Descriptions of Hymenopterafrom Japan. 

 By Frederick Smith, Esq. 



In a Journal of British Entomology the following descrip- 

 tions would certainly appear to be quite out of place, but 

 there is a remarkable affinity between many of the Japanese 

 insects and those of Great Britain ; so close indeed is the 

 resemblance of some species that their distinctive differences 

 are extremely difficult of detection. This remark applies to 

 species of Lepidoptera, Coleoptera, and also to Hyme- 

 noptera. 



I have pointed out the British species which the Japanese 

 insects most closely resemble ; some of these are difficult to 

 separate from them. 



Colletes perforator. — Female. Length 5^ lines. Black, 

 punctured, the pubescence griseous. Head : the clypeus 

 covered with coarse longitudinal confluent punctures ; the 

 face, above the clypeus, with a thin pale ochraceous pubes- 

 cence ; that on the cheeks is cinereous. The thorax is 

 thinly covered above with pale ochraceous pubescence ; that 

 on the sides and beneath is griseous : the mesothorax is 

 closely and strongly punctured above ; the raetathorax ru- 

 gose ; the legs with griseous pubescence, the claw-joint of 

 the tarsi and the tegulae rufo-testaceous ; wings hyaline, the 

 nervures obscure testaceous. Abdomen shining, closely and 

 finely punctured ; the apical margins of the segments with 

 narrow fasciae of white pubescence. 



This species strongly resembles the C. Daviesana of 

 Europe, but is a more robust insect. 



Andrena halicloides. — Female. Length 5j lines. Black, the 

 abdomen shining. The head with vertex finely longitudinally
