scurely marked Anopheles maculipennis, also frequently 

 found in dwellings in this State. 



Fig. 14— Larva of yellow fever mosquito (Slesomyia fasciata) when hatchins- 



Stegomyia fasciata (The Yellow Fever Mosquito). — From 

 a barrel of water near Gary on Straight Creek I took, Octo- 

 ber 21, 1911, a larva that appears to belong here. It was 

 late in the season to look for adults, though they occur until 

 after frost at Lexington. The adult, as stated in a bulletin 

 published in 1901 (Ky. Experiment Station, No. 96) 

 is a common household insect in Kentucky, breeding close 

 about dwelHngs in buckets, barrels, troughs, etc. If we 

 should ever be visited by yellow fever refugees this little 

 pest stands ready to do its part in spreading the disease. 

 Its disposition to sting the wrists, backs of hands and 

 ankles is well known, and may suggest a possible relation 

 between it and the spread of pellagra.
