joints long, successively decreasing in length. Antennae of the female 

 subclavate, not more than half the length of the body. Thorax 

 elongated, of the usual structure ; meta-thorax well developed, tri- 

 carinate, with two slight ridges diverging obliquely hindward from the 

 middle keel. Petiole extremely short. Abdomen of the male sub-fusi- 

 form, smooth, concave above, except towards the tip, very little shorter 

 and narrower than the thorax, with a slight small luteous discal streak 

 before the middle ; abdomen of the female elongate-oval, a little broader 

 but hardly longer than the thorax, keeled beneath for fully half the 

 length from the base, slightly ascending from the end of the keel to the 

 tip ; first segment long, second and third short, fourth, fifth, and sixth 

 moderate, the apical small, conical. Legs luteous ; tarsi with black 

 tips ; hind femora of the male partly blackish exteriorly. Wings 

 limpid ; veins brownish ; humerus nearly twice the length of the ulna ; 

 radius shorter than the ulna ; stigma black. Length of the body, 3-3^ 

 lines ; of the wings 4-4| lines. 



This species belongs to my 25th section of Pteromalus (see Ent. 

 Mag., vol. 3, p. 465.) 



Besides the above, Mr. Winter was the first who captured Polemon 

 liparcB, which I mentioned as belonging to an apparently undes- 

 cribed genus ; and he has also made the noteworthy observation that 

 the yellow larva of Ghlorops tarsata feeds in April and May in the folds 

 of the reed cane, in companies of four or five together ; and that it 

 changes to pupa soon after the middle of May, and remains in that 

 state about forty days.

Note on Sitones cinerascens, recorded as British by M. Allard. — In M. AUard's 

 " Classification du genre Sitones " (a concluding notice of which, as regards the 

 British species, &c., will appear in our next number), S. cinerascens, Schon. (gen. 

 vi., p. 256), is stated to occur in England, on the authority of the collection of the 

 French Museum. This species is stated to be very closely allied to S. camhricus, 

 having the same structure and size, and to be distinguished from that insect princi- j 

 pally by the cinereous silky pubescence on its upper surface. This pubescence is 

 closer and longer than in S. camhricus, and often (not ahcays) prevents the punctu- 

 ation of the insect from being seen : the punctuation itself, moreover, is a little j 

 weaker ; the head is less furrowed, and the elytra seem to be a little longer. The j 

 antenna) appear to be more ferruginous, and the entire insect has an uniformly ■ 

 lighter appearance. 



It will be observed that the differences between these two insects are 

 extremely minute. — E. C. Ryk, 284, King's Road, Chelsea.
