base of ihe fore wing, and a diffuse testaceous spot on the 

 slevnura beneath the wing; the abdomen is black above and 

 on the sides beneath, but testaceous in the middle beneath ; 

 the legs, including the coxas and tarsi, are ochraceous. Mr. 

 Healy possesses interesting particulars concerning the life- 

 history of this insect, which I tiust he will shortly make 

 known to the readers of the 'Entomologist.' — E. Neicmav. 



Allaiithus viduus, a new British Hymenopteron of the 

 Faviily Tenthredinid(c. — 1 had the good fortune to take 

 a single specimen of this insect, many years ago, in Darenth 

 Wood, in Kent, and it has remained unnamed until the pre- 

 sent month, when Mr. Smith, of the British Museum, kindly 

 supplied names for the present and the following species. 

 There is no cognate species with which to con)pare Allantus 

 viduus : the fore wings are opaque smoky brown ; the head, 

 thorax and abdomen intensely black, with the exception of 

 the 4th segment, which is white above : it is about the size 

 of A. zonatus. — Id. 



Allantus SclKBJferi, a vew British Hymenopteron of the 

 Family Tenthredinidm. — I took a single specimen of this 

 insect, also many years since, in Herefordshire, and, like the 

 previous one, it has remained unnamed. A. Zona and A. 

 Zonula are cognate British species : it resembles both of 

 these in size and the yellow base of the antenna; ; the fore 

 wings have a clouded costal margin, more especially towards 

 the tip ; the abdomen is black, with two yellow belts ; 

 the first is very narrow and near the base, the second 

 broader and beyond the middle ; the tip is also yellow : it 

 agrees with Zona and Zonula in size. — id. 



Platystoma Umbraritm, a new British Dipterori of the 

 Family Miiscidce. — A single specimen of this insect, which is 

 the Musca Umbrarum of Fabvicius' 'Species Insectorura,' ii. 

 450, 80, and the Platystoma Umbrarum of Meigen's ' Diptera,' 

 v. 391, pi. 53, fig. 22, has been taken in Gloucestershire : it 

 is a much larger and more showy insect than the common P. 

 Seminationis, which in other respects it a good deal resembles. 

 The specimen is now in the cabinet of the Entomological 

 Club.— /(/. 



Coccus Beckii, a vew British Hemipteron of the Family 

 Coccidcs. — My readers will recollect a most able and valuable 

 })aper, published in the ' Zoologist' (second series), by the late
