The typical examples of this species are described by Say in the 
Boston Journal of Natural History, Vol. I, page 363. The body is 
black; head and thorax immaculate; wings dark violet blue; cubital cells 
two, with no appearance of more than one recurrent nervure; abdomen, 
first and second segments black; remaining segments ferruginous, more 
hairy than the others; the third segment, however, more or less tinged 
with blackish and with two transversely oval, a little oblique, bright 
yellow spots. 
The specimens that the writer has personally examined agree quite 
well with the above description except that there is a strong tendency 
for variation in three directions. In one direction the specimens have 
the first two segments quite ferruginous. In another the whole abdomen 
is very black, only the edges of the segments beyond the second being 
ferruginous. In the other specimen the yellow spots gradually diminish 
until they entirely disappear. Smith in his Catalogue of Hymenopter- 
ous Insects of the British Museum describes a variety in which the yellow 
spots are obsolete. It is probable that this form without spots is the 
one that has been described by Burmeister as a separate species haema- 
todes. The writer thinks that this form should be regarded as a sub- 
species of dubia. This would cause the name dubia to become Scolia 
dubia dubia; and hematodes, Scolia dubia haematodes. 
Saussure and Sichel have recorded this species as found in 
North America; Carolina, Louisiana, Maryland, Tennessee, 
and Mexico. The writer has seen specimens from Mexico, 
Texas, Arizona, Georgia, Carolina, Virginia, Maryland, New 
York, and Massachusetts. Probably this species does not 
exist farther north than the last named state. 
The Insect Book by L. O. Howard, plate I, fig. 7, gives a 
cut of this species.

The location of the type is unknown to the writer. 
Burmeister describes the species as follows: Black, hairy, abdom- 
inal segments 3 to 6 rufous, wings nigro-cyanis. The length 7 to 8— 
1144 90 —Mexico. 
This insect looks like and is colored and haired like Scolia dubia 
except that the two yellow spots on the third abdominal segment are 
wanting. As a whole, it is much smaller than dubia. 
The writer has seen a large number of specimens that agree with this 
description except that one male specimen he has before him, has the 
sclerites of the abdomen black or slightly ferruginous and only the hairs
