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



apex of the lower jaws, a short obtuse projeofion with minute hairs at its tip. The 

 antennse are corneal and three-jointed, the last joint minute and the second one 

 armed exteriorly with a short bristle. At their base on'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 yellowiih above and has a breathing pore upon each 

 side. The two next segments are somewhat shorter 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 remaiuing segments except the two last show 

 a faint stripe, at least posteriorly, 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, shorter, and retractile, shutting into each other and into the segment for- 

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

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

 face, 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 breathing 

 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 shorter row of smaller ones 

 on its posterior margin, extending halfway around, from one row of breathing pores 

 over the back to the opposite row, these teeth being of a pale tawny color and direc- 

 ted 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-pointed 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 con- 

 siderably in its size. It measures from one-hiilf to three fourths of an inch in length 

 and the wings when extended are from 80 to 1.30 across, the female being more 

 variable in its size than the male and furnishing both the smallest and the largest in- 

 dividuals. 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 wiags 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 antem.a; are black, less than half as long as 

 the body , abruptly curved outwards at their tips and densely liinged along their inner
