and towai-ds the apex ; apical half of wing thinly clothed 

 with short hlack hairs. Auxiliary vein reaching the margin 

 of the wing above the apex of the inner marginal cell ; apex 

 of first longitudinal considerably dilated ; anterior branch of 

 second longitudinal very short ; fifth longitudinal complete, 

 reaching the margin close to the fourth longitudinal. 



I have only one male specimen of this very fine and dis- 

 tinct species. Tt was taken on the Euahine Mountains, in 

 January. 



Macrocera scoparia, sp. nov. Plate IX., fig. 1. 



Length of antennae, 0-220; size of body, 0-121 x 0-032; 

 expanse of wing, 0-165 x 0066. 



Antennae about twice the length of the body ; joints of 

 scapus light -orange, very short and robiist ; flagellar joints 

 long and slender; basal joints light-brown, but apical joints 

 nearly black, all clothed with stout black hairs. Palpi short, 

 black. Vertex black. Thorax golden-yellow; abroad brown 

 stripe commences just behind the coUare and extends down 

 the centre of the thorax nearly to the scutellum ; a lateral 

 dark-brown stripe on each side, but not extending far beyond 

 the point of insertion of the wings. Scutellum dark-brown. 

 Metathorax dark-brown with yellow sides. Pleurae dark- 

 brown. Halteres smoky - white ; club elongated, oval in 

 shape, covered with short black hairs ; first and third and 

 sometimes other segments light- or dark-yellow^ ; other seg- 

 ments black. Forceps of male yellow. Abdomen clothed 

 with rather long black hairs. Legs pale -yellowy becoming 

 darker towards the tarsus, covered all over with short black 

 hairs ; spurs of tibiae short, dark-yellow ; first joint of tar- 

 sus long, others very short. Wings longer than the body, 

 almost hyaline, but shaded at the apex and at the petiole of 

 the second longitudinal ; covered all over with short black 

 hairs. Auxiliary vein ending just before apex of inner mar- 

 ginal cell ; apex of first longitudinal slightly dilated ; second 

 longitudinal without anterior branch ; posterior branch end- 

 ing some distance before the apex ; costal vein ending a little 

 before the apex. 



This species is extremely common apparently throughout 

 the colony. It may very commonly be taken on windows 

 during all the summer months. It is easily distinguished 

 from all other Macrocera with which I am acquainted by the 

 fact that the second longitudinal has no anterior branch.
