MEMOIES OF THE QVEENSLAFl) AlUSEUH. 
4. M. hacked, Ckll. — Males, females, Kelvin Grove, September, Novem- 
ber, January, .March; Sunnybank, Septeml»er; IM'ibie Jsland, November. Tavo 
males and three females of this species Avere bred from an old clay nest of Abispaj 
Avhich Avas obtained at Darra on 17th June. The bees emerged on 23rd December. 
This species also belongs to tlie '' resin-Avorkers, ’ ' the cavities in the clay nest 
being lined and tlie entrance holes filled Avith resin in a similar manner to 
M. derclicta, but in these nests the resin is of a deep red colour and must be 
obtained from a tlifferent source. 
5. M. rhodogastra, CklL — j\Iales, females, Brisbane, Acclimatisation 
Gardeiis, November, February; also a A^ariety of mahi from same locality, Decem- 
ber. This species Avas bred from a nest tountl inside an iron i)ipe. The nest AAms 
of the usual elongate shajAC, made of i)icces of leaves, from Avliich live males and 
four females emerged. I should like to meniion that in fresh specimens of males 
the colour is deeper than as stated in Brob^ssor ('ockerelFs description, the hair 
on the sides and apex of the abdomen being orange, Avhile tlie hair on the face 
is pale golden. 
6. M. chrysopyga, 8m. — Males, females, Brisbane, September, October, 
March, April. On tloAvei-s of Davicsia iilicina. A nest of this species AA'as found 
at Kelvin Grove under some loose bark on a log. The cells Avere made of pieces 
of leaA^es, and the nest Avas of the usual cigar shape. ScA^en bees emerged in 
October. 
A enrious fact Avhich is brought to light by the preceding notes is that all 
the four species Avhich have been found to construct resinous nests liaA^e parallel- 
sided abdomens, while the tAvo leaf-cutting species Avlneli Aveve bred have shovel- 
shaped ones. This may he only a coincidence, hut sliould the analogy betAveen 
the form and habits of these bees remain constant, which can only be ascertained 
by breeding a larger number of species, it might be possible to dKide this very 
large genus into tAVo divisions according to the material Avhich they utilise for 
nesting purposes. 
7. M. pictiventris, Sm. — Brisbane, February; on tioAAxrs of Bxiranta. 
This species has a curious habit, when disturbed, of dropping from the floAA'er 
I)erpendicularly for eighteen inches or tAVO feet before taking Aving. It was 
OAving to the loss of soAxmal specimens through making a horizontal instead of an 
upward sweep Avith the net, that I became a.Avare of this peculiarity. A number 
of AA'asps belonging to the family Thynnida^ have a similar habit of dropping 
before taking Aving. 
8. M. austeni, Ckll. — Stradbroke Island, December; both sexes on floAvers 
of Lpomcea. The female, AA^hieh differs in ap]>earance from the male, has not 
previously been described. Female: Length about 15 mm.; expanse of Avings 
about 22 mm. Face clothed Avith Avbite hairs mixed with Idack. giving it a 
greyish appearance; checks, prothorax, and sides of median segment grey; vertex,
