Description of a New Proctotrupid. 



By William H. Ashmead. 

 Jacksonville, Florida. 



Since the publication of my "Studies on the N. A. Proctotrupidae," 

 in going over my Braconids, two specimens of a very remarkable form in 

 this family were discovered belonging to a genus not yet noticed as oc- 

 curring in the North American fauna. The genus is recognized by the 

 brevity of the otherwise fully developed wings, the elongated prothorax 

 and its rather prominent eyes and triangular head. The species may be 

 identified from the following description : 



VII. MYSTROPHORUS, Foerster. 



i. Mystrophorus americanus, n. sp. O. Length .25 inch. Color: Head, 

 thorax and legs, brownish-red ; head above dusky ; eyes dark or blackish ; antennae 

 dusky toward tips, while the abdomen is polished black. The head when viewed 

 from the front is triangular, finely, regularly punctate. The antennae are 10-jointed, 

 the third joint of which is as long as the 4th, 5th and 6th joints together. The pro- 

 thorax is much elongated with parallel sides, narrower anil more than thrice longer 

 than the mesothorax, and microscopically sculptured. The short, spoon-shaped 

 wings are hyaline, excepting a broad, smoky, transverse band across fore wings, 

 broad enough to include stigma and stigmal vein. The venation is exactly as in the 

 genus Goniezus. •
