onym of annulipes, but it is readily separated from that species by 

 the narrower, strongly receding temples, the usually more or less 

 blackish hind coxae, the noncarinate scutellum, and the usually 

 partly striate second tergite. 



Face broader than long to the apex of clypeus but not so short as 

 in annulipes, shining, finely punctate; temples strongly receding, 

 without a bulge or tubercle; antennae slender, usually 33 to 38 seg- 

 mented; third segment of labial palpi minute, sometimes indistinct; 

 head, viewed from above, scarcely hollowed out behind; parapsidal 

 furrows impressed, foveolate ; middle lobe of mesoscutum not prom- 

 inently elevated ; propodeum rugose, not areolated, strongly decliv- 

 ous posteriorly; mesopleural furrow finely foveolate; metapleura 

 shining, evenly punctate ; inner spur of posterie tibia or about half as 

 long as the basitarsus; areolet of fore wing triangular, petiolate, usu- 

 ally not so oblique as in annulipes; medius very weak basally; first 

 abscissa of mediella about as long as the second ; abdomen much 

 more slender than in carpocapsae; first tergite longer than broad at 

 apex, longitudinally striate, the striae usually straight and rather 

 strong; second tergite about as long as broad, and usually dehcately 

 longitudinally striate on the basal two-thirds, rest of abdomen pol- 

 ished; ovipositor sheaths at least two-thirds as long as the body. 

 Head and thorax entirely black; antennae black; palpi yellow; wings 

 very weakly dusky, sometimes practically hyaline; anterior and middle 

 legs entirely testaceous; hind legs testaceous, with their coxae usually 

 more or less blackish basally, and their tibiae usually rather broadly 

 blackish apically; the hind tarsi are usually mostly yellowish; first 

 abdominal tergite entirely black; the second nearly always more or 

 less yellowish; the third and following black. 



The above notes are based on the type of laticinctm and on the 

 following material in the National Museum : Five specimens reared 

 from Tmetocera ocellana Schiffermiiller at St. Annes, Quebec; one 

 reared from the same host, in Clarke County, Wasliington, by E. J. 

 Newcomer, under Quaintance No. 11440; another recorded as a par- 

 asite of the same host at Wallingford, Connecticut, by B. A. Porter, 

 under Quaintance No. 16628; one from Vineland, New Jersey, also 

 reared from the bud moth; and five specimens without locality data.

Type. — In the United States National Museum. 



Distinguished from all related species by the uniform, dehcately 

 granular, sculpturing of the propodeum. The four specimens of the 

 type series have the head, thorax, and abdomen uniformly testa- 

 ceous; but additional material may show some variation in this 

 respect; the legs are entirely testaceous with only the apex of hind
