8. — BagouK liniosus G-yll. 



This is another easily-distinguished species, being of broad form, 

 with the thorax much rounded at the sides and narrowed behind ; the 

 elyti-a has very Lirge punctures on tlie striae, but these are not readily 

 seen, as the insect is nearly always very dii'ty. The tarsi are elongate. 

 The aedeagus is elongate with a narrow pointed tip, and the superior 

 appendages of the tegmen are quite small. 



The species appears to be widely distributed in the south-east of 

 England; it is not uncommon at Brockeuhurst. Sheppey (/. J. Walker, 

 G. C. Champion^ ; Tollesbury, Essex, v. '08 {W. Bevin^, in coll.

9. — BaqoKS argilJaceus (xyll. 



This insect is extremely variable in size. In fresh specimens it is 

 recognised at once by the peculiar glaze of the surface. The eighth 

 joint of the antennae is broader than usual, and the tarsi are definitely 

 5-jointed. 



The aedeagus bears a general resemblance to that of B. nodtd- 

 osus, but is without the prominent trigger arrangement, and the 

 basal callipers are more slender. I have examined only one 

 specimen. 



B. argiUacevs was described from the Caucasus, and we may be 

 permitted to doubt whether our English insect is really it. In this 

 country this species appears to l)e almost confined to the lower part of 

 the Thames Valley, and we are indebted to Mr. Champion and 

 Commander Walker for supplying our collections with it. 



It has been taken sparingly by MoncreafE in Portsea Island (Ent. 

 Ann., 1890, p. 106; Ent. Mo. Mag., Vol. VII, p. 154). 



ELMiDOMORrnus Cussac. 



This genus should, 1 think, be provisionally retained, as the 

 structure of the club of the antenna is quite distinct from that of all 

 other Bagoini, and is indeed remarkable for a Curculionid. 



The alteration of the name to Helmidomorphas, or to Helmintho- 

 inorpJms, cannot be accepted, as the change is that of the first letter ; 

 and moreover does not bring accord with Grecian orthography, 

 although this is its raison d'etre.
