318 T. D. A. COCKERELL. 



Stenotritus. Ash mead places it in the Prosopidse, where it seems 

 quite out of place. 



P. tristis agrees with Parandrena andrenoides in having the t. m. 

 oblique and the first r. n. joining the second s. m. far from its base. 

 In Hesperapis rhodoceratus the t m. is not oblique, and the first r. 

 n. joins the second s. m. at its base. The Pasiphae also looks much 

 more like the Parandrena, though its face is all black, and the 

 stigma is not so large (being narrower), and the area is different. 



Since the mouth parts of Pasiphae take it out of the Andrenidse, 

 and the general structure and appearance remove it from the Pro- 

 sopidae, it seems that it can only rest in the Colletidre, as its posi- 

 tion in Dalla Torre's Catalogue would suggest. 



9IYDROSOMA Smith. 

 Mydrosoma metallicum Smith. 



Brazil. Looks like a rather large Andrena with dark greenish 

 blue abdomen ; structurally, of course, it is quite different. Mar- 

 ginal cell truncate. 



MEROGLOSSA Smith. 



Meroglossa canaliculuta Smith 



Australia. A very distinct thing; middle-sized, thorax and abdo- 

 men black and punctured, not unlike some Prosopis. Face very 

 peculiar, presenting a concave shining black impunctate surface, 

 divided up to level of antennae by a very broad raised sparsely 

 punctate longitudinal cream -colored band, the same raised pale sur- 

 face extending over the malar area, and as a narrow line up each 

 inner orbital margin ; ocelli large and prominent; scape much swol- 

 len ; area triangular, distinguished by absence of pubescence; claws 

 bifid ; only two submarginal cells, the second receiving both r. n. ; 

 second r. n. strongly bent, but without a double curve. In Ash- 

 mead's table it is said to have the stigma very small ; this is not at 

 all the case. As to the systematic position of the genus, cf. Trans. 

 Am. Ent. Soc. xxix, p. 185. 



CALLONELITTA Smith. 

 < alloiiiclitla pi eta Smith. 



Tasmania. ? . A curious bee, rather like a large Prosopis, but 

 wings fuliginous except at base, with three s. ms. ; and mesothorax,
