Collin — Notes on Specimens of Borhoridce and some Ejjhydridce. 243 



Unfortunately there are no specimens labelled quisqiiilia in the Collection ; 

 and, the description being unsatisfactory, it is difficult to say with any 

 degree of certainty which of the specimens are those from which Haliday 

 described his species. There are, however, six specimens of coxaia Stenh. in 

 the Collection, to which Haliday's description of quisquilia might be said to 

 apply ; but there appears to be little justification for placing Stenhammer's 

 name as a synonym, the more satisfactory way being to consider Haliday's 

 species unrecognizable. 



11. Limosina Jaagicola Hal. Described as follows : — 



"Sp. 11. L. fungicola. Nigra nitida, f route opaca ; halteribus nigris; 

 alarum Uneola 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 the hind feet one half longer than 1st, and somewliat 

 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 latter extends scarcely halfway 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, Hollywood. North Devon, and near London ; 

 Mr. Walker." 



Haliday must have included two species under this name ; one with a dull 

 black frons, longer and more pubescent arista, ample wings, more distinct 

 keel between antennge, only one pair of small pre-scutellar dorso-central 

 bristles, and more numerous minute bristles ou thorax, abdomen sliining 

 black without any indication of reddish-browu or red, and middle femur 

 in male with a posteroventral row of 4-5 small bristles near base ; the second 

 species having a frons extensively greyish, wings not so ample, and veins 

 rather less distinct, a smaller second pair of dorso-central bristles in front of 

 the pre-scutellar pair, and less numerous minute bristles on thorax, abdomen 

 brownish or obscurely reddish, with shining black genitalia, and no bristles at 

 base of middle femora in male. This latter is undoubtedly vitripennis Zett., 

 and the na,m.Q fuiigico/a may be restricted to the former. 



12. Limosina erratica Hal. Originally described thus : — 



" Sp. 12. L. erratica. Nigro-fusca fac pedibusque ferrugineiH ; 

 halteribus fuficis : alis in/iiinatis.
