SUB-TRIBE SELANDRIADES. 183 



lateral lobes and scutellum very sparsely and indistinctly punctured ; 

 parapsides dilated; cenchri dull white; basal segment of abdomen 

 impunctate; cerci red. Wings hyaline; stigma pale on lower side. 

 Antennae longer than abdomen, filiform. The lour anterior spurs 

 pale. 



The c? has the antenna as long as the body; the puncturation on 

 head and thorax closer ; the head narrower behind. 



Length 4 4 lines. 



Closely allied to ceneus, but it is larger, more elon- 

 gated, has longer antennae in both sexes, the post 

 costal cellule is, if anything, wider and the cerci red. 

 As a whole it has more of a bluish tinge than ceneus ; 

 in one or two of my Scotch specimens the apical 

 segments of abdomen are very distinctly steel blue, 

 these specimens, too, having the colour of the mouth, 

 joints of the legs and stigma darker than usual. 

 Thomson describes the transverse radial nervure as 

 interstitial, but this is the case only with one speci- 

 men that I have seen. 



Common in Scotland, extending to the extreme 

 north and to the Hebrides, and occurring at an eleva- 

 tion of 3000 feet and upwards on mountains. It is 

 found also in the North of England. 



Sub-tribe SELANDRIADES. 



Antennae short, filiform, rarely thickened at apex; the third joint 

 rarely equal to and generally longer than fourth; 7- to 15-jointed. 

 Wings with two radial and three or four cubital cellules ; basal nervure 

 received near or joined to the cubital. Lanceolate cellule petiolate, 

 contracted, open, or with an oblique cross nervure. Hind wings with 

 the transverse cubital and recurrent nervures present, or the trans- 

 verse cubital may be absent and the recurrent present, or both may be 

 absent. Legs generally short; calcaria never reaching to middle of 

 metatarsus ; tibiae usually longer than tarsi ; patellae distinct or, more 

 rarely, scarcely developed. CJypeus incised or truncated at apex. 

 Mandibles short and thick at the base, and with a short tooth at the 

 apex. Body short and plump, rarely elongated. The second and third 

 cubital cellules receive each a recurrent nervure. When there are only 

 three cubital cellules the first is much larger than the second. 



The larvae have twenty- two legs. In form they are varied, some 

 being longish and cylindrical like those of the Tenthredinides, while 

 others are short and stumpy. Green is the predominating colour, and 

 they are not (so far as is known) ornamented with lines or spots of 

 different colours. A few (Blennocampa, Hoplocampa) bear long branched
