BriUsh Species of Homalota. 121 



great as their breadth. Abdomen black, shining ; seg- 

 ments two to four pretty finely and thickly punctured, 

 fifth segment more sparingly punctured, sixth nearly 

 impunctate ; the extreme apex obscurel}^ pitchy. Legs 

 pitchy-testaceous . 



In the male the under plate of the seventh abdominal 

 segment is much produced, narrowed towards the apex ; 

 the apex is not pointed, but formed by the meeting of 

 two gentle curves. 



This species is generally distributed in England and 

 Scotland. It is fond of very wet places, in marshes, and 

 on the banks of streams and rivers. 



Ohs. — Thomson^s H. hygrohia is said to be this species 

 {vide Kr. Berl. Ent. Zeit. 1860, p. 99), but his descrip- 

 tion does not bear this out; moreover, Thomson in his 

 9th vol., when going over the synonymy of the genus, 

 does not quote Kraatz's hygrotopora as a synonym of his 

 hygrohia. On the other hand the description by Thom- 

 son (Joe. cit.) of S. opacula seems to agree very well with 

 this species. I think it not improbable that H. hygrohia, 

 Th., will prove to be a var. of H. elongatida.

A moderate-sized, rather narrow and elongate species, 

 varjning somewhat in colour and size. The antennas are 

 rather long, scarcely thickened towards the apex; joints 

 two and three rather long and slender, three not quite 

 so long as two, four to ten diff'ering little from one another, 

 the first of them longer than broad, the last of them about as 

 long as broad ; eleventh joint not quite twice the length of
