The species is named in honour of my friend Dr J. R. Steffan (MNHN, Paris), 

 who was the first to contribute substantially to the knowledge of the genus 

 Micrapion. 



Micrapion sp. indet. A 



(Text-figs 270-272) 



Very similar to M. steffani sp. n. in the form of head (at least in the male), of 

 hind coxa and femur and in the form of gaster both in female (cf. Text-figs 267, 

 270, 272) and male (Text-fig. 271). Therefore the following description puts stress 

 on the differences between the two species. 



$. 2'3-4'7 mm. Larger $: black, turning red on margins of pronotum, sides of thorax, 

 propodeum, base of gaster and legs; pale yellow are: anterior and posterior band on pronotum, 

 tiny adtegular spot on mesoscutum, posterior band (dilated laterad) on scutellum, broad 

 subtriangular macula on either side of fourth tergite, broad subcrescentic horizontal band on 

 apex of fifth tergite crossing sheaths in nearly their whole length, then all tibiae dorsally, hind 

 femur ventro-basally and with a spot dorso-apically. In small (apparently dwarf) specimen 

 markings anteriorly on pronotum, on mesoscutum and scutellum, on sixth tergite and hind 

 femur missing. Wing infumation as in M. steffani. 



Head in small specimen (missing in larger one) broader than pronotum as 47 : 41, in dorsal 

 view only 1 -74 times as broad as long, strongly regularly convex, convexity of vertex and frons 

 in one smooth curve, protuberances not differentiated. Lateral ocellus nearly twice its diameter 

 from eye, median ocellus one diameter from scrobes, latter barely carinate dorsally. POL 

 about twice OOL. Inner orbits hardly emarginate. Relative measurements: breadth of 

 head 47, height 46, frontovertex 32, scrobes 16-5, lower face 26-5, its height 20, eye 27 : 19, 

 malar space 14, mouth 13. Length of flagellum plus pedicellus 0-95 breadth of head, flagellum 

 strongly clavate, all segments transverse, first flagellar segment slightly shorter than pedicellus, 

 only half as broad as clava; latter only 1-25 times as long as broad, bluntly subacuminate. 



Thorax and gaster much as in M. steffani but puncturation much denser and accordingly the 

 pubescence. Pronotum dull, very narrow interspaces microscopically cross-striate. On 

 mesoscutum interspaces slightly broader, on disc dull, striate and about a quarter as broad as 

 punctures, posteriorly still broader, broadest anteriorly on scutellum and at hind corners of 

 mesoscutum where slightly shiny. Thorax dull everywhere in the small specimen. With 

 denser puncturation also hind coxa at base of lateral edge densely punctured and fairly densely 

 pubescent, extension of puncturation in the depression about as in M. steffani, but impunctate 

 part more distinctly cross-striate. 



For gaster see Text-figs 270, 272; puncturation fairly dense. 



6*- 3'7~4'° nirn. Anterior pale yellow line on pronotum more or less reduced, present on 

 scutellum, gaster with broad vertical sublateral streaks in front of broadest place and with broad
