ART. 4 NEW PARASITIC HYMENOPTERA GAHAN 37 



lialf the wing width; venation extending one-third the length of wing, 

 the submarginal vein very slender and placed on the margin of wing 

 (no costal cell present) ; marginal and stigmal much thicker, the 

 marginal equal to about one-third the length of submarginal, the 

 stigmal equal to one-half the marginal; liind wing petiolate at base, 

 the blade parallel-sided except at apex which is subacute; discal cili- 

 ation on basal half of blade consisting of a single row of cilia, on the 

 apical half composed of several irregular rows; the marginal cilia on 

 hind margin of blade distinctly longer than width of blade, those on 

 front margin shorter; all tibiae much longer than their femora, the 

 posterior pair nearly twice as long; tarsi slender, the fore and median 

 pairs equal in length to their tibiae, the posterior pair about two- 

 thirds as long as their tibiae. General color brownish-black, the 

 head above yellowish; antennae dark brown or blackish, the scape 

 and pedicel somewhat paler; scutellum brownish testaceous, the 

 mesoscutum also more or less brownish; all coxae and femora brown- 

 ish, the tibiae and tarsi testaceous; wings hyaline with a slight infus-

Type-locality. — York Bay, New Zealand. 



Type.— C&t. No. 29452, U.S.N.M. 



Described from two females received from J. G. Myers and said 

 to have been reared from the eggs of the cicada, Melampsalta muta 

 Fabricius. 



The specimens from which this species is described are not in per- 

 fect condition, the head being badly collapsed and the thorax and 

 abdomen more or less shriveled. Consequently it is impossible to 

 describe the species more fully. Likewise the figure, while it gives a 

 good idea of the general appearance of the insect, may not be entirely 

 accurate as to shape of head, position of ocelli, and size and shape of 

 the sclerites of the thorax and abdomen, since it was impossible to 

 make sure of these details.

HADRONOTLS ATRISCAPUS, new species 



Differs from //. robustus Brues by having the second tergite about 

 twice as broad as long and without indication of longitudinal rugae 

 except at extreme base, the third tergite much less than half as long 

 as the second. May be distinguished from ajax Girault, carinatifrons 

 Ashmead, anasae Ashmead, jioridanus Ashmead, rugosus Howard, 

 and rugiceps Ashmead by the dark scape and legs, and from the 

 remaining North American species except rugosithorax Ashmead by 

 the larger size and coarser sculpture of thorax. Agrees with the
