SOME TASMANIAN BEES. 307 
Halictus cognatus, Smith. 287 ¢ (2323). Male. Launceston, 
Jan. 25th, 1914, 
H. lanarius, Smith. 2389¢ (2335). Female. Devonport, 
Noy. 2nd—5th, 1918. 
Halictus hematopus, n. sp. 288¢ (2326). Launceston. 
3. Length about 6 mm.; black, with the tibix, tarsi and apical 
part of femora bright ferruginous, the middle tibize with a faint dusky 
stripe on outer side; labrum and mandibles dark, but clypeus with a 
broad pale yellow band, with an angular projection into the black 
above; antenne black, the flagellum very long and crenulate ; abdo- 
men broad, finely punctured, without hair-bands or patches. Looks 
at first sight exactly like H. sangwinipes, Ckll., from Victoria, but 
differs as follows: abdomen comparatively broad at base, not clavi- 
form ; tegule light orange-ferruginous ; apical field of wings dusky. 
It is even closer to H. bicingulatus, Sm., differing by the wholly black 
flagellum, the large amount of black on femora, the longer stigma 
and the shining, more distinctly punctured abdomen. It could be 
regarded as an insular subspecies of H. bicingulatus. My male 
bicingulatus is from Brisbane; it is possible that specimens from the 
coast opposite Tasmania would more nearly approximate to the 
Tasmanian bee. 
Halictus litileri, n. sp. 281¢. Launceston. 
?. Length about 8:5 mm.; black, including antenne and tarsi; 
bands of greyish-white tomentum at bases of abdominal segments, 
reduced to a patch on each side of second; mesothorax very coarsely 
punctured ; area of metathorax large, concave, finely striate; tegule 
piceous ; wings dusky, second s. m. very large and broad. Close to 
H. circwmdatus, Ckll., from Victoria, but differing thus: clypeus 
rough, more closely punctured, less shining; vertex and mesothorax 
with conspicuous black hair; middle of mesothorax more densely 
punctured ; tegulz much darker; wings greyer, not at all yellowish, 
with darker nervures ; area of metathorax much duller, the striz less 
regular; outer side of hind tibiz with much black hair. The second 
abdominal segment is finely punctured, except the broad apical part, 
which is minutely lineolate, with only scattered rudimentary punctures ; 
a useful character to separate the species from H. gzlesz, Ckll., and 
H. asperithorax, Ckll. The front is microscopically grooved, the 
grooves crossed at intervals by ridges. 
Nomia submerens, n. sp. 
246 c (2334). Bridport, Oct. 26th-30th, 1913. 
?. Like N. merens,Sm., but metathorax different, the transverse 
cross-striated channel much narrower in middle, its lower margin 
straight except at sides, where it rather abruptly bends upwards ; 
wings shorter, nervures darker; tegulze anteriorly with a pale 
marginal spot. This could be regarded as an insular subspecies of 
N. merens.
