Exhibitions and Notes. 



Mr. Kotinsky stated that a bit of twig and leaves received a 

 few days ago from Mr. E. H. Edwards of Kona, and labelled 

 "Giant lemon from Fiji," was found plastered by (Lecaiiiiim) 

 Coccus z'iridis (Green). Of the entire lot, only one specimen 

 was observed showing evidence of having been parasitized. Since 

 Mr. Green, the author of the species, reports the insect as one of 

 the most destructive enemies of coffee plants in Ceylon, he was 

 inclined to regard the discovery of its establishment in Hawaii 

 with some alarm. It is true ]\Ir. Green reports that about 90 

 per cent, of the insect is destroyed by a fungus disease during the 

 rainy season. There is nothing to indicate that that useful fungus 

 was introduced with the pest into Hawaii. Mr. Green also records 

 some four species of Hymenopterous parasites bred from C. zi- 

 1 idis in Ceylon, but so little is known about the scale in Hawaii 

 that he was not even aware whether any of those parasites were 

 brought along, nor could he tell whether the scale insect parasites 

 already here will take readily to the new-comer. In view of these 

 facts, he had been commissioned by Mr. Craw to proceed to Kona 

 at the first opportunity and make the necessary investigations. 



Mr. Perkins expressed the doubt that any Lccanium could be- 

 come a serious pest on these Islands in view of the large variety 

 of their enemies introduced and established here by Mr. Koebele. 



Mr. Kotinsky also reported the finding of (Lccanium) Coccus 

 mangifcrae (Green) in injurious numbers upon the Alfons (In- 

 dian) variety of mango in the Moanalua Gardens. Mr. Craw 

 believed that he had observed the same scale upon trees in Mr. 

 Giffard's yard; Mr. Giffard thought that such would not be im- 

 possible, since he has frequently exchanged plants with the Gar- 

 dens. 



Mr. Giffard exhibited a female of what is probably a species 

 of Microcentrum collected in his house on October 24, 1905. This 

 is the first specimen of the species to have been collected in the 

 Hawaiian Islands, which would indicate that it is a recent intro- 

 duction. 



Mr. Craw stated that he is keeping some 250 boxes or oranges 

 from Japan in quarantine, the oranges being infested with some 

 six species of scale insects. Mr. Perkins advised the breeding of 

 parasites from these scales and releasing them, as he had already
