1922 ] Brues — The Genus Pedinomma in North America 
Pedinomma 1 near cti cum sp. nov. 
<N Length 4-4.3 mm. Fulvo-ferruginous; flagellum, palpi, 
legs beyond femora and the adbominal segments beyond the 
middle of the second, lighter; first and basal half of second 
abdominal segments and teeth of mandibles darker, more or less 
tuscous. Head and thorax, except as noted, subopaque finely, 
granular. Head seen from above one-half longer than broad, its 
sides parallel behind the eyes, the centers of which are at the 
anterior third of the head; narrowed obliquely in front of the 
eyes so that the short antennal prominence is one-third as wide 
as the vertex. In profile the head is an almost equilateral 
triangle gently convex above and below. Eyes ovoid, placed 
near the top of the head, broadest in front, separated by a little 
more than their length from the base of the antennae and as 
broad as the thickness of the scape. Maxillary palpi short, 3- 
jointed; first joint very short; second broad, enlarged at apex; 
third slender, pointed, nearly as long as the second; labial palpi 
2-jointed, short. Mandibles broad, with four subequal teeth, 
clypeus clearty separated, one-third as long as the face, with 
large lateral fovese. Antennae 10-jointed; scape as long as the 
head, as long as the four following joints; second twice as long as 
thick and two-thirds as long as the third which is two 
and one-half times as long as broad; following gradually more 
attenuate, but not perceptibly shorter; last (the tenth) one- 
fourth longer than the ninth. Ocelli entirely absent. Thorax 
three times as long as broad above where it is barely as wide as the 
head; widened below, especially in front so that the pleurse 
are visible from above; dorsal surface almost flat above; 
pronotum as long as the propodcum, but the mesonotum and 
scutellum together about half as long as either of the others; 
prothorax with a distinct constriction near the anterior edge 
extending from the lateral edge entirely across the middle; 
anterior to this it is indistinctly transversely aciculate. Mesono- 
tum very small, in front two-thirds as wide as the pronotum, and 
narrowed behind, with the lateral edge raised and preceded by a 
iWestwood applied the name Myrmecomorphus to.’his species, but Forster considered this 
as! a homonym of Dulour’s dipterous genus Myrmemorpha since the latter word is incorrectly 
formed. Later authors have used Forster’s name Pedinomma and I have here followed them
