Differs as follows from T. bipunctatus : — form less robust, frons (seen from 

 above) produced somewhat between the antennae. Pronotum flatter, with the median 

 ridge but slightly elevated, and that chiefly anteriorly, with the process reaching 

 considerably beyond the posterior knees. Wings as long as the process of the pro- 

 notum. Posterior femora more slender. Length, 10 — 13 mm. 



Tbis species will also, I tbink, be found fairly common. I took it 

 plentifully at tbe end of September, 1887, on a landslip near Cbar- 

 moutb, Dorsetsbire (vide Proc. Ent. Soc. Loud., 1887, p. 50). Sweeping 

 seems to be tbe best method of taking tbe species of Tettix.

On breeding Deilephila galii. — It is usual, I believe, to force the pupae of this 

 insect, but it would seem that this may in some cases very well be dispensed with. 



Two gentlemen, who last year took pupse near Aldborough, Suffolk, and did not 

 force them, send me the following as the result of their experience : — One, N. F. 

 Hele, Esq., F.C.S., of Aldborough, had about twenty pupae ; the other, the Eev. R. 

 Peek, Rector of Swefling, had fourteen pupae. From the twenty pupae, thirteen 

 moths emerged in June and July. Mr. Hele writes : " I kept the pupae in sand, 

 covered with moss, in a cool room ; there was no forcing whatever." Of the four- 

 teen pupae, two were ichneumoned, one produced a cripple, and nine proved perfect ; 

 they emerged during the last fortnight in June, and the first week in July. Mr. 

 Peek says, " I kept the pupae in an aquarium on their original sand from the sea- 

 shore, covered over with moss, and the only forcing I used was a tepid bath once a 

 fortnight, or when they looked dry." Mr. Hele adds, that about 150 larvae fell to 

 the lot of himself and two friends, but that when, in the early part of October, 

 there were some frosty mornings, the mortality among the larvae was great. 



From the two ichneumoned pupae mentioned above, three very handsome insects 

 were bred : from one, Trogus exaltatorius, Panz., from the other, two specimens of 

 Amblyteles proteus, Christ. These are among the largest British Ichneumons, and 

 are both well-known parasites on the Sphingidce ; but I do not know whether they 

 have been recorded as bred from D. galii. — E. N. Bloomfield, Guestling : October

Pterophorus isodactylus in South Dorset. — On August 30th last, I had the 

 pleasure of taking three specimens — two much worn, but one in magnificent con- 

 dition — of this uncommon plume-moth in a water-meadow in the neighbourhood of 

 Wareham. The only previous record of its occurrence in this county is as follows : —
