98 THE CANADIAN ENTOMOLOGIST. 



(f) Three males and one female with four rows of dots on the 

 prunaries, and a spot near the costa of the secondaries. 

 II. As Regards the Abdomen : 



Eleven specimens are immaculate, and seventeen have longi- 

 tudinal rows of spots, 

 (a) and (b) have tlie abdomen immaculate. 



(c) Two specimens have two distinct rows of black spots on the 



under side, and no more ; two have dorsal and side rows of 

 spots, but none underneath. The rest have immaculate 

 abdomens. 



(d) One has five rows of spots, and six have the two rows on the 



under side only ; but of the latter one specimen has two 

 black dots on the back. 



(e) One (male) is immaculate as regards the abdomen ; one 



female has the five rows ; and the other has rows on the 

 under side only. 



(f) One ( 9) has all five rows ; one {^) has only the rovvs on 



the under side ; and one ( ^ ) has an immaculate abdomen. 



Of the males the usual expanse of the wings is 17 lines, but one 

 reaches 20. Of the females the usual expanse is 20 lines. 



I sent two of the moths to Washington, and Dr. Dyar kindly wrote 

 me word that the insects belong to the species Antigone of Strecker. 

 Mr. Lyman also submitted a pair of the same brood to Mr. BeutenmuUer, 

 who said thar he had seen Strecker's types at Reading, Pa., a few days 

 before, and that the species was certainly Antigoiie. Very well. 



In Smith's list the 6". congrna of Grote is given as a synonym of 

 vS. antigone of Strecker. What does Grote say on the subject ? " On 

 my first visit to the British Museum I examined Walkei's types, and 

 made the following descriptions of his specimens " .... 



Here follows a description that exactly fits my group (c). And he 

 adds, " I was doubtful about its being North American. But very likely 

 it is a form that Mr. Strecker calls Antigone, which must join that 

 author's long list of synonyms." (Can. Ent., Vol. XV., \>. 9.) 



But Walker gives his own account of S. congrua ; and, as the 

 British Museum lists are not easily obtainable, and but {qsv of our 

 Canadian entomologi'Sts have copies of them, I ask room for the descrip- 

 tion in full.
