The ($ is remarkable for the shape of the genital segment, which is 

 very large, and terminates in a blunt, gaping forceps, of which the extremi- 

 ties are slightly deflexed. The medial frontal carina is bifurcate at about 

 the height of the insertion of the antennce. The two exterior carinas are 

 straight and parallel to the eyes, after which they are slightly ap- 

 proximated, 



I have two ,$ and eight ? , obtained from Birch "Wood and the 

 neighbourhood of Esher. They are all brachypterous ; but one ? has 

 the hemelytra \ as long ae the abdomen, and rounded more narrowly at 

 the apex, thus presenting a transitional form.

EXTRACT FROM M. ALLARD'S PAPER ON SITONES, &c. 

 BY E. C. EYE. 

 (Contmued from page 208.) 

 I shall now notice the difterent species in the order in which 

 M. A Hard arranges them, and must refer those who require further in- 

 formation to the late Mr. Walton's paper on Sitona (ex. Ann. & Mag. 

 of Nat. Hist., 1844, p. 66 et seq.) ; to which, however, M. Allard does 

 not make any specific reference in his notes. 



The characters given in the table above at p. 206 will render it 

 unnecessary for me to give any lengthened description. 



S. GEiSETTS, Fab. This species varies considerably in size ; but its 

 greater length, elytra somewhat suddenly contracted at the apex, longi- 

 tudinally impressed thorax, and broad grey sutural band, at once dis- 

 tinguish it from all its British allies. It is abundant in sandy places 

 on the coast, especially in Lancashire, and is sometimes found inland. 

 According to M. Allard it lives on furze.* 



S. FLA.VESCENS, Marsham. This species closely resembles ^«mc^z- 

 collis, but is lighter in colour ; the elytra are broader and shorter, and 

 less regularly rounded at the extremity, being more contracted in their 

 lower third. The entire insect is also more closely and uniformly 

 clothed with silky scales. M. Allard gives as a diagnostic character the 

 presence of three white points on each side of the middle band of the 

 thorax, corresponding to two white analogous points on the vertex ; but 

 as puncticollis exhibits a similar marking (in a decidedly stronger de- 



* An allied sjiecies, S. gressorius, Gei'in., occurs generally in Europe, and may be found here. It 

 was re-united by Scliiinlierr to griseug, but differs in being larger, with the head less inclined, and the 

 eyes mnrp prominent ; the head and thorax together are lonfjer in proportion, and the latter has a 

 narron; straight, loneitudinal, white line, exactly in the middle. The punctuation of the thorax is 

 stronger, and the stripe of the elytra arc more evident.
