DESCRirXIONS OF FIVE NEW, OR LITTLE KXOWN, SPECIES OF 

 BRITISH TENTUREBINIDJE. 



BY P. CAMERON, JUN^. 



Nemati's flavipejjwis, sp. n. 

 N. niger, nifidiis, hreviusculus, crassiusculus ; facie inferne, orhitis 

 oculoriim late, teguTis, pronoti anguUs, ano, ventre pro parte, pedibusque 

 rufo-jiavis ; alls Jlavescentihus . Long. 1\ — 1\ I'm. 



? . Antennae longer than the tliorax and abdomen, black, bare, almost shining ; 

 3rd and 4th joints nearly equal ; tlie remaining joints a little shorter, and tapering 

 towards the apex. Head with frontal sutures vci-y distinct, punctured in front, the 

 part between the antennae strongly projecting ; black, the face (including the portion 

 between the antennae) and the eyes (especially behind) broadly surrounded with 

 reddish-yellow ; mandibles deep brown. Thorax black, shining ; the pronotum edged 

 with obscure yellow; cenchri large, white. Abdomen broad, dilated towards the 

 middle, the apex bluntly pointed ; the colour black, smooth and shining ; the anus 

 and ventral surface in the centre reddish-yellow. Cerci moderately long, pale yellow, 

 their apices pointing inwardly ; saw slightly projecting. Feet reddish-yellow ; coxae 

 partly, and femora at base, more or less marked with black ; the three last joints of 

 posterior tarsi fuscous. Wings ample, strongly iridescent, yellowish ; ncrrvires, costa 

 and stigma reddish-yellow ; 2nd sub-marginal cellule nearly double the length of 

 the 3rd, which is scarcely dilated at the apex ; 2nd recurrent nervure received a little 

 in front of the 2nd sub-marginal. 



This species agrees very closely with the dcscriptiou of N. hracliij- 

 notus, Foerster, Yerh. pr. lihcinl., 1854, p. 295, pi. 5, fig. 13, but must 

 be different, as that species is considerably larger, has brownish tarsi, 

 shorter antennae, " ein wenig kurzer, uamentlich als der Iliuterleib," 

 and in the rather long descrii^tion no mention is made of the wings 

 being yellowish. Of the British species it has the greatest reseinblniico 

 to N. Zetterstcdti, \)h\n., = miniatus,l[lig.,h\\i it is also larger, and has 

 the belly com])letcly red, ■« ith the posterior tarsi black. 



One specimen, taken in June at lianuocli, and two at Kingussie; 

 in ])(»1h places by sweeping in marshy ground. 



Nematus haccaeiim, sp. n. 



Niger, snhnitidns, ore, pronoti liviho, teguJis, conta, stigvmte, pedi- 

 busque albidis ; ano testaceo ; alis hyalinis. Long, fere 1}^ I in. 



? . Antennae shorter than the body, comparatively thick, tapering towards the 

 apex ; (lie colour black, obscure brown at apex ; the 3rd and 4th joints about equal ; 

 the last joint tliinner, and apparently a little longer than the 8th. Head black, 

 shining, the vertex finely punctured ; the labrum and clypeus partly white ; man- 

 dibles blaeki.sh ; on the lower side tlierc is a broad pale ring surrounding the eyes. 

 Tliorax black, sliining ; mesonotum finely punctured ; pronotum thinly edged with
