Apatolestes lutulentus, sp. nov. 



Female. — Upper surface blackish-brown, with short 

 scattered white hairs on the thorax and abdomen ; a thicker 

 layer of these hairs on the posterior margins of the abdo- 

 minal segments. On the lower surface these white hairs 

 are more abundant, especially under the head. First and 

 second joints of the antennae tawny ; palpi yellow ; eyes with 

 short hairs. Tibiae paler brown than the rest of the legs. 

 Wings slightly tinged with brown, the stigma indistinct. 

 Length, 15 mm. ; wing, 11^ mm. ; breadth of the abdomen, 

 6 mm. 



Bab. Christchurch(?) (Clark). 



The sides of the abdomen are straight, and its length is 

 about one and two-thirds its breadth. The hind tibiae have 

 well-developed spurs. It is possible that this insect may 

 have come from Taranaki, as I have never seen it at Christ- 

 church.

"Three basal cells much prolonged. Third longitudinal
