Observations. Described from a single & specimen taken at 
Philadelphia. Similar to P. urbanus, Brues, but smaller and 
distinguished by the dense abdominal pubescence. 
Type in the National Museum. 
Pezomachus auripes sp. nov. 
Male, length 3.5-4 mm., wingless. Shining black, with bright 
yellow legs. 
Head from above rectangular, not transverse; occiput but slightly 
excavated, ocelli small. Antenne about 21-jointed, piceous black, 
seventh and neighboring flagellar joints about twice as long as thick. 
Face shining black, closely and evenly shagreened, with a short whitish 
pubescence. Mandibles and palpi testaceous; malar line obsolete, about 
one-third as long as the face is wide. 
Thorax finely and evenly shagreened, with a moderately sparse 
short pubescence; scutellum well defined, flat dorsally; tegulz yellowish 
white. ‘‘Metathorax”’ with a well defined carina. Legs long and slen- 
der, bright yellow including the coxe. Tarsi rather more dusky. 
Abdominal petiole short, closely and finely shagreened, with an even 
sparse pubescence. Spiracular tubercles absent. Remainder of abdomen 
shining, finely shagreened, sparsely pubescent, elongate oval, terminating 
with two much enlarged piceous black claspers. 
Observations. Described from a single damaged specimen 
takenvat St. Pauls Island, Alaska, by 1. Kincaid (Harriman 
Expedition). 
This is a very pretty and distinctive species; it much resem- 
bles Ashmead’s description of P. obesus @ (Proc. Wash. Acad. 
‘Sci. Vol. 4, p. 192) drawn up from a female specimen taken in 
the same locality, and it seems probable that it will be found to 
be the male of this species. 
Type in the National Museum.

-abdomen piceous with ferruginous petiole and similarly colored apical 
band on the second segment. 
Head rather large, from above somewhat quadrate, finely shagreened 
with a short sparse pubescence, uniformly ferruginous, about twice as 
wide as thick along the median line. Antenne long and slender, about 
25-jointed. Pedicel and first two or three flagellar joints ferruginous, 
remaining joints piceous black. Malar line indistinct, short, about 
one-third as long as the face is wide at the lower angles of the eyes, eye
