318 CRAMJBUS WABRINGTONELLUS. 



near full growth they inhabit tubular galleries two 

 inches long and of irregular figure, and firmly attached 

 to the grass in an upright position with the lower end 

 touching the ground, and fabricated of grey silk 

 covered with particles of moss, frass, and grains of 

 earth. 



When full-grown the larva is three-quarters of an 

 inch long, of moderate stoutness, cylindrical, though 

 tapering a little at the three hinder segments, and the 

 head is rather smaller than the second ; the segments 

 are well defined and have a subdividing* wrinkle about 

 in the middle of each ; the ground colour of the body 

 is a dirty greyish-green rather inclining to glaucous, 

 and a little paler on the belly ; the skin though dull 

 is yet clear enough to show a darker dorsal pulsating 

 line ; the shining head, and plate with a wide behind 

 dorsal division are of lightish warm brown, both 

 dotted and marked with darker brown ; the mouth is 

 blackish ; the shining spots on the back and sides, 

 each bearing a hair, are of a darkish warm brown on 

 the back, lighter brown on the sides ; the small round 

 spiracles are black, the anterior legs ringed and tipped 

 with darkish brown, the ventral legs fringed with 

 dark brown hooks ; when full-fed and about to spin 

 up, the colour of the skin changes to a pale pinkish- 

 farown. 



The pupa is enclosed in an oval cocoon half an inch 

 long and a quarter of an inch wide, made with similar 

 materials to those of the gallery, but is more tough 

 and stronger, and sunk partly in the earth. 



The pupa itself is three-eighths of an inch long, 

 with no peculiarity of shape, with longish wing-covers, 

 leg- and antenna-cases, the tapering abdomen ending 

 in a short truncated projection, the spiracles rather 

 prominent; the colour at first is pale yellowish-brown 

 and shining, changing to dark brown a little before 

 the insect is disclosed. (William Buckler, 30th Sep- 

 tember, 1881 ; E.M.M., November, 1881, XVIII, 129 

 —131.)
