INSTITUTE, PUSA, FOR 1919-20 81 



Another Tortricid larva has been found to bore into 

 apple fruits at Shillong but can hardly be described as a 

 pest, as it is not common as an apple-borer and seems 

 merely to excavate a small chamber in the core without 

 injuring the pulp of the fruit. This is the larva of 

 Ulodemis trigra/pha, Meyr., which has also been reared at 

 Shillong from a larva feeding on flowers of Colquhounia 

 coccinea. The stages of this species also will be found 

 figured in Entomological Memoir, Vol. VI, Part 9, tab. 

 LVIII, fig. 2. 



A new and serious apple-pest was found at Shillong in 

 October 1919 in Ptochoryc-tis rosaria, Meyr., a Xyloryctid 

 moth whose red larva eats the bark of young apple twigs 

 under cover of a silken tubular gallery. This insect has 

 hitherto been known only from Bhutan. From a larva 

 brought to Pusa the moth emerged in March. At Shillong 

 the moths probably appear later in the year, as there seems 

 to be only one brood on apple annually. The stages of this 

 pest also are figured in Entomological Memoir, Vol. VI, 

 Part 9, tab. LXIII, fig. 1. 



An interesting and unexpected find on apple at Shillong 

 in May and June, 1920, was Helo'pellis theivora, the so- 

 called " Tea Mosquito " bug, which in this case was found 

 sucking young shoots of apple. 



Specimens of Brahmina coriacea, Hope, Holotrichia 

 sp., and of a third undetermined Melolon thine beetle were 

 received from the Superintendent of the Kumaon Govern- 

 ment Gardens, Ranikhet, as damaging fruit trees. 

 Another Melolonthine, a species of Microtrichia, was 

 received from Solan as damaging fruit-trees. 



Life-histories of Insects. Besides the various insects 

 named above, more than 150 different lots of insects have 

 been reared during the year and observations made on life- 

 histories' and habits. In a Report of this nature it is only 

 possible to mention a few of these even by name. 



(1) Achroia grisella, Fo. (Galleriadse) (Plate VII, fig. 

 2). During the last two years^this wax-moth has occurred 

 regularly at Pusa in hives occupied by the Indian Bee
