behind the eyes which are large and pubescent; occipital margin 
raised, carinate; posterior orbits with a narrow groove; ocelli 
in a large triangle; vertex with a fine, but clearly impressed 
median line. Antennae 14-jointed, filiform, inserted near the cly- 
peus. Mouthparts not visible. Mesonotum about twice as broad 
as long; without parapsidal furrows but with a deep, complete, 
crenulate median furrow; inner angles of axillae not meeting, 
their edges margined by deeply crenulate grooves and their 
inner angles connected by a crenulate groove. Propodeum 
coarsely reticulated and apparently without the more prominent 
longitudinal carinae present in Dinapsis. Four anterior legs 
slender, the hind pair stout, with the femora somewhat swollen 
and the tibiae enlarged apically; tibial spurs very small; hind 
coxae very large; tarsal claws very small and slender, simple. 
Abdomen as long as the thorax, elongate oval, with seven nearly 
equal segments; claspers prominent, projecting downwards and 
curved forwards, obtusely pointed. Venter convex, the sternites 
almost as wide as the tergites. Fore wing with a small elongate 
stigma; subcostal cell broad; radial vein short, curved, leaving 
the cell widely open; basal half of cubitus present, but the 
transverse cuoiti and recurrent nervure are wanting; two 
closed discoidal cells; basal cells indistinctly separated as the 
separating vein is very weak and delicate; nervulus interstitial. 
Type: P. succinalis sp. nov. 
Prodinapsis differs ro m D.napsis most strikingly in having 
the radial cell inocmplfete, in lacking the transverse cubitus and 
in possessing two discoidal cells. Also the orbital groove is 
narrower and the axillae do not meet at their inner angles. 
Prodinapsis succinalis sp. nov. (Fig. 1). 
cf. Length 2.7 mm. Probably with the head and meso- 
notum black, the remainder of the thorax dark brown, the 
abdomen light brown and the legs piceous on the femora and 
tibiae; wings hyaline and antennae with no trace of annulation. 
Head coarsely shagreened, about one-half wider than long; 
temples two thirds as broad as the eye, occipital groove dis-
