far north as Fontainebleaii. De Selys-Longchaitips does not inclnde 

 it m his Catalogue of Belgian Orthopfera. Haworth's specimen may 

 not have been British at all, or perhaps was wrongly labelled or placed 

 in his collection, and, as has been said before, when Stephens saw it, 

 it had been captured already " many j^ears." 



It should be looked for about August and September amongst 

 the flower heads of thistles, &c., and is easily known by its slender 

 iniild and pale colour. 



ii.— NEMOBIUS, Serville. 

 In this genus the spines of the posterior tibire are long, slender, 

 and moveable, not stout and fixed as in Gryllus. The first joint of 

 the posterior tarsi is smooth above. The species in Britain {N. syl- 

 rrstris) is easily distinguished by its small size and truncated elytra 

 from the rest of our Gn/UidcB. There are two other species found in 

 Europe, but they have a shorter ovipositor and longer elytra, and 

 neither of them is likely to be found here.

Small size. Generally chestnut-brown colour, with paler markings ; beset witli 

 fine hairs. Head short, black, with the sutures yellow between the eyes, forming a 

 pentagonal marking, from tlie superior angle of which the pale streak is prolonged 

 a short distance backwards. Eyes paler. Maxillary palpi with the terminal joint 

 dilated, ending in a funnel-shaped excavation, of wliich the anterior lip is longer than 

 tlie posterior. Pronotum with disc testaceous, and lateral lobes black. Elytra abbre- 

 viated, trun(^ated, considerably longer than the pronotum in (J , with no oblique vein.'; 

 in the harpa, and no transverse veins in the speculum ; about the length of the 

 pronotum in ? , rounded on the inner margin (anal angle). Veins fuscous. Wings 

 absent. Anterior tibise with an external auditory foramen only on the outer side. 

 Posterior femora with pale markings. Posterior tibiae with the spines long and 

 moveable, six terminal, and three above in either margin, placed alternately. First 

 joint of the posterior tarsi hairy, not sulcate above or serrate. Abdomen above witli 

 pale blotches, sometimes only showing as a row of dots down the centre. Cerei 

 pale. Subgenital lamina in $ compressed, bluntly pointed. Ovipositor straight, 

 reaching beyond the tibio-tarsal articulation. Length, 9—11 mm. 



Amongst dead leaves in woods, July to October. This species 

 was very common near Lyndhurst in September, 1887, and probably 

 occurs in many woods in the south of England. It is found all over 

 Central Europe, and in Spain and Algeria, and I have taken it plenti- 

 fully in the wood at Meudon, near Paris.
