1909] American species of Scolioneurinae 267 



longer than the fourth and not as long as the fourth and fifth together, 

 the eighth and ninth subequal; the wings hyaline, the venation pale 

 brown; the front wings with the radio-medial cross-vein represented 

 only by minute rudiments; the free part of M^-I-Cui received in the 

 cell M4 distinctly beyond its middle; the stigma twice as long as wide, 

 angled at middle and at the point of attachment of the radial cross- 

 vein; the hind wings with the cell Rj+j closed and appendiculate at 

 apex; the saw-guides straight above, obliquely truncate, and rounded 

 below. Length 3.5 mm. 



Habitat. — Brooklyn, New York. Type in the collections of 

 the American Entomological Society. 



Described from notes made by Mr. S. A. Rohwer for the 

 writer from the type. 



The present synopsis was prepared for publication several 

 months ago, it was not sent off because of the uncertainty felt as 

 to the status of the species canadensis , capitalis, and rubi. My 

 views regarding the validity of these species based on the data 

 and specimens at hand were written up ready for publication 

 and the description and notes were loaned to Prof. C. O. 

 Houghton* and included bv him in an article on "The Black- 

 berry Leaf-Miner." The description there given is based in 

 great part on the specimen described in this paper as Metallus 

 rohweri. The careful study made of the types of canadensis 

 and capitalis by Mr. Rohwer, together with the accumulation of 

 several additional specimens has convinced me that I was in 

 error and that all these forms should be ranked as distinct species. 



Metallus rohweri n. sp. 



Body black with the two basal segments of the antennae more or 

 less, the middle and lateral lobes of the mesonotum, the scutellum, 

 and its appendage, and the postscutellum, rufous; the legs with the 

 trochanters, the knees, the front and middle tibiae and tarsi, the post- 

 terior tibiae, more or less infuscated toward the apex, and the posterior 

 tarsi yellowish-white ; the antennal furrows extending a short distance 

 from the antennal fovea, interrupted and forming a deep well-like 

 puncture, interrupted on the middle of the front to opposite the 

 median ocellus, continued around the outer side of the lateral ocellus 

 to the occiput, the vertical portion of the antennal furrows punctiform, 

 longer than wide ; the interocellar furrow deep and straight ; the post- 

 ocular area strongly convex and distinct; the ocellar basin elevated, 

 flat, forming an indistinct pentagonal area, depressed in front of the 

 median ocellus and a square depressed area behind connecting with 

 the interocellar furrow; the supraclypeal area not strongly elevated, 

 uniformly convex; the median fovea broad, deep, and prominent
