beyond the side keels black. Scutellum black. Elytra lacteo-hyaline, nerves white, 

 stigma blackish, nerve granules oblong, distant, those of the costa 9 or 10, occupying 

 the whole width of the nerve. Styles brownish-yellow, their inner angle bluntly 

 prominent, and their hind margin rounded. Anal tube black, the lower half of the 

 apical ring brownish-yellow, and produced into two large, blunt, triangular, spread- 

 ing, dusky, recurved teeth, aperture roundish. Legs brownish-yellow, more or less 

 striped with fuscous. 



I have only seen a single example of this species. 



In addition to these, we have the true G. similis of Kirschbaum, 

 of which I append a short description : — 



Cixitjs similis, Kbm. 

 Head black, with brownish-yellow keels. Pronotum brownish-yellow, beyond 

 the side keels black. Scutellum black. Elytra pale brown, sometimes mottled 

 with darker, nerves whitish, their granules roundish, moderately close, costal 

 granules large, distant, roundish, 8 — 10 in number, not occupying the whole width 

 of the nerve, but placed at irregular intervals, rather on its inner edge. LegB 

 brownish-yellow, thighs black, except at the extreme base and apex. Styles brownish- 

 yellow, hatchet-shaped, their hind margin straight. Anal tube black, its apical ring 

 oblique, without teeth, aperture roundish. 



This species occurs near Norwich, in the Hastings district, and 

 Mr. Saunders has taken it at Woking. I formerly mistook it for 

 G. stigmaticus, Germ. 



The following is an attempt to tabulate the essential characters 

 of the British species of this genus : — 



1 (2) Costal granules not, or scarcely, larger than those of the other nerves... 



1. pilosus. 



2 (1) Costal granules distinctly larger than those of the other nerves. 



3 (12) Nerve-granules round or roundish. 



4 (11) Costal granules more than 10. 



5 (6) Elytra with a broad, transverse, fuscous band proceeding from the stigma 



to the inner margin, an ill-defined fuscous spot in the apex of the wings... 



2. cunicularius. 



6 (5) Elytra without a transverse band proceeding from the stigma. 



7 (8) Anal tube with two long recurved teeth at the apex 3. nervosus. 



8 (7) Anal tube without teeth. 



9 (10) Styles (viewed from the side) hatchet-shaped 4. stigmaticus. 



10 (9) Apical lobes of the styles (viewed from the side) wide, triangular, with 



rounded angles 5. Irachycranus. 



11 (4) Costal granules 8— 10 6. similis. 



12 (3) Nerve granules distinctly oblong. 



. 13 (14) 12— 14 costal granules 7- Scotti. 



14 (13) 9 or 10 costal granules 8. remotus.
