ENCYRTINI. 



Encyrtus barbatus n. sp. 



Very closely allied to bicolor (Howard) and similar struct- 

 urally except as follows: Face in the female distinctly trans- 

 versely lineolate, the beard on the cheeks considerably longer 

 and more conspicuous, the bristles on the sides of the abdomen 

 and towards the apex somewhat longer and more prominent. 



Female: Head shaped as in bicolor (Howard), infelix (Embleton) 

 and allied species ; the transverse carina separating the frons and face 

 extending outward to the lower corners of the eyes, the middle portion 

 of the median indentation of this carina curved slightly downward to- 

 wards the mouth ; the longitudinal carina on the cheeks and postorbital 

 region, very distinct and extending considerably in front of the eyes; 

 carina connecting the posterior ocelli straight or slightly arcuate ; anten- 

 nae, thorax, wings, legs and abdomen as in allied species. 



Frontovertex finely, transvrsely lineolate with distinct, scatte-ed and 

 remote punctures ; face more coarsely, transversely rugoso-lineolate and 

 more or less reticulate on the median part, but becoming smoothish above 

 within the indentation of the transverse carina ; thorax finely granular 

 alutaceous, with the propodeum smooth and polished except at the sides ; 

 the pro- and metapleura and abdomen delicately reticulate ; the meso- 

 pleura microscopically reticulate or appearing smooth and polished under 

 moderate magnification. 



Trontovertex with a fine whitish scattered pubescence arising from 

 the punctures, the face with a similar pubescence ; cheeks with a beard 

 of long, black, bristle-like hair, apex of clypeus and base of mandibles 

 with somewhat shorter black hairs, posterior margin of the pronotum, 

 and the mesoscutum rather densely covered with recumbent black hair 

 changing to white on the posterior half of the scutum ; axillae and 

 tegulae with moderately long, black, bristle-like hair ; base of the scu- 

 tellum with a fine, soft, whitish pubescence with a few much longer pale- 

 colored hairs in front of the apical black fascicle ; sides of the abdomen 

 with several very long black hairs besides the vibrissae, the apex with 

 shorter whitish hair. 



Length: 1.67 to 2.13 mm. 



Head nearly raw* sienna (Ridgway) but more or less infuscated espe- 

 cially on the frontovertex which becomes brownish to quite fuscous, the 

 cheeks on and just below the carina black; pleura of thorax nearly pure 

 raw sienna, always clearer yellowish than the head ; notum of thorax 

 about ochraceous orange (Ridgway) with the posterior margin of the 

 pronotum, usually the anterior margin of the scutum, posterior half or 

 more of the scutum and declivous portion of the axillae black, the basal 

 margin of the scutellum often blackish ; rest of the scutum more reddish
