220 HOAIIEOSUMA NEBULELLA. 



dingy greenish-yellow, variegated with purple marks, 

 the legs barred with black. 



I bred no imagos the following year, but specimens 

 of a pretty Chalcid, Monodontomerus sevens, two species 

 of Diptera, Trypeta serrahdx and T. solititialis, 

 and about a dozen specimens of a small Hemipteron 

 emerged from the thistle-heads. (George T. Porritt, 

 12th May, 1884; Entom., June, 1884, XVII, 143.) 



HOMCEOSOMA N1MBELLA. 



Plate CLVII, fig. 3. 



On the 14th of September, 1869, I received from 

 the Rev. John Hellins six larvae of this species, feeding 

 on seeds of ragwort. They were short and thick, 

 about three-eighths of an inch in length, tapering 

 towards the head and very little on the three hinder 

 segments ; each segment was subdivided by oue 

 transverse wrinkle towards the end. 



Ground colour pale canary-yellow, or in some 

 examples pale dirty greenish- white ; a broad dorsal 

 stripe of dark dull purplish red or brown, and a broad 

 band along the side of the same colour, through which 

 runs an interrupted line of pale ground colour ; 

 then in a stripe of the ground colour are the black 

 spiracles ; a little below them is a blotch of purplish 

 brown under each, and lower down is a line of the 

 same colour ; the belly and legs are of the pale ground 

 colour ; the head is olive-green or brown, and a 

 shining plate is on the second segment of pale olive- 

 brown or green, and broadly bordered behind with 

 black ; this semilunar black border is, however, 

 dorsally divided by a thread of the olive ; the front 

 edge of this segment is pale whitish-yellow. 



These larvae spun little webs and hibernated in them 

 until spring, when after some time they pupated, and 

 the moths appeared from the 4th to the 14th of
