This species is constant in form and coloration, and I am unable 

 to refer it to any of the published descriptions. It belongs to the 

 peeidiar insect Faixua, observable upon the marrains or burrows of our 

 sandy sea shores. I took four or five upon the sand-hills near Deal 

 two years ago, and considered them at that time as a coast variety of 

 alhifrons ( ? ). Having taken both sexes again this antumn in plenty 

 at Newton Buitows,* Freshwater Bay, Pembrol^eshire, and observing 

 that the larvse also constantly differ from those of alhifrons, I no longer 

 hesitate in regarding the species as new.

Occurrence of Silvanus hidentatiis, a species new to Britain. — I have taken, under 

 pine hark near Paisley, a single example of a Silvanus which Mr. D. Sharp informs 

 me is the hidentatus of Fabric'ma (Syst. El., i., 317, 28, Dermestes ; Erichs., Ins. 

 Dent., iii., 338, 3). 



It is half as large again as S. unidentatus, and more elongate and duller than 

 that species ; having, also, the anterior angles of the thorax much more distinctly 

 and sharply spined, and a short — but decided — spine on each side of the head, 

 behind the eyes. The thorax, moreover, is longer, and has two shallow longitudinal 

 grooves ; the joints of the antennae are longer ; and the tibiae are not dilated ex- 

 ternally and obliquely truncated, as in S. unidentatus. — Morris Young, 7, Old 

 Sneddon Street, Paisley, December, 1865. 



Observations on OfiorJiynchus fuscipes and 0. ambiguus, S(c. — Having for some 

 time suspected that we did not possess both O. tenebricosus and 0. fuscipes (in spite 

 of the plate accompanying the late Mr. Walton's paper on OtiorhyncJius in the 

 " Annals and Mag. of Nat. Hist."), and being unable to find British specimens 

 agreeing v/ith the description of the latter in Dr. Stierlin's admirable " Revision der 

 Europaischen Otiorhynchus— Arton (Berlin, 1861)," I am not surprised to find, from 

 an examination of types sent by Dr. Stierlin himself to the British Museum, that 

 the true 0. fuscipes is unhke anything that has come under my notice ; and I there- 

 fore think (on these and other grounds) that it has probably not as yet been 

 correctly recorded as indigenous to this country. Some examples representing 

 it in the British Collection of the Brit. Mus., have been pointed out to me as presented 

 by Walton, but they are all females of tenebricosus. That insect appears to vary 

 considerably, both sexually and individually, as to bulk, punctuation, and colour of 

 legs. Typically, it is oblong-ovate ; with the head and thorax very delicately coria- 

 ceous, the latter being narrow, and a little longer than broad ; with its elytra 

 obsolctely striated, thickly coi-iaceous, and adorned with sparing patches of grey 

 pubescence. The chief varieties appear to have the thorax closely punctulated, 



• This remote and unexplored locality, similar in character to the coast between Deal and 

 Sandwich has produced me another novelty this season, being a British form of the genus Tettigonietra, 

 beloniiinjr to the group Fulgorina, and not hitherto known as inhabiting this country. I obtaineit four 

 individuals, didering much iu colour, but two ot thein were eaten in the niglit time by a marauding 

 Forficula. The sj.ecies is not T. virfacens, Fab., nor atra, Hagenbach, nor piccolo, Burm., and is 

 perh:ii)s new : but at this distance from London I have not vet found the niean» of identifyins it.
