Entomologists looking for the ? may perhaps obtain it by collecting snailless shells 

 from moist situations, at this season — the developed ? being most likely not more 

 attached to the living snail, than the male, at maturity — at all events, not until the 

 time of oviposition ; but yet it may, as my observation leads me to think, seek the 

 untenanted shell as a protection to its soft body — a protection not required by the 

 more favoured and winged male. We have an instance somewhat similar in the 

 Hermit Crab. The scarcity of the $ Drilus in British cabinets does not surprise 

 me ; as, had I not caught the glimpse of her ladyship's tail, I shoidd have neglected 

 the shell as empty and useless. I do not think this shell had had a snail in it this 

 year. However, it is carefully preserved, and doubtless some conchologist will be able 

 to decide on this point. — George Lewis, West Terrace, Folkestone : 9th Jidy, 1873. 



Capture in Noi'thiimberland of a Saw-fiy new to Britain. — Among other insects 

 taken in the vicinity of Wooler by my old friend Mr. James Hardy, is a specimen 

 of Strongylogaster fiUcis, Klug, a species not hitherto recorded as a native ; it is a 

 male {Tenthredo carinata, Klug, Hartig), and was captured on the 12th June last. 

 Thomson (HjTiienoptera Scandinaviae, i, 242) adopts Klug's name for the female 

 (JiUcis) as that of the species, but without giving any reason for, doing so. It would 

 appear to be rather a rare insect, as Hartig (Blatt- und Holzwespen, 299) says that it 

 has occurred to him but i-arely, in June, on ferns. — T. J. Bold, Long Benton, New-

Occurrence of Poecilosoma pulverata, Retz., a Saw fig new to Britain. — During 

 a visit paid to Rannoch in June, I captured among the alders at Ball three specimens 

 of Poecilosoma pulverata, Eetz. (ohesa, Klug), which, as far as I am aware, has not 

 been added to the British species before. It was also met with near Blair 

 Athole, and I received a specimen from Dr. Wliite, which had been taken by him at 

 Bi'aemar. Its life history has been well described by De Greer in his Memoires, ii, 

 242, tab. 34, figs. 20— 25.— P. Cameron, Jun., 13G, West Graham Street, Glasgow : 

 June, 1873. 



[I have this insect from Eannoch, Dumfries, and the New Forest, and it is also 

 in the British collection in the British Museum, but appears not to have been hitlierto 

 recorded as native. It is very closely allied to ISmphytus ochropodus, Klug (for 

 which Stephens formed his genus Heterarthrus), notwithstanding that this latter has 

 only three sub-marginal cellules, owing to the first veinlet being absent, a very arti- 

 ficial character. — R. McLachlan.] 



Lithosia stramincola and griseola proved to he only varieties of one species. — 

 From eggs of Lithosia stramineola, kindly sent to me in August last by Mr. C G. 

 Barrett, I have lately succeeded in rearing four perfect insects, one male and three 

 females. Two of the females are yellow all over, one of them having its wings somewhat 

 clouded with greg ; and the male is grey all over, in fact, a true griseola. 



The correctness, therefore, of M. Guenee's opinion as to the identity of these 

 two forms is completely established, and stramineola must take the position which 

 he assigns to it, of being a variety oi griseola. I may say, also, that I can corroborate 

 all that M. Guen^e states of the larva in his letter to Mr. Doubleday, given in The 

 Zoologist for 1863, p. 8396 ; I treated my late brood just in the same manner as 

 tliat which I had in 1867 — 8 (see Ent. Mo. Mag., voj. v, p. 110). but my success has 

 not been so great as it was then, for I have not reared a quarter so juany moths. —
