SOME JAPANESE BEES. 85 



London district, and nearly every tree between Putney and Kew 

 Bridge on the Surrey bank of the Thames is galled. It has also been 

 noticed at South Ealing, Brentford, Wormwood Scrubbs, and in St, 

 James's Park. The galled tree in Eed Lion Square, Holborn, was 

 pruned by the local authorities last spring in an attempt to exter- 

 minate the gall, but there is one specimen that has appeared on it 

 since then, and it will be interesting to see if the mites spread rapidly 

 again over the tree. The gall is also to be found on some willows 

 of an introduced species in Surrey, (ii) Bhahdophaga rosaria, H. 

 Lovsr. W. Glos. and Middlesex, (iii) Cryptocainpus ater, Jurine. 

 W. Glos. (iv) C. testaceipes, Zadd., was plentiful in one place in 

 Surrey last summer. 



S. alba, Linn. — C. testaceipes, Zadd. In the same locality as the last. 



S. caprea, Linn. — Bliabdophaga heterobia, H. Low. W. Glos. 



S. cinerea, Linn. — Cryptocampms saliceti, Fall. W. Glos. 



Populus nigra, Linn. — Pemphigus marsupialis, Courchet, as well 

 as P. bursarius, Linn, and P. spirotliecce , Pass, were plentiful on one 

 tree in the Wye Valley, Herefordshire. All three species of galls 

 have also been reported from Essex (J. Koss). 



Carex pendula, Huds. — Perrisia (? viuricatce, Meade). W. Glos. 

 (L. B. Hall). 



Dactylis glomerata, Linn. — Eriophyes tenuis, Nal., W. Glos.

SOME JAPANESE BEES. 



By T. D. a. Cockekell. 



The bees recorded below are in the collection of the United 

 States National Museum. 



Sphecodes japoniciis, Cockerell. 



Tokyo, Japan, both sexes, September 14th and 19th, October 9th 

 {Dr. C. Sasaki, 144, 172) ; Kiso-fukushima, July 23rd {Sasaki, 173). 

 This species was described from the male, without any more definite 

 locality than Japan. The female has the first abdominal segment 

 red, the sexual differences in the colour of the abdomen being exactly 

 as in the European S. sjnnulosus. The mesothorax of the female has 

 extremely large coarse punctures, but on each side of the middle 

 these are well separated on a shining ground, not nearly so dense as 

 in iS. fiiscipennis. The head of the female is very broad. This is 

 easily known from the other two species of Sphecodes recorded from 

 Japan by the strongly reddish-fuliginous wings. There seems to be 

 nothing in the description of S. ori2mdus, Ysichal (male) which would 

 contradict the suggestion that it is the male of S. simillimus, Smith. 



Megachile {Oligotropus) sasakiella, n. sp. 



? . Length 10-5 m.m., narrow, parallel-sided ; black, including 

 legs and antennae ; head and thorax strongly and densely punctured ; 

 sides of face, cheeks, sides of thorax, and metathorax with dull white 

 hair ; thorax above almost bare, no band in suture between meso-
