of the dilated part in puhescens and Lesnei there is a small blunt 

 tooth, which is wanting in decipiens ; the branches of the forceps meet 

 at the apex in puhescens and decipiens, but do not do so in Lesnei, 

 which is also of a darker and more uniform colour than the two other 

 species ; the wings are abbreviated ; the antennae have 12 joints.

EAKE HTMENOPTERA AND BIPTERA IN CORNWALL. 

 BY THE REV. T. A. MARSHALL, M.A., F.E.S. 



On page 140 of this vol. Mr. Saunders mentions localities for 

 some of the scarcer Aculeata. May I be permitted to add that Methoca 

 occurs not uncommonly in this district ? The precise spot is on the 

 sandy banks of the river Lyuher, north of Nottar Bridge, where I 

 have seen six or seven at various times, and made some captures. The 

 ground was formerly poisoned by the vernal overflow of the stream, 

 impregnated with metallic matter from the mines in the hills, but is 

 now nearly recovered, owing to the stoppage of mining. Myrmosa 

 melanocephala is quite common at the same spot, and may be taken ad 

 libitum late in the summer. But I have met with no ^ of either 

 species. 



The following are either new to the British fauna, or for other 

 reasons interesting ; they are the more remarkable from the general 

 entomological poverty of the district ; it is worth while to seize the 

 opportunity of placing them on record. 



I have been gratified by the re-discovery here of Haliday's long 

 lost genus Neoneurus (Ent. Mag., vol. v, p. 213) ; I have taken 

 both sexes by sweeping flowers in the fields. The wings only of the 

 insect were known, as drawn by Haliday, and copied by Van Vollen- 

 hoven. They differ widely from those of any other Braconid. I have 

 named the species N. Halidaii, and placed it provisionally as an 

 aberrant form of the Areolarii, next after Orgilus, with description 

 and figure, in Andre's " Species."
