I. ChalcogonatopnS' gigas sp. nov. 



Black, slightly aeneous, especially the abdomen, the whole 

 body and the legs clothed with conspicuous erect hairs. Clypeus, 

 mandibles, two basal joints of the antennae, the front tarsi except 

 the basal joint, the front coxae and trochanters, the middle and 

 posterior tarsi, more or less pale, yellowish or testaceous. Some- 

 times other parts of the legs are pale, the species being variable. 



Antennae long and slender, the fourth joint much longer than 

 the scape, the sixth three or four times as long as wide, the thiid 

 conspicuously longer than the fourth. Head dull, with extremely 

 dense, minute puncturation or surface rugulosity; the thoiax 

 with similar sculpture, the propodeum in front and posltrioily 

 with transverse rugosity also. Abdomen very dull and with 

 feeble scattered punctures, from which the erect hairs arise. 

 Length 5-7 mm. 



Hab. Bundaberg, Queensland; bred. 



2. Chalcogonafopns opfabilis' sp. no/. 



Nigroaeneous, with white pubescence, the face below the 

 antennae, the two basal joints of the antennae, the front tibiae 

 and tarsi, and the posterior and intermediate tarsi more or less, 

 pale-coloured, yellowish or testaceous. 



Head for the most part smooth and shining above, but near 

 th.e hind-margin of the eye densely punctulate; the antennae long 

 and slender, none of the flagellar joints being less than twice as 

 long as wide, the scape hardly as long as the fourth antennal 

 joint, and the third much longer than the latter. Thorax pubes- 

 cent, dull, or hardly shining; the pronotum indefinitely punc- 

 tured; the propodeum with excessively fine transverse rugulosity, 

 when seen under a compound microscope, and visible with a 

 strong lens. Abdomen with rather short, white, appressed hairs. 

 I-egs without erect hairs. Length 3-4 mm.

3. Chalcogoiiafopus dccoratns, sp. nov. 



Like the preceding in the nigroaeneous colour, but with the 

 antennae rather less slender, the scape, being as long as the 

 fourth joint. The clothing is quite different, consisting of grey 

 tomentosity, whereas in the preceding, especially on the abdo- 

 men, the individual hairs are very apparent. The pronotum is 

 red at the sides and posteriorly, and bears a distinct median
