Note. — As the variations of the palpi in this genus are not 

 always indicated by any evident distinction in other external 

 characters, I have sought, where an opportunity offered, to 

 obtain a view of them in recent specimens ; but in many cases 

 have been obliged to content myself with relaxing the parts. 

 As, however, such minute characters may be easily mistaken 

 on a superficial view, I wish to enumerate the species whose 

 trophi were submitted to actual dissection : — Nos. 3, 5, 7, 8, 

 9, 10, 11, 17, 21, 22, 24, 27, 29, 30, 32, 34, m, 37, 39, 40, 

 43, and 44. A. H. Haliday.

 Helophoridae) ; 467. Aspilates gilvaria, (Le^\Ao^ie\'a.VhdX?e- 

 nidae) ; 468. Psithyrus rupestris, (Hymenoptera Apidae). 

 Psithyrus of Dahlbom and Curtis falls, because Psithyrus is 

 a name applied by Hiibner to a genus of Sphingidce. This 

 genus of bees is of very singular economy ; like the cuckoo, 

 it lays its eggs in a nest not its own : a circumstance unusual 

 among bees. The characters as laid down by Mr. Curtis do 

 not, we think, sufficiently distinguish it from Bombus. PI. 469.
