Miss LUDLOW has compared large numbers of Philippine Stego- 
myia with those from the Southern States of America, and finds 
them the same. All the Philippine specimens I have seen have been 
true Stegomyia fasciata or its varieties. 
There is no doubt all four are merely varieties and founded on 
purely colour and marking differences. There is no structural 
difference between them and the typical form.
