THE NORTH AMERICAN DIGGER WASPS OF THE 
SUBFAMILY SCOLIINAE.* 
Oscar C. BARTLETT, B. Sc. 
INTRODUCTION. 
This contribution to our knowledge of the sub-family 
Scoliinze (digger wasps) found in North America, Central 
America and the West Indies, is the result of work done at the 
Massachusetts Agricultural College under the direct supervi- 
sion of Doctor H. T. Fernald, and forms a portion of a thesis 
for the degree of doctor of philosophy. In it, an attempt has 
been made to place before those interested, a paper in which 
our present knowledge of these wasps is systematically arranged 
and the identification of the species facilitated. 
There are given here the descriptions of nineteen species and 
two genera, while four unknown species and one unidentified 
subspecies are listed at the end. Of the above mentioned 
species three are new. ‘The type of each genus has been given 
in the historical sketch and so far as is known, the location of all 
the types has been stated in each specific description. When- 
ever the writer thought it necessary, translations from the orig- 
inal descriptions or direct copies have been made. In each 
case full credit has been given to the original writer. 
Several workers have published descriptions of members of 
this subfamily in various publications and many have from one 
to several references to the group, showing the scattered char- 
acter of the information. Works which the writer has found 
most important are: Saussure and Sichel, Catalogus Spec- 
ierum Generis Scolia, 1864; Burmeister, Bemerkungen tiber 
Bau u. Gesechlechtsunterscheide Gattung Scolia, Abh. Nat. 
Gesell. Halle, 1854; Saussure, Desc. esp. nouv. Scolia, Ann.
