RECLASSIFICATION OF MICROGASTERINI 193 



than in maia ; face virtually without a trace of punctation. 



Tergite 1 and sides of 2, outside the area delimited by the sulci, bright yellow ; 

 hypopygium short, subtruncate (Text-fig. 227) ; tergite 2 medially only about 

 two thirds as long as 3 ; (Text-fig. 228) ; 1st abscissa of the discoideus longer in 

 proportion to the 2nd than in maia ; front tarsus 5 (Text-fig. 222) 



formosus (Wesmael) 28 



Europe. 



Host: Abraxas sylvata Scopoli, Abraxas grossiilariala L., Bislon hirtaria Clerck 

 (Geometridae). Solitary. The larva, on leaving its host, makes a pedunculate, 

 pensile cocoon, a habit unique in the Microgasterinae so far as is known. 



5 Ocelli in a triangle with base very distinctly longer than sides, the distance between 



the posterior pair being very obviously greater than the diameter of the median 

 ocellus ............. 6 



- Ocelli in a triangle that is almost equilateral, the distance between the posterior pair 



being virtually not greater than the diameter of the median ocellus . . . 11 



6 Sulci of tergite 2 almost horizontally placed and directed towards the lateral margin 



of the tergite ; 1st abscissa of the discoideus about two thirds as long as the 2nd, 

 somewhat shorter in geometrivoms ........ 7 



- Sulci of tergite 2 more obliquely placed and directed towards the posterior corner of 



the tergite ; 1st abscissa of the discoideus hardly more than half as long as the 

 2nd. 



Medium brown species with the hind coxa and tergite 1 entirely yellow ; incom- 

 plete sulci of tergite 2 deeply marked at their origin ; this tergite shows no acicula- 

 tion ; hind tarsus somewhat short in relation to its tibia, very bristly and the flange 

 along ventral surface of segments 1-4 deep and conspicuous ; mesoscutum on 

 posterior half becoming less hairy and highly polished ; anteriorly the surface of the 

 mesoscutum is sharply punctate ; the lateral keel of the propodeum meets the 

 posterior keel at a well defined angle ; propodeum itself short (Text-fig. 225) 



cerates sp. n. 



Uganda: L. Victoria, Sesse Is., ix.1912, 9 $?, one the TYPE, 3 0*6". (G. D. H. 

 Carpenter) . Type in the British Museum (Nat. Hist.). 



Host: caterpillar with hairs and bristles, probably Arctiid. Gregarious with 

 white cocoons closely heaped in dense, somewhat cottony mass. 



7 Hind coxa entirely yellow .......... 8 



- Hind coxa black or dark brown ......... 9 



S Hypopygium in profile acutely pointed, angled at about 45 degrees ; lateral, excavate 



area of scutellum virtually unsculptured ; front claws large and with a deep, 

 narrow cleft between the lobe and the end of the claw ; hairs of the median cell 

 numerous and evenly distributed ; lateral keel of the propodeum completely in- 

 terrupted by the spiracle ; tergite 2 more transverse, only about two thirds as long 

 as 3. 



Thorax medium brown ; hind tibia having a very bristly appearance, the spines 

 of the outer side being strong ...... pompelon sp. n. 29 



Japan: Sapporo, 1 $, the TYPE. Type in the British Museum (Nat. Hist.). 



Host: The type bears a label: 'Wirt, Porthesia similis Fuess.' 



This is the only species of the group known to me in which the spiracle of the pro- 

 podeum completely interrupts the lateral keel but the value of this character 

 cannot be adequately assessed on a single specimen. 



- Hypopygium in profile almost right angled (Text-fig. 220) ; lateral, excavate area of 



scutellum showing normal rugosity ; front claws small and not easily seen, without
