ÖAHAN: Parasitic Hymenopiera. 4d 



Described from three female specimens received with letter dated 

 November 27, 1919, from Mr. Leefmans under his lot C, and said to 

 have been reared from the larva of the above named host. All three 

 specimens mounted on card points. 



Pleurotropis lividiscutum, new species. 



This species apparently differs from ail other oriental species of the genus in 

 having the scutellum black with a broad median longitudinal stripe of bright steel blue. 



Female. — Length 1.75 mm. Antennae 8-jointed; scape slightly fusiform, nearly 

 cylindrical; pedicel about twice as long as broad; apparently only a single ring-joint; 

 funicle three-jointed, the joints each with a short peduncle at apex; funicle joint two 

 oblong, very slightly shorter than one; joint three exclusive of the apical peduncle 

 subquadrate; club scarcely thicker than the funicle and a little more than two-thirds 

 the length of the last two funicle joints combined, distinctly two-jointed, the basal 

 joint subequal in length to the last funicle joint, the second joint conic ovate, about 

 three-fourths as long as and much narrower than the basal joint and terminating in a 

 distinct spur. Head viewed from in front semicircular, broader than long, the vertex 

 straight, beneath evenly rounded or nearly; vertex and frons above the frontal ledge 

 strongly and rather coarsely reticulate punctate, below the frontal ledge to base of 

 antennae similarly but not quite so coarsely sculptured; a narrow area immediately 

 below the bases of antennae and extending from one eye margin to the other nearly 

 smooth and polished; oral region and the cheeks finely reticulate-punctate; eyes hairy; 

 dorsum of pronotum weakly margined anteriorly and nearly smooth; mesoscutum 

 reticulate-punctate, with the two depressions before the scutellum finely obliquely 

 striated; scutellum medially and apically reticulate, laterally longitudinally striated; 

 propodeum mostly polished, the paired median carinae slightly separated at base and 

 diverging posteriorly; spiracles small and circular; posterior tibial spur slender and 

 reaching to the middle of second tarsal joint; marginal vein much longer than the 

 submarginal; postmarginal and stigmal subequal, the former very slightly the longer; 

 abdomen a little longer than the head and thorax combined, distinctly petiolate; the 

 petiole rugose and twice as broad as long; first tergite beyond the petiole comprising 

 approximately two-fifths of the total length of abdomen, smooth and polished; tergites 

 beyond the first subequal and very faintly reticulated; ovipositor not exserted. Dorsal part of 

 head and smooth part of face more or less blue-green ; antennae including scape black with a 

 metallic reflection; palpi pale; broad median stripe down the middle of scutellum andthe apex 

 laterally, comprising the reticulated portion, metallic blue; propodeum brassy green;remain- 

 der of thorax and all legs except their tarsi black with a faint purplish tinge in some lights; 

 tarsi except apical joint pale; abdomen purplish black, the first tergite bluish in some lights. 



Male unknown. 



Type locality. — Padang, Sumatra. 



Type.- Cat. No. 24657 U. S. Nat. Mus. 



Described from four female specimens, two of which are badly broken, 

 received from S. LEEFMANS under his Lot No. 4 of letter dated April 8, 

 1919, and said to have been reared from cocoons of a Braconid specimens 

 of which were also sent under his No. 3. The host has been determined by 

 S. A. ROHWER as a new species of Apanteles and will be described by him. >) 



Antennae from a paratype mounted on a slide; other material mounted 

 on card points.
