ments ; the underside uniform pale yellowish, as are the legs ; 

 tibiae and tarsi rather more tawny ; breast and coxae rather 

 bristly ; poisers yellow. The wings ample, clear, fringed, the tip 

 conic, the nervures at the base yellow, the remainder brown or 

 subtestaceous ; the cross nervures darker where the bands 

 cross ; the bands black or inky ; a diagonal band widest on the 

 underside rises near the outgoing of the second longitudinal 

 nervure, and crosses the second transverse one ; this is followed 

 by a short one, which is narrowest at its tip, proceeding from 

 the upper margin, and going no farther than the third cell ; a 

 third band sloped in an opposite direction to the first, widest 

 and darkest at its origin, which is behind the coming out of the 

 mediastine nervure, and narrowing towards the tip, crosses the 

 first transverse nervure, and runs somewhat towards the tip of 

 the first; and there is also a small spot near the base towards the 

 hinder margin where the fifth nervure is emitted, and a minute pale 

 one after the transverse nervure of the costal cell. Length i*4 

 line; expansion of the wings 5 lines. The female is larger, and 

 has the abdomen more ovate; the sheath of the ovipositor is short, 

 with its edges and tip brown ; length 3 lines ; breadth 5^. lines. 



It may be remarked that in both this and T. artemisice, 

 which deposit their eggs in substances easily reached, the 

 ovipositor is of moderate length. 



Note on Bibio clavipes Mg. and B. lepidus TiO&vr.—Bibio lepidu* 

 Loew. is the species that for a long time was considered by British entomolo- 

 gists to be clavipes Mg. In fact, lepidus was only distinguished from clavipes 

 and described a year or two ago. The true clavipes appears to be very rare in 

 England, the only specimens extant being some collected by the late Mr. Dale, the 

 localities of which are doubtful. In Scotland, however, it seems more common, 

 as I have examples from several localities. I therefore take this opportunity of 

 recording it as a British species beyond doubt. B. lepidus (only recorded 

 hitherto from England and Ireland) is also a Scottish species. Regarding these 

 species I will say more in a paper on the Scottish species of Bibio, which I have 

 in contemplation, and in aid of which I will be glad of information from anyone 

 who has studied Scottish Diptera. — F. Buchanan White. 



CAPTURES OF SPIDERS IN SCOTLAND DURING 1872

URING the past year I have collected Spiders in various Scottish localities, 

 most of which have been kindly verified by the Rev. O. P. Cambridge,
