Megachile cygnorum Ckll. 



Adelaide {ScJwmbiirgk) ; eastern Australia (Prciss). One speci- 

 men bears a label stating it to be the male of maciilata Smith 

 (macularis D. T.) ; it is possible that this reference is correct, but 

 the hair of the face is much lighter than " golden yellow," and there 

 are apparently other differences. 



NEW SPECIES OF PSAMMOCHARID^. 



By Nathan Banks, 

 East Falls Church, Va. 



The generic term, Psammocharcs, was first used by Latreille in 

 his " Precis." As with other genera in this work, no species was 

 mentioned. Its next appearance is in the Histoire Naturelle, Vol. 

 III., 1802, where, under the genus Pomphilns, Latreille says that he 

 had previously called this genus Psammochares, but preiers Pompilus, 

 since it is " phis donee des oreilles." A species is given, so that 

 Psammochares must date from 1802; others there are who would 

 •date in from the " Precis," 1796. In Latreille's later works 

 Psammocharcs appears as a synonym of Pompilus, but it appears to 

 have escaped most of the cataloguers. Pompilus is unfortunately 

 preoccupied, so that Psammocharcs will replace it. Mr. Fox has 

 suggested Anoplins, 1830, to replace Pompilus, overlooking Psam,mo- 

 chares. Mr. Fox has suggested also that the family be called 

 Ceropalid?e ; but Ceropalcs was proposed in the same work as 

 Psammochares, and on a later page; moreover, some writers consider 

 the Ceropalidse as a family just for the genus Ccropales; therefore 

 I shall employ Psamniocharidse.
