in Scotland, running in muddy places on the banks of rivers and streams, whilst 

 the latter occurs very rarely in England and Scotland, in Sphagnum. M. Aube's 

 glauca must, therefore, be added to our list, and M. elongata, Ktz., must be sup- 

 pressed. It may readily be distinguished from elongata, Matthews, by its smaller 

 size and darker colour, the palpi and legs especially being nearly black. — E. C. Eye,

Note on Phytonomus Julinii, Sahlberg. — M. Capiomont, in his recent ' Eevision 

 des Hyperides,' Ann. de la Soc. Ent. de France, 1868, vol. 8, p. 153, considers this 

 insect (which he, apparently with correctness, indentifies with the Hypera alternans 

 of Stephens) as decidedly distinct from P. Pollux, of which the late Mr. Walton 

 thought it to be a mere color variety. The addition of P. Julinii to our lists as a 

 good species has already been made, and on the authority of M. Capiomont ; but I 

 have thought it may not be altogether useless if I were to enumerate the characters 

 upon which that gentleman proposes to separate it from P. Pollux (four species 

 intervene between them in the work above quoted), as the insect is not uncommon 

 here (" assez commun en France," p. 152 ; " assez rare en France," p. 155), and 

 observers in different parts of the kingdom may be more fortunate than I, in finding 

 those characters sufficiently constant. 



M. Capiomont, when treating of P. Julinii (p. 155), after stating generally 

 that the pattern of its elytra, which are regularly and alternately lineated with 

 dark and light scales, is sufficient to separate it from all the species allied to it, and 

 is constantly the same, remarks that its form is rather different from that of P. 

 Pollux, which, and especially its male, is always more slender, its female being 

 more elongate. He states also that the striae of the elytra in P. Julinii are better 

 denned, the absolute punctures being wider, squarer, and better marked; the inter- 

 stices are more regularly shagreened, and have coarser scales ; and the thorax is 

 always less cylindrical. 



At p. 160, treating of P. Pollux, and commencing with the somewhat contra- 

 dictory statement that it has exactly the form of P. Julinii, he enumerates (in 

 addition to the above characters) the following points of discrepancy : — the rostrum 

 is a little longer in Pollux, $ , and the depression between the eyes is generally 

 better marked ; the thorax is less rugulosely punctured (though, as he admits, there 

 are exceptions on this point) ; the colours of the elytra, instead of being separated 

 by distinct intervals, are confused, so that they are uniformly variegated with 

 grey and black, always excepting the 3rd and 7th interstices, which are variegated 

 with white for a greater or less portion of their length ; the punctures of the striae 

 are more uneven ; the interstices are more shagreened (in Julinii more regularly 

 shagreened, p. 155) ; and the female of Pollux is never so ventricose as the 

 same sex of Julinii. M. Capiomont finally notes that, among the numerous speci- 

 mens of Pollux that have come under his observation, he has never seen a single 

 individual with the elytra almost lineated as in Julinii, or even with the coloration 

 so disposed as to permit the suspicion of a passage from one species to the other. 

 But he specifies a var. of Pollux having dark elytra with the 3rd and 7th interstices 

 almost entirely, and the bases of some of the other interstices, whitish ; and 

 admits connections between this var. and the type.
