specimens sent me from time to time for determination, identical with those of 

 England, and pinned with English pins, I am convinced that there must be great care, 

 lessness or deception on some side. We have enough species legitimately introduced 

 without bringing dead ones on pins." — Yerj good, Dr. Horn ! — But I am sure my 

 talented friend will forgive me for suspecting that, notwithstanding the rather tall tone 

 of his note, the deception may be with him ; and for the following reasons, viz. : that 

 the species does not occur in Bi'itain, a fortiori not in "England," and that the British 

 pin is evidence rather of a Canadian, than a continental-European, origin for the 

 " number of specimens ;" most Canadian collectors having formerly used British 

 pins. Next, that the limited distribution of the species in the old world and the 

 area in which it there occurs render it very probable that it exists also in North 

 America, though perhaps not descending so far to the south as to reach the United 

 States. The evidence of the existence of this remarkable species in North America 

 is, however, undoubtedly in need of confirmation. Perhaps some Canadian reader 

 of this magazine may be kind enough to give us a note on the point. — D. ShAEP

Notes on some species of British Hemiptera. — Peritroclius nuiilus, Fall. {c.f. 

 E. M. M., vol. xi, 267, and xv, 202). — I took a single example out of a tuft of grass 

 at the side of a path in Darenth Wood on 2nd October last. 



Pilophorns perplexus, Doug, and Scott. — At the beginning of July, among a 

 number of Formica ftisca,! saw some larvse of this species running up and down the 

 stem of an apple tree ; before the end of the month there were adults in the same 

 situation, and shortly afterwards I found them on the various trees of the garden, 

 where no larvae had been seen. 



The genus Diceanonetjea, or, as Hardy imperfectly wrote it, " Dikeaneuea," 

 appears not to be accepted on the continent, vice Notus, Fieb. (1866), although it is 

 identical and dates from 1850 (Trans. Tyneside Nat. Field Club, i, 423). The char- 

 acter of the neuration of the type, D. variata, is well expressed — •" Wings with the 

 upper nerves disposed in two forks, the upper opening inwardly on the base, the 2nd 

 shorter-pronged, outwardly on the apex." This configuration is excellently repre- 

 sented for the same species (Notus aridellus, Sahib.) by J. Sahlberg in the " Not. 

 Fenn.," xii, tab. i, fig. 21. The " forks " lie reversed as to each other, the parallel 

 prongs resembling those of musical tuning-forks, and are connected by a short trans- 

 verse nervule, which Hardy appears to have overlooked, as he could easily do, for it 

 is slight and mostly transparent : — he says, respecting it, "no apjmrent cross nerve." 



Dicranoneura variata, Hardy.— Of this very common species the colour of the 

 elytra varies from pale green to dark green, sometimes with a reddish flush. Mr. G-. 

 Norman lately sent some examples, taken by him at Forres, of which the greater 

 portion of the corium of the elytra was of a deep orange-red, thus making the specific 

 name very appropriate. This deep red colour does not appear on southern examples. 



Typhlocyha blandula, Eossi. — On the 23rd March last, at West Wickham Wood, 

 T found this species abundant on the green leaves of brambles. It is to be noticed, 

 that, however much the red colour of the elytra varies in intensity, the portion next 

 the costa is always clear and pale ; and that in the posterior tarsi of the ^ the last 

 joint only is black on the posterior half, while in the $ this joint is pale like the others.
