them. It thus differs from an allied species, BlacUsta coffeella G. M., 

 which is said to be very injurious to coffee [Coffea arahica) in the West 

 Indies (Nietner). 



150. Gracilaria theivora Walsingham (Plutellidse) . — Reported as 

 attacking the tea plant [Camellia theifera) in Ceylon (Green). 



151. Gelechia cerealella Oliv. (PlutelHdse). — The caterpillar of this 

 moth has been reported as destructive to stored maize [Zea Mat/s) in the 

 Himalayas. It is a well known pest in the United States, where it does a 

 good deal of damage by tunneling into stored maize seed. 



153. Setomorpha rutella Zeller (Tineidae). — The caterpillar of this 

 moth has proved destructive to bales of country blanketing in Calcutta. 



153. Tinea pellionellaJAnn. (Tineidse). — The caterpillar of this moth 

 is a minnte creature that protects itself in a case much like the case made 

 by TsycTiidae caterpillars. It has been noticed as very destructive to i 

 woollen material in Calcutta. It is a well-known pest in Europe and 

 America. 



154. Undetermined Miceolbpidopterous caterpillars have been 

 reported as follows : — (1) a minute Tineid caterpillar, which attacks stored 

 dhanoY unhusked rice [Oryza saliva) in Calcutta, spinning the grains to- 

 gether into a web : (2)the caterpillars of a small undetermined moth, which 

 has been supposed to be one of the Pyrales, reported as very injurious to 

 the leaves and flowers of the mustard crop [Brassica) in Assam, where the 

 insect is known as b/izir : (3) a minute caterpillar, said to attack the 

 lentil plant [Ervum Lens) : (4) a species of Tineina, said to tunnel into the

157. Teycolyga BOMBYCis Becher (Museidse-TachinEe).— Parasitic on 

 the mulberry and eri silk-worms of Bengal and Assam. It is much like 

 a big house fly, and is most destructive in silk-rearing establishments, 

 where it often destroys a large proportion of the silk -worms. Closely 

 allied forms have been reared from many species of caterpillars in India, 

 and they are believed to be about the most effectual check which exists 

 for preventing the undue multiplication of defoliating caterpillars of all 

 kinds. A very similar insect is parasitic on the locust of North- Western 

 India {Acridium peregrinum) .
