9. M.JacuIusMeU^.: a rather large and well distinguished species, 



fairly common from Penzance to Cambridgeshire and 

 Suffolk, or even to Norfolk (Brandon), and Col. Yerbury 

 took it at Porthcawl. 



10. M. fruncorum Meig. : occurs by thousands everywhere and 



consequently I have omitted to notice records, and mine 

 only extend from Cornwall to Suffolk and Cambridgeshire, 

 unless specimens taken by Col. Yerbury at Nairn and Golspie 

 belong to this species. It may be seen sitting in large 

 numbers in its peculiar upright fashion on the walls of 

 almost any house, but is easily overlooked until the eye 

 has become trained to detect it. Great care is necessary to 

 distinguish it from the next two species and from M. tenui- 

 cauda Lw., but I think its habits are different and it is 

 the smallest species of the group. M. truncorum prefers 

 houses and walls, M. dendrohcenus tree trunks in large 

 woods, and M. petrophilus such stones as occur on dry 

 beaches. 



11. M. dendrobcenus Kow. : my records are from Hampshire, Sussex 



and Norfolk, but I have never specially noticed it as a 

 distinct species when capturing it. I think I have seen it 

 from Cornwall and Somerset. 



12. M. petrophilus Kow\ : Hampshire, Suffolk and Norfolk, and 



I think from Cornwall to Sutherland. Usually taken by 

 me in miscellaneous captures without my recognition of its 

 specific distinctness at the time. Mr. C. G. Lamb has 

 taken a lot of beautiful specimens at Padstow in Cornwall, 

 and I expect it is universally common in suitable localities. 



27. SCELLUS Lw. 

 S. notatus Fabr. : a very distinct and peculiar species, which 

 cannot be mistaken for any other species recorded for Britain, though 

 the allied 8. spinimanus Zett. is almost certain to occur with us. 

 *S'. spinimanus is distinguished by the absence of the blackish round 

 spot on the last portion of the discal (fourth) vein ; the third 

 European species S. dolichocerios Gerst. is known from only one male 

 taken in ffilaud. My records of S. notatus were from only Sussex, 

 Kent, and Essex, until 19U4, when I saw it from Cornwall and Inver- 

 ness, but I do not think it is rare, and it is certainly sometimes 

 abundant amongst marshy herbage near the sea-coast.
