taken by myself, represents the results of a few days' collecting each spring and 

 early summer since 190fi. As I spent each summer vacation in the South of 

 England, I have had no opportunity to look for some of the species, especially 

 Fossors, which are at their best in the hottest days of July and August. On my 

 return to Liverpool each year in September, the sandhills at Wallasey were still 

 productive for a few species up to the end of the month. (Additions to Mr. 

 Gardner's list are indicated by a *). At Wallasey sandhills : — Pompilus pectinipex, 

 Diodontus tristia*, Gori/tes tumidus*, Oxyhehia mandibularis*, Crabro varius*, 

 Proxopis hrevicornis^* Andrena nigriceps, Dasi/poda hirtipes (a large colony near 

 the Grolf Club House), Ccelioxyx elongata, C. mandibularis; Chrysididag : — Cleptes 

 nitiduliis, Hedychridium minutum, H. integrum. At Alvanley, Cheshire : — Sphecodes 

 similis* (with Andrena fulvicrus ?), Andrena humilis. At Delamere : — Trypoxylon 

 figulus, Diodontus minutus, Passolcecus insignis*, Crabro tibialis (one ? near 

 Hatchmere pond), C. cetratus*, C. varius*, C. anxius*, C. pahnipes, and C. chrysos- 

 tomus, Halictus tumulorum, H. atricornis"', H. freygessneri* , Andrena humilis, 

 A. minutula*, A. coitana*, A. angustior, Nomada ferruginata, Bombiis jonellus ; 

 Chrysididx : — C. ignita and C. cyanea. — G. Arnold, 7, Canning Street, Liverpool :

Bassux Icetatorittn, Fab., $ , bred from Syrphus balteatus, De G. — On August 22nd 

 last, I collected about half a dozen pupae of Syrphus balteatus, He G , in the Thames 

 Marshes, and among the resulting imagines was an Ichneumon that Mr. Morley has 

 been good enough to name for me as Basstts lastatorius, Fab. Although this genus 

 is known to be parasitic on Diptera {cf. Mr. Morley's memoir in the Trans. Ent- 

 Soc. for 1905, p. 432), yet notices of parasites bred from Orders other than the 

 Lepidoptera appear so seldom, that the above-mentioned instance may be considered 

 worthy of record. With regard to this particular species, Mr. Morley informs me 

 that it is very common, but rarely bred.— H. W. Andrews, Shirley, Welling, Kent :

Dastjneura {Perrisia) strobi, Winn., in Perthshire. — In September 1906, 1 picked 

 up a few cones of the spruce fir (Picea excelsa) in a wood near Callander, Perthshire, 

 and, on tearing oif some of the scales, noticed at their bases a number of small white 

 cocoons. Three of the cones were placed in a glass-topped bos, and from time to 

 time sprinkled with water, and in the early part of the following summer it was 

 found that about thirty small midges belonging to the family Cecidomyidx had 

 emerged. On consulting Walker's British " Diptera," Vol. iii, (1856), it appeared to 

 me highly probable that I had re-discovered Cecidomyia strobi, Winn., in this 

 country. Specimens were accordingly sent to Mr. J. E. Collin, who thinks there can 

 be little doubt they are that insect. Walker says it " lives in the fallen cones of 

 Pinus abies," but gives no locality. Verrall relegated the species to the "reputed " 

 section in the first edition (1888) of his " List of British Diptera," and omitted it 

 altogether from the second edition (1901). In Collin's useful " List of the British 

 Cecidomyidse, arranged according to the views of recent authors," published in this 

 Magazine for 1901', it appears again among " species reputed as British." A few 

 small green Chalcids also emerged from the Callander cones along with the Ceci- 

 domyids. —WiJjIjIAM Evans, 38, Morningside Park, Edinburgh : December ith, 1908.
