480 Mr. T. D. A. Cockevell — Descriptions and 



with a very broadly interrupted yellow band, excavated 

 behind sublaterally; fourth to sixth with yel'ow bands, 

 interrupted by a red spot on each side ; apical plate broad, 

 notched ; venter red with yellow bands. 



Tokyo, Japan, April i2, 1909 (Sasaki). U.S. Nat. 

 Museum. It is also labelled Yamada. 



In the table of Palsearctic species it runs near N. manni, 

 Moraw.3 differing by the black scutellum. It is quite dis- 

 tinct from all those described from Japau. It is a large 

 species of Nomada, s. str. 



Nomada pyrifera, sp. n. 



$ . — Length about 10 mm. 



Head and thorax red with black markings, closely punc- 

 tured, the hair white ; labrum pale yellow, with no distinct 

 tooth ; malar space pale yellowish ; mandibles simple, red, 

 black at apex; lower part of clypeus, and lower part of 

 supraclvpeal area, suffusedly yellowish ; middle of front, 

 extending to occiput, black, and cheeks black with a broad 

 red band behind eyes ; antenna? entirely red, long, reaching 

 to base of abdomen ; third joint scarcely half as long as 

 fourth (this at once separates it from the superficially 

 similar N. japo?iica, Sm.) ; mesothorax with three black 

 bands, confluent in front ; scutellum strongly elevated, 

 entirely red ; area of metathorax black in middle and red 

 sublaterally; pleura nearly all red; no yellow on thorax; 

 tegulse pale red. Wings clear, dilute fuscous at apex ; 

 stigma ferruginous ; nervures fuscous ; b. n. going far basad 

 of t.-m.; second s.m. very broad, receiving first r. n. about 

 middle. Legs bright ferruginous, hind femora with a black 

 stripe behind. Abdomen smooth and polished, ferruginous ; 

 basal half of first segment black, second segment with a very 

 large pyriform (pointed mesad) spot on each side ; fourth 

 and fifth segments with yellow bands, failing laterally ; 

 venter with broad yellow bands.

This also runs near N. manni in the Paltearctic fauna, but 

 is readily distinguished by the pattern of abdomen and the 

 red scutellum. Sasaki collected two males, of different 

 species, which looked like N. pyrifera. One I have described 

 as N. calloptera, as it differs from pyrifera in the colour of 

 the stigma and the basal nervure going less basad ; the other, 

 collected at Tokyo in April, I suppose to be the true male 

 of pyrifera. It is unfortunately in very bad condition, but
