indeed and fall far short of the ends of the stipites. More- 

 over in the former the calcar of the hind til)i;e is con- 

 spicuously pectinate in the female, but not so in the eucalypti 

 group. 



In M. canaliculala the stipites are proh^nged at the apex 

 into a thin, recurved, elongate, downward-directed process, 

 narrowed on the apical half ; the membrane on the inner 

 side of the stipes is ciiiate with long bristles; outwardly 

 beneath the stipes, before the apex, another lobe is seen 

 beautifully and densely ciliated with long setse. The apical 

 processes are no doubt homologues of the membranous 

 lacinise of the eucalypti group, and are connected with the 

 inner membrane. 



In M. penetrata the apical processes are very slender and 

 almost filiform and wider on the apical than the basal portion ; 

 externally just before the point of origin of these processes 

 several long bristles are placed on a strongly chitinized line, 

 while internally the membrane is regularly ciliated with long 

 bristles, as in canaliculata. The small lol)e seen beneath 

 the stipes at about the middle of its length forms an acute 

 tooth bearing about four long setse, anterior to which is 

 another row of long setje directed downwards beneath the 

 stipes. 



Meroglossa soror, sp. n. 



Female black, shining, clothed with whitish pubescence ; 

 the head in front and the face bare or nearly so ; the clypeus, 

 cheeks, sides of face adjoining the clypeus, the plate above 

 it, and tlie scape of the antennae red. A minute and incon- 

 spicuous spot on the mesopleurae, one on the teguhe, and 

 one on the axillse yellow. Alesonotum shining, finely punc- 

 tured, not very closely on the disc ; postscutellum shining, 

 the punctures liner than the larger-sized ones of the scutellum. 

 Basal abdominal segment smooth, shining, finely and not 

 densely punctured except towards the sides, where is a lateral 

 apical line of pubescence, the other segments generally 

 pubescent. Almost similar to specimens of M. percrussa 

 taken by myself at Bunchiljcrg except for the difiereut colour 

 of the head and the dillVi-ent markings. It appears, how- 

 ever, to have a more shining and less strongly punctured 

 mesonotura and other slight distinguishing characters, and is 

 a little smaller.
