166 NEW CHALCID PARASITES FROM MALAYA. 



Genus RHYNCHENTEDON novum. 



(Entedonini). 



Head from in front twice wider than long but the mouth pro- 

 duced into a short cone, the eye forming the lateral boundary, the 

 antennae inserted below middle of. face (at base of the snout)', the 

 latter with a wide V-shaped suture across about middle, meeting 

 a similar median suture from between the antennae up ; face rough- 

 ly shagreened, more roughly dorsal of the suture. Marginal twice 

 the submarginal, stigmal minute, postmarginal elongate. Para- 

 psidal furrows over half complete. Abdomen conical, longer than 

 the rest of the body, 2 half surface, others short, petiole upon 2 

 so that the abdomen projects beneath it, half longer than wide, 

 thick, curved. Propodeum with a short neck, two separated median 

 carinae which swell at basal half (that is to say are twice farther 

 apart along about basal half, since each cohvexes from base and 

 then at distal half becomes straight and parallel to the other) ; 

 they diverge widely at the neck; a straight lateral carina. Anten- 

 nae 9-jointed with three wing joints (2 and 3 very short), club 

 solid, nippled. Mandibles short rounded at apex, dentate. Hind 

 tibial spur stout. Cephalic tibial spur short, forked. Scutum, 

 scutellum simple. A " valley " lateracl of lateral carina of pro- 

 podeum. 



Rhynchentedon maximus sp. nov. 

 Geno type. 



Three mm. Aeneous, wings with a large oval spot from 

 proximal side of stigmal vein extending three-fourths wav 

 across. Legs and scape red, knees, tarsi and tibial tips white. 

 Funicle 1 elongate, longer than the scape, twice 3 ; 2 equal 

 to club which is shorter than scape ; 3 twice longer than wide, 

 shortest save the very short pedicel. Thorax rather coarsely 

 punctate; propodeum laterad of lateral carina, its neck (a 

 part beyond the diverged ends of the median carinae which is 

 tricarinate) and abdomen densely scaly; petiole with carinated 

 sides and at base a weak pair of median carinae. Propodeum 

 glabrous between lateral carinae. 



Singapore, C. F. Baker, one female. 

 Genus LUTHERIA noA T um. 

 (Encyrtidae). 

 Frons glabrous with scattered setigerous pin-punctures, lower 

 face scaly with these punctures thick, the scrobes very short, in a 

 semicircular depression bounded by the acute edges of the frons. 

 Euns to Baocmusia but club solid and only one-fourth longer than 

 funicle, marginal vein punctiform, the venation reaching costa 

 only at apex of marginal which is well developed, two-thirds the 

 straight stigmal; mandibles with two equal, acute teeth which are 

 short and wide ; frons moderate ; f unicles not subannular but much 

 wider than long; ovipositor issuing at apex. Robust. Abdomen 

 depressed rotund.
