226 HYMENOPTERA. 



Halictus rowlandi sp. nov. 



9 . Length a scant 5 mm. ; head black, with the clypeus (except 

 its upper border) , labrum and middle of mandibles ferruginous ; front 

 moderately shining, but sides of vertex brilliant ; hair of head and 

 thorax white, very scanty and short; scape long, curved, light ferru- 

 ginous beneath , flagellum very obscurely reddish beneath ; tongue 

 short dagger-shaped ; thorax and legs entirely light rufofulvous ; area 

 of metathorax ill-defined, plicatulate at base ; mesothorax microscop- 

 ically tessellate, with scattered very weak punctures ; hind spur simple 

 (microscopically ciliate); tegulse pale testaceous; wings hyaline, 

 faintly dusky, iridescent, the very large stigma and the nervures dark 

 brown ; b. n. falling a considerable distance short oft. m. ; outer ner- 

 vures weakened ; first r. n. entering apical corner of second s. m., the 

 exact position variable ; third s. m. very small and narrow, smaller 

 than second ; abdomen broad, shining light rufofulvous or rufotestace- 

 ous, hind margins of the segments narrowly infuscated, and a slight 

 general dusky suffusion on the apical half; apical segment dark, the 

 rima reddish. 



A very distinct little species, totally different from all 

 others by its peculiar coloration, which recalls that of the 

 wasp, Pison melanocephalum Turner, also found at Cairns.

Halictus eyrei sp. nov. 



9 . Length a little over 5 mm. ; head and thorax yellowish-green, 

 abdomen and legs bright apricot-color; wings hyaline, stigma and 

 nervures pale yellowish-brown, outer nervures of third s. m. and third 

 discoidal evanescent ; mesothorax granular. Face pruinose with short 

 white hair ; lower margin of clypeus rather broadly black ; front mi- 

 nutely granular ; labrum pale reddish ; mandibles light yellow except 

 apex and base ; antennas ferruginous, apical half of scape above, and 

 flagellum above suffusedly, infuscated ; scutellum brassy, contrasting 

 with the pure green of the mesothorax ; area of metathorax broad, 

 ill-defined, obliquely wrinkled; posterior truncation with a sharp 

 lateral edge nearly to the top , tegulse clear testaceous ; third s. m. 

 about as broad as second, second receiving first r. n. some distance 

 from end ; tubercles light yellow with a dark mark ; coxae dark ; ab- 

 domen smooth and shining, with very shanty pale hair. 



In my table of Australian Halicti (Ann. Mag. Nat. Hist., 

 Sept., 1904) this runs to 11, and runs out because the ab- 

 domen is all red, except a very small dark spot on extreme 

 lateral margins of segments 3 and 4. By the black spots at 

 sides 3 and 4 it resembles H. punctatus exlautus Ckll,, but is
