very closely allied. Lyprus, "uliich is very attenuate^ 

 and spider-like about the IcgSj has but six joints to the 

 funiculus. 



lu Litodactylus and its allies, all more or less attached 

 to water-plants (some even existing under water, in 

 Myriophyllum) , the rostrum is short and thick, the scu- 

 tellum inconspicuous, and the eyes large and promi- 

 nent ; and in Ceuthorhynchus, a very extensive genus of 

 small convex species, the rostrum is long, arched, and 

 slender, and received in repose only between the front 

 pair of legs, there being no groove for it in the meso- 

 sternura. Some of this genus (which is divided into 

 two sections, the first having the femora simple beneath, 

 whilst in the second they are toothed) are prettily varie- 

 gated with Avhite scales ; others are metallic blue, or set 

 sparingly with short stiff bristles. 



Many of them are very abundant, and do considerable 

 damage to culinary vegetables, either — as perfect insects 

 — by piercing holes in them, or — as larvie — by forming 

 gall -like excrescences on their roots. As is frequently 

 the case, there is another genus [Ceuthorkynchideus) , 

 closely resembling this in which there are six instead of 

 seven joints to the funiculus. 



The CioNiDjj have the antennae ten- or nine-jointed, 

 short, the funiculus composed of five joints, and the club 

 of three or four. They ai'e all small ; and (except Me- 

 cinus, which is elongate and cylindrical) " squat " and 

 rounded. 



The species of Cionus are all beautifully variegated ; 

 they frequent Verbascum and its allies, often in great 

 numbers, the different species sometimes occurring in 

 company. Their larva?, which are small, convex, and 

 spotted, devour the entire parenchyma of the leaves, but
