Records of Bees. 283 



Cape York is about 800 miles N.N.W. of Mackay, but the 

 specimens from the two localities show no difference. 



Megachile detersa, sp, n. 



? . — Length 10 mm. 



In all respects extremely close to M. quinquelineata, but 

 with the following differences : — Abundant hair of face (ex- 

 posing only upper part of clypeus, which has large, more 

 distinctly separated punctures) pale yellow ; eye3 greenish ; 

 flagellum much longer (about 3£ mm.), obscurely reddish 

 beneath ; anterior femora with a large brush of white hair 

 beneath ; outwardly directed tooth at end of anterior tibiae 

 smaller and more spiniform. Wings quite strongly dusky. 

 Apical dorsal segment of abdomen with fine appressed white 

 hair on disc ; hind basitarsus small and short, hardly longer 

 than the next two joints united ; middle tarsi with a fringe of 

 very long white hairs behind ; anterior coxae with short 

 triangular spines ; ventral scopa wholly absent, although the 

 specimen seems quite fresh. 



This remarkable specimen has many male characters, 

 although the abdomen is formed entirely as in all females, 

 with sting, &c. The antennae are 13-jointed! 



There can be little question that it is a very peculiar 

 gynandromorph (a result of hybridization?), but it was taken 

 from a series in the Turner Collection supposed to be all the 

 same. 



Hab. Mackay, Queensland, Feb. 1900 {Turner, 458). 



Aside from the gynandromorphic characters, this is evi- 

 dently distinct from M. quinquelineata, though it may be a 

 hybrid between quinquelineata and something else, perhaps 

 M. rhodogastra. 



Megachile rhodogastra, sp. n. 



$ . — Length 1L mm. 



Rather robust, but parallel-sided ; black, with the tegu- 

 ment of the sixth abdominal segment, the apical margin of 

 the fifth broadly, and the ventral surface of abdomen clear 

 ferruginous ; the fifth and sixth segments (except the basal 

 middle of fifth narrowly) are covered with short scale-like 

 yellowish hair, and also bear much erect yellow hair. 

 Head broad ; face densely covered with shining creamy white 

 hair ; clypeus normal ; mandibles black ; cheeks below with 

 a copious beard of white hair ; flagellum very obscurely 

 brownish beneath ; vertex, mesothorax, and scutellum closely 

 punctured, but the shining surface between the punctures 

 evident: vertex with dark fuscous, occiput with white hair;
