brown, more or less powdery, the secondaries more whitish at base and more 

 obviously powdered than the primaries. 



Expands, 37-40 mm. =: i. 48-1. 60 inches. 



Habitat. — Claremont, California. 



Two males, two females, in good condition from Mr. C. W. Metz, 

 without dates of capture. The species is a very well-marked one in 

 the division with the well-marked ordinary spots and obsolete median 

 lines. The difference between the sexes is very marked and, at first 

 blush, the two do not look at all alike. The male is the smaller 

 with the primaries proportionately narrower and more pointed, while 

 the color is a clean bluish-gray with whit« secondaries. The female 

 has a sordid smoky and somewhat luteous tinge, and the secondaries 

 are decidedly smoky throughout. 



SOME AUSTRALIAN BEES IN THE BERLIN 

 MUSEUM.

About 180 species of Australian bees were described by F. Smith, 

 of the British Museum; I have published about 130 others, and in 

 addition some 35 have been described by various authors. I have 

 in manuscript a complete list, but it evidently represents only a small 

 part of the existing fauna. Every new collection is full of novelties, 

 especially if coming from a little searched locality. The present 

 paper puts on record some species in the Berlin Museum, for the loan 

 of which I am indebted to the kindness of Mr. Embrik Strand. 



Palaeorhiza perkinsi, new species.

 deep chestnut red, with a slight purple tint ; rest of abdomen very dark blue, 

 becoming black at apex, and with coarse black hair ; legs, except trochanters,
