S30 BRITTSH SPECIES OF THE 



Sp. 9. L. nivalis. Nigra facie pedibtisque ferruginosis ; 

 halterihus et alis abbreviatis. 



Borborus nivalis, Ent. Mag. I. 178. 

 Ctirt, B. E. 469. No. 29^. 



Dusky black : face dull rust colour : areola finely pubescent : scutel 

 shorter than metathorax : legs pubescent, dull rust colour ; thighs 

 and often the middle of the posterior shanks dusky ; 2d joint of 

 hind feet not dilated : poisers abortive, dusky : w^ings not extending 

 to the end of the abdomen, sometimes very small, brownish : no 

 second cross nerve : about as large as No. 6. 



Not uncommon during the winter about the roots of trees in 

 the north of Ireland : leaps very actively. 



Sp. 10. L. quisquilia. Nigra alis infumatis ; halteribus 

 fuscis ; tibiis mar. simplicibus. 



Resembles L. crassimana both in 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 scutel 

 and more pubescent legs : I consider it as distinct, though not 

 satisfactorily characterized. 



Has occurred once or twice along with L. crassiinana. 



Sp. 11. L. fungicola. Nigra nitida, f route opaca ; halte- 

 ribus nigris ; alarum lineola costali nigra. 



Glossy black : the pubescence very fine : front opaque, deep black, 

 with a glossy triangle : face elevated between the antennae, 

 rather hoary : legs slender, scarcely pubescent : fore knees and 

 middle feet brown : middle shanks with only a pair of bristles on 

 the outside : 2d joint of hind feet one half longer than 1st, 

 and somewhat thickened : poisers black : wings ample, blackish, 

 rarely hyaline : nerves dusky ; the costal pubescent at the base ; 

 black from the 1st to the 2d main nerve ; the lattef extends 

 scarcely half way from the 1st to the 3d : the sub-marginal cell 

 is wider than usual ; the interval of the cross nerves almost 

 twice as long as the principal one : smaller than No. 6. 



Inhabits fungi, Holywood. North Devon, and near London ; 

 Mr. Walker. 



Sp. 12. L. erratica. Nigro-fusca facie pedihusqiie ferru- 

 gineis ; halteribus fuscis : alis infumatis. 



Approaches the last in character : the marginal and sub-marginal
