crumpled longitudinally. Unlike Red Spider, there was 

 no webbing. A single spraying with a spray composed of 

 1 lb. olene soap and six ounces of flowers of sulphur in 12 

 gallons of water proved effective. 



(23) A species of Tingidid bug was noted to cause 

 severe damage to Beta (Jasminum sambac) leaves at 

 Bankura. Spraying with simple soap solution was 

 effective. 



(24) Glyphodes caesalis was observed to attack practic- 

 ally every fruit of jak throughout Sylhet, even large fruits 

 not being immune. This insect is known as a jak-pest in 

 Southern India, but lias not been rioted before as a pest 

 north of the Madras Presidency. 



(25) Belionota prasina (Plate XVIII, fig. 2). At Surat 

 a dead mango tree was found to be full of the larvae of this 

 Buprestid beetle, and the death of the tree had apparently 

 been caused by them. The larvae were in various stages of 

 growth and apparently represented more than one brood. 

 The adult beetles began to emerge at Pusa in October, 1917, 

 and continued to do so until April, 1918. 



(26) Alcides fremitus (Plate XIX, fig. 1). This weevil 

 was observed at Dacca in July as a pest of mango. Eggs 

 are deposited in the shoots which are tunnelled by the grub, 

 whose pellets of excrement are thrown out through small 

 holes gnawed in the sides of the tunnel. Pupation takes 

 place inside the burrow, the adult weevil gnawing its way 

 out through a large hole of exit. The adult weevils are 

 found pairing and ovipositing freely on the shoots. 



(27) Chlumetia transversa. The larvae have been found 

 at Pusa tunnelling fresh mango shoots in a way very 

 similar to that of Alcides jrenatus, the frass being ejected 

 exactlv in the same manner.

(28) Giaura sceptica (Plate XIX, fig. 2). The larvae of 

 this moth were found in large numbers at Pusa in August 

 rolling the tender leaves of velvet bean. 



(29) Severe damage was observed to be caused to a crop 

 of Mung (Phaseolus mungo) at Pusa in August by the
