Type.—The type of pallipes is apparently in the Melbourne 
Museum, that of barbiger is in the Academy of Sciences of Brussels, 
that of mellipes i in the Academy of Sciences of Philadelphia, and that 
of punctatus in the Provincial Museum at Quebec. 
The writer has studied the types of barbiger, mellipes, and punctatus, 
but has not seen that of pallipes. European workers are apparently 
correct in treating barbiger as a synonym of pallipes. The original 
descriptions seem to apply to the same species; and Kuropean spec- 
imens in the collection of the United States National Museum, deter- 
mined as pallipes by Marshall and Schmiedeknecht, and as barbiger 
by Walker, are identical and agree exactly with the writer’s notes on 
the types of barbiger. Furthermore, the types of the American 
mellipes and punctatus appear not only to be conspecific but to agree 
also with the type of the European barbiger. There seems to be no 
reasonable doubt, therefore, that all four names were applied to the 
same species; pallipes, being the oldest, is the valid name. 
This species is very similar to levifrons, but apparently can be 
distinguished without difficulty by means of the characters given in 
the key. Except as follows the foregoing description of levifrons 
will apply to pallipes: 
Malar space as long as basal width of mandible; frons punctate, with a median 
longitudinal carina below; occipital carina complete; antennae with 20 to 27 
segments; middle lobe of mesoscutum more or less punctate; notauli distinctly 
foveolate; impression at base of scutellum with several longitudinal carinae; 
side of pronotum more completely rugulose; mesopleurum mostly rugulose; first 
abdominal tergite rugulose striate. Clypeus varying from yellowish ferruginous 
to black; face often somewhat tinged with rufous; abdomen beyond first tergite 
usually piceous. 
The North American material examined, comprising about 125 
specimens, indicates a range in distribution from eastern Canada to 
Alabama, and from New York State westward through the northern 
half of the United States to Oregon; a singie specimen from Alaska 
is also included. Reliable host records appear to be Jacking except 
perbaps in the case of a single specimen from Idaho, which is recorded 
as having been reared from Lygus sp. by W. E. Shull: another spec- 
imen, from Geneva, N. Y., is labeled “Ex Polydrusus impressifrons?, ‘ 
but this record is probably erroneous. 
GENERA OF EUPHORINAE THAT HAVE NOT BEEN RECOGNIZED 
LOXOCEPHALUS Foerster 
Loxocephalus Foerster, Verhandl. Naturh. Ver. Preuss. Rheinlands 19 (N. F. 9): 
252, 1862. (Genotype, Loxocephalus longipes Foerster.) 
In the Foerster collection at the Zoological Museum, Berlin, the 
writer found a single specimen labeled “Loxocephalus longipes” in 
Foerster’s hand. However, it is apparently not the specimen upon
