patch at the base of the suture (the oblique streak running down 

 from the shoulder being altogether absent), &c. From A. genistcB it 

 may be known by the stronger rostral tooth, the more dilated pro- 

 thorax, &c. A. monticoln, Schilsky (for specimens of which I am 

 indebted to Herr J. Schilsky and Dr. J. Daniel), and A. difficile, 

 Herbst, are still more closely related forms, but as they are not found 

 in England, it is not necessary to call further attention to them. 



The present species is not uncommon at Chattenden, Kent, on 

 Genista tinctoria. It was first taken there by myself on September 

 I5th, 1872, and by Mr. Walker in the following year. He found it 

 in numbers at the same locality on July 7th, 1894.* Four members 

 of the genus have previously been recorded as attached to the same 

 plant, viz., genistce, elongatuUun, flavofemoratum, and difficile {cf. 

 Schilsky, op. cit., xliii, p. cii).

OXYPOBA METATARSALIS, TaoMS., AS A NEW BRITISH SPECIES. 

 BY THE EEV. H. S. GORHAM, F.Z.S. 



While examining some siftiugs from a mole's nest at Mathon 

 with Mr. Tomlin on January 21st last, I was struck by a few OxypodcB 

 which had very much the appearance of O. vittata, but seemed rather 

 fine examples if they were that species. 



These are O. metatarsalis, Thomson (Skand. Col, ix, p. 247), an 

 addition to the British List, unless they should prove to be identical 

 with an example taken in Scotland by Dr. Sharp, and recorded by him 

 as 0. longipes. Considering the difference in locality and the peculiar 

 habitat, this seems very doubtful. 



O. metatarsalis is distinguished at once from both 0. vittata and 

 all the large species at the head of the genus by the structure of the 

 tarsi, especially the hind tarsi. These in O. metatarsalis appear much 

 longer than in the preceding species, owing to their second joint being 

 not much shorter than the first ; whereas in those species the first 

 joint is three times longer than the second. Other differences exist : 

 the antennae are longer and thinner, the legs are more infuscate (in 

 O. vittata they are clear yellow), the abdomen is quite black, except
