acknowledged that Dahlbora's larva and his had the same number of 

 those appendages. It is also worthy of remark, as at p. 572, that the 

 French author, who appears to read neither German nor English, 

 seems to consider that during the interval of time between Reaumur 

 and himself (1740 — 1847) nobody has said a word respecting the loss 

 of colour and markings undergone by the larvae of sawflies at their 

 last change of skin. 



On the other hand, T quite agree with Leon Dufour that there is no 

 reason to consider Dahlbom's Nematus grossulariatus as a distinct 

 species from his Grossulariae. The larvae of the two species, as well 

 as the perfect insects, were as like as two peas, the only difference 

 being that the first pupized on the branches and made a simple 

 cocoon. 



P.S. Since the above was written in the original, the following has 

 been received from the author: — Nematus ventricosus, King. There 

 was an incredible number of these larvae in I860. From observations 

 made by Dr. Witterwaal at Utrecht, and by myself at Leyden, there 

 seems to be no doubt that the first brood in May attacked exclusively 

 the leaves of the gooseberry, some of the bushes being quite stripped, 

 and that the second generation, appearing in July, principally con- 

 fined itself to the currant, but small numbers having been seen 

 on the gooseberry. I observed this myself in a garden where the 

 two plants were growing intermixed; both larvae and imagos were 

 decidedly of but one species. From this second brood I reared the 

 parasite Campoplex argentatus, var., and a Tachina. 



Notice of two Species of Coleoptera new to Britain. — While working out my speci- 

 mens of Oxytelus, some time ago, 1 found a series of specimens agreeing with each 

 other and differing from any species I had seen described ; upon the appearance of 

 Dr. Schautn's new edition of his Catalogue, I thought raj species would prove to be 

 O. maritimus, as in fact it does. It was taken on the Somersetshire coast under sea- 

 weed, and was tolerably abundant. It resembles O. inustus somewhat closely, but is 

 easily distinguished by the testaceous antennae and the more scattered punctuation. 

 I should also like to call the attention of entomologists to the genus Chalcoides, of 

 which we have at least one more species than is recorded, viz. C. Chloris, not un- 

 common on sallows. It is nearly allied to C. versicolor, but is of an unicolorous 

 green, and has only four joints at the base of the antennae pale, instead of five, as in 

 C. versicolor. The male also furnishes a decisive character in the shape of the 

 cedeagus, which is never emarginate as in C. versicolor. — G, R. Crotch; St. John's
