RHYNCHOPHORA.

distributed in Europe, especially in the north ; it lives on Pinus tylr^- 

 ?m,and the larva undergoes its transformations between two pine-needles, 

 which are joined together and are by the presence of the insect arrested 

 in their development ; the species may be known by its elongate and 

 subparallel form and short stout legs, and by having the penultimate 

 joint of the tarsi very strongly bilobed ; the rostrum is long, slender 

 and curved, and the antennae are inserted behind its centre ; in Britain 

 the species is confined to the Highland districts of Scotland, in which it 

 is very local. 



B. pineti, Payk. (indiffcna, Herbst.). Elongate, linear, subparallel, 

 clothed with scanty but rather coarse pale pubescence, which is stronger 

 on the head and thorax, rather dull ; head and thorax dark, elytra red- 

 dish testaceous ; rostrum shining, black, sometimes reddish-brown ; 

 antennae red ; eyes flat, somewhat widely separated on vertex ; thorax 

 transverse, slightly narrowed in front, shallowly and not closely punc- 

 tured ; scutellum with whitish hairs ; elytra very long, with strongly 

 punctured striae an-:l narrow interstices, which are furnished with rows of 

 short hairs ; legs short and stout, red, tarsi broad ; intermediate coxae 

 contiguous. L. 2|-2|- mm. 



On young Scotch Fir; very local; Tay, Dee and Moray districts (Braemar, A vie-, 

 more, Eannoch, &c. (Sharp, Champion and others) ) ; the species was first taken by 

 Turner in 1860, who said he had beaten his first three specimens off birch. 



CIONINA. 



This tribe is here regarded as including both Clonus and Nanophyes ; 

 it is characterized by the formation of the second, third and fourth ven- 

 tral segments of the abdomen, which are produced into a tooth at apex 

 near margin ; the antennae are inserted in front of the middle of the 

 rostrum and have the funiculus five-jointed and the club, as a rule, 

 large ; the anterior coxae are contiguous and the posterior coxae are 

 distant ; the tarsal claws are connate ; the transformations of Clonus 

 closely resemble those of Hypera, and will be further noticed. 



In the formation of the trochanters the genus Nanophyes resembles 

 Apion, and on this ground is classed by Bedel with the latter genus as a 

 separate sub-family Apiidae ; the relations, however, of Nanophyes to 

 Cionus are so strong, and its differences from Apion, apart from the 

 trochanters, so great, that it can hardly be separated from the position 

 it has usually occupied among the Cionina, although it may, perhaps, 

 be in some respects regarded as a transitionary genus. 



I. Femora not attaining coxae ; trochanters long; scutellum 



scarcely visible ; thorax comparatively large, not much 



narrower at base than elytra ; size small NiyoPHTES, Schonh. 



II. Femora attaining coxae; trochanters short; scutellum 

 large and conspicuous; thorn x small, much narrower at 



Lase than elytra, which are almost subglobose . . . CIONPS, Clairv.
