Abdominal segments, nearly hairless, greenish-black with 

 the exception of the tenth or terminal segment, which 

 is distinctly black and polished. 



The first and second are encircled by eighteen small 

 rounded chitinous studs ; the third, fourth, fifth, and 

 sixth segments have each twelve ; the seventh and 

 eighth have sixteen ; and the ninth has fourteen 

 similar studs. 

 Habits. 



The larva appears to be strictly nocturnal in its haliits, 

 and is usually found in low-lying country. 



During the day time it hides in a little tunnel-like nest, 

 made amongst the roots of a grass tussock. In con- 

 nection with the nest the insect bores a vertical shaft, 

 some six or eight inches deep, down which it retreats 

 when alarmed. 



Prior to its pupation, which takes place in July or August, 

 the larva makes a vertical addition to its shaft, 

 extending it upwards for an inch or two above the 

 surface of the ground. 



Specimens of these extensions are on the table, and may 

 be seen to consist of a silk tube, 8 mm. in diameter, 

 strengthened by an outer covering of grass, varying 

 considerably, both in quantity of material, and mode 

 of construction. 

 Pupa. 



Red-brown, thorax and wing-cases darker, 25 x 6 mm., 

 cylindrical, terminating abruptly. 



When touched it shows great irritation and wriggles 

 violently. 



Ventral side of abdomen furnished with about thirty 

 bristles, 3 mm. long, arranged nearly at right angles 

 to the body, in three longitudinal lines, one median 

 and two lateral. 



The eighth segment projects slightly on the ventral side, 

 bearing a hardened plate, set downwards at an angle 

 of 45° witli the body. 



This organ, with the bristles on the ventral, and the 

 adminicular on the dorsal surfaces, are probably of
