 Taken in great abundance in the salt marshes at Dumfries, 

 also near Edinburgh, at Bi'ighton, and Weymouth by 

 Dr. Sharp ; and, probably, as he suspects, generally repre- 

 senting S. tricornis, Hbst., in British Collections, which 

 has apparently hitherto only occurred at Deal. 



Compared with tricor7iis, which it closely resembles in 

 form and colour, it is considerably larger on the average, 

 with the thorax and elytra not so closely punctured, the 

 thoiax not quite so bulky in proportion, with its sides and 

 posterior contraction rather straighter, and the faint smooth 

 irregular spaces on each side of the mesial line more pro- 

 nounced, and the black suffusion on the elytra more confined 

 to the base. In the male, the head has a pyramidical ele- 

 vation on each side, instead of a short but distinct horn ; 

 and, in a fully develoj)ed male in ray collection (there are 

 mostly two forms of the male in this genus), the thoracic 

 spine is considerably more developed than in any tricornis 

 I have seen. In spite of this extra development, and the 

 larger size of the insect, it will be observed that the tubercles 

 on the head are not so highly developed as in the smaller 

 species. 



M. Fauvel appears to have formed an erroneous idea with 

 regard to this insect, considering it a Southern variety of 

 B. tricornis, and apparently not being very clear as to his
