finely reticulated, the raised upper part smooth. Metanotum smooth, the 

 outer edge finely aciculated— The colour on the top of thorax is tolerably 

 uniform ; on the pleurae the blue is largely mixed with violaceous. 



The scattered white hairs on the mesonotum are very conspicuous ; 

 the apical abdominal segments are fringed with white hair. 



Aphelin^e . 



Triolynx, gen, nov. 



Antennae placed nearly opposite the lower part of the eyes ; 8-jointed, 

 the scape not reaching to the middle of the eyes, compressed below, roundly 

 narrowed at the base and apex, the pedicle bare, shining, narrowed at the base, 

 twice longer than wide, as long as the following joint which, with the next, is 

 a little longer than wide, the following as wide as long ; the apical three form 

 a well-marked, clearly separated club, wider than and as long as the preceding 

 three joints united, rounded at the base and gradually narrowed towards the 

 apex. Eyes large, oval, pilose ; the malar space as long as the antennal 

 pedicle. Ocelli in an equilateral triangle. Olvpeus narrowed in the middle 

 the sides roundly dilated. Occiput transverse ; the temples very short. 

 Parapsidal furrows complete, curved. Scutellum nearly as long as the meso- 

 notum, transverse at the base, roundly narrowed towards the apex, twice 

 longer than it is wide at the base ; there is a distinct furrow down its middle. 

 On the lower part of the mesopleurae is a clearly denned longitudinal furrow, 

 which is placed higher up at the base than at the apex. Marginal nervure 

 twice the length of the basal ; the stigmal branch much shorter than the post- 

 marginal ; 2nd abdominal segment as long as all the following united, the 

 apical two gradually narrowed to a blunt point. 



The pronotum is half the length of the mesonotum ; it becomes gradually 

 widened towards the apex. The head is wider than the thorax ; the abdomen 

 is slightly longer than the thorax ; the metapleurae at the apex project into a 

 triangular point. Tibia? unarmed. 



Belongs to the Aphelinince, tribe Aphelinini. It cannot well be con- 

 founded with any of the described genera ; the clearly defined, three-jointed 

 antennal dub, the hairy eves, very long marginal nervure and the furrowed 

 scutellum are four points which should enable it to be easily recognised. In 

 Ashmead's Arrangement (Mem. Cairn Mus. i ; 345) it runs close to Atieristus 

 How. 



Triolynx clavicomis, sp. n. 



Blue, the head darker coloured than the thorax, the 2nd and following 

 segments of the abdomen black, the antennal scape pallid yellow, the flagellum 

 densely covered with longish white pubescence, the legs pallid yellow, covered 

 with a white pile, the coxae blue. Wings hyaline, the nervines pall id ; the 

 edges ciliated, the ciliae longer on the base of the costa. Female. Length, 

 2 mm.
