Scolia nobilitata FABRICIUS, Systema Piezatorum, 1804, p. 244, n. 32. 
Smith in his catalogue of the British Hymenoptera, page 
206, records a Fabrician specimen in the Museum of the Lin- 
naean Society of London. 
Burmeister has recorded size for this species as 5 to 8 lines. The 
length of the specimens that the writer has had the opportunity to 
examine vary in the female from 12 to 16 mm., in the males from 8 
to 12 mm. 
In comparison with the group as a whole this is a small species. The 
body is black and there are always four yellow spots on the abdomen, 
the second and third segments each having two. In a large number of 
cases there is a ferruginous tinge to the abdomen and the yellow markings 
on the body are encroached upon by this coloring. The wings are 
uniformly fuliginous with violet reflections at some angles, blue at others. 
The nervures vary from dark ferruginous to quite black. 
Fabricius described the type as hairy and black, with two yellow 
spots on the prothorax and the scutellum yellow, base of the abdomen 
ferruginous and bearing four yellow spots. 
Head black, antenne cylindrical, thorax globose, black, prothorax 
has two yellow spots, postscutellum yellow. Abdomen hairy and 
black, the three basal segments obscurely brick red. Segments two 
and three each with two yellow spots. Legs ferruginous, femora black. 
The Insect Book by L. O. Howard (plate I, fig. 2) gives a good cut 
of a female of this species. 
The specimens that the writer has examined agree quite well with 
Fabricius’ description and also with the illustration given by Howard, 
except for slight variations. The average female has a black head 
except for the mandibles and the underside of the antenne. The man- 
dibles are ferruginous, becoming almost black toward their tips and the 
antenne though mainly black have a ferruginous tinge, particularly 
beneath. 
The thorax is black except for two yellow triangular spots on the 
pronotum, a large yellow mark on the postscutellum and the tegulze 
which are ferruginous. Coxe and trochanters black, femora partly 
black, partly ferruginous and the remaining portions of the legs ferru- 
ginous except the tips of the claws which are black, spines ferruginous. 
Wings uniformly fuliginous, with blue and violet reflections. The 
ground color of the abdomen is black but there is a tinge of ferruginous 
especially in the first three segments, more generally present in the first.
