ON THE TRIBE DEJEANIINI OF THE MUSCOID FAMILY 

 HYSTRICIIDiE, WITH FIVE NEW GENERA. 



By Charles H. T. Townsend, 

 Director of Entomological Stations, Lima, Peru. 



The Dejeaniine flies are among the most striking and interesting 

 of the muscoid group. They are characterized not only by a 

 general strong macrochsetal development showing in more or less 

 densely placed spines on the abdomen and scutellum, which they 

 share with many other forms of the Hystriciidoe, but also by the 

 unique development of the palpi which are greatly elongated. 



The tribe as so far known to the writer divides naturally into 

 the four subtribes Dejeaniina, Paradejeaniina, Lasiopalpina and 

 Dejeaniopina, the last three being monotypic. Only the last two 

 have pilose eyes. The Dejeaniina divide into three group-units, 

 the Dejeaniice with discal spines on intermediate abdominal seg- 

 ments and normal palpi, the Eulasiopalpice without discal spines 

 and with ciliate palpi, and the Eudejeaniice without discal spines 

 and with normal palpi. Dejeania was founded by Robineau Des- 

 voidy in 1830, who included therein at the time the two species 

 brasiliensis RD. and capensis RD., but without designating either 

 as the type. In 1910 Coquillett designated the latter, which equals 

 Stomoxys bombylans F., as type of the genus. Lasiopalpus was 

 founded by Macquart in 1847, with the single species flavitarsis 

 Mcq. which is thus the type. Eudejeania was founded by the writer 

 in 1912, with designation of subalpina T. as type. 



All the Dejeaniine flies known up to twenty years ago, other 

 than Lasiopalpus, were grouped under the single genus Dejeania. 

 Brauer and von Bergenstamm were the first to cut any of the forms 

 loose from this combination, characterizing the genus Parade- 

 jeania in 1893 for Dejeania rutilioides Jaennicke and Jurinia 

 myrrhea Say, BB. As the latter is a momen nudum, the former 

 stands as the type of the genus. In 1898 Brauer added to the 

 genus, Jurinia hystrix Riley (nee F., nee Will.) MS from North 

 America, Jurinia amethystina Macquart from Brazil (Minas- 

 Gerae's), Jurinia bicolor Macquart (nee Wd.) from Colombia and 

 Cayenne (two species, probably MS in coll.), Jurinia nigricalyp-
