1937 ] Hymenoptera from North Carolina 133 
Therefore, the author has come to the inescapable con- 
clusion that the aforementioned genera are synonymous 
with Pseudoxenos. Altho no specimens have been examined 
of Macroxenos Schultze, 1925, from Odynerus, according to 
the description and figures this genus should also be referred 
to Pseudoxenos. 
The following is a synopsis of the genus as herein re- 
defined. 
Genus Pseudoxenos Saunders, 1872 
Eupathocera Pierce, 1908a; Ophthalmo chlus Pierce, 
1908b ; Homilops Pierce, 1908c ; Leionotoxenos Pierce, 1909a ; 
Sceliphronecthrus Pierce, 1909b ; Macroxenos Schultze, 1925. 
Male. Radius of the hind wing with the detached apical 
portion distinct and originating posterior to the main vein ; 
otherwise similar to Xenos. Metathoracic scutellum strongly 
narrowed anteriorly and with its anterior edges usually 
convergent but sometimes almost parallel. Metathoracic 
postlumbium not strongly spindle-shaped but frequently 
somewhat constricted at the middle. iEdeagus extremely 
variable according to species and apparently without generic 
significance. 
Female. Cephalothorax darker on the anterior one-half 
than on the posterior one-half. Abdomen with three genital 
tubes entering the brood canal, as contrasted with four in 
Xenos. 
First Stage Larva. Each eye composed of five ocelli, three 
dorsal, one lateral, and one ventral. Hind femur with one 
apical bristle, hind tibia with one outer bristle and three 
inner bristles, hind tarsus with a small subterminal pulvillus 
giving it a forked appearance in profile. Abdomen with six 
rows of stout bristles on sternites two to seven. Sternite 
nine bearing a pair of short stout tubercles furnished with 
long apical bristles and very short subapical ones. Tenth 
abdominal segment with a pair of latero-dorsal spines which 
are approximately half as long as the terminal stylets. 
Stylopized Hymenoptera from North Carolina 
It is interesting to note that only very rarely has the State 
of North Carolina been included as a locality in lists of
