FOUR INTERESTING AUSTRALIAN BEES. 17 



probably be removed from Anthoglossa at some later date. 

 Lamprocolletes veniistus, Sm., has golden abdominal bands like 

 A, aureotincta, and is, I believe, congeneric with it ; it may be 

 separated by its smaller size and ferruginous scape, as also the 

 colour of the legs. Paracolletes marginatus, Sm., seems also to 

 be closely allied ; it has the tibiae and tarsi a lively red. 



Prosopisteron, n. genus. 

 Small bees, similar in most respects to Prosopis, but with an 

 enormous stigma, much larger than the areas of the submarginal cells 

 combined, pointed at both ends, its apex on costal margin ; body black 

 marked with yellow (but no yellow on face), practically without hair, 

 but margin of tubercles fringed with fine plumose pubescence, clearly 

 visible under the compound microscope ; second submarginal cell 

 scarcely half length of first, and receiving both recurrent nervures, 

 near its base and apex respectively ; basal nervure curved, and falling 

 a little short of transverso-medial ; surface of wing with many very 

 short black bristles ; mesothorax microscopically reticulate, and with 

 large punctures ; scutellum similarly sculptured ; base of metathorax 

 microscopically reticulate, appearing dull and granular under a lens, 

 the enclosure not distinctly defined ; face fairly broad, microscopically 

 strigulose or aciculate ; anterior edge of clypeus concave ; ocelli rather 

 large, amber-colour ; labrum with a truncate process ; mandibles stout, 

 simple ; malar space short but distinct ; antennje quite ordinary ; 

 abdomen with a sericeous surface, the fine microscopical striae trans- 

 verse ; legs quite ordinary, all the claws strongly bidentate or bifid. 



Prosopisteron serotinellum, n. sp. 



2 . Length about C^ mm. ; black, with the upper border of the 

 prothorax broadly, and the tubercles, orange-yellow ; abdomen slightly 

 purplish, with a sericeous surface ; antenna3 long, black, the flagellum 

 dark brownish beneath ; stigma dark sepia-brown, nervures piceous or 

 black ; a dark fuscous cloud occupying nearly all of second sub- 

 marginal cell and much of apical part of first ; tegulje black, shining ; 

 spurs pallid. 



Hab. Queensland; " Ridg. 11. 93., 715" (Gilbert Turner). 

 A. very remarkable bee, easily known by the gigantic stigma. 



Euryglossa ichneumonoides, n. sp. 



3 . Length about 7 mm. ; head and thorax black, legs and abdo- 

 men yellowish ferruginous ; hair of head and thorax long, delicately 

 plumose, white, except on the upper part of head and thorax, where 

 there are some long black hairs, especially noticeable on hind part of 

 scutellum ; maxillary palpi very long and slender ; antennae very lono^, 

 alack, flagellum faintly brownish beneath ; clypeus very shiny, with 

 .arge well-separated punctures ; front and mesothorax dull ; tegulse 

 shming rufo-testaceous ; wings hyaline, beautifully iridescent, the 

 .arge stigma and the nervures ferruginous, the latter rather dark ; 

 second submarginal cell very large, a little longer than the first below, 

 j.-eceiving the first r. n. a considerable distance from its base, and the
