punctate and polished; propodeum coarsely reticulately rugose; 

 propleura only weakly sculptured, largely smooth and shining; 

 mesopleura mostly smooth and shining, with the longitudinal 

 impression narrowly weakly rugulose, distinctly less strongly and 

 less extensively so than in datanae; fore wing with radius arising 

 considerably beyond middle of stigma, its first abscissa much shorter 

 than the second but usually more than half as long; recurrent vein 

 practically interstitial with first intercubitus ; posterior coxae finely 

 granular; abdomen strongly petiolate; the petiole smooth and pol- 

 ished; the postpetiole finely striate; remainder of dorsum of abdo- 

 men smooth and highly polished; ovipositor sheaths a little more 

 than half the length of the abdomen. Ferrugino-testaceous ; an- 

 tennae brownish yellow; propodeum sometimes a little infuscated 

 basally ; wings hyaline ; stigma pale yellow ; all legs entirely yellow, 

 the posterior tibiae not at all marked with black; postpetiole some- 

 times more or less blackish, but usually yellow like remainder of 

 abdomen. 



Male. — Like the female, except that there are often pronounced 

 fuscous markings on the mesonotal lobes, and the propodeum and 

 postpetiole are usually darker; sometimes apex of abdomen is more 

 or less brownish. 



Type.—CBi. No. 28053, U.S.N.M. 



Type-locality. — Sherborn, Mass. 



Host. — Cingilia catenaria Drury. The Meteorus is a solitary 

 parasite of the larva of this geometrid, only one developing upon a 

 host. 



Described from 6 females and 6 males reared in August, 1923, 

 from the above-named host, by J. V. Schaflfner, jr., under Gipsy 

 Moth Laboratory No. 12418 J 2>-a. Several other series of specimens, 

 not included in the type material, have been reared from the same 

 host, from Westerly, E. L, and Sherborn, Brewster, and Sudbury, 

 Mass., under Gipsy Moth Laboratories Nos. 12418 E 1, 12418 G 1, 

 12418 H 1-a, 12418 H 3, 12418 J 2, 12418 J 3 and 12418 K 1.
