shorter than tlic fifth. The strongly i-aiscd hind margins of 

 the ahdoiuinal segments giv(^ it a very peenliar aspect. The 

 type of A. milsKkurii also hears the nnmhers 35^ (5, "Z^, and 

 something in Japanese. 



Atidrena watasei, sp. n. 

 S . — Length about 10^- mm., ex|)anse abont 18.

 liair of head and thorax rather long and abundant, greyish 

 Avhite, dorsally with oidy the faintest ereamy tint, but some 

 daik grey or blackish hair on scape, sides of front, and 

 middle of thoracic dorsum ; discs of abdominal segments 

 beyond the second with more or less sooty liair, and that of 

 apex pale sooty ; the abdomen in general, especially the 

 second and third segments, is thinly clothed with pale hair, 

 Avhich forms thin inconspicuous bands on the hind margins 

 of the segments, but only at sides on first, lu'oadly inter- 

 rnpted on second, and very Aveak in middle of third. Legs 

 with white hair, pale purplish brown on inner side of tarsi. 

 Head much broader than thorax ; face covered with long

 joint rather short, but longer than fourth ; mesothorax and 

 scutellum very shiny, with rather small but distinct and 

 well separated punctures ; mesothorax dull in front ; meta- 

 tliorax Avith very long hair, the area finely rugulose, not 

 defined ; teguhe piceous. Wings strongly reddish, paler ■ 

 basally, stigma and nervures ferruginous; b.n. meeting 

 t.-c. ; second s.m. a little broader below tlian high, receiving 

 r. n. a little beyond middle. Legs black, slender, ordinary.

Hub. Japan (U.S. National Museum, 132). Also labelled 

 35. 9. 



In Schmiedeknechl's table runs to 154, and runs out 

 because wings are dusky and area of metathorax is only 

 rugulose. It can be run on Avith some difficulty to A. pro- 

 pinqua, from which it differs by the larger size, dark apical 

 margins of abdominal segments, and generally pale hair of 

 head and thorax. The general build and appearance of the 

 insect is very like that of the American A. sayi, Rob., but 

 the mesothorax is quite difierent. No closely similar 

 Japanese species has been described.
