114 PEACH. ROOT THE BORER. PUPA. MALE MOTH. 



a short obtuse projection with minute hairs at its tip. The antennae are coni- 

 cal and three-jointed, the last joint minute and the second one armed exterior- 

 ly with a short bristle. At their base en the under side of the head, are three 

 or four dilated punctures. There are a few scattered brown bristles upon the 

 head and also upon each of the other segments; those on the third, fourth, 

 twelfth and thirteenth segments, are arranged in transverse rows, and on the 

 other segments they are placed symmetrically and arise from faint, smooth, 

 wart-like spots. The second segment is tinged with yellowish above and has 

 a breathing pore upon each side. The two next segments are somewhat short- 

 er than the following ones and are destitute of breathing pores. These three 

 segments each bear a pair of conical legs ending in a black polished claw. The 

 remaining segments except the two last show a faint stripe, at least posterior- 

 ly, upon the middle of the back, and each has also a transverse impressed line 

 in the middle and a breathing pore upon each side. The two last segments, 

 which perhaps should be regarded as one double segment, are narrower, short- 

 er, and retractile, shutting into each other and into the segment forward of 

 them, like the joints of a telescope. Beneath is a pair of prolegs upon the 

 seventh and three following segments, which scarcely protrude from the gene- 

 ral surface, but are very perceptible from their soles being furnished with two 

 transverse rows of minute black hooks, about twelve hooks in each row; and 

 the last segment has a single shorter row of six similar hooks upon each side. 

 The young worm is quite similar in its details to the mature one; its breath- 

 ing pores upon the second and the twelfth segments, however, are much larger 

 and more obvious than the intervening ones. 



The Pupa enclosed within its follicle is at first white, the wing and leg sheaths 

 and the thorax being slightly tinged with tawny yellow. The breathing pores 

 form a row of tawny dots along each side of the abdomen, each segment of 

 which has a row of little sharp-pointed teeth on its anterior and a second short- 

 er row of smaller ones on its posterior margin, extending half way around, 

 from one row of breathing pores over the back to the opposite row, these teeth 

 being of a pale, tawny color, and directed backwards. The three apical rows 

 of these teeth, however, have no intervening rows of smaller ones. At the tip 

 is a row of eight larger teeth extending entirely around. It is by means of 

 these teeth that the pupa when ready to disclose the winged fly crowds itself 

 forward, out of its follicle. All the teeth become longer and more sharp-point- 

 ed as the pupa approaches maturity, and the whole of the surface now assumes 

 a pale tawny yellow color, with a darker ring at each of the sutures. 



The mature insect, like most of the species of butterflies and moths, varies 

 considerably in its size. It measures from one-half to three-fourths of an inch 

 in length, and the wings when extended, are from 0.80 to 1.30 across, the fe- 

 male being more variable in its size than the male and furnishing both the 

 smallest and the largest individuals. The wings of the female also measure 

 more than those of the male when their bodies are of equal length, the more 

 thick and heavy body of the female plainly requiring larger wings to sustain it 

 in the air. 



The male is of a deep steel blue color, with various sulphur yellow marks, 

 and has a glossy lustre like that of satin. The antennae are black, less than 

 half as long as the body, abruptly curved outwards at their tips and densely 

 fringed along their inner sides with numerous fine short hairs, with a slight
