removed. lu B. jjallijies the augle itself is less proiuiueut, and the 

 direction of the side in front of it is less oblique. 



I may mention that the two species show distinctions in their 

 sexual characters, but that these are very difficult of stvidy. Other- 

 wise they are but little dissimilar, though the sedeagus is markedly 

 different. 



I first met with B. annse on the banks of the river Nith, near 

 TLomhill, in September, 1867, and in the two or three subsequent 

 years I found there a few other specimens. These were separated in 

 my collection as " B. pallipes, var. ? " On returning to this spot, after 

 an interval of 40 years, at the end of July, 1910, the species was again 

 met with by my daughter, Mr. Bishop, and myself. It lives in the 

 friable sand of the perpendicular banks of the river, in company with 

 B. pallipes. The only other locality I know for the insect is the 

 Nethy river in Moray, where I found a pair in July, 1907. I have 

 also a specimen given me by the late R. Hislop many years ago, and 

 supposed to be B. pallipes. These are all the specimens I know of. 



I have named the species after one of the names of my daughter, 

 M. A. Sharp, who has been very successful in capturing species of 

 this genus.

This species is really very distinct, though it has hitherto appa- 

 rently quite escaped recognition, the few collections in which it exists 

 agree in calling it "fuscipes," though it is nearer to paUipes and to 

 annae. The tarsi are longer and more thread-like than in any of the 

 allies, and measurement with the micrometer shows that the thorax is 

 just about as long as broad. The elytra are longer than the thorax, in 

 proportion of about 5 — 3. In the more slender specimens the greatest 

 width of the body (i. e., the abdomen beyond the middle) is only 

 I mm., in the broadest examples it is just about 1 mm. The ptmc- 

 tuation of the elytra is very similar to that of B. pallipes. 



The nearest ally appears to me to he pallipes, hut filijyes is much 

 narrower, with more slender legs, and the thorax is not transverse. 

 The front coxa3 are infuscate at the base, as in pallipes. 



The discovery of this species is due to Mr. E. Gr. ElHman, who 

 dug out many examples of it from the nearly perpendicular clay chffs 

 at Overstrand, near Cromer, in Norfolk, in June, 1897. Mr. Newbery
