RECLASSIFICATION OF MICROG ASTERINI 271 



China. Type in British Museum (Nat. Hist.). 



The disc of the scutellum is strongly margined laterally and is divided by irregular 

 keels into a number of rather deep excavations. The flagellar segments are only 

 weakly flattened. 

 Thorax blackish or dusky reddish-black ; notaulices deep and rugose ; middle lobe of 

 the mesoscutum strongly raised above the lateral lobes and terminating behind in a 

 fine keel that separates the two posterior troughs of the notaulices ... 3 



Propodeum so coarsely reticulate that the sculpture consists of deep excavations sur- 

 rounded by strongly raised keels ; between the medial longitudinal keel and the 

 lateral keel not more than 3-4 such excavations can be counted in a transverse row ; 

 middle lobe of the mesoscutum very strongly raised ; tergite 1 about three times as 

 long as its apical width ; thorax more or less dusky reddish-black. 



Temples decidedly rugulose ; species approaching vollenhovii in general habitus 

 and coarseness of sculpture .......... 4 



Propodeum less coarsely reticulate but more densely so, the number of reticulations on 

 the dorsal surface between the medial keel and the lateral margin much more 

 numerous when counted along a transverse row ; middle lobe of the mesoscutum 

 less strongly raised, the notaulices shallower ; tergite 1 only slightly more than 

 twice as long as its apical width ; thorax deep black. 



Wings very dark brown ; in general reduction of sculpture, this species is much 

 more like strongly sculptured species of Microplitis than Snellenius 



theretrae (W'atanabe) 68 



Japan. Only 1 male seen, a paratype, in British Museum (Nat. Hist.). 



Host : Theretra nessus Drury ; cocoon apparently dark brown with ribbing. 

 Head from above deeply emarginate between the almost angular corners of the 

 temples ; fore wing almost hyaline but darkened beyond the areolet and with a still 

 darker cloud beneath the stigma ; scutellar hollows unusually large, slightly longer 

 than wide, flowing together behind the medial keel and here margined on each side 

 by a thick, strongly raised keel ; mesopleurum beneath the wing insertions with 

 deeper excavations. 



Hind femur with well developed inner keel on apical two fifths 



philippinensis (Ashmead)" 9 



Borneo: Kuching. One male and one female of bimaculatus in British Museum 

 (Nat. Hist.), both labelled type. The male has the head slightly less excavate 

 behind the eyes than the female. The antenna is broken in both specimens. 

 Head from above only very weakly emarginate, the corners of the temples not at all 

 prominent ; fore wing dark brown ; scutellar hollows deep but slightly transverse 

 and not flowing together behind and without the raised keel on each side seen in 

 philippinensis ; mesopleurum beneath the wing insertions with smaller, shallower 

 excavations. 



Tergite 1 behind without the V-shaped area that occurs at the apex of the tergite 

 in philippinensis ; flagellar segments feebly flattened ; middle lobe of the mesoscu- 

 tum, considered without the long, sharp, posterior keel, almost truncate behind ; in 

 philippinensis, the posterior keel forms merely a sharply pointed extension of the 

 middle lobe ; further, the middle lobe in gellens is deeply, longitudinally hollowed 

 out on each side of a raised, medial thickening ; inner side of hind femur with well 

 developed keel on apical two fifths ....... gelleus sp. n.
