BEES IN THE QUEENSLAND MUSEUM.— COC'KEEELL. 
Paracolletes chalybeatus Erichson. 
Female : Russell Falls, National Park, Tasmania, 9-1-25. P. providus Smith 
is very doubtfully distinct. These bees need to be collected in series, with biological 
observations to determine whether there are several very closely allied species. 
P. chalybeatus is the type of Lamprocolletes Smith, which can be distinguished from 
typical Paracolletes by the well -developed stigma. The stigma varies very much in 
the group, and it is rather difficult to know where to draw the line. Leioproctus 
Smith, also with well -developed stigma, has priority of place over Lamprocolletes. 
It is figured as having a very long third cubital cell, with the second recurrent 
joining it far from the apex ; the type is the New Zealand L. imitatus Smith. P. 
chalybeatus , the type of Lamprocolletes , has the third cubital very broad but much 
less produced, receiving the second recurrent nervure very near the end. The 
longer type of cubital cell occurs also in Australian species, as for instance P. semi - 
lucens , described above : but it does not seem possible to regard this as a generic 
character. 
If we separate two genera on the character of the stigma, Paracolletes proper 
will include P. rebellis . P. ery thrums, P. nigrocinctus , P. callander, P. crassipes , P. 
fatifrons, P. ferricornis. Leioproctus will be by far the larger genus, with waterhousei, 
helichrysi , sigillatus , thornleighensis , platycephalus , fimbrialinus , gallipes, truncatulus, 
callurus, andreniformis , halictiformis , advena , subviridis, fervidm and fewidus subdolus, 
incanescens , tuberculatus and tuberculatm insular is, nitkhdus , abnormis , sexmaculatus, 
ibex , minutus, obscurus. chalybeatus, leal, argentifrons , monticola , hudsoni , atronitens, 
euphenax, nigrofulvus , launcestonensis , providellus and providellus bacchalis, vestitus, 
castaneipes, metallicus , boltoni. &c. It will also include the common metallic carinatus 
and plumosus of Smith. 
Hylseus gracilicaudus Cockerell. 
Female : King George’s Sound. Close to H. daveyi Ckll., but tegulae reddish, 
orange of postscutellum reduced ; first cubital cell very long. In this specimen 
the first recurrent nervure meets the intereubitus. 
Hylseus perconstrictus n. sp. 
Male. Length about 9 mm. ; rather robust, black ; face very bright orange 
(but surface dull and punctured) up to level of antennae, except the square 
supraelypeal area, which is entirely black ; the lateral face-marks above are partly 
excavated by the antennal sockets, and the truncate upper end is a little produced 
near orbits ; mandibles black, strongly bidentate ; la brum with a yellow spot ; 
scape black, ordinary ; flagellum long (reaching scutellum), obscurely brownish 
beneath, the joints subnodose ; third antennal joint partly red ; tubercles and 
scutellum (except extreme sides) bright orange, but rest of thorax wholly black ; 
mesothorax slightly shining, with large irregular punctures ; postscutellum shining ; 
area of metathorax short and poorly defined, somewhat shining, not evidently 
sculptured ; pleura strongly punctured ; teguke piceous, with an orange spot ; wings 
clear, with black (or reddish black) stigma and nervures ; second cubital cell very 
long, receiving first recurrent nervure very near base, second more remote from 
apex (in cotype the cell is shorter, and first recurrent enters extreme apex of first 
cubital) ; anterior and middle tibia3 with a pale reddish stripe in front ; basitarsi 
pale yellowish or creamy white, the tarsi otherwise pale reddish ; abdomen 
rugoso-punctate, first two tergites very strongly gibbous, with a deep constriction 
between, the elevation of the second tergite approaching the form of an obtuse keel.
