182 FORTY-SECOXB REPORT ON THE StATE MuSEUM. [40J 



collar on the first segment is j^ale orange, dotted with black. The second 

 and third segments have a transverse series of black dots, but without an 

 orange band; the other segments have each a broad, central, orange 

 band, with four narrow black bands on each side, counting those that 

 border the orange. From each of the black dots shown in the enlarge- 

 ment, a long white hair is given out, which is longer than represented 

 in the figure. Below the line of the stigmata (breathing-pores) is a 

 series of white spots on segments four to nine, just behind the orange 

 band ; a large white spot rests on the incisure of the tenth and elev- 

 enth segments. The legs are orange at their base, and black exter- 

 nally and at their tip, except the anal pair, which are orange dotted 

 with black. 



The caterpillar may be found upon the Ampelopsis from the first of 

 June until the first of August — its long continuance making it quite 

 difficult to control its operations either by hand-picking or by insecti- 



cidal applications. 



The Flight of Alypia. 



The moth is a day-flier, and has, of late years, become very com- 

 mon in Washington park, Albany, where almost every year it may be 

 seen flitting abundantly about the blossoms of Deutzia gracilis, upon 

 which it delights to feed. Not unfrequently from ten to fifteen of the 

 prettily and conspicuously marked creatures may be seen hovering 

 over or momentarily alighting upon a single plant. It flies as early 

 as 9 o'clock in the morning and continues until 6 p. m., or later. Com- 

 mencing to appear as early as the middle of May, it remains until 

 the middle of June. I have also observed it, in the same locality, 

 flying abundantly, on May twenty-eighth, about the flowers of the 

 bush-honeysuckle, Diermlla Japonica. 



The Eudryas Caterpillar. 

 Both the caterpillar and the imago of Eudryas grata are rare; the 



former is so seldom met with that 

 collectors experience difficulty in 

 procuring specimens from which 

 they may rear the beautiful moth 

 for their cabinets. The caterpillar, 

 a, in Fig.lO, is characterized by three 



black bands on each side of the cen-
