166 AMBLYNOTUS LONGITARSIS. 



2. AMBLYNOTUS FEMOEALIS. 

 PL VIII, fig. 2. 



Melanips femoralis, Cameron, Trans. Ent. Soc., 1883, p. 371. 



Black ; the greater part of anterior femora, the apical fourth of 

 middle, and the tibiae and tarsi, fulvous-testaceous ; the apex of hind 

 tibiae and tarsi more or less fuscous. Antennas nearly as long as the 

 body, becoming very slightly thickened towards the apex; the third 

 joint nearly one fourth longer than the succeeding, the others becoming 

 gradually shorter to the penultimate, which is not half the length of 

 the last. Parapsidal sutures narrow, becoming obsolete towards the 

 base of the mesonotum; the puncturing on scutellum is not much 

 stronger than on mesonotum, except on the sides, which are rugose ; 

 inesopleuraa for the greater part smooth and shining, only the extreme 

 lower part being punctured and opaque ; coxae opaque, finely punctured, 

 except behind, where they are smooth and shining. Abdomen not 

 much longer than the thorax, smooth, shining ; the hair fringe sparse. 

 Legs and wings as in opacus. 



Length 4 m.m. 



From A. opacus the present species may be known 

 by its darker coloured femora and lighter coloured 

 tibiaD and tarsi, by the smaller size of the scutellar 

 fovese, less strongly punctured scutellum, less clearly 

 impressed parapsidal furrows (which are, however, 

 perfectly distinct), and less hairy thorax. A. longi- 

 tarsis is easily distinguished from it by the equal third 

 and fourth joints of antennse. 



Rare. Bonar Bridge, Sutherlandshire. 



B. Parapsidal furrows obsolete; the third and fourth 

 joints of antennse in ? equal in length. 



3. AMBLYNOTUS LONGITARSIS. 



Amblynotvs longitarsis, Reinh., B. E. Z., iv, 224, 2 ; Thorns., 

 Oef., xviii, 416, 2. 



Black ; the femora, tibiae, and tarsi reddish-yellow, the base of femora 

 and hind tarsi fuscous or blackish ; wings hyaline, suffused at the base 

 with fulvous ; flagellum inclining to fuscous on the lower side. Antennas 

 a little shorter than the body, not much thickened towards the apex, 

 the third and fourth joints equal, the last nearly twice the length of the 

 penultimate. Sutures of mesonotum very indistinct, almost obsolete
