220 INJURIOUS IN'SECTS 



at the sides, "while there are from six to eight transTerse 

 wrinkles on all but the thoracic and caudal segments. 



The color of the worm, when about to transform, is 

 often of a most beautiful pink or crimson. The chrysa- 

 lis is formed within a smooth cavity under ground. It 

 is of a dark shiny mahogany-brown color, shagreened or 

 roughened, especially at the anterior edge of the seg- 

 ments on the back. 



Unlike the Hog-caterpillar of the Vine, this insect is 

 everywhere single-brooded, the chrysalis remaining in the 

 ground through the fall, winter, and spring months, and 

 producing the moth towards the latter part of June. 



The moth is of a brown-gray color, handsomely varie- 

 gated with light-brown, and with dark deep brown spots. 

 The hind wings are pink with a dark shade across the 

 middle, still darker spots below this shade, and a broad 

 gray border behind. 



We have never found any parasite attacking this spe- 

 cies, but its solitary habit and large size make it a con- 

 spicuous object, and it is easily controlled by hand, when- 

 ever it becomes unduly numerous upon the Grape-vine. 



THE SATELLITE SPHINX 

 (Philampelus satellitia, Liirn.) 



Like the Achemon Sphinx, this insect occurs in almost 

 every State in the Union. It also bears a strong resem- 

 blance to the former species, and likewise feeds upon the 

 Virginia Creeper {Amjoelopsis), as well as upon the Grape- 

 vine; but the worm may be distinguished by having five 

 cream-colored spots each side, instead of six, and by the 

 spots themselves being less scalloped. 



In the latitude of St. Louis, this worm is found full 

 grown throughout the month of September, and a few 

 specimens may even be found as late as the last of Octo-
