narrow but much elevated central area appears as a broadening 

 out of the carina separating the fovege, and has a rather large 

 pit near its posterior margin and two conspicuous punctures 

 immediately in front of it. The broad deeply depressed margin 

 of the scutellum is finely wrinkled or aciculate. Abdomen at 

 base with a dense growth of fine woolly hair, and there is also 

 a small patch of similar hair on either side of the metathorax ; 

 2d segment occupying nearly the entire surface of the abdomen, 

 abdomen rather long and pointed. Feet and antennae in one 

 specimen are entirely yellow-ferruginous, in two others the feet 

 are dark ferruginous and the antennae are black. Wings 

 hyaline, broadly and rather deeply emarginate on apical margin, 

 ciliate, heavily fringed, and the triangular radial cell open on 

 the costal margin. 



Described from three specimens from Illinois. Accessions 

 numbers, 1661, 3336, 5437. Male unknown. 



Genus EucOILA West. (Cothonaspis Hartig). 



E. 7-spinosa n. sp. 



Female. — Black; feet, mandibles, and antenna clear shining 

 rufous ; length, 3 mm. 



Head: face smooth and polished, with a puncture just be-

 punctures on vertex, just back of the ocelli. Thorax: dorsal 

 margin of collar elevated and emarginate and with a conspic- 

 uous growth of coarse yellow hairs upon either side, raesonotum

 tures. Scutellum deeply bifoveate, the elevated central area 

 with a large pit near its posterior margin, and in front of this 

 pit, near the margin on either side, are three coarse setigerous 

 punctures. The broad depressed margin of the scutellum is 

 coarsely rugose. Abdomen with a narrow girdle of rather 

 coarse short hairs, 2d segment occupying nearly the entire sur-
