apparently lost sight of, and he asked Mr. Smith if he had learned 

 anything' of this interesting phase of the matter. 



Mr. Smith replied that he had heard nothing of this ladybird para- 

 site. He stated also that Eh. rent red is is not easily established and dies 

 ont very readily, and is also preyed upon by Chrysopas. He thought 

 Mr. Koebele in his report of conditions in 1893 had not given sufficient 

 credit to the native twice-stabbed ladybird, everywhere present in 

 abundance. 



Mr. Howard, referring to the shipment of supposed introduced Aus- 

 tralian ladybirds from California to Washington by Mr. Snow, collected 

 and transmitted at the request of Mr. Smith, described the character of 

 the material transmitted, which contained no Australian species what- 

 ever, but were all American species, no less than three of them being 

 plant-feeders. After surveying the whole held, however, we can not but 

 admit that one at least of Mr. Koebele's later importations has been of 

 great benefit. That species is Gryptolcemus montrouzieri, which was 

 imported, into Hawaii for the purpose of ridding the coffee plantations 

 of Pulvinaria psidii. The latest communications which he had received 

 from Hawaii, both from the commissioner of agriculture and lands and 

 from Mr. W. G. Wait, of Kailua, indicate that the expected work lias 

 been thoroughly accomplished. Through the kindness of Mr. Craw, 

 specimens of this beneficial ladybird in the larval state have been 

 received at the Department of Agriculture and have been placed upon 

 orange trees affected by mealy bugs. The ladybird larvae have taken 

 hold energetical^ and are now in flourishing condition, while the mealy 

 bugs are fast disappearing. 



Mr. Smith gave an instance of the efficiency of this Cryptohemus 

 against mealy bugs, and stated that it is not adapted to out-of-door life 

 in this country, but will accomplish good work in greenhouses. 



In reply to a question from Mr. Fletcher, Mr. Smith said that he had 

 not observed ventralis feeding on fungus, but he was firmly of the belief 

 that it has this habit. 



Mr. Hopkins presented a paper entitled " Insect Enemies of Forest 

 Trees." The paper has been published in the Canadian Entomologist, 

 Vol. XXVIII, No. 10, pp. L>13-250, October, 1890, and in accordance 

 with the policy adopted by the association can not be reprinted in its 

 published proceedings. 



In discussion Mr. Fletcher said that the subject covered by Mr. Hop- 

 kins is of great importance to < 'anada on account of the large lumbering 

 interests there. He stated that the experience which Mr. Hopkins had 

 described following forest fires is a common one in Canada. The two spe- 

 cies most injurious in Canada under these conditions are Monohammus 

 scutellatus Say and .1/. confusor Kirby. He gave an account of the habits 

 of these species, mentioning, among other interesting points, the fad 

 that they often go into the hard wood the first year, and that the larval
