finely punctate, highly polished, the pleura with a row of fine black dots, 

 and an extra dot outwardly ; connexivum acute, the intersegmental 

 sutures indented and marked with a black dot. Tergum black, the 

 sutures, exteriorly, with a double black spot. Length to end of abdomen, 

 9 to lo mm. Width of pronotum, 5^ to 6 mm. A pair of these insects 

 taken in Massachusetts have been kindly given to me by Mr. A. H. 

 Kirkland. Other specimens have been sent to me for examination from 

 Rhode Island, Pennsylvania, and the District of Columbia. I have found 

 it once, July 4, in a sandy pine woods district in southern Maryland. 

 Only a few specimens have thus far been reported. It seems to be of 

 rather uncommon occurrence." 



GRAPTA INTERROGATIONIS. 



BY ARTHUR J. SNYDER, N. EVANSTON, ILL. 



Under the title " Notes on Vanessa Interrogationis," in the February 

 number of Can. Ent., Mr. W. F. Fiske gives some interesting statements 

 corresponding to observations made here. I kept bait for moths on the 

 trees in and near my yard from the beginning of the year 1896, and cap- 

 tured Noctuids during January, February, and March. 



Diurnals came to the bait for the first time on April 12th. Vanessa 

 Antiopa led the van, followed closely by the Graptas and Pyrameis 

 Atalanta. In a few days Ijiterrogationis and Atalatita were abundant. 

 Grapta Comma appeared on the 17th of April. 



April 24th I made the following note in my record : " Previous to 

 this date all the Grapta I?iterrogationis were hibernating specimens and 

 of the form Fabricii. This evening (my observations were made from 

 four p.m. 'till dusk) all were of the dark form Umbrosa, but also all old 

 hibernating specimens." 



On the 25th both Ufubrosa and Fabricii were seen. During the 

 last of April and first part of May Graptas were exceedingly abundant. 



On May 7 th saw the first Grapta depositing eggs on elm. Captured 

 the $ and found it to be Umbrosa. A single butterfly procured from 

 these eggs was of the form Umbrosa. 



Soon the eggs and larvae of Graptas were abundant on the elm trees 

 and shrubs, especially on the low branches of young trees. One could 

 hardly turn over a bough of one of these without finding several larvse.
