150 Phoridae. 



subdivided the old genus Phora, he correctly reserved this name for 

 the oldest species, abdominalis and its allies; as it later on was shown 

 that Trineura Meig. was a synonym of Phora Latr., the genus Trineura 

 with aterrima Fabr. as type thus got the name Phora, and so the 

 group of species left in Phora by Malloch was without name, and 

 there was no old name to be used for it after priority. In 1898 Dahl 

 (Sitzungsber. Gesell. naturf. Freunde, Berhn 1898, 188) had created 

 the genus Dohrniphora for the species Dohrni from Bismarck Archi- 

 pelago. It now proved that this species was congeneric with the 

 group of species in question, and Malloch, therefore, in 1912 (Proc. 

 U. S. Nat. Mus. 43, 430) correctly united them in the genus Dohrni- 

 phora with Dohrni as type. That D. Dohrni is congeric with the other 

 species is evident; Dahl laid specially stress on the long proboscis 

 in the female, but this is a character present in several other species, 

 among others in abbreviata, the proboscis of which is long and knee- 

 shaped, at least even as long as in Dohrni (to judge from DahPs 

 figure). Brues (Bull. Wisc. Nat. Hist. Soc. XII, 1914, 86) says that 

 Dohrniphora is heterogeneous, and he includes in it, besides a number 

 of not well recognized species, also Pseudostenophora Malloch, but I 

 quite foUow Schmitz in the opinion that Dohrniphora is a good and 

 naturally circumscribed genus, showing, however, some affmities to 

 Hypocera; it shows not few special characters as the construction 

 of the middle and hind tibiæ, the long oral bristle together with the 

 long lower postocular bristle, the single conspicuous genal bristle, 

 and the indistinct mediastinal vein. The genus has, as said above, 

 affmities to Hypocera, thus in the small to very small fork, the con- 

 struction of the hind tibiæ and several other characters; Assmuth has 

 (Tijdschr. v. Entom. LXII, 1919, 196) described a Hypocera dohrni- 

 phoridea from the Bismarck Archipelago, this species has the third 

 vein unforked, but at the same time no tergite on sixth abdominal 

 segment (only the female is known), and shows some other characters 

 belonging to Dohrniphora; Schmitz, who has studied the species, 

 says in a letter to me that he considers the species as a Dohrniphora. 

 Of the genus 9 palæarctic species are known, 6 have hitherto 

 been found in Denmark.
