Wings with one marginal and four sub-marginal cellules; the first 

 sub-marginal is very small, and its dividing nervure is, in all the 

 species, often absent, and when present is usually A^'ery faint ; the 

 second rather broad and long, forming a large angle at the 

 bottom, and receiving one recurrent nervure near the centre, at 

 the apex of the angle ; the third a little longer than the half of 

 the second, longer than broad, angled beneath, and receiving one 

 recurrent nervure in the middle ; the fourth is the largest, very 

 broad at the apex, and bounded by the margin of the wing. The 

 lanceolate cellule is contracted ; the costal is divided by a nervure 

 near its apex. In some species the nervures run parallel or nearly 

 so. In the second sub-marginal cellule, in most of the species, 

 there is a well-marked horny point. Antennae nine-jointed : in 

 the female filiform, attenuate at the apex, nearly bare or with 

 only a short pile ; the first joint small, the second of the same size 

 as the first; the third and fourth are the longest and -^qual, the 

 third being often curved underneath ; the remaining joints become 

 gradually shorter and thinner. The apices of the joints are well 

 developed. In the male, with one section, there are longish pro- 

 jections from the base of the third, fourth, and fifth joints; in 

 another there is a small projection from the base of the third ; 

 and with the third section the joints are plain. With all they 

 are more or less pilose. 



* In the recently issued fourth part of Brischke and Zaddach's " Beobach- 

 tungen ueber die Arten der Blatt-u. Holzwespen," the authors have adopted 

 Hartig's sections Leptocercus and Leptopus as distinct genera. I have already 

 pointed out (Ent. M. Mag. x., 84), that Leptocercus (1837) = Ilemichroa (1835), 

 and the latter name having the priority, must, of course, be used ; while, as 

 regards Leptopus, that name cannot be used either, as it is long pre-occupied 

 in Hemiptera, if not in other orders. There being no other name available, 

 that of CamponiscuSy given to it by Mr Newman (Ent. 18G9, p. 215), must, 

 I suppose, be adopted.
