1912]: The Pezomachini of North America 135 
Thorax narrow, ferruginous, closely and evenly shagreened, sparse 
minute pubescence. Mesothorax rather strongly margined, with a 
broad shallow median furrow. Scutellum tuberculate. Tegule white. 
““Metathoracic”’ carina angular, (i. e., not semi-circular or sinuous) well 
-defined at the sides, but less distinct medially. Legs rather more dusky- 
ferruginous than the thorax, especially dark on the hind tibiz. 
Abdominal petiole short and broad, typically ferruginous, but 
-dusky in some specimens, as a rule without prominent spiracles, these 
however, may be placed on small projections, surface shagreened and 
‘sparsely pubescent. Remainder of abdomen narrow oval, piceous 
black except for a ferruginous apical band on the second segment; 
surface finely shagreened and with a sparse pubescence. Claspers 
piceous, rather small. 
Observations. Described from six specimens bred from spi- 
ders nests taken in Connecticut (Linn, New Haven and Ridge- 
field) and from three specimens bred from a single nest taken in 
Pennsylvania (N. Cumberland). 
Although these specimens were never actually bred out 
‘from the same nests as @ ottawensis (Harrington) they were 
bred from nests taken from the same places as nests yielding 
‘specimens of the named female, and owing to their striking 
similarity in color and petiolar form there can be no doubt that 
they represent the o& of this species. 
The specimens from which these were described have been 
-sent to the State Entomologist, New Haven, Connecticut. 
A winged specimen has been reported‘ as the male of this 
species but no complete description was drawn up. The only 
data given was in the specific tables where the following identi- 
fication characters were given, ‘‘Winged’”’. ‘‘Black with seg- 
ments two and three of abdomen yellowish’’. It would seem 
‘that this correlation was incorrect since such a male must be 
very unlike the 9. The origin of this report cannot, unfor- 
‘tunately, be traced. 
Pezomachus ashmeadii nom. nov. 
Cremnodes californicus Ashm. 
The female of this species, described by Ashmead as Crem- 
nodes californicus, Proc. Nat. Mus. Wash. Vol. XII, p. 420 (1889) 
‘is entirely wingless, and has no scutellum. Since Forster in his 
‘original description of the genus Cremnodes states ‘‘ Der 
Mitelleib mit Flugelrudimenten und abgesetztem Schildchen....’’ 
this species must be removed to the genus Pezomachus in which 
the specific name “‘californicus”’ is preoccupied.
