four posterior femora, as well as all the tibiae, pale. Not common. I found several 

 specimens in the neighbourhood of Edinburgh in August, 1875, and have received 

 it from Mr. B. Cooke, of Southport. 



H. tibiaria, Bond. 



This peculiar species bears a very strong general resemblance to H. cardui in 

 the colour, shape, and markings of the thorax and abdomen. It differs in having 

 the arista rather longer haired ; the tibiae all piceous or testaceous, and above all in 

 having the abdomen furnished in the middle of its ventral surface with a tuft of 

 black hairs, so long that it extends in a curved direction backwards as far as the 

 apex of the abdomen, and even sometimes beyond it. 



Length, 7 mm. (about 3£ lin.). 



The female is unknown. Not common. I have captured it at Thorpe Arch, near 



York. This species is probably identical with the H. penicillaris of Rondani, which 



I have not seen ; the only difference between them appears to be that the legs are 



wholly black in the latter.

DESCRIPTION OF A NEW SPECIES OF LIBURXIA. 

 BY JOHN SCOTT. 



Of finding new Libumiw there appears to be no end ; their 

 numbers increase so rapidly. In the same lot from which the under- 

 mentioned has been extracted, I believe there are at least two other 

 new species. My collection being for comparison of no use, I, as a 

 rule, when at a loss in this group, submit the doubtful example to 

 M. Lethierry, the fortunate possessor of Dr. Fieber's collection, for 

 identification. The following is a portion of the result of his kind 

 investigation at this time. 



LlBURNIA INSIGNIS, 71. Sp. 



S ■ Brachypterous. Pale yellowish. Crotcn about as broad as long, not 

 projecting beyond the front of the eyes. Elytra reaching to about the middle of 

 the abdomen, apical margin flatly rounded. Abdomen pitchy-black, posterior margin 

 of the terminal segment broadly white ; genital segment, viewed from the side, pro- 

 duced into an angular form posteriorly, and having a short, curved, acute tooth at 

 the lower extremity. 



Head : crown broad ; breadth about equal to the length, basal fovea? distinct 

 but not deep, the triangular space in front enclosed between the keels barely ex- 

 tending to the frons, anterior margin slightly convex, not projecting beyond the 

 front of the eyes : face slightly brownish -yellow, broad, slightly narrowed between 

 the eyes, central keel distinct but not prominent : antenna yellow. 



Pronotum : posterior margin flatly concave across the scutellum, side keels short, 

 somewhat indistinct, disc on each side of the centre somewhat depressed. Scutellum : 

 keels distinct, somewhat acute. Elytra reaching to about the middle of the abdomen, 

 margin at the apex flatly rounded, nerves fine, not granulated. Legs yellow: thighs 

 at the base fuscous. Abdomen pitchy-black, shining, with a large yellow or brownish-
