view of disputing its identity. The words previously quoted are couclusive 

 that I couimunicated to Dr. Packard what I then knew of its history. Thus, 

 then, wc have discovered another species of the Parasitic Genus Crahro, 

 generally known as Sand Wasps, imitating the habits of Prosopis^' and 

 Sphecodes among the Andrenidcc and Ceratinaf, Xylocopa, and other wood- 

 boring or what are termed Carpenter Bees among the Apidœ. With in- 

 creased knowledge, I have no doubt, but that other species, hitherto classed 

 among the Parasitic Hymenoptera, will be found making nests in similar 

 situations, and provisioning the cells with vegetable substances.

 6-maculnfus as ••' Bluck, tera;um with three yellow soots on each si^la." 



MISCELLANEOUS NOTES. 



Mr. Couper'.s Tiiorn-leaf Gall. — Tn No. 8 of the Canadian Entouol- 

 ouiST, Mr. Coup'vr requests additional information respecting a Gall found 

 by him on Craiœgus crus-galli, which is said by him to be a " European 

 thorn." The common European white thorn, by the way, is Cr. oxijacantJia, 

 and Cr, crus-galli is an American species, according to Gray ; so that I 

 scarcely know what thorn he refers to. 



As to the Gall briefly described by him, I think it must be identical with 



a Cecidomyidous leaf-gall, which grows very sparingly near Rock Island, Ills., 



U.S., on Cr. tomcntosa. That Mr. Couper may judge for himself, I copy 



the description of my gall from my Journal. 



" Gall Ckat^egi bedeguak. — A sub-globul:ir gall, about 0.50 inch in diameter, 

 growing on the main-rib of the leaf of Craiœgus toraeniosa, generally below, but 

 sometimes above. It branches out into long slender sprangling filaments, which 

 are green and very often tipped with rosy, resembling those of the " bedeguar' 



* " Prosopis, though destitute of the usual apparatus for collecting honey, has been 

 recently proved a honey producer nevertheless. Its nest has been discovered in tubes 

 formed iu the main stems of the bramble, and in the nest, filmy cells, containing liquid 

 lioney. Sphecodes, though without the usual polleniferous organs, and consequently 

 thought to be Parasitic, has been watched by that indefatigable entomological observer, 

 Mr. F. Smith of the British Museum, while in the act of forming its burrow ; an act 

 which appears to afford conclusive evidence in favor of the non-parasitic habits of this 

 -genus of Bees. — Humphrys, in "The Intellectual Observer," May, 1862. 



f Spinola tells us " that one evening he perceived a female Ceraiina alight on the 

 branch of a bramble, partly withered, and of which the extremitj- had been broken ; 

 tmd after resting a moment, suddenly disappear. On detaching the branch, he found 

 that it was perforated, and that the insect was in the very act of excavating a nidus 

 for her eggs. He forthwith gathered a bundle of branches, both of bramble and wild- 

 I'ose, similarly perforated, and took them home to examine them at leisure. Upon 

 iaspection, he found that the nests were furnished, like those of the same tribe, with 

 balls of pollen kneaded with honey, as a provision for the grubs." — Annales du Museum
