that sent to Dr. Packard. Not having Say's description, 

 1 am at a loss to understand his reason for naming this insect 

 sexuiaculatus. Is the male spotted ? or is it possible that 

 there are two kinds of females, as occur among the Apidae ? 

 If the latter is the case, has our Crabro one with six spots, 

 and the other spotless ? These questions are not penned 

 with a view of disputing ils identity. The words previously 

 quoted are conclusive that I communicated to Dr. Packard 

 what I then knew of its history. Thus, then, we have dis- 

 covered another species of the parasitic genus Crabro, gene- 

 rally known as sand wasps, imitating the habits of Prosopis 

 and Sphecodes among the Andrenidte and Ceratina, Xylo- 

 copa, and other wood-boring or what are termed carpenter 

 bees among the Apidae. With increased knowledge, 1 have 

 no doubt but that other species, hitherto classed among the 

 parasitic Hynienoptera, will be found making nests in similar 

 situations, and provisioning the cells with vegetable sub- 

 stances. — JVillinm Coil per ; Ottaiva, Ontario. — '^ Canadian

Locusts at Truro. — Several specimens of Locusta liiigra- 

 toria were taken in this town on the 9th of October : 1 have 

 only seen one of them, and that I have in my possession 

 alive. — Arthur Nix ; Miner's Bank, Truro, October 11. 



Locusts at East Looe. — I have now before me, under a 

 glass shade, two living specimens of Locusta migratoria — 

 one caught on the 10th and the other 11th Oct.: they feed 

 somewhat freely on any green vegetable, and are tolerabl}'- 

 active : they appear to use the spines on the back part of the 

 hind legs as a means of defence, which the captor of one of 

 them found by experience, as it caused four distinct punc- 

 tures at once, drawing blood from each. They appear in 

 excellent condition, not a mark or blotch on either. I see 

 by the local paper to-day that a specimen was taken at 

 Plymouth and one at St, Austle on Saturday last ; and I 

 hear that two were seen here on Friday, but not captured. — 

 Stephen Clogg ; East Looe, Cornwall. 



Locusts in Devonshire and Cornwall. — There have been 

 about thirty locusts taken in Plymouth and its vicinity, most 

 of them in the streets, a few in dwelling-houses : they 

 appear to have arrived early on the morning of the 9lh of 

 October, and not to have gone far inland, but to have
