rEOCEEDIXGS OF THE THIRD ENTOMOLOGICAL MEETING 613 



Tlie grubs were specially active iu devouring the fruiting bodies {ven- 

 iJiecia) of the fungus, and were again observed in numbers during Decem- 

 ber 1912. The adult beetles have been found to devour with avidity the 

 nymphs and adults of the Red Spider, Teiranychus bioculatus, especially 

 bad on castor, jute and Hibiscus abehnoschus at Pusa. The sequence of 

 observations was : — 



4th September 1916. — Nymphs put on two potted bush-miilberi-y plants. (From 

 cuttings obtained from Malda). 



12th September 1916. — Apical leaves turned coppery-green and tlie stem flattened 

 .out laterally (both ways). 



14th September 1916. — Leaves became curled, malformation of shoot apparent 



new. 

 ISth September 1916. — Leaves curled distinctly, malformed apical head became 



compact. 

 19th September 1916. — Mildew, Phyllactinea cqrylea, visible on the leaves especially 



the lower ones. 



21st September 1916. — The leaves became dark coppery-green and crisp. 



23rd September 1916. — The mildew, Phyllactinea- '.Tryha, became very prominent 

 and spread to a number of leaves on the plant. 



4th October 1916. — The leaves became pale yellow and fell down. 



20th October 1916.— The growth of the affected plant from 19th September to 19th 

 October 1916 was only 3J inches. Some of the apical, malformed leaves 

 became pale yellow prematurely and fell down. The lower leaves became 

 covered profusely with the white mildew. 



i\ apical growth of the plant from 19th September to 

 1 4J inches , 



Such leaves, if served to Bomhyx mori caterpillars, cause Flacherie 

 and C4rasserie in the worms (vide letter from Mr. A. C. Ghosh, Superin- 

 tendent of Sericulture, Bengal). The apical leaves become crisp with the 

 presence of the mealy-bugs on the top shoots of •plants and contain very 

 little succulent matter iu them. It is no wonder if worms fed on such 

 leaves should develop Grasserie and Flacherie. 



At Pusa Phenacoccus hirsutus has been found by me on Monis sjDp., 

 cotton and on potted Ficus religiosa plants kept near the potted mulberry- 

 plants to stud.y the life-history of the White-fly. Close to the potted 

 mulberry-plants 'were also Eugenia jambolana, Ficus glomerata, sugar- 

 cane, paddy seedling, and Citrus decumana plants, but none of these was 

 found affected. Durmg the present winter, fully matured and gravid 

 female P. hirsutus have hibernated on Ficus religiosa plants in pots and 

 I was able f o rear one complete cycle on these plants. Late in October, 

 when Spalgius epiv.s caterpillars appeared, they cleared away whole 

 colonies of P. hirsutus on the potted mulberry as well as on Ficus religiosa 

 plantSi On mulberry plants in pots I have found Pseudococctis virgatus 

 to occur along with P. hirsutus, but the nymphs and females of the
