Species o/Eriocera in the British Museum. 89 



2-5; hypopygiuni, ovipositor, and the segment bearing the 

 ovipositor orange. Hi/popyyium : ninth tergite with tiie 

 central portion strongly produced, but emarginate in 

 the middle. Side-])iece less than twice as long as its basal 

 diameter, much narrower apically ; at the base on the 

 ventral side with a rounded prominence bearing a row of 

 about 15-20 short spines. Outer clasper bare, with a deep 

 excavation on the outer side near the base, preapical notch 

 small. Inner clasper rather narrow, incompletely separated 

 from the outer. Parameres rather long, straight, with 

 rounded tips, no basal tooth. Penis (if straightened) would 

 be a little longer than the side-pieces, but is bent downwards 

 and backwards about its middle ; both halves are strongly 

 curved; the outer (ventral) half bears numerous short bristly 

 hairs, which are most dense at the tip ; on the outer side 

 of the bend is a deep groove, tip not much thinner than base. 

 Legs long, slender, black ; claws of the male with basal tooth, 

 not much longer than the narrow empodium ; of the female 

 simple, empodium short and broad. TVings blackish at the 

 extreme base, beyond which rather more than half of the 

 wing is yelloAv; anal and axillary cells lighter. At the outer 

 edge of the yellow area is a clear whitish spot extending 

 across the basal cells but not reaching Rs or Cn. The apical 

 part of the wing, from the tip of Sc to the tip of Ax, is 

 blackish brown, except for the tip, which is rather broadly- 

 pure white. Sc ending opposite r, which is about tiiree 

 times its length from the tip of R^, and not quite its own 

 length from the base of Rs ; ^2 niore than three times as 

 long as R2+3; '"''* below base of Ro; cell j\Ii present, more 

 than twice as long as its stalk; Cu^a close to apex of discal 

 cell ; Cuj slightly curved. Halteres black.

14. Eriucera plumbolutea, sp. n., ^ . (Text-fig. 2 c.) 



Head velvet-black, with long and dense black hair. 

 Frontal tubercle triple, the pair of tubercles above the 

 anteunre rather small, but slightly larger than the unpaii^d 

 and more rounded dorsal tubercle. Anteunse with the scaj)e 

 blackish, first joint about three times as long as broad ; lirst 

 three flagellar joints yellow (remainder missing). Palpi 

 black (damaged). Thorax entirely velvet-black, except for 

 the prothoracic lobes, which are reddish and rather more
