This susceptibility to variations in temperature causes this mosquito to be confined to certain degrees of latitude, from 40° N. to 40° S., or more exactly between the two isothermal lines of 20° C. Owing to the ease with which it may be carried from one country to another by means of ships, the species is now found in most of the regions between these limits. The accompanying map (Fig. 48) represents the distribution of. Fig. 48. The distribution of Stegomyia fasciata. S. fasciata, and it will be noticed that the insect especially occurs along the coast hues and the banks of large rivers, where the requisite conditions of humidity are fulfilled. It is absent from those regions in which the temperature during the night fahs so low as to be harmful to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hindle, Edward, 1886-.
