278 Mr. T. D. A. Cockerell — Descrijrtions and 



Megachile sequior, Ckll. 



This species was described from a male labelled " Ade- 

 laide, Schombargk." 1 have reason for thinking that it was 

 really a Schultzian specimen from Port Darwin, which passed 

 through Schomburgk's hands. At any rate, four males were 

 taken by Turner at Port Darwin, Dec. 1902. The female, 

 not before described, is represented by a specimen from 

 N.W. Australia (C. F., Turner Collection), in the British 

 Museum. It is about 11£ mm. long, the thorax six-spotted 

 like the male, the pubescence also coloured as in the male ; 

 flagellum dull ferruginous beneath ; eyes green ; ventral 

 scopa white, black on last segment. It is very close to 

 M. macularis, D. T., and would at first sight bs taken for it, 

 but it may be separated by the black hairs which project at 

 sides of abdomen being confined to the fifth and sixth seg- 

 ments, and also by the green eyes. 



■ Megachila rhodura, Ckll. 



The female, hitherto unknown, was taken by Mr. Turner 

 at Mackay, Queensland, at flowers of Eucalyptus, Dec. 1899. 

 It is about 12^ mm. long, in general similar to the male, the 

 tegument of the last segment, and the penultimate except at 

 base, red, covered with fine appressed fulvous hair, which 

 also extends forward over the fourth segment. Head large, 

 oblong, the eyes slightly diverging below ; sides of face with 

 pure white hair; middle of lower edge of clypeus with a 

 small nodule, defined by a notch on each side ; eyes light 

 green ; mandibles long, the cutting-edge thickly fringed with 

 red hair, in the manner of M. trichognatha, Ckll., which is 

 related ; ventral scopa entirely white. 



Megachile trichognatha, Ckll. 



A new locality is Victoria (C. F., Turner Collection). 

 British Museum. M. ferox, Sm., bears the same data; it 

 was described from Swan .River. M. tomentella, Ckll., also 

 occurs in Victoria (C. F.) and by Swan River.

<£. — Length ]0 mm. 



So close to M. rhodura that only careful comparison shows 

 it to be different. Abdominal segments 3 to 6 have the 

 tegument chestnut-red, a darker tint than the red of rhodura ; 

 the abdomen is broader, and the large apical lobes are wider 

 apart ; the tarsi have longer and more abundant hair, and the
