380 RHYNCHOPHORA. [Bafit. 



A. Thorax with round, rather closely set, 



punctures B. PICICORNIS, Marsh. 



(abrotani, Germ.) 



B. Thorax with somewhat oblong aud much 



more diffuse punctures B. LEPIDII, Germ. 



2. Interstices of elytra broader; thorax closely 



punctured ; body oval B. CHLOBIZANS, Germ. 



iii. Elytra black, with the apex broadly red . . . B. ANALIS, Ol. 

 II. Thorax and elytra covered with somewhat scanty, 



but very distinct, greyish scales B. SCOLOPACEA, Germ. 



B. laticollis, Marsh (picina, Germ., glabra, Munich Cat., nee 

 Herbst.). Oblong, comparatively broad, black, shining ; upper and 

 under surface glabrous ; rostrum rather thick, punctured ; thorax longer 

 than broad, sparingly and finely punctured, with a more or less distinct 

 smooth central line ; elytra with fine, obsoletely punctured, striae, inter- 

 stices with rows of punctures ; femora robust. L. 3|-4 mm. 



On species of Cruciferte ; at roots of Sisymbrium officinale ; the larva has been 

 observed in the stems of the cultivated cabbage ; very local ; London district, rare ; 

 Battersea and Southeud (Stephens); Charlton (S. Stevens); Suffolk; Deal; Folke- 

 stone (common) ; Rye; Shirley Warren, Southampton; Isle of Wight, Veutuor (one 

 specimen taken by myself on a wall); Portsmouth, abundant (J. J. Walker); Port- 

 land ; Mr. Monoreaff has found the species abundant at Southsea " in galled roots of 

 Sisymbrium officinale as many as fifty from one root July and August ; " the 

 species appears to be entirely confined to the Southern and South-Eastern counties. 



In Mr. "Waterhouse's catalogue Stephens' specimens, named by him as 

 23. artemisice, are referred to this species ; he expressly says, however 

 (Manual, p. 217), that they were taken at roots of Artemisia vulgaris, 

 whereas B. laticollis is attached to Cfuciferue ; the species are allied, 

 but cannot well be confounded, as the true B. artemisice of Herbst. has 

 the thorax coarsely and rather closely punctured, whereas in B. laticollis 

 the punctuation is fine, shallow and diffuse ; it is quite possible that the 

 former species may be found in Britain as it is widely distributed 

 throughout Northern Europe and Siberia. 



B. picicornis, Marsh (abrotani, Germ.). Oblong, black or blue- 

 black, with the elytra blue or greenish-blue ; rostrum about as long as 

 thorax, punctured ; thorax longer than broad, distinctly and rather 

 closely punctured, the punctures being round ; elytra with moderately 

 fine, but variable striae, interstices with rows of punctures; legs black. 

 L. 3-3f mm. 



Chalky places; on Reseda lutea; the larva lives at the base of the stalks and in 

 the roots; very local, but sometimes common where it occurs; Caterham, Mickleham, 

 Darenth Wood, Reigate, Gravesend, Maidstone, Eastry, Headley Lane, Riddlesdown, 

 &c. ; Chatham (in great profusion, Champion and J. J. Walker) ; Lowestoft ; 

 Kingsgate ; Folkestone (common) ; Portsmouth district ; Glanvilles Woottou ; 

 Cromer ; Brandon, Suffolk (common, J. J. WalKer). 



B. lepidii, Germ. Very like the preceding, but easily distinguished 

 by the punctuation of the thorax, which has the punctures larger, some-
