Black ; antennae filiform, longer than tlie abdomen ; the first joint 

 globular, much longer than the second, the third and fourth nearly 

 equal, the remaining joints nearly equal. Head a little narrower than 

 the thorax, smooth, shining, covered with a fine grey pile ; frontal 

 sutures distinct. Tegula) and basal edge of pronotum white ; scutellum 

 flat, very smooth and shining ; cenchii small, dull white. Abdomen a 

 very little longer than the head and thorax, saw projecting, hairy at the 

 apex ; sides of abdomen covered with a white pile. Legs : base of coxa?, 

 femora for the greater part, extreme apex of posterior tibia) and apical 

 joints of tarsi black ; apex of coxa), trochanters, knees, tibia) and base of 

 tarsi, white. Wings clear hyaline ; costa at base, and base of stigma pale 

 testaceous ; apex of stigma and nervures, black. The tr. radial nervure 

 is interstitial or received in the fourth cubital cellule ; the second recur- 

 rent nervure is received a very little in the front of cellule ; the second 

 cubital cellule is longer and thinner than third, and is angled where it 

 receives the recurrent nervure ; the third cellule is wider at apex than 

 at base; the second tr. cubital nervure is bent slightly downwards in 

 the direction of the base of the wing ; the third is curved in the middle, 

 and runs in the direction of the apex of the wing. 



The J has the antenna) a little longer than the body, covered with a 

 short stiff pile, the joints thicker and more flattened than in the $ , their 

 general appearance being as in Priophorus (Cladius); genital parts 

 pale testaceous. 



Length 24 2ft lines. 



This species may possibly be identical with B. uncta, 

 King, but Hartig (Blattw., 269) describes the antennas 

 in the $ (the only sex he describes) as " etwas kiirzer 

 als der Hinterleib ;" and Thomson (Hym. Sc., i, 219) 

 as " longis, abdomine fere longioribus " in both sexes ; 

 whereas our species has them longer than the abdomen 

 in both sexes (in the $ as long as the entire body). 

 The only other species with which it can be confounded 

 with (belonging to the same section of the genus) is 

 B. sulserrata, which, however, has the third antennal 

 joint distinctly longer than the fourth, the legs black 

 at the base, the pronotum but very slightly marked 

 with white, cubital cellules broader, &c. 



I bred this species from a green spiny larva which 

 fed on Alchemilla vulgaris, as described by Degeer
