The genus Scolia as originally defined by Fabricius included 
10 species. The eighth species, Scolia quadripunctata Fab., was 
chosen as the type by Latreille in 1810. No older designation 
of type for this genus is known to the writer, therefore Scolia 
quadripunctata Fab. is considered the type of the genus Scolia. 
From this it is evident that the designation of Scolia flavifrons 
as type of the genus cannot hold. 
Saussure and Sichel divided genus Scolia into the subgenera 
Triscolia and Discolia. As already stated Scolia flavifrons was 
selected by Bingham as the type and belonged to the subgenus 
Triscolia. The type Scolia quadripunctata selected by Latreille 
belongs to the subgenus Discolia however and upon raising 
these subgenera to generic rank, Discolia becomes a synonym 
of Scolia while Triscolia, regarded by Ashmead as a synonym 
of Scolia because flavifrons which he selected for the type 
belonged in that section, necessarily is restored from a synonym 
to a valid genus. Triscolia was established by Saussure and 
Sichel and under it were placed twenty-five species, none of 
which was designated as the type. So far as the writer has 
observed the only species of this list which has been designated 
as the type since, is Scolia flavifrons Fab. which was done by 
Bingham as already indicated. Accordingly therefore the 
subfamily Scoliinz may be considered so far as North America 
forms are concerned, as including the genus Scolia with Scola 
guadripunctata Fab. as its type, and the genus Triscolia. As 
the latter had the species flavifrons designated as its type when 
it was supposed that it was a synonym of Scolia, it would seem 
desirable to retain this same species as the type now that it 
has become an established genus. Scolia flavifrons Fab. is 
therefore here designated as the type of the genus Triscolia, 
no earlier designation for this genus having been observed. 
The above is the history of this group that the writer wishes 
to adhere to, yet Schrottky in the Deutsch Ent. Zeitschr 1910, 
Heft II, page 196 says that Triscolia of Saussure and Sichel 
should become Ascoli of Guerin. In tracing Ascoli back to the 
reference, (Guerin, Duperry: Voy. Coquille. Zool. II, 1830, 
page 247,) I find it indeed true that this is the first reference to 
the insects included in the group Triscolia, that is so far as can
