" This group is not proposed as a Natural Family, and therefore 

 is not designated by a name conformable. Two genera of doubt- 

 ful affinity are temporarily associated in it, by the artificial charac- 

 ter above given, to avoid the multiplication of families, until their 

 true respective places are better demonstrated. The first of these 

 [Orphtiepliila) has indeed already been proposed by Ilondani,"^' 

 as the type of a distinct family, Orj^hiephllina, intercalated between 

 the Bibionina and SciojjhiluKe. Macquart, with confessed hesita- 

 tion, has placed the genus among the Fungicolce (= Mi/cetophUi- 

 dce), Zetterstedt among his /i?//yj'V^ii ; Haliday, the first describer,t 

 referred it to the group CnUciformes (= Culicidce — Chironomi- 

 (Im), but expresses himself still unsatisfied as to its proper place, 

 after examination of the internal anatomy. The metamorphosis, 

 which would throw more light on the question, has not yet been

t Agassiz has given the dales, 1830 for Orphiephila, Hal., and 1832 for Tliau- 

 maUa, Rulhe; bnt in fact Orphtiephila was not published before the 1st of Septem- 

 ber, 1831, in the I'Jth number of the ' Zoological Journal '; while lluthc's characters 

 of T/ianmalea ap])carcd iu the number of the 'Isis' for the November of the same year. 

 As Wagler had employed the latter name, almost contemporaneously, for a geuus of 

 birds, the priority of the former is here recognized, liut as the names date from the 

 same year, and as Macquart at a later period casually chose the same trivial name as 

 1{ utile's testacea, this has been retaiucd iu prefercuce to the strictly prior uame 

 devia.
