THE GENUS GONIODOMA. 115 



limoniella are of much the same shape as those of C. lixella, hut 

 palpable differences in the venation exist, the most important 

 being that the discoidal cell is perfectly open. The subcostal 

 traverses the wing in one bold and unbroken line, its fourth 

 branch terminating on the costa, and the median is seen to be 

 branched. 



The hind wing is much narrower than any Coleophora I 

 have examined, and the discoidal cell open, but the venation 

 here is very faint and extremely difficult to demonstrate satis- 

 factorily on account of the small size and delicacy of the 

 wing membrane. C. lixella is evidently closely allied to 

 Goniodoma, holding a position between the two genera. 

 Briefly to recapitulate, the open discoidal cells and almost 

 setiform hind wing, coupled with the habit of holding the 

 antennae, constitute, to my mind, a sufficient reason for retain- 

 ing Goniodoma, at least, until we see our way to a thorough 

 revision of the whole of the Coleophoridse. 



The larva of auroguttella has been figured and described by 

 Fischer von Roeslerstamm (Plate 86), and is, I believe, the 

 only species of the genus at present recorded. The head is 

 yellowish brown; the 2nd, 3rd, 4th, 11th, 12th segments 

 yellow, and the 5th to 10th inclusive whitish. The i3th 

 segment is black above, the 3rd segment being the broadest. 

 The following rough description of the larva of limoniella may 

 be useful for comparison. Length about 2'", width almost 

 uniform, the 2nd segment being slightly broader than the rest. 

 Colour pale yellow throughout. Head rich chitinous brown, 

 2nd segment with two rounded plates of the same colour, 

 separated by a pale yellow triangular patch, the apex of which 

 points to the head ; 3rd segment with two dorsal brown plates 

 and two smaller subdorsal ones, the latter being anterior to 

 the dorsal. Between the 8th and 9th segments two longitudinal 

 internal chitinous structures are visible through the skin, being 

 probably connected with the dorsal vessel. The last segment 

 is protected by a rich brown chitinous plate. There are also 

 small plates on the 2nd, 3rd and 4th segments in the spiracular 

 region. This larva may be found about the end of August on 

 the flower-heads of Statice limonium in its case formed of a 

 withered calyx. Later on it bores into the stems to pupate, 

 when the hole is closed up and the case generally drops oft'.
