second year's crop; in this case they seemed to relish the young green leaves, 

 while in the older plants they 'would hardly touch anything but the flowers 

 and the lining of the stems. 



The following is a description of the mature larva : — 



Length 070 inches. General color dirty green above, yellowish on sides 

 and beneath. Head deep shining black, emarginate posteriorly ; second 

 segment with a similarly shining black trapezoidal shield above, divided in 

 the middle by a fine suture, the rest of the segment greenish yellow, with 

 three small black warts on each side; remaining segments, except the 

 eleventh, dirty green above, yellowish on sides and beneath; eleventh seg- 

 ment entirely dull yellowish ; all the segments, except the first two, have four 

 dorsal, eight lateral (four on each side), and four ventral, shining black warts, 

 each emitting a fine hair, black tipped with white, — some of the ventral warts 

 are absent, where their place is occupied by the feet; dorsal line dark green, 

 fine, rather indistinct. Legs shining jet black ; prolegs dirty greenish yellow ; 

 three pair of the former, five pair of the latter — sixteen feet in all. 



Young larva : — Length 0-30 inches. Similar in all respects to the mature 

 larva, except that the color of the first four segments is rather darker, and 

 of the remainder more yellowish. 



Pupa: — Length 040 inches; dark brown, abdomen a little paler; en- 

 closed in a slight silken cocoon inside the hollowed stem. 



The insects remained a fortnight in the pupa state, the moths beginning 

 to appear on the 1st of August. They proved to belong to the genus Depres- 

 saria, of the family Gelechidce, group Tineina. A full description of the 

 characters of this genus is given by the late Dr. Clemens in his article on 

 '•American Miero-Lepidoptera," (Proceed. Ent. Soc. Philada., vol. ii., No. 2, 

 page 124). The most striking peculiarities are the indentation of the hind 

 margin of the secondaries toward the anal angle, the brush-like second joint 

 of the labial palpi, and the flattened abdomen with its projecting scales at 

 the sides. 



But very few American species of this genus h»ve yet been described; 

 though no doubt many will be found when collectors begin to turn their 

 attention more particularly to the Micro-Lepidoptera ; at present most of us 

 find that we have quite enough to do in trying to investigate the Macros, the 

 field in this department being large enough to occupy the attention of an 

 immensely increased number of Entomologists for years to come. The 

 species. before us has evidently not been described by any American writer, 

 nor do we find that it corresponds to the brief description of any of the 

 British species contained in Mr. Stainton's Manual. Mr. Curtis relates that 

 D. applana, depressella , and daucella, affect carrots and parsnips in England,
