6. One about the same time in "Westgate, Huddersfield, now in 

 tlie local collection of the Huddersfield Naturalists' Society. 



7. Another about the same time was taken in the prison yard at 

 "Wakefield, is the property of Mr. William Talbot, and is the largest 

 specimen of the series. 



8. On the 1st September, one was captured in a field at Acaster 

 Malbis, on the Ouse below Tork, perched upon a sheaf of com. This 

 I have not seen. 



9. Another specimen taken at Wakefield; date not known. 

 Reported to me by Mr. William Talbot. 



10. One was taken at Hyde Park, Leeds, and shown to me, but 

 the date is not known. 



11. Finally, the latest in date is an example which flew on a 

 lady's dress, in Spring Street, Huddersfield. 



I have thus had reports of eleven specimens taken in this county, 

 seven of which (those numbered 2, 4, 5, 6, 7, 10 and 11) I have had 

 under my own examination. Four of the specimens (numbered 

 4, 6, 7 and 11) have been placed in the hands of Mr. McLachlauj 

 to whom I am much indebted for determining the species, which he 

 makes out to be Pachytylus cinerascens.* 



It is somewhat noteworthy that concurrently with this Yorkshire 

 visitation, only two examples have hitherto been recorded out of the 

 county, namely, the one recorded in the Ent. Mo. Mag. for 

 November, and one taken at Wells, Somerset, as recorded in 

 "Science Gossip" for December. 



It would be interesting to place on record any additional 

 specimens that have occurred, in order to justify conjecture as to 

 the line of migration. Can it be, as the remarkable preponderance of 

 Yorkshire examples would seem to indicate, that such line of migra- 

 tion was from the northern parts of Central Europe, by way of the 

 German Ocean and the Yorkshire Coast, and that the few southern 

 specimens were stragglers from the north ? I should be glad to see 

 or receive additional records, and intend to contribute a paper on the 

 subject to the "Naturalist" (published at Huddersfield) should 

 additional facts come to light. 



9, Sunny Bank Terrace, Leeds : 

 December 2nd, 1876. 



Locusts in Yorkshire. — By way of supplement to the above note, I may say, 

 tliat I hare heard of another Yorkshire specimen, which was taken on the Gth of 

 September " enjoying the beauties of Nature " in the cemetery at Scarborougli 

 (Scarb. Daily Post, Thursday, Sept. 7th, 187G). I have not seen this example. — 

 Id. : December 14/A, 1876. 



* It is generally acknowledged by Orthoptorists that there are two species confused under 

 tho nsivae oi I'achytylus viigratnrius, one of which should boar the familiar name, and the other 

 that of P. cinerafceiiK (Tab.). As I understand these species at this moment, the visitors to York- 

 shire arc the latter. There exists an idea that this breeds annually in certain parts of Northern 

 Europe [c. g., Belgium), whereas the former only appears occasionally.- -K McLacula.n.
