106 NEMATUS CANALICULATUS. 



I have taken a specimen of imperfectus near Glasgow, 

 and other two on Craig Dhu, Kingussie, at an eleva- 

 tion of about 2000 feet, among ferns. 



Zaddach had specimens from Finland, Germany, 

 and Silesia, but only seven individuals in all.

Antennae as long as the abdomen, tapering considerably towards the 

 tips, black, bare, the third joint shorter than the fourth. Head reddish 

 testaceous, the vertex around the ocelli, and the part surrounding each 

 antenna, black ; the face whitish, apex of mandibles piceous, palpi 

 pale testaceous ; the vertex is finely punctured and covered with close 

 white pile. Thorax reddish-testaceous, the pronotum and sides paler; 

 mesonotum semi-opaque, very finely punctured, and with three distinctly 

 separated black marks ; the pleurae distinctly granulated, semi-opaque ; 

 the sternum black and finely punctured ; there is also a small black 

 line on the sides below the wings ; the metanotum is entirely black. 

 Legs pale yellow, a short thin line over posterior femora, the apex of 

 posterior tibise, and the tarsi, black ; the claws are distinctly bifid. Wings 

 hyaline, costaand stigma sordid luteous ; the second recurrent nervure 

 is received at some distance in front of the second transverse cubital; 

 the second cubital cellule is a little more than one quarter longer than 

 third. Abdomen cylindrical, longer than the head and thorax, finely 

 punctured at the base, the dorsal surface black to the seventh segment, 

 the sides and belly whitish-yellow, marked with black spots. The saw 

 projects beyond the length of the cerci, black, bare, shining ; the cerci 

 longish, fuscous, pointing outwardly. 



The (^, according to Zaddach, is rare compared to the same sex of 

 caprece ; it is very lightly coloured, the red ground colour on the vertex 

 and mesonotum being visible; it has also the black spots on the meso- 

 notum borne by the $ , but they are larger, although not united, and 

 there is also a black spot on the scutellum. The abdomen is black to 

 the anal parts, the belly being, however, paler than the rest. 



Length nearly 4|- lines. 



This species differs from N. caprece in the granulated 

 punctured pleurae, less shining body, of which the
