OBSERVATIONS ON TINElNA. 137 



dorsal stripe, \vhich is more slender and white on the three 

 anterior segments ; above the spiracles is a slender whitish 

 line, the space between which and the dorsal stripe is of an 

 oHve grey, lather darker anteriorly and darker on its upper 

 and lower edges ; head dark brown, mottled with black ; 

 second segment brown, with a black semi-lunule on each 

 side of the dorsal line. 



This larva forms tubes of sand amongst the roots of its 

 food -plant, Scleranthus perennis, which, in Babington's 

 " Manual of British Botany," is given as occurring in 

 " sandy fields in Norfolk and Suffolk." 



The larvae collected by Herr Hofmann at the end of May 

 reached me on the first of June. 



Argyrestlda Sphnella. Of the larva of this insect I 

 received som.e specimens from my industrious correspondent 

 at Scarborough, Mr. T. Wilkinson, on the 20th of May. 



These larva were 3 lines in length: greenish-grey, with the 

 dorsal vessel showing a faint rosy tinge ; head dark brown, 

 almost blackish-brown ; the second segment above with two 

 brown spots, front edge of second segment whitish; anal 

 segment brown. 



The habit of these larvae was rather peculiar, being con- 

 fined to the stems of the Jiower-shoots ; it bores down these 

 before the buds are expanded, and by this means some of the 

 central buds assume a withei-ed and brownish appearance, 

 thus betraying the whereabouts of the larva. 



* Coleophora Unipunctella, Zeller. In August last I re- 

 ceived from Dr. Schlager some larvae of this species, feeding 

 on the seeds of Chenopodium Myhriclum. The case is 

 totally distinct from the cases of Annulatella and Flava- 

 (jinella, both of which likewise feed on the seeds of Cheno- 

 podium. The case of Unipunctella is formed of pieces of
