ing of the tube, waiting for passing insects. ' They will dart 

 back into their tubes when alarmed. Hentz reported this spe- 

 cies from Massachusetts and Alabama. I have made special 

 investigations upon the species in North Carolina, with a view 

 to establish, if possible, the identity of Hentz's species fatifera, 

 and the correctness of his statement that it uses the tube habitu- 

 ally at all seasons. The species can be easily recognized from 

 Hentz's description. The one I find here is the piceous variety, 

 which Hentz reported from Alabama, and not the typical form 

 from Massachusetts. 



TEMPERATURE AND RAIN-FALL AT VARIOUS 

 STATIONS IN NORTH CAROLINA. 



J. A. HOLMES. 



The accompanying tables of temperature and precipitation at 

 stations in North Carolina include the results of all observations 

 accessible, collected from different sources. As a basis for the 

 whole, I have made use of the MS. records of the Geological 

 Survey of North Carolina, from observations made under the 

 direction of the late Professor W. C. Kerr (stations marked "a' : 

 in the tables). A few records (b) have been taken from Kerr's 

 Report on the Geology of North Carolina, 1875 (pp. 71 and 

 83); a considerable number have been taken from the Smith- 

 sonian Temperature Tables, 1876, and the Smithsonian MS. 

 records '(c), and from the published reports or MS. records of 

 the United States Signal Service (d). A few records (e) have 

 been furnished by the North Carolina Agricultural Experiment 

 Station at Raleigh. 



Except where otherwise noted the observations have been 

 taken daily at 7 A. M., 2 p. M., and 9 p. m. The daily mean 

 has generally been obtained by dividing the sum of the 7 a. m., 

 2 p. M., and twice the 9 P. M. (local time) observations by 4; the 

 monthly, by dividing the sum of the daily by the number of 

 days in the month. Temperatures for the region are averages 

 of stations in each region.
