ROHWER: Javanese Braconidae. 55 



Macrocentrus sp. 



Four males of an apparently new species of Macrocentrus reared from 

 larvae of Honiona coffearia were received from Mr. S Leefmans of Biiiten- 

 zorg, Java and accompanied by his letter dated November 27, 1919. As 

 only males are known it seems advisable to delay description until the 

 other sex can be studied. 



Microbracon leefmansi, new species. 



Female.— Length 3 mm. Face opaque, rather coarsely granular; antennae 26- 

 jointed, the basal joints not sharply separated, the apical joints well separated, the 

 terminal one sharply pointed and subequal in length with the preceding one; frons 

 opaque, rather finely granular; vertex and posterior orbits subopaque; ocelli in nearly 

 an equilateral triangle; the postocellar line shorter than the ocellocular; head receding 

 behind eyes; mesoscutum shining, behind its middle with distinct punctures; notauli 

 not foveolate; suture between scutum and scutellum foveolate; propodeum smooth, 

 polished; first tergite quadrate in outline; second tergite with a shining raised area at 

 the basal middle, slightly longer than the third and separated from it by a finely 

 foveolate furrow which medianly is curved anteriorly; second and third tergites striato- 

 reticulate on a granular surface, the sculpture on the second coarser; fourth and 

 following tergites granular; abdomen short, oval in outline; stigma broad receiving the 

 radius at about the middle; first abscissa of radius but little more than half the length 

 of the first intercubitus; nervulus slightly antefurcal; ovipositor as long as the abdomen. 

 Black; mandibles and palpi yellow; a small spot at superior-interior orbits, anterior 

 legs, mesosternum in part, apices of intermediate femora (more broadly so beneath), 

 base of intermediate tibiae, and basal joints of intermediate tarsi, testaceous; wings 

 dusky-hyaline; venation dark brown. 



Male.— Length 2 mm. Antennae 24— 25 jointed. Agrees with the above characteriz- 

 ation of female. 



Host. " Gracilaria theivora. 



Type-locality.— Goenoeng Mas (1200 M.) near Buitenzorg. 



Typ e.- Cat. No. 23455 U. S. N. M. 



Described from three females (one type) and three males (one allotype) 

 received under letter D from S. LEEFMANS who, in a letter dated November 

 27, 1919, states that it is a parasite of Laspeyresia species, in a subsequent 

 letter, dated Nov. 5, 21, the host is given as Gracilaria theivora. Named 

 for Mr. S. LEEFMANS.
