under the magnifier is a beautiful object, being delicately sculptured with 

 radiating grooves, and with dots in concentric lines. The young larva is 

 hatched two or three days after the egg is laid, and at first is light greenish, 

 or yellowish green, with darker shading across the middle of the body. 

 The body is now thinly set with black hairs, arising from minute black 

 points. Eight or nine days after hatching, the larva is full fed, having 

 meanwhile moulted four times. It is now a smooth-bodied caterpillar, 

 with the ground color, a light gray or dull white, marked with black 

 dashes on the sides of each segment, and with shadings of salmon pink. 

 The full-grown larvae enter the ground for transformation, excavating for 

 themselves in the surface soil, to the depth of two inches, a tubular 

 burrow, the lining layer of which is rendered firm by the application of 

 the juices from the caterpillar's mouth, and the opening closed by a thin 

 layer of particles of soil united in the same manner. These cases may, 

 with moderate care, be removed entire from the soil." 



"The transformation to the pupal state is now effected. The insect 

 in this state has the pointed oblong form and brown color of the pupa of 

 moths in general, slight characteristics being found in the outlines of the 

 apex of the head and tip of the abdomen. The exact duration of the 

 pupal state was not observed. However, it may be said that the insect 

 was underground about twelve days; at the end of this period appearing 

 as a moth." 



The moth also is described, but as that is comparatively well known 

 we will not reproduce the description. 



Prof. Popenoe says in addition to the descriptions : "Four broods of 

 the insect have been traced the past summer, and some of the moths of 

 the last brood are now flying. It is not certain, however, that they will 

 generally leave the pupa before Spring ; and further observation is needed 

 to determine the manner of hibernation. " 



"The larva was seen at Manhattan in 1886, in moderate abundance, 

 and the moth was bred that year. Previous to 1886, the writer has seen 

 this moth only from the southwest, having collected numerous specimens 

 at La Junta, Colorado, in 1881." 



"Specimens are reported by collectors from Arizona and Texas, the 

 species having been described from the last-named region by Grote and 

 Robinson, in the transactions of the American Entomological Society, 

 Vol. II, for 1868-69."
