SOME TASMANIAN BEES. 307 



Halictus cognatus, Bmith. 237 c (2323). Male. Launceston, 

 Jan. 25th, 1914. 



H. lanarius, Smith. 239 c (2335). Female. Devonport, 

 Nov. 2nd-5th, 1913. 



Halictus hamatopus, n. Bip. 238 c (2326). Launceston. 



(? . Length about 6 mm. ; black, with the tibiae, tarsi and apical 

 part of femora bright ferruginous, the middle tibiae 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 ; antennae black, the flagellum very long and crenulate ; abdo- 

 men broad, finely punctured, without hair-bands or patches. Looks 

 at first sight exactly like H. sanguinipes, Ckll., from Victoria, but 

 differs as follows : abdomen comparatively broad at base, not clavi- 

 form ; tegulae light orange-ferruginous ; apical field of wings dusky. 

 It is even closer to H. hicingulatus, 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. hicingulatus. 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 littleri, n. sp. 231c. Launceston. 



? . Length about 8-5 mm. ; black, including antennae and tarsi ; 

 bands of greyish -white tomentum at bases of abdominal segments, 

 reduced to a patch on each side of second; mesothoraxvery coarsely 

 punctured ; area of metathorax large, concave, finely striate ; tegulae 

 piceous ; wings dusky, second s. m. very large and broad. Close to 

 H. circumdatus, 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 ; tegulae much darker ; wings greyer, not at all yellowish, 

 with darker nervures ; area of metathorax much duller, the striae less 

 regular ; outer side of hind tibiae 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. gilesi, Ckll., and 

 H. asperithorax, Ckll. The front is microscopically grooved, the 

 grooves crossed at intervals by ridges. 



Nomia suhmcerens, n. sp. 

 246 c (2334). Bridport, Oct. 26th-30th, 1913. 



? , Like N. marens, 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 ; tegulae anteriorly with a pale 

 marginal spot. This could be regarded as an insular subspecies of 

 N. mcsrens.
