Supplementary note on XylopTiagus ater and X. cinctus. — In my notes on these 

 species (E. M. M., xiii, 160), I overlooked certain articles which are referred to in 

 the Zoological Record, and which I have not yet had an opportunity of seeing. 

 Daraianitsch (Yerh. zool.-bot. G-es. in Wien, xviii, 117) found the larva of X. ater, 

 under alder bark, and describes its metamorphoses. Frauenfeld {I. c. 166) con- 

 firms Drcwsen's statement that the larva is carnivorous. The transformations of X. 

 cinctus are re-described and figured by Ferris (Ann. Soc. Ent. Fran., 4e serie, x, 

 202, &c.), who found the larva in the galleries of Tomicus stenographiis in Finns 

 maritimus. He thinks it feeds on the " fi'ass " of the beetle, and is occasionally 

 carnivorous. — F. Buchanan White, Perth : December 23rd, 1876. 



Locusts in Yorkshire. — lu addition to those recorded in the E. M. M., for 

 January, by myself, I will add that Mr. N. F. Dobree, of Beverley, informs me that 

 two were taken at Beverley during the latter half of August, which he saw alive. 

 He states that the length was fully 2f inches, and the colour grass-green, while that 

 of a smaller specimen, taken at Spurn (the extreme south-east point of the county), 

 during the first days of September, is a more yellow shade of green. He also informs 

 me, on the trustworthy authority of Mr. Philip Lawton, of Easington, four miles 

 from Spum, that eight specimens were taken there during the second week of 

 September, three of which are in Mr. Lawton's possession. Mr. Lawton also adds 

 that two were brought to him in 1875, and that locusts are of frequent occurrence 

 in the summer. Can it be that locusts breed in the British Islands ? they seem to 

 occur on some portion of our coasts or inland nearly every year. I have seen records 

 of their abundant occurrence at or near Spurn Point in 1842, 1846, 1858, 1859, 

 1875, and 1876. — Wm. Denison Roebuck, Leeds : January 15th, 1877. 



Locusts in Yorkshire. — I have had some correspondence with my friend Baron 

 De Selys-Longchamps respecting the species of Pachytyliis to which the examples 

 noticed in our last No. should be referred. He agrees with me that they are certainly 

 P. cinerascens, and adds, that he is persuaded that this species breeds regularly in 

 Britain (as, according to him, it does in Belgium). I do not share this opinion ; but 

 it is probable that the greater part of those taken in Britain are cinerascens. — R. 

 McLachlan, Lewishani : 30th December, 1876. 



Change of generic name fParthenos, Huhn.). — I propose to substitute for the 

 above generic name, occurring in all the American lists of Heterocera, the generic 

 name Catocalirrhis, reading thus : — 



Catocalierhis, W. V. Andrews. 

 nnbilvs, Hiibn. 



My reason for this is, that Parthenos is also used by Hiibncr for a genus in 

 Rhopalocera (Verz. bek. Schmett., 38, 1816) ; and, without reference to the law of 

 priority, which docs not apply in a case like this, where the same name is used by an 

 author for two difPerent genera, I think it desirable to suppress the generic name 

 covering the fewest species ; this, on the ground of convenience. — W. V. Andrews, 

 36, Boerum Place, Brooklyn, New York : December 26th, 1876. 



[It is possible that the law of priority docs apply in this case, as Iliibner's 

 " Verzeichniss " was in all probability published in sheets, in which case the Rho- 

 palocerous genus would stand by chite. Hiibner put only one species in it, however ; 

 so it is difficult to see how the idea of suppressing the name covering the fewest 

 species can apply : Boisduval, moreover, has already re-named this first genus 

 Mimetra, but without special reason, just as he re-named all the otbers that he took 

 up.- The species of the Heterocerous Parthenos, by the way, is nubilis, and not 

 nubilus. — Eds.]
