OF WASHINGTON, VOLUME XV, 1913 169 



Dr. Hopkins called attention to the probable introduction 

 of a destructive European Scolytid into this country, specimens 

 of Myelophilus piniperda L. having been recently sent to him for 

 identification by Dr. T. J. Headlee, of the New Jersey Experiment 

 Station, with the statement that it had been found boring in living 

 shoots of pine in one locality of his state. 



Dr. Hopkins also mentioned a record by Dr. Leconte in 1868 of 

 this insect from New York, but it had never been known whether 

 it was collected in the field, or had come from some collection of 

 foreign insects through a mistake in labeling. 



FOREST MALARIA. 



BY DR. A. LUTZ, Rio de Janeiro. 



I have received from Doctors Knab and Dyar answer to my 

 statements concerning the transmission of malaria by wood mos- 

 quitoes, in which they not only refuse to be convinced but repeat 

 their accusations of overlooking and misunderstanding elementary 

 facts. I only want to make plain, why I have protested and leave 

 it to the members to decide, if their way of arguing ought to be 

 approved. 



In order to suit their theory Galli-Yalerio must have mistaken 

 another anophelid for Myzomyia lutzi, though this is an extremely 

 characteristic species which can be distinguished from all others 

 by a glance at the scutum. Lutz and Chagas must have over- 

 looked the presence of other anophelids at the places of their ob- 

 servations. Now Lutz and Chagas might be expected to know 

 anophelids, as they worked with them for years and together in- 

 dicated most of the Brazilian species. Both made formal dec- 

 larations and I have a written statement from Dr. Chagas to the 

 point that he looked carefully for other anophelids while he treated 

 the epidemic on the spot. At that time he did not know me, nor 

 my paper and made his observation quite independently. Those 

 facts are considered of no account, because Dr. Knab found in 

 Central America other anophelids, in localities which he takes to 

 be similar. He even mentions Amtplnies eiseni, a species which 

 has never been found in the states of Rio and Sao Paulo where the 

 observations were made. I am also accused of overlooking that 

 men are men, and it is stated that the men must have got away at 

 night and infected themselves elsewhere. I have already declared 

 that thev lived manv miles awav in the woods and there was no
