gynochelys gen. nov. 
Similar in general appearance to Gonatopus, but with the head 
snbquadrate and front convex as in Dryinus and its allies or in 
Chelogynus. Antenna? with the first, second and third flagellar 
joints extremely elongated. Thorax distinctly bilobed as in 
Gonatopus, but with the mesonotum and scutellum differentiated 
although small. Wings present as vestiges in the form of small 
membranous pads. Meso and metapleurae distinctly separated 
by a suture. Abdomen and legs as in Gonatopus. 
The present form seems to differ quite radically from anything 
that has so far been described, and I think it worthy of generic 
rank in spite of our present very meagre knowledge of the 
Dryininae. It does not seem to be similar to any of the numerous 
and very closely allied genera recently proposed by Perkins** to 
include the forms placed by other writers in Gonatopus, Dryinus, 
Chelogynus, etc. In Perkins' table (/. <:•) it would fall into his 
genus Bukoebeleia* on account of its vestigial wings. The latter 
has, however, the ordinary thoracic structure of the winged forms, 
while in Gynochelys, the thorax is profoundly modified and 
approaches the anomalous condition seen in Gonatopus. 
GYXOCHKLYS BRAUXSI Sp. nOV. (PL. 1, FIG. 2.) 
Female. Length 5 mm. General color piceous, head black, 
legs and antennse varied with paler brown ; clypeus and mouth 
parts rufous ; mesonotum and scutellum pale rufous. Head two 
and one-half times as wide as long, the temples obliquely trun- 
cated, vertex between the eyes rounded, gently convex; front 
also convex, or when seen from above, straight. Antennse in- 
serted at the base of the clypeus, very slender, as long as the head 
and thorax together. Scape short and stout, strongly curved; 
pedicel slender, half the length of the scape ; first flagellar joint 
slender, almost twice as long as the scape and pedicel together, 
and three-fourths as long as the greatest width of the head ; 
second and third joints decreasing, the third two-thirds the length 
of the first; the apical four joints shorter and equal. Mandibles 
slender, the outer tooth very acute. Palpi short. Front micros- 
copically rugulose, with a raised median line. Ocelli small, placed 
in a small triangle, the vertex slightly margined just behind them.

* Eulccebeleia is preoccupied by Ashmead's Eukcebelea, Proc. Wash. 
Ent. Soc. VI, p. 126 (1904), a genus of Chalcidoidea ; but never having 
seen Perkins' species I would hesitate to propose another name.
