INSECUTOR INSCITI.^ MENSTRUUS 133 



(1916), Ind. Jn." Med. Res. IV, 138. Belongs in the Philsema- 

 tomyia group, as later pointed out by Awati, but differs from 

 all the other forms of the group in being larviparous. It is 

 immediately distinguished from Pristirhynchomyia, to which 

 it is most closely allied, by its well developed presutural dorso- 

 central bristles. 



Berendtia gen. nov. baltica sp. nov. (fossil). — Proposed for 

 Oestrus sp. Berendt (1830), Ins. Bernst., 34. From the Lower 

 Oligocene of Baltic amber. The description indicates affinity 

 with the Oestrine series of tribes. 



Giehelia gen. nov. ignota sp. nov. (fossil). — Proposed for 

 Oestrus sp. Giebel (1846), Palseozool., 278. From the Ter- 

 tiary, origin unknown. Description indicates affinity with the 

 Oestrine series. 



Himantostomopsis gen. nov. — Proposed for Himantostoma 

 hungarica Thalhammer (1897), Term. Fuezet. XX, 145. Dif- 

 fers from Diplopota Bezzi by the pilose parafacialia and the 

 arcuate course of fourth vein, 



Lithexorista gen. nov. scudderi sp. nov. (fossil). — Proposed 

 for Tackina sp. Scudder (1890), Tert. Ins., 554. From the 

 Eocene of Green River, Wyoming. The characters point to 

 a location somewhere in the Lydelline to Exoristine series of 

 tribes. 



Lithotachina gen. nov. (fossil). — Proposed for Bchinomyia 

 antiqiia Heer (1849), Ins Tert. Ceningen II, Nouv. Mem. Soc. 

 Helv. Sc. Nat. XI, 347-8, pi. 17, f. 17. From the Upper Mio- 

 cene of Oeningen. The characters indicate one of the Larvas- 

 vorini, perhaps closely allied to the existing genus Servillia. 



Neivsteadina gen. nov. — Proposed for Stomoxys fuscus 

 Walker (1849), List Dipt. Ins., Ill, 682. See Austen 

 (1911), Hdb. Tsetse Flies, 76, f. 17 A, for male hypopygial 

 characters; and Evans (1919), Ann. Trop. Med. Paras. XIII, 

 31-56, for female hypopygial characters. The fusca group has 

 long been recognized on male hypopygial characters ; it may be 

 recognized in the female by the dorsal plates being present and 

 the mediodorsal plates absent. 



Paleostomoxys gen. nov. giebelii sp. nov. (fossil). — Pro-
