The cabbage-moth. — Complaints liavo been made by correspondents 

 iu New York and Kew Jersey of injuries done to cabbaties in the autumn 

 by the attacks of a small, green caterpillar, that eats holes in the outer 

 leaves, sometimes riddling- them like a seive. The caterpillar is about 

 0.35 of an iuch in length, cylindrical in form, thickest hi the middle, 

 and of a g'reen color. The moth produced from it was named Flutella 

 liinhipcnelki^ by Clemens, (Fig. 5,) and is described by Dr. Fitch iu the 

 Fig. 5. New York State Agricultural Report for 1S53, page 874, as 

 cgggiiiSX".- the cabbage-moth, Ccrostoma hrassicella, and is closely allied 

 .,^^___^_, to, if not synonymous with, Phitella zylontcUa, Linn., in 

 ^^i&t'" Europe ; and if so, is another imported insect. AVhen dis 

 _---^y_^, turbed, this caterpillnr drops from tho plant, but suspends 

 '^^^P?^"' itself by means of a silken thread. There are at least two 

 I \^ broods in one season in the more southern States. In the 

 /i "^ fall of 1870 it was very plentiful iu parts of j\Iaryland, rid- 

 dling- the cabbages verj^ seriously. The pupa is formed in a beautifully 

 constructed cocoon, woven of silk-like delicate open net-work on the 

 leaves, and remains a pnpa in the cocoon only a few days. The perfect 

 insect is a small moth, with the upper wings of an ash-gray color, 

 freckled on the disk and apex with black dots, and having a white 

 stripe on the inner margin ; the imder- wings are ash-gray. 



Wtishing- or S3'ringing the plants with whale-oil soap-suds or strong 

 solutions of tobacco- water would no doubt be of use, if they did not 

 give the heads a disagreeable flavor, or if the cabbages were subjected 

 to a thorough washing before using. The insect is subject to the attacks 

 of a minute ichneumon lly; and the t-\Vo spiders, Tlurldloii hrassicw and 

 Jii/pophylliim, mentioned by l)r. Fitch in his last report in connection 

 with the white cabbage butterfly, will also, no doubt, b(^ of service in 

 destroying the small caterpillar. 



CHEMICAL NOTES. 



By Ryland T. Bkown, Chemist. 



The laboratory is now emiiloyed in the analysis of commercial manures, 

 with a view of determining the relative value of these commodities, that 

 those Avho purchase and use them may have something to guide them 

 in their choice. These analyses will appear from year to year in the 

 annual reiiort of the Department. But little work, other than this, has 

 been done since the last report, and of that little scarcely any is of suf- 

 ficient general interest to justify publication. A specimen of caleareon.^
