1912] North American Scoliine 327 
The typical examples are described by Saussure as follows: The 
female on the average of a deep black, shining, with black hair. Head 
‘and thorax very finely punctured; the metathorax deeper than the rest, 
abdomen irregularly punctured, wings deep black with bluish or steely 
reflections. The nervures are black. Males are very densely punc- 
tured. 
The specimens that the writer has studied agree with this descrip- 
tion except that the wings held at some angles have a greenish reflection 
as well as the bluish and purplish reflections spoken of above. At the 
point where the second ventral segment of the abdomen bends abruptly 
upward to meet the first ventral segment and on either side of the 
midline on the body is a bluntly rounded tubercle quite large in some 
specimens especially in the male, smaller and almost disappearing in 
some of the females. 
Saussure and Sichel in their catalogue give the habitat of 
the species as Mexico. All specimens that the writer has seen 
came from Mexico. 
So far as structure goes the writer has been unable to sepa- 
rate this species from gutiata Burmeister. He is of the opinion 
that aside from the color they cannot be separated and for this 
reason he would consider this form a subspecies of guttata. See 
what already has been said on this subject under guttata.

Scolia imconstans Cress., Proc. Ent. Soc. Phila., 1V, 1865, p. 446, No. 2. 
The type is in the collection of the American Entomological 
Society at Philadelphia. 
Cresson describes the species as follows: 
Scolia inconstans, n. sp. 
“Obscure ferruginous; head, antennee and most of thorax blackish; 
sides of prothorax with a large luteous spot; third segment of abdomen 
with a yellow spot; wings subhyaline, the costa yellowish, with a dark 
streak beyond the marginal cell. 
‘““Male.—Head black, with yellowish pubescence; the orbits, more 
or less interrupted, yellowish; anterior margin of the clypeus, and the 
mandibles, except tips, luteous; antennz nearly as long as the head and 
thorax, dull black, somewhat brownish beneath. Thorax blackish, 
with rather dense, prostrate, yellowish pubescence, and close, rather 
deep punctures; on each side of the prothorax a large luteous spot; 
lateral margins of the mesothorax obscure testaceous; pleura sometimes 
with a ferruginous stain; postscutellum luteous, and sometimes the 
scutellum is tinged with the same color; metathorax black, sometimes 
rufo-piceous, on each side a large rufous or ferruginous spot or stain,
