MeUgethes."] CLAVICORNIA. 253 



leaden reflection, clothed with thick grey pubescence, rather deeply and 

 thickly punctured; antennae yello w-brown, with the first joints lighter; 

 thorax twice as broad as long, narrower at base than base of elytra ; 

 legs reddish, anterior pair lighter ; anterior tibiae finely but rather 

 unevenly and irregularly toothed, the teeth being in some instances 

 fine and sharp, in others broader and blunter, the right and left tibiae 

 being occasionally different, and showing both these characteristics in 

 the same insect ; both sexes have a small excavation at the extremity of 

 the last abdominal segment. L. lj-2 mm. 



Ou various kinds of flowers and blossom ; common and generally distributed 

 throughout England and Wales ; Scotland, not uncommon, Solway, Forth, and 

 probably other districts ; Ireland, near Water ford, and probably general. 



BT. rotundicollis, Bris. Short oval, rather convex, leaden black ; 

 antennae light ; thorax about half as broad again as long, broadest about 

 the middle ; punctuation of thorax and elytra close, with fine but 

 distinct cross reticulation between punctures; in the two preceding 

 species the thorax is entirely smooth between punctures, and the elytra 

 are either smooth or show very faint traces of cross reticulation ; legs 

 reddish-yellow, anterior tibiae finely denticulate. This species at first 

 sight closely resembles M. picipes, and is often confounded with it ; 

 it is, however, readily distinguished from it by the rounder and some- 

 what dilated sides of thorax, emarginate forehead, closer punctuation, 

 and also by the plain cross reticulation between the punctures of the 

 thorax and elytra, and the finer denticulation of the anterior tibiae.

TNI. symphyti, Heer. Oval, convex, short in comparison with its 

 breadth, smooth and shining, with scarcely visible scanty dark pubes- 

 cence ; colour violet or greenish-blue ; antennan light, except club, 

 which is somewhat darker ; thorax a third broader than long, more 

 closely and deeply punctured than elytra, interstices quite smooth ; 

 elytra rather strongly and somewhat diffusely punctured, with plain 

 cross reticulation between punctures ; legs yellowish or reddish-yellow, 

 anterior tibiae finely, sharply, and evenly denticulate ; male with a deep 

 longitudinal impression on the hinder half of the metasternum, with a 

 tubercle on each side, and a smaller one in the middle of the posterior 

 margin. L. 2| mm. 



On Symphytum officinale, but by no means confined to this plant ; in fact, more of 

 our British specimens have been taken on Agraphis nutans, and it has occurred on 

 Taraxacum; rare; Mickleham, Caterham, St. Mary Cray (Champion); Chatham; 

 Darenth Wood ; Shiere (Capron) ; Henley (Power) ; Amberley (Walker) ; Bowdon,
