MEMOIRS OF THE QUEENSLAND MUSEUM. 
Megachile gilbertiella Cockerell. 
Female : Gordonvale, Oct. 1, 1922 (W. C. Dormer). 
Megachile ciliatipes Cockerell. 
I cannot separate this from the male of Androgynella detersa Ckll. Search 
should be made in Brisbane for Androgynella females. 
Megachile cetera Cockerell. 
I find no satisfactory character to separate the female of the Hawaiian 
M. timberlakei Ckll. from M. cetera. I have no Australian male closely resembling 
M. timberlakei. 
Megachile alani n. sp* 
Female. Length 11*5 mm., varying to 9*5; rather robust, but of parallel- 
sided type : black, including legs, mandibles, and antennae, but tegument of sixth 
abdominal segment (above and below) and narrow apical margin of penultimate 
tergite, clear ferruginous : head large and broad, orbits slightly diverging below ; 
mandibles very robust, strongly grooved, parallel -sided, the apical margin with 
three very short rounded teeth : clvpeus broad and short, the anterior margin 
strongly concave, forming a broad arch, in the middle with two very large shining 
pits, separated by a small ridge, the elypeus otherwise very densely piuictured ; 
upper edge of elypeus shining but supraclypeal area densely and finely punctured ; 
sides of face, on each side of supraclypeal area, dull and minutely granular, and front 
the same ; vertex broad, closely but irregularly punctured ; cheeks broad, the 
surface finely grooved or striate : a tuft of white hair at each side of face ; front 
with thin white hair : vertex with very thin short brownish hair ; mesothorax and 
scutellum dull and very densely punctured ; conspicuous dense white hair-spots 
at posterior angles of mesothorax, at sides of prothorax, fringing tubercles, and 
(very small) between scutellum and mesothorax ; mesopleura densely rugoso- 
punctate ; thorax with very little hair, the pleura and metathorax showing loose 
white hair ; tegulse very dark reddish brown ; wings hyaline, nervures and stigma 
dark ; second cubital cell long, receiving first recurrent nervure at a distance from 
base about equal to half first intercubitus ; legs with pate hair, conspicuous and 
silvery on outer side of tarsi, especially middle tarsi ; hind tarsi not broadened ; 
spurs whitish ; abdomen convex, closely punctured, the hair- bands very inconspicuous, 
fulvescent, except pure white tufts on each side of first segment : apical segments 
with short appressed fulvous hair ; ventral scopa. white, fulvous at extreme tip. 
Two from Moree, N.S.W., March 1923 (Alan P. Dodd). It is very like 
M. rhodura Ckll., but easily separated by the structure of the elypeus. In some 
tables it runs to M. modesta Sm., but that has the tegument of the apex of the 
abdomen black. 
Megachile chrysopygopsis n. sp. 
Female. Length about 12*5 mm. ; broad and robust, with broad abdomen ; 
black, including legs, but flagellum chestnut-red beneath, and apical tooth of mandibles 
red ; mandibles broad, quadridentate counting the inner corner ; elypeus ordinary, 
shining but closely and coarsely punctured, lower margin simple, nearly straight : 
supraclypeal area in middle of disc highly polished and shining ; front and sides of 
face with long rather dull white hair ; vertex with dark fuscous hair ; cheeks with 
long white hair ; mesothorax and scutellum shining but closely and very distinctly 
puncurted ; pleura and metathorax with long dull white hair ; sides of mesothorax
