REVISION OF LEUCOSPIDAE 225 



short anterior lines on pronotum, angulate interrupted band on fourth tergite and broad band 

 on fifth tergite crossing upper half of sheaths above red apex, then dorsal edge of fore tibia, 

 apical half of mid tibia, ventro-basal streak on hind femur, hind basitarsus. Sometimes 

 yellow reduced on pronotum anteriorly or, to the contrary, extended, forming lateral lines on 

 mesoscutum, apical band on scutellum, dorso-apical spot on hind femur and on fifth tergite 

 extended, replacing red, to hind margin. Fore wing subhyaline but with abruptly dark apical 

 sixth connected by a line with stigma and a streak along postmarginal vein. 



In shape and structure similar to M. congoense and M. bilineatum. Head below eyes 

 narrower and more produced (Text-fig. 266), in holotype malar space fully i-i times as long as 

 width of mouth (other specimens 1-10—1-15 times so) and 0-45-0-55 the length of eye. In 

 lateral view lower face distinctly convex. Head dorsally about 1-9 times as broad as long, in 

 facial view in holotype 1-04 times as broad as high; face with very dense white pubescence. 

 Antenna subclavate. 



Pronotum with barely distinct depressions. Puncturation on mesoscutum dense, very 

 narrow interspaces with distinct microreticulation or striation. Hind coxa densely punctured 

 dorsally but in depression only in a reduced wedge-shaped area from base to middle, impunctate 

 parts transversely striate. Hind femur rather densely punctured (slightly more than in 

 average M. congoense, less so than in M. bilineatum), rather slender, including teeth 1-81-2-00 

 times as long as broad. First tergite about 1-7 times as long as broad, densely punctured, 

 behind first third medially subdepressed and with elevated smooth median line. Puncturation 

 of fifth tergite moderately coarse, dense, tergite in lateral view slightly longer than high. 

 Sheaths o-66-o-72 times as long as hind tibia, their furrow steeply ascending, bordered by 

 sharp ridge or carina, this highest below middle and at top which is half way between apex of 

 fifth and the very sharp-angular apex of fourth tergite; top elevation moderate, not auricle-like, 

 furrow strongly narrowed in front of it and obliterated. 



<£. 4-6-5-9 mm. Very similar to $ in colour (but red more reduced) and shape of head, 

 thorax, legs (but mid tibia all whitish) and wings. Antenna still less clavate, flagellum plus 

 pedicellus about 1-2 times as long as breadth of head. Gaster on broad part with usual inter- 

 rupted cross-band anteriorly and horse-shoe macula posteriorly. Anterior part very narrow; 

 relative measurements: narrowest part behind first tergite 10-5, broadest part 39, length of 

 gaster 96, first two tergites combined (second measured to its apex on epipleural carina) 33, 

 first tergite 20 : 13, its sides slightly narrowing caudad. Sternites narrow; fourth slightly, 

 fifth and sixth distinctly elongate and broadly concave.
