quitoes showed no corresponding decrease in numbers. In the investi- 

 gations of Nuttall. Cobbett and Strangeways-Pigg, these well-known 

 authorities found many mosquitoes btit no cases of malaria, in districts 

 where the disease had been previously very prevalent. Later Theobald 

 discovered a genuine case, contracted in England. 



In conversation with residents of Keremeos, we have heard of cases 

 of malaria in that part of the country. However, it is unnecessary to do 

 more than mention this fact, without further discussion, for the subject 

 can be better dealt with l^y a medical man. 



1 gi\e a short description, taken from Patton and Cragg, of A puncti- 

 pennis and A maculipennis, so that the two species may l)e readily dis- 

 tinguished. 



Anopheles punctipennis, say. Palpi with two indistinct greyish 

 bands, and apices sometimes grey. Thorax chestnut brown. Abdomen 

 brown with golden hairs. Legs brown, except coxae, knees and tips of 

 tibiae, which are yellowish. Costa black, with two yellow spots, one at 

 the apex and the other at the apical third. This species is the winter 

 andpheliiie of the L'nited States. 



Anopheles maculipennis Meigen. Palpi brown, unljanded. Thorax 

 and abdomen brown. Legs brown without any definite bands. Costa 

 dark, with four dark spots, two apical and two median. It is widely dis- 

 tributed in Europe, and is a natural carrier of the parasites of malaria in 

 Italy. (Specimens of A maculipennis were shown at the meeting). 



APHID NOTES FROM BRITISH COLUMBIA. 



By H. F. Wilson, 

 Entomologist, Oregon Experiment Station. 



During the month of July, 1913, the writer had the pleasure of attend- 

 ing the summer meeting of the British Columbia Entomological Society, 

 at Vernon, P>. C, and the following species of aphids were collected dur- 

 ing the trip ; 



1. Macrosiphum stanleyi n. sp. (jii Sambucus glauca in Stanley Park, 

 V'ancouver. 



Macrosiphum stanleyi n. sp. (plate 1, figures 13-15.) 



A large, light, green species found feeding on the under side of the 

 leaves of Sambucus glauca Nutt. This species is common in the vicinity 

 of Vancouver, P). C, and Seattle, Wash. I have not collected it in Ore- 

 gon. All forms are lightly covered with a white bloom, which is much 

 more abundant on the pupae. All forms are quite active and move about 

 o\er the leaf surface when disturl:)ed.
