88 NEMATUS CLIBEICHENSIS. 



28. NEMATUS CLIBRICHEKSTS. 



Nematus clilrichensis, Cam., Fauna, 32, 13 (1S78) ; Andre, 



Species, i, 138; Cat., 19,* 110. 



<$. Antennae black, as long as the body, almost bare of pubescence, 

 slightly flattened, each joint drawn out to a truncated, bead-like 

 point at the apex, which is thicker than the base of the succeeding 

 joint ; the fourth joint is distinctly longer than the third, the rest 

 become gradually shorter and thinner. Head black, sparsely covered 

 with longish black hair ; the vertex finely punctured, frontal area dis- 

 tinct ; palpi black. Thorax smooth, shining, sparsely covered with 

 long black hair ; pleurae scarcely so shining as the mesonotum, punc- 

 tured, and covered with long black hair ; the cenchri are very pale 

 white. Abdomen slightly punctured at the base, the last segment and 

 the gaping anal lobes sordid testaceous. Legs black, the coxae and 

 base of tibiae sordid testaceous, the posterior tibiae totally black ; the 

 four anterior tarsi are longer than the tibiae, the posterior are also 

 longer, but not so long in proportion as the anterior ; the spurs are very 

 short. Wings hyaline, nervures black, the costa and stigma sordid 

 white ; the first cubital cell is small, its nervure very pale ; the second 

 cellule is almost double the length of the third, and forms a very 

 sharp angle where it receives the first recurrent nervure ; the third is 

 a very little widened at the base. The tegulse are black. 



Length a little more than 3 lines. 



At the first examination I took this to be the un- 

 described male of N. Thomsoni, but a closer comparison 

 showed so many points of distinction as scarcely to 

 warrant such a conclusion ; e.g. the pubescence is 

 shorter, blacker, and thinner ; the tegulse are quite 

 black ; the legs much darker coloured ; the costa 

 and stigma are not so clearly white ; the vertex has 

 the puncturing more rugged, and the labrum is quite 

 black. 



I captured one specimen on the top of Ben Clibrich, 

 Sutherlandshire (3180 feet high) in June. 



Obs This may possibly be the $ of hyperboreus, Thorns., the $ of 

 which is stated to have the labrum, stigma, costa, and anus dirty white, 

 the anterior tibiae and tarsi white, and the posterior and apex of tibia! 

 black. If it really be the $ it would thus differ from the $ in having 

 the labrum and tegulae black, the stigma yellowish-white, and the legs 

 very much darker.
