Tibiœ omnes, praesertim anticœ et posticœ, femoribus breviores. Articulus p ri m us tarsorum posticorum ceteris duobus unitis subœque longus. Long.: cf 19 mill., $22 mill. Mas : anguli apicales segmenti secundi abdominis leviissime obtuse pfominuli; margines latérales segmentorum quattuor ulti- morum (parte circiter quarta basali excepta) serrati, in segmento tertio, quarto quintoque distinctissime, in sexto obsolète; anguli apicales segmenti sexti retrorsum acute dentato-prominuli; seg- mentum ultimum dorsale medio retrorsum rotundato- productuin ; tibiœ posticœ (vide fig.) superne subrotun- datim modice laminato-dilatatœ, paullo ante apicem obtuse calcaratœ, subtus e basi per très quadrantes longi- tudinis sensim fortius subsinuatim laminato dilatata^, dentem magnum compressum formantes, pone hune subito perpendiculariter fortiterangustatœ, deinde iterum leviter dilatatœ, lobulum apice oblique truncatulum formantes. Femina : anguli apicales segmenti secundi abdominis ne minime quidem prominuli; margines latérales segmentorum quattuor ulti- morum remote et obsoletissime serrulati ; anguli apicales segmenti sexti ultra latera genitalium eminuli, sed recti, retrorsum haud dentalo-prominuli ; segmentum génitale dorsale primum apice late arcuato-sinuatum, secundum apice profunde sinuatum ; tibiœ pos- tiche simplices, recta?, leviter compressas, apice subtus breviter cal- caratœ. Bornéo (Sarawak : J C. Moulton). Smaller than M. gracilis Westw., the only species bitherto described, and distinguished by the longer rostrum, the lack of the tooth at the apical angles of the second abdominal segment, the much less tuberculated hind femora having a single séries of tubercles (four in gracilis çf), the colour of the female tibiœ, and, above ail, by the total absence
