490 Mr. r. D. A. Cockerell — Descriptions and 



in subusta. The anterior and middle tarsi have long fringes 

 of white hair behind. 



Hab. Formosa {Sauter). Five males in Berlin Museum. 

 The type is from Koroton, first half of September^ 1907, 

 Two are from Koroton, Sept. 8 ; two from Kagi, Aug, 20. 



M. subusta and rufovittata are certainly distinct species, 

 yet extremely closely allied. 



Meyacldle aspernata, sp. n. 



$ . — Length about 10 mm. 



Black, with pale pubescence, which is white beneath and 

 on legs, above ochreous-tinted ; head broad, eyes pale 

 greenish, moderately converging below ; flagellum ferrugi- 

 nous beneath ; front very densely and minutely granular- 

 punctate, concave on each side ; vertex finely irregularly 

 punctured ; mesothorax and scutellum very densely granular- 

 punctate, like front ; area of metathorax dull ; tegular rather 

 light brown, with pallid margins. Wings hyaline; second 

 r.n. ending nearly as far from end of second s.m. as first 

 from its base. Legs black ; anterior coxae with strong spines ; 

 anterior femora with inner surface pale ferruginous ; their 

 tibise a little reddish apically, and behind with a brush of 

 white hair ; their tarsi with the first joint bearing a hollow, 

 boat-shaped scale or lobe, which is pale ferruginous ; the 

 anterior and middle tarsi are fringed with white hair behind, 

 the middle ones not only have a large thick fringe, but the 

 outer surface is densely covered with hair ; the hind tarsi 

 have a fringe of white hair in front. Abdomen rather short, 

 finely and closely punctured, with coarse hair-bands ; sixth 

 segment with the projecting edge broadly rounded, emargi- 

 nate in middle, and coarsely toothed ; dorsal surface of sixth 

 segment almost wholly covered with a dense mat of creamy- 

 white hair ; no subapical ventral teeth ; margins of third and 

 fourth ventral segments each with a little semicircular patch 

 of glistening appressed pale yellow hair, quite distinct from 

 the other pubescence. 



Hab. Takao, Formosa, July 1, 1907 {Sauter). One male 

 in Berlin Museum, the dorsal pubescence in poor condition. 



Very distinct from all other Formosa species by the 

 character of the anterior legs ; the dentate margin of the 

 sixth abdominal segment recalls the much larger and other- 

 wise quite different M. kagiuna. I cannot find any species 

 very closely related to M. aspernata.
