CRAM BUS EALSELLUS. 285 



Ob-ambus CHRYSONUCHELLUS. 



On the 7th of July, 1883, I received a numerous 

 batch of eggs of this species, laid loose. 



The shape of the egg is a broad oval, numerously 

 ribbed, the ribs very slightly glistening, of whitish 

 colour when recently laid, then turning of a faint 

 drab tint, and later to a dirty brownish-ochreous 

 tint, when a small speck of deeper brown appears at 

 one end. Some were in each stage on arrival. 



On the 9th they had become of an olive-greenish 

 tint, very dingy almost blackish at one end. They 

 began to hatch during the night, and on the 10th I 

 put twenty-five on a turf of Festuca ovina and other 

 grasses from a chalk down, furnished by Mr. Fletcher. 



The newly hatched larva is greenish-grey, with 

 black-brown head and plate on the second segment ; 

 the three hinder segments are very pale ; an internal 

 greyish dorsal vessel is just visible along the middle 

 of the body. 



They were all hatched by the evening and put on 

 turf, together about seventy in number. (William 

 Buckler, 10th July, 1883 ; Note Book IY, 202.)

 Plate CLX, fig. 2. 



On the 10th of June, 1879, I received from Dr. 

 Wood a number of these larvse in different stages of 

 growth, living in silken-lined tubes or galleries within 

 wall-moss (Barbula muralis). 



Some of them were no more than a quarter of an 

 inch long, others were three-eighths and four-eighths 

 to five-eighths and rather more, cylindrical, tapering 

 a little to the head and rather more tapering to the 

 anal end. 



In colour they were pale grey, rather darker
