The head is black and shining, the V-inark well indicated, the cervicalor thoracic shield is shining light, somewhat purplish, gray, and is rathervariably marked with brown, which forms each side of the median stripeof the second thoracic segment, two irregular longitudinal dark brownpatches, darkest and widest toward the posterior margin. On eachside above the spiracle of that joint is a shorter dark patch. Nearthis there are sometimes two or three small dark rounded spots. The. A NEW WEBWORM ENEMY OF CRUCIFEROUS PLANTS. 55 spiracle of this segment is dark brown, the remainder being concolorouswith the body. The thoracic legs are more or less infuscated, and theprolegs are nearly concolorous with the venter. The entire surface ofthe body is sparsely covered with moderately long yellow and lightbrown hairs, proceeding from small and shining piliferous tubercles. The anal shield bears from ten to a dozen round purplish sj)ots, themost posterior one the largest and standing alone, the remainder form-ing a subcrescentic pattern. The length when in natural position at rest is about 13mm and whenextended 15mm, the width being a trifle more than 2mm at the widestpart. The pupa.—The pupa is moderately shining light yellowish brown incolor and the surface is covered with a light pruinose bloom. The eyesare dark brown, varying to black and the dorsum is mark
