lOlJf'] Animal Life of North Carolina 79 



Of Butterflies our list records about 115 species, and the 

 records are from numerous localities over the state. Raleigh 

 and Tryon lead with from 80 to 89 species. Cranberry and 

 Southern Pines show 58 to 65 species. Localities showing from 

 20 to 32 species are: Beaufort, Lumberton, Goldsboro, Blowing 

 Rock, Hendersonville and Andrews. These localities are suffi- 

 ciently scattered and include a sufficiency of species to give us 

 a reasonably satisfactory knowledge of the distribution (both 

 geographical and seasonal) of most of the species. With the 

 Butterflies our knowledge is if anything more nearly complete 

 than for any other group of insects, though it is a relatively 

 small group of relatively conspicuous insects, hence the data does 

 not involve as laborious work as with some of the other groups. 



Recorded from whole state 38 species. 



Mountains only 12 species. 



Westward but not confined to mountains 13 species. 



Coast mainly 2 species. 



Eastward but not in mountains 14 species. 



Local and Scattering 28 species. 



Here, as in the group containing the grasshoppers, we find 

 that a very considerable portion of our species show a more or 

 less definitely marked area over which they may occur. 



(5) The True Flies comprise another very extensive group, 

 many of which are small and delicate, hence their study presents 

 special difficulties. But they are of much economic importance, 

 especially in the light of recent discoveries of the part which the 

 blood-sucking and house-inhabiting species play in the spread 

 of human diseases. From the standpoint of Medical Entomo- 

 logy this is the most important group of all, so far as present 

 knowledge goes. The group is quite well divided into a large 

 number of families, a few of which have been studied to some 

 extent, the Horse-fly family perhaps the most thoroughly of all. 

 Of this family 41 species are on record for Raleigh, and about 

 28 each for Southern Pines and Havelock, with lesser numbers 

 from a host of other localities. 



The Mosquito fauna of the state is not yet well known, 

 though there are indications that the present activities in health 

 work will sooner or later give us some substantial knowledge of 

 our forms and their distribution. Out of a fauna probably
