and sciitelliim punctate; tegulae brown; wings hyaline, veins and 

 stigma brown, the latter pale at base; coxae, the base of fore and 

 middle femora, and posterior femora almost entirely, blackish; 

 abdomen black, smooth, shining; the first tergite slender, and nar- 

 rowest at apex. 



Cocoon. — " Pale grayish-brown, oblong, cylindrical, woolly, 4 mm. 

 in length." 



I have seen no specimens of this species. The above notes are 

 taken from the original description. 



22. MICRGPLITIS QUINTILIS Viereck. 



Microplitis quintilis Viereck, Bull. 22, Conn. State Geol. and Nat. Hist. 

 Survey, 1917 (1916), p. 204. 



Type. — In the Connecticut Agricultural Experiment Station, in 

 New Haven, Comiecticut. 



Very similar to feltiae, but has scutellum less coarsely roughened ; 

 the tegulae are brown ; and the first tergite does not narrow so gradu- 

 ally posteriorly. Vertex and temples closely punctate and dull ; me- 

 soscutum very dull, and closely punctate in the region where parap- 

 sidal grooves would be if present; wings very slightl}^ fuliginous; 

 radius no longer than first intercubitus ; stigma wholly brown, with- 

 out a pale spot at base; all coxae and basal trochanters black; apex 

 of posterior femora and tibiae, and the posterior tarsi dusky ; abdo- 

 men shorter than thorax; first dorsal abdominal plate slender, nar- 

 rowing abruptly near apex ; this plate is very minutely striate at the 

 sides ; remainder of abdomen smooth and shining ; venter of abdomen, 

 as Avell as the dorsum, black. 



Known only from the unique male type, from which the above notes 

 were made. 



23. MICROGASTER FELTIAE, new species. 



Related to plutellae, but is at once distinguished by its somewhat 

 larger size, by the paler legs and tegulae, and the slightly infumated 

 wings. 



Male. — Length, 2.8 mm. Face, vertex, temples and cheeks strongly 

 closely punctate and opaque ; antennae longer than the body ; meso- 

 scutum confluently punctate and opaque, without parapsidal grooves ; 

 scutellum with separate, distinct punctures, rather flat ; mesopleurae 

 coarsely confluently punctate anteriorly and below the longitudinal 

 crenulate furrow, smooth and polished above it ; propodeum coarsely 

 rugoso-reticulate, with a prominent median longitudinal carina; 

 stigma a little longer than metacarpus ; radius hardly as long as first 

 intercubitus, and strongly directed outward ; legs slender ; inner spur 

 of posterior tibiae a little longer than the outer, but less than half as 

 long as the metatarsus ; abdomen shorter than the thorax, ovate, de-
