Black, mandibles, and abdominal segments 1, 2, and 3 at the 

 base, rufons ; legs variable. Mesoplenrae smooth and shining, 

 rugose above. Abdomen hardly naiTOwed at the base, rather 

 short ; segment 1 not longer than its apical breadth, 2 transverse, 

 both striato-rugose ; 3 striolated at the base, very smooth and 

 shining at the apex, like the 4th and following, which in the <? are 

 covered with adpressed yellowish hairs, the middle and the apical 

 margin being glabrous. Podiscoidal areolet only i as long as the 

 prsediscoidal, by which the species may be distinguished from 

 every other. Second cubital areolet subquadrate. <? J . Length, 

 2^ ; wings, 5 lin. 



Antennae as long as the body, about 50-jointed ; palpi black, 

 seldom testaceous. Mesothorax sparingly punctate, more shining 

 than, in the other species. Mesopleuraj sometimes obsoletely im- 

 pressed with a longitudinal rugose fovea. The hair of the S is 

 often worn away; the 5 exhibits only a thin pubescence. 



Var. a. Legs black, 1st pair of knees and tibiae fuscous. 



Var. j8. Legs rufous, coxae of the 1st, or 1st and 2d pairs, 

 knees of the 2d and 3d, tibiae of the 3d, and all the tarsi, black. 

 This is described by Nees as the typical form. 



Var. y. Antenna" at the base beneath, and legs, rufous ; femora 

 and tibiae of the 3d pair, and all the tarsi, black at the apex. 

 B. nobilis, Cur. 



This and the preceding are the only species I have not 

 seen ; both occur in Holland ; and Eeinhard gives the 

 distribution of reticulator from England to Syracuse. 

 Taken by Haliday in Ireland, near Holy wood, Belfast, <? ; 

 and by Dale at Monk's Wood, near Cambridge.
