BIBLIOGEAPHICAL AND NOMENCLATORIAL NOTES ON HEMIPTERA. 13 



reimpression in 1830, of which there is a copy at the British 

 Museum. It does not, I think, differ from the first edition, that 

 is, as regards the Hemiptera. 



I have recently acquired an American edition in eighteen 

 volumes, pubhshed at Philadelphia, which is said to be " cor- 

 rected and imi)roved by the addition of numerous articles 

 relative to the institutions of the American Continent," but I 

 cannot see that the part dealing with " Hemiptera " is altered. 

 As I have not seen it previously referred to, and as it is not 

 apparently in the Library of the United States Department of 

 Agriculture,* it is as well to refer to it now. "Entomology" is 

 discussed in vol. viii. pp. 646-758, and the Hemiptera on pp. 709- 

 715. 1832 is the date of the entire publication. 



IV. 



In the ' Entomologist ' for 1905, p. 307, I published what 

 information I had then in my possession regarding the dates of 

 publication of Burmeister's 'Genera Insectorum." I now find 

 further information in the ' Zeitschrift fiir die Entomologie,' i. 

 298-9 (1839). 



Of the parts of the dates of which I was ignorant, it is stated 

 that Bythoscopus, Eurymela, Acocephalus, and Lystr (sic !) were 

 published in 1838, fascs. 1 and 2 ; so that the correct dates are 

 as follows, for Hemiptera : — 



Hefts 1 and 2 (1838) : Bythoscopus (no. 10) ; Eurymela 

 (no. 17) ; Acocephalus (no. 11) ; Lijstra (no. 20) [Ed. 2, 1840-6] ; 

 probably completing heft 1 ; Selenocephalus (no. 12) ; Coelidia 

 (no. 15) ; Eupelix (no. 6) ; Jassus (no. 14). 



Heft 3 (1838) : Ulopa (no. 3) ; Dorydium (no. 5) ; Cephalehts 

 (no. 4) ; Ledra (no. 9). 



Heft 4 (1838) : Gypo7ia (no. 16) ; Xerophlcea (no. 8). 



Heft 5 (1840) : Paropia (no. 7). 



Heft 6 or 7 (1841) : Typhlocyba (no. 13). 



Heft 8 (1845) : Fulgora (no. 18) [with subgenus Pyrops, 

 no. 19 in Index] .

(a) Distant (1906, Cat. Hom. i. 180) cites Tettigonia tibialis, 

 Panzer, as a species (unseen by him) of Pauropsalta. This may 

 be (I have not Panzer's work complete), but Tettigetta tibialis, 

 Kolenati, given as a synonym, is certainly not, as the figure 

 clearly shows six apical cells in the wing. 



(b) Distant (p. 167) has omitted Ctcadetta prasina var. cau-
