1912} The Pezomachini of North America 119 
Pezomachus brevistylus sp. nov. 
Female. Length 3.5 mm., ferruginous, with apical half of the 
abdomen piceous; short and robust with a much abbreviated ovipositor; 
entire body rather densely pubescent. 
Head from above ferruginous, finely shagreened and pubescent, 
about twice as wide as thick along the median line. Antenne short and 
stout, 19-jointed; scape and first few flagellar joints ferruginous, remain- 
der piceous, seventh and neighboring flagellar joints not quite twice as 
long as thick. Face below antennz somewhat swollen, subtuberculate, 
clypeus semi-circular, indefinitely separated basally; malar lines distinct, 
about 1-3 as long as the face is wide at the lower angles of the eyes. 
Mandibles yellowish. 
Thorax distinctly bi-nodose, ferruginous with a short rather dense 
pubescence. Scutellum hardly indicated, mesothoracic tegulae small 
but prominent; “‘metathoracic”’ carina poorly defined medially but 
prominent laterally. Legs ferruginous, hind legs infuscated at apex of 
the femora and over most of the tibie. 
Abdominal petiole short and broad, spiracles moderately prominent, 
surface ferruginous and shagreened; with a fine short pubescence; 
remainder of the abdomen short oval, second segment ferruginous, 
following segments piceous, surface punctulate, entirely clothed with a 
dense short pubescence. Ovipositor very short, about one-third the 
length of the short petiole; sheaths piceous. 
Observations. Described from a single specimen taken at 
Philadelphia. Closely related to P. ashmeadiw (Cremnodes 
californicus Ashm.), but readily distinguished by its color and 
more definite carina. Both of these species fall into a very 
distinctive group of Pezomachini the most distinctive characters 
of which are the shortened robust form of the body together 
with the much abbreviated ovipositor, and it is possible that 
these characters will be found to be of sub-generic value. 
Pezomachus minutus sp. nov. 
Female. Length 15 mm. Entirely piceous black, petiole short and 
broad at the apex. Ovipositor short. 
Head transverse, temples swollen, about 21% times as wide as thick 
along the median line. Surface polished though very finely punctured. 
Face below antennz more coarsely punctured and hairy, produced 
forward immediately below the insertion of the antennz, so that the 
latter are placed on a small horizontal ledge. Malar line distinct, about 
one-third the width of the face. Clypeus poorly defined, transverse. 
Mandibles and palpi piceous, concolorous with remainder of the face. 
Antennz sub-clavate, piceous, entirely pilose, 17-jointed, reach to apex 
of petiole. Seventh and neighboring flagellar joints about 114 times as 
long as wide.
