15. The Pretty Crambus. 

 Cranibus elegans. 



PLATES III., VIII., XII., XIV., Fig. 15. 



This insect is a very pretty little moth. When the wings are 

 folded it is readily recognized by the brown horse-shoe shaped 

 mark upon the center of its back. The whole insect is marked 

 in a rather irregular manner with brown on a white background. 

 This species is not very abundant, yet by no means rare ; it is 

 quite generally distributed over the United States. It is found 

 almost entirely upon high land and is frequently quite abundant 

 near wet springy places. The moths fly mostly in the latter part 

 of the afternoon and in the early evening. Though this insect is 

 quite common in Ithaca, none were taken in the trap-lanterns. 

 In Ithaca the adults fly during the most of July and the first half 

 of August. They fly slower than most species and with a more 

 irregular flight ; their movement is so characteristic as to be 

 easily recognized. The eggs hatch in from twelve to fourteen 

 days. 



Egg. — Creamy white when first laid, gradually turning to an orange buff 

 color before hatching. Form oval ; size .42 mm. by .30 mm. The egg-shell has 

 sixteen longitudinal ridges and numerous smaller transverse ridges. PI. XII. ,

This species is not very abundant around Ithaca, only one 

 female being taken in 1892. None were taken in the trap-lanterns.
