no. 1818. BEES IN THE NATIONAL MUSEUM. 2—COCKERELL. 245 



The collection contains three other species of Andrena from Pekin 

 which I fail to recognize, but they are in indifferent condition, and I 

 can not venture to describe them as new. 



NOMIA CHALYBEATA Smith. 



One male; Foochow, China (H. R. Caldwell). This agrees well 

 enough with Smith's description of his type from Shanghai, but 

 Bingham describes chalyheata, which he records from Tenasserim, 

 as having rufo-fulvous legs. I can only suppose that Bingham had 

 a different species. The Foochow specimen has a good deal of 

 black hair on the mesothorax and scutellum, and the flagellum and 

 apical margins of the wings are darker than Smith indicates. There 

 are, perhaps, several closely allied species or races of this immediate 

 group, but if so more material is needed for their elucidation. 



NOMIA PUNCTULATA Dalla Torre. 



Described from China. A male and female from Japan (Mitsu- 

 Tcuri) do not appear to differ in any respect. The female has three 

 emerald green bands on the abdomen, while the four of the male 

 are more bluish green. The species is very close to the Indian 

 N. elliotii Smith, but easily separated by the absence of a band on 

 the first abdominal segment. 



NOMIA TERMINATA Smith, var. a. 



Female. — Length about 14 mm., anterior wing 11^; black, without 

 any evident bands on abdomen; postscutellum unarmed; wings 

 strongly yellowish, the apex broadly clouded with fuscous. Hair of 

 head and thorax ferruginous, but on mesothorax and anterior part 

 of scutellum thin and mixed with fuscous; mandibles black; clypeus 

 shining, depressed in middle, with very strong, sparse punctures; 

 supraclypeal area elevated and punctured; clypeal keel or ridge 

 evanescent; abdomen shining, feebly punctured, the hind margins of 

 second and third segments at sides with pale yellowish tegumentary 

 bands. 



Two females from, Khow Sai Dow Mountain, 1,000 feet, Lower 

 Siam, February, 1899 (W. L. Abbott). On account of the feeble 

 clypeal keel, the rudiments of tegumentary bands on abdomen, and 

 the feebly punctured abdominal segments, I was inclined to regard 

 this as a distinct species. Close comparison with the descriptions of 

 Smith and Bingham convinced me that the insect was at best a 

 variety, however. Bingham states that the clypeal keel is slight, 

 and Smith says the abdomen is smooth and shining. The rudiments 

 of tegumentary bands may have been overlooked. 



N. aureipennis Gribodo, from Perak, is smaller (female, 11 mm.), 

 and the tegumentary bands on the second and third segments are 

 better developed, though interrupted in the middle. This, though 

 very closely allied, has better claims to distinction.
