108 MISCELLANEOUS FOEEST INSECTS. 



MARLATTIA Ashmead. 



Marlattia Ashmead, Can. Ent., vol. 30, p. 287, 1898. 



Type. — Hemicliroa laricis Marlatt. 



Clypeus shallowly emarginate; malar space present; pentagonal area present; 

 antennae slender, filiform, fourth joint longer than tVie third; thorax normal for the 

 group; legs normal except for the simple tarsal claws; venation normal except the 

 intercostal vein, which is interstitial with the basal, and the third cubital cell, which is 

 short as in Pteronus. 



Easily known from Hemichroa by the simple tarsal claws. 



OPISTHONEURA Aslimead=ZASCHIZONYX Ashmead. 



The type of Opisihoneura crevecoeuri Ashmead is the same as Hop- 

 locampa montana Cresson, which is the type of Zaschizonyx Ashmead.

PARAZARCA Ashmead. 



Parazarca Ashmead, in Dyar, Journ. N. Y. Ent. Soc, p. 128, 1898; Can. 



Ent., p. 252, October, 1898. (Type, Parazarca fuinipennis Ashmead.) 

 Calozarca Ashmead, in Dyar, Journ. N. Y. Ent. Soc, p. 129, 1898; Can. Ent., 

 p. 252, October, 1898. (Type, Selandria fascipennis Norton.) 

 Eyes large, subparallel or slightly converging to clypeus; malar space very narrow 

 so as to be nearly wanting; clypeus truncate, rather large as is the labrum; lateral 

 ocelli below the supraorbital line, the posterior orbits therefore rather narrow; antennae 

 hairy, pedicellum much longer than wide, third joint the longest, apical joints short 

 and narrowing apically; mesosternum with a distinct, triangular-shaped praesternum; 

 mesopleurge without a suture separating off a prepectus, metanotum with a distinct 

 "scutellum;" tarsal claws with a large inner tooth appearing cleft, also a small post- 

 basal tooth, basitarsis subequal with the following joints; wings of the normal blenno- 

 campid type; transverse median in the middle of first discoidal cell; third cubital 

 cell longer on the radius than the first and third combined; radial cell of the hind 

 wings appendiculate; no closed discal cell in the hind wings and the anal cell distinctly 

 petiolate. 



PARAZARCA FITMIPENNIS Ashmead. 



Parazarca fumipennis Ashmead, through Dyar, Journ. N. Y. Ent. Soc, p. 128, 

 1898. 



Female. — Length, 7 mm. Lateral angles of the clypeus rounded; frontal fovese 

 broad, shallow, the lateral ones somewhat circular in outline; the middle fovea joining 

 with the ocellar basin and forming a broad, shallow, depressed area; antennal furrows 

 obsolete; postocellar furrow faintly indicated; lateral boundaries of the postocellar 

 area sharply defined; postocellar line a very little shorter than the ocelloccipital line; 

 stigma broadest at base, tapering gradually to the apex; second recurrent vein quite 

 free from the second transverse cubitus; sheath very robust, straight above, the apex 

 truncate, the oblique lower part emarginate; saw obliquely ribbed, the teeth small; 

 sharp, and regular. Shining reddish yellow; flagellum, spot inclosing ocelli, apex of 

 saw, and four posterior legs below middle of tibiaj black; anterior tarsi brownish, 

 wings brown, venation brownish black. 



Male. — Length, 6 mm. Almost exactly as in female. Hypopygidium one and 

 one-fourth times as long as wide, the apex gently rounded.
