eyes, cylindrical basal joint stout, from behind the eyes head 

 broadly rounded to apex. Prothorax not as broad as head, 

 swelling out in line with base of forewings and of uniform thick- 

 ness to hind pair. Wings of the usual elongate form, parallel on 

 the costal margin, narrowly rounded at the tips. All the segments 

 of the legs swollen, hairy on the tibiae and tarsi. Abdomen 

 elongate [damaged]. 



Hah. — Sydney, N.S.W.; taken round the lamp in the house, 

 6 : X. : '02 (W. B. Gurney). 



Oligotoma agilis, n.sp. (Plate xx., figs. 4-6.) 



Length 1 2 mm. 



General colour ferruginous mottled with dull yellow; mouth- 

 parts and tarsi of fore legs lighter; the whole insect clothed with 

 short scattered black hairs. 



Head very large, half as long as thorax, convex, rounded; 

 antennae standing out in front of eyes, 9-jointed [apparently muti- 

 lated], 1st broadest, cylindrical; 3rd longer than 2nd, the next 

 moniliform, gradually increasing in size to the tip : eyes small, 

 not projecting, coarsely faceted, irregularly reniform. Thorax 

 not quite as long as abdomen, divided into three distinct seg- 

 ments, the central or mesonotum longest; wings wanting; fore 

 legs with femora at tibia thickened, the 1st tarsal joint dilated 

 into a broad round disc, flattened beneath and impressed with a 

 median parallel suture; 2nd tarsal joint small, coming to a point 

 at apex, and furnished with small sharp claws; middle legs not 

 so robust; hind pair with the femora thickened, and the tarsi 

 formed of two large joints terminating in large tarsal claws. 

 Abdomen of uniform circumference, apparently composed of ten 

 segments when viewed from above, but the 9th (much smaller 

 than the rest) appears to form a part of the 10th when viewed 

 from the side, rounded at the extremity. Anal tubercles large, 

 finger-shaped, two-jointed, standing out on the sides. 



Bomen, Wagga, N.S.W; two specimens taken under stones in 

 April.
