mr. Hart at Little 

 Bear Lake, Grand Junction, Mich., July 15, 1914. 



Originally described from Lake Worth and Biscayne Bay, Florida, 

 and recorded as biting human beings. 



3. PSEUDOCULICOIDES MAJOR, n. sp. 



Male. — Differs from imitabilis in being larger, 2 mm., in hav- 

 ing the thorax with four brownish vitta^, the center pair posteriorly 

 and the outer pair anteriorly abbreviated ; the halteres black or brown 

 with the apices of knob white, and the hvpopvgium as in Figure 9, 

 Plate XXL 



Female. — Similar to the male in coloration. 



Length, 2 mm. 



Type locality, Urbana, 111., July 2, 1914, at light (J. R. Malloch). 

 Allotype from Ithaca, N. Y. (O. A. Johannsen). 



The scutellum in both specimens is suffused centrally with brown, 

 and the anterior angles of the thorax are not so distinctly yellow as in 

 the majority of the specimens of luutabilis before me, but this charac- 

 ter is subject to some variation and can not be depended on. 



4. PSEUDOCULICOIDES JOHANXSEXI, U. Sp. 



Male. — Agrees with major in coloration and size, but differs ma- 

 terially in shape of the hypopygium (PI. XXL Fig. 10). 



Type locality, Palo Alto, California. Submitted by Prof. O. A. 

 Johannsen, after whom the species is named. 



Female unknown. 



This species and cinctus are inserted here to complete the genus, 

 though neither has been found in Illinois. 



FoRCiPOMYiA Meigen 



This genus was erected by Meigen for the reception of two species, 

 the type being designated by Coquillett as ambigiiiis Meigen.*
