ART. 34 PLIES OF GENUS PSEUDOTEPHRITIS MALLOCH 3 



Penultimate section of fourth vein longer than the inner cross 

 vein; wing with one complete dark fascia, extending from 

 near the apex of the auxiliary vein to the apex of sixth, the 

 dark marivs over apex of first vein and one outer cross vein 



not connected 7. 



7. Basal pair of scutellar bristles reduced to fine hairs; the dark 

 marks on the costa very conspicuously darker than those on 

 the disk of the wing; visible tergites 2 to 4 of abdomen each 

 with a dark brown apical fascia, only the fourth with faint 



setigerous dark spots inaequalis new species. 



Basal pair of scutellar bristles as long and strong as the apical 

 pair; dark marks ou the costa not conspicuously darker than 

 those on the disk of the wing; all the abdominal tergites with 

 dark setigerous dots, second and third each with a pair of 

 dark marks in center at apex cribellum (Loew). 



Subgenus Pseudotephritis Johnson 



It is very probable that some subsequent worker will elevate this 

 and the other segregate of the genus to full generic rank as more 

 trivial characters than those cited for their distinction in the key 

 are accepted as of generic value in this family. For the present I 

 propose to consider them as merely subgenera, more closely related to 

 each other than either is to other genera in their immediate vicinity 

 in the family by the possession of the peculiar, and possibly sensory, 

 area on the hind tibia. It may be pertinent to note the occurrence 

 of somewhat similar areas on the same tibia in the great majority 

 of the genera in the subfamily Oscinosominae of the family Chlo- 

 ropidae, and of a peculiar elongate slitlike depression on the hind 

 tibia of many males in the famil}' Sepsidae, particularly in the 

 genus Tlicmlra Robineau-Desvoidy, the latter not having been men- 

 tioned, as far as I know, in print, though there are two recent 

 revisions of the family available. 



The type species of the genus, and also of the subgenus as at 

 present limited, is Ortalis van Say. The name StictocephaZa was 

 preoccupied by Stictocephala Stal and a new name proposed by 

 Johnson for that of Loew as above indicated.

I have seen this species from Texas, Virginia, Maryland, and Illi- 

 nois. It has also been recorded from Ohio, New Jersey, Maine, 

 Massachusetts, New York, and Montreal, Canada. It is probably 

 present over the entire eastern half of the United States and nortli 

 ward almost as far as hardwood trees are found.
