A specimen from Louisiana agrees very well with Wiedemann's description, 

 though it does not have the dark abdomen as Say describes. 



METEOROLOGICAL SUMMARY FOR THE YEAR 1886. 



PREPARED BY PROF. F. H. SNOW, OF THE UNIVERSITY OF KANSAS, FROM OBSERVA- 

 TIONS TAKEN AT LAWRENCE. 



The year 1886 was marked by an excessively cold January, a long, hot summer, a 

 dry atmosphere, light winds, and clear skies. But the most remarkable character- 

 istic of the year was the very light rainfall of its second half. Up to the 1st of July 

 the rainfall was only 1.79 inches below the average, but for the remainder of the year 

 there was a deficiency of 9.23 inches, the total precipitation being less than half the 

 normal amount. Although the total rainfall was much less than in any previous year 

 of our record, the copious rains of the first six months secured good crops of wheat 

 and half crops of corn in the districts most seriously affected by the drouth. 



TEMPEKATUEE. 



Mean temperature of the year 52.96°, which is .04° above the mean of the eighteen 

 preceding years. The highest temperature was 105°, on August 16th; the lowest was 

 18° below zero, on the 9th of January, giving a range of 123°. Mean at 7 a. m., 47.13°; 

 at 2 P.M., 62.16°; at 9 p.m., 51.28°. 



Mean temperature of the winter months 23.33°, which is 5.88° below the average 

 winter temperature; of the spring 54.57°, which is .96° above the average; of the 

 summer 76.80°, which is .96° above the average; of the autumn 57.17°, which is 3.39° 

 above the average. 



The warmest month of the year was July, with mean temperature 79.54°; the 

 warmest week was August 11th to 17th, mean 86.93°; the warmest day was August 

 16th, mean 90.62°. The mercury reached or exceeded 90° on 53 days, (13 more than 

 the average number,) viz.: two in May, three in June, twenty-one in July, eighteen 

 in August, and nine in September. There were five days on which the temperature 

 exceeded 100° — one in July and four in August. 



The coldest month was January, with mean temperature 14.32°; the coldest week 

 was January 6th to 12th, mean temperature .61° below zero; the coldest day was 

 January 8th, mean 12.75° below zero. The mercury fell below zero on 16 days, of 

 which 10 were in January, 3 in February, and 3 in December. 



The last hoar frost of spring was on April 27th; the first hoar frost of autumn 

 was on October 1st; giving an interval of 155 days, or over 5 months, entirely with- 

 out frost. This is precisely the average interval. 



The last severe frost of spring was on April 5th; the first severe frost of autumn 

 was on the 27th of October; giving an interval of 203 days, or nearly 7 months, with- 

 out severe frost. The average interval is 198 days. No frosts during spring and 

 autumn caused damage to crops of grain and fruit, but the low temperatures of Jan- 

 uary were universally destructive to peach buds.

The entire rainfall, including melted snow, was 24.25 inches, which was 11.02
