404' Mr, Rowla^ E. Turner’s Notes on the Scoliidae. 
on the same page as septemcincta, Fabr., does not appear 
to be that species, but the description is not clear. 
The species of Dielis described by Mantero (Ann. Mus. 
Civ. Storia Nat. Genova, xl, p. 592, 1900), and Schulz 
(Berlin Ent. Zeitsch., xlix, p. 212, 1904), as D. formosa, 
Guer., from New Guinea seems also to be wrongly identi¬ 
fied, for in true formosa the second recurrent nervure is 
always complete. The shortening of that nervure is how¬ 
ever characteristic of D, subopaca, Turn., which is very 
closely allied to Discolia cnlta, Sm., from New Guinea.

This is probably the Australian subspecies of Dielis 
aurulenta, Sm., which has a wide range in the Malay 
Archipelago. Dielis agilis, Sm., from Celebes seems to 
me to be the male of aurulenta, not of lindenii as Saussure 
suggests. The sexes of the Australian form being known, 
it is unlikely that tlie male of aurulenta is very different 
to that of subopaca. In aurulenta the second recurrent 
nervure, though present, is often indistinct, in agilis it is 
well marked ; in subopaca it is incomplete in both sexes, 
and in Scolia culta, Sm., from New Guinea wholly absent 
in the only specimen I have seen. 
Scolia {Dielis) humboldti, Cam. 
Dielis humboldti, Cam., Nova Guinea, v, 1, p. 53, 1903, 
Hab. Bismarck Archipelago, Ralum. 
Females from Ralum agree well with Cameron’s de¬ 
scription. There are two male species of Dielis in the 
Berlin Museum from Ralum, one of which agrees with 
the remarks of Cameron on a male Dielis, sp. 4, 1. c. p. 53, 
which is almost certainly the male of huinboldti ; the 
other, which is probably the male of ferrugineipes, Mant., 
has the clypeus wholly yellow, also the pronotum, base of 
the scutellum, a transverse line on the postscutellum, the 
four basal abdominal segments at the apex and the outer 
side of the tibiae. The pubescence on the median seg¬ 
ment is grey in humboldti pale fulvous on the other 
male, and in the latter the first abdominal segment is 
distinctly narrower in proportion to the length. But this 
male can only be assigned to ferrugineipes with doubt,
