122 Mr. T. D. A. Cockerell—Descriptions and 
before me are about 9 mm. long, anterior wing 75mm. The 
first abdominal segment is highly polished d and impunetate. 
The insect is in all respects closely allied to H. sexnotatus, 
Kirby. 
Halictus occidens, Smith. 
Kiso-fukushima, Japan, July 27, 1914 (Susaki, 174). 
The lateral anne of posterior face of metathorax are 
sharply margined. The hind spur has broad, rounded, 
nodule-like teeth. 
Flalictus tsushimensis, nu. n. 
Hahetus orientahs, Pérez, 1905 (not of Lepeletier, 1841). 
T'sushima, Japan. 
Allied to HZ. occidens, but with more punctured abdomen 
and very smoky wings. 
Halictus basicirus, sp. 
¢ .—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 ; 
clypeus shining and well punctured ; ‘mesothorax very 
densely punctured, but shining between the punctures ; area 
of metathorax semilunar, rather short, with fine, regular, but 
rather wavy longitudinal plice ; posterior truneation very 
hairy, not conspicuously defined ; tegule piceous. Wings 
hyaline, stigma and nervures 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 
jens. First abdominal segment polished and_ shining, 
minutely punctured all over, the base broadly and densely 
covered with long pale 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 pale ochreous hair. 
Japan, marked 167 and 358, but what these numbers 
signify I do not know. U.S. Nat. Museum. 
In the Japanese fauna ib seems nearest to A. japonicola, 
Strand, but it is larger and does not show the microscopic 
sculpture between the punctures on mesothorax and first 
abdominal segment. It is very close to H. perangulatus, 
Ckl!., from Formosa, but the posterior part of mesothorax is 
much more closely punctured.
