Perth, W. Australia (G. H. Hardy , 142). Looks like M. chrysopyga Smith, 
but hair of face not orange. 
Megachile dinognatha n. sp. 
Female. Length about 18*5 mm. ; very robust with very large, broad, and 
rounded head ; black, including mandibles, antennae, tegulse, and legs : hair of head 
and thorax very scanty, black on clypeus, white at sides of face, brownish white on 
front, dense and pure white at sides of metathorax, sooty on prothorax but white 
on tubercles : eyes purplish brown, strongly diverging below ; mandibles extremely 
massive, strongly punctured, with two large teeth and a long cutting edge ; clypeus 
very short and broad, very densely rugoso-punctate, the margin gently arched, 
shining and minutely crenulate ; supraclypeal area densely rugose like clypeus ; 
front with a pair of oblique obtuse ridges, which are polished and rather sparsely 
punctured ; vertex shining, with irregular punctures of different sizes ; cheeks 
very broad and rounded, polished, with scattered punctures ; mesothorax and 
scutellum densely rugose, base of metathorax shining ; wings dark fuscous, with 
violaceous tints ; legs with prevailingly brown hair, bright ferruginous on inner 
side of hind tarsi ; spurs dark : hind basitarsi not broadened ; abdomen finely 
punctured, shining on third segment but dull on fourth ; no hair-bands, but fifth 
and sixth segments covered with appressed copper -red hair ; the punctures at sides 
of third segment are large and sparse, while those on fourth are small and close ;

Hughenden (H . H. Batchelor ). I find no close relative of this species ; in the 
tables it runs nearest to the quite different M.ferox Sm. It must be associated with 
the species referred to the subgenus Eum,egachile.

anteriorly below, and the tubercles, have white hair ; mandibles massive, strongly 
grooved, with four large teeth : clypeus short and broad, dull, with a shining 
transverse apical ridge ; supraclypeal area polished and im punctate in middle :
