8. Limosi'iifi seufeltarisHa,]. — Described as follows : — 



" Sp. 8. L. scutellaris. Nigra scutello aterrimo ; facie, coxis, genubus 

 que testaceis ; halteribus alhidis ; tarsorum posticorum articulis ditobus 

 incrassatis. 



"Like the last in character: head black, face and fore margin of 

 the front pale testaceous : thorax glossy black : seutel elongate, opaque, 

 deep black : abdomen dull black : shanks and feet dusky : the fore coxae, 

 the base of the shanks, often the entire of the middle shanks and feet 

 testaceous or rust-brown : 2d joint of the hind feet twice as long as the 

 first, and thickened : poisers whitish : wings hyaline, with pale brown 

 nerves, the costal darker; 2d terminating much nearer to the 3d, 

 which does not quite reach the tip of the wing : smaller than No. 6. 



" With No. 6, but not common ; north of Ireland. Near London ; 

 Mr. Walker." 

 Three specimens of this easily recognized species. There are two 

 smaller dorso-central bristles in front of the strong prescutellar, and the long 

 basal joint of middle tarsi has a small anteroventral spine at middle, while in 

 the male there is no bristle beneath the middle tibise, but there are two small 

 spines at the base of the middle femora beneath. 



9. Limosina nivalis Hal.— Originally described (1833) as follows : — 



" B. nivalis. Niger, hypostomafe femtgineo, alts abhreviatis. (Long. 

 •08.) Dull black : face rusty yellow : legs rufescent : thighs and hind 

 shanks dusky : 2d joint of hind feet twice as long as 1st, scarcely 

 thickened : wings shorter than the abdomen. 



" About the roots of trees during the winter ; leaping far." 



I failed to find this species in the box containing the Borboridw of the 



collection, but it is well known to me from specimens taken in Chippenham 



Fen (Cambs.). It much resembles erratica Hal. ; but the abbreviated wings 



with the outer cross-vein missing make the species an easy one to recognize. 



10. Limosina qiiisquilia Hal. Originally described as follows : — 



"Sp. 10. L. quisquilia. Nigra alls infuinatis ; halteribus fusvis; 

 iibiis mar. simplicibus. 



" Resembles L. crassimana both iu size and character, but the feet 

 are slender, and the fore shanks not clavate in the male : from most of 

 the small species which follow, it differs by the longer seutel and more 

 pubescent legs : I consider it as distinct, though not satisfactorily 

 cliaracterized. 



" Has occurred once or twice along with L. crassimana."
