270 PROCEEDINGS OF THE NATIONAL MUSEUM vol.84 



H. L. Seamans. Included are specimens in the Canadian National 

 Collection, Cornell University, and the collection of Andrew R. Park, 

 Jr. I am convinced that the specimens recorded as scutellaris in 

 Smith's "Insects of New Jersey" (1910) are erroneously identified, 

 but I have not been privileged to examine them. 



13. EXETASTES IGNEIPENNIS. new species 



Plate 16, Figure 6; Plate 17, Figure 33; Plate 18, Figure 60; Plate 19, 

 Figure 72; Plate 20, Figures 86, 101 



Very distinct among the species with tliick head because of the 

 black, yellow-omamented head and thorax and bright yellowish wings 

 with smoky apices. 



Female. — Length 12 mm, antennae broken. 



Head barely twice as broad as thick, finely punctate, very densely 

 so and mat anteriorly, sparsely so and shining posteriorly; occiput 

 rather shallowly concave; temples very strongly convex, nearly as 

 long as short diameter of eye; frons slightly concave above antennae, 

 with small polished scrobes; face convex, with a deep impression on 

 each side above; sculpture coarser medially; clypeus nearly as broad 

 as face and about twice as broad as long; the weakly elevated and 

 strongly punctate basal portion much shorter than the flat, finely 

 shagreened and mat apical portion, apex strongly rounded and with 

 a shallow median emargination ; cheeks in front view short and 

 straight, their extended angle acute; malar space somewhat less than 

 half basal width of mandible; mouth much broader than face; mand- 

 ible stout, evenly curved, about three-fourths longer than broad at 

 base; junction of occipital and hypostomal carinae removed from 

 base of mandible by more than half basal width of the latter; eyes 

 rather small, moderately convex, hardly as long as width of face, 

 parallel; postocellar line slightly longer than ocellocular hne and 

 nearly twice diameter of a lateral ocellus, ocelli touching posterior 

 tangent of eyes; antenna (apices of both gone) short and rather stout, 

 slightly thicker in middle, basal joint of flagellum twice as long as 

 second, joints from tenth on as thick as or thicker than long. 



Thorax shining, finely and densely punctate; prescutum with a 

 narrow median longitudinal ridge; notauli broadly impressed discally; 

 scutellum strongly evenly convex, less densely punctate than scutum; 

 propodeum evenly convex with slight median trace of apical carina 

 and distinct pleural carinae, finely reticulate rugose; spiracles elon- 

 gate, situated shortly above pleural carinae. 



Legs stout, hind femur a little more than two-thirds as long as 

 tibia; inner hind calcarium almost exactly half as long as basitarsus; 

 tarsus stout, as long as tibia, third and fifth joints equal; claws strongly 

 pectinate.
