IlaUdus occidens, Smith. 



Kiso-fiikiishima, Japan, Jnly 27, 1914 (S isakij 174). 



The lateral borders of posterior face of metathorax are 

 sharply ni:irgined. 'J'he hind spur has broa 1, rounded, 

 nodule-like teeth. 



Halietus tsusJinnensis, n. n. 

 Halictus on'entaJis, Perez, 1905 (not of Lepeletier, 1811). 



'l\'5us)iima, Japan. 



Allied to //. occidens, but with more punctured abdomen 

 and very smoky wings.

? . — Length about 8 mm.; anterior wing about 6'5 mm. 



Black, including the legs and hind margins of abdominal 

 segments ; head longer than broad, but not oval ; mandibles 

 reddened at apex ; head and thorax with abundant pale 

 ochreous hair, that on postscutellum light ferruginous ; 

 cly])eu3 shining and well punctured ; mesothorax very 

 densely punctured, but shining between the punctures ; area 

 of metathorax semilunai', rather short, with fine, regular, but 

 rather wavy longitudinal plicEe j posterior truncation very 

 hairy, not conspicuously defined ; tegulse piceons. Wings 

 hyaline, stigma and nervines amber-colour. Legs with pale 

 ochreous hair, a line of fuscous on outer side of hind tibia ; 

 hind spur very minutely nodulose, appearing simple under a 

 lens. First abdominal segment polished and shining, 

 minutely punctured all over, the base broadly and densely 

 covered with long ])ale ochreous hair ; remaining segments 

 also shining and punctured, the bases of segments 2 to 4 

 with entire bands of ochreous-tinted tomentum ; caudal rima 

 fringed with j)ale ochreous hair.

 signify I do not know. U.S. Nat. Museum. 



In the Japanese fauna it seems nearest to A. japonicola^ 

 Strand, bat it is larger and does not showtiie microscopic 

 sculpture between the punctures on mesothorax and first 

 abdominal segment. It is very close to H, perangulatuSy 

 Ckl'., from Formosa, but the posterior part of mesothorax is 

 much more closely punctured.
