Cervical shield brown, paler than the head, broadly shield-shaped with 

 quite a broad median white line, a few rather long hairs and several 

 shorter ones scattered over the surface. The remainder of the pro- 

 thorax, the meso- and meta-thorax same color as the rest of the body. 

 Legs pale, three-jointed, supported by dark brown chitinous frame- 

 work ; several short rather stout hairs on each segment ; a whitish, 

 elliptical, striated lobe arising beside the single brown tarsal claw. 

 Segments four to eleven, all similar, skin wrinkled, somewhat papillose, 

 a few scattering hairs over each segment ; on the lateral margin of each 

 segment is a long stiff hair just posterior to one and sometimes two 

 smaller and shorter hairs. Dorsal shield of posterior segment semi- 

 circular in outline, dark brown, finely sculptured so as to produce num- 

 erous hexagonal pitted areas much resembling the markings on the 

 eggs; several strong marginal hairs and two sub triangular processes 

 near the posterior end. A single fleshy proleg. 



The larva agrees almost perfectly with Prof. H. Carman's descrip- 

 tion of the larva of D. 12-punctata as given in Psyche, Vol. VI, p. 48. 

 The only special difference I would note is in the description of the dor- 

 sal shield of the posterior segment which he describes as follows : " Dor- 

 sal shield of posterior body segment nearly circular in outline, brown, 

 with numerous minute black specks, slightly rimmed at posterior mar- 

 gin, and in young examples obscurely bituberculate ; furnished with 

 several strong marginal hairs, and with four minute, striate, centrally- 

 placed spatulate appendages." 



Pupa. — Whitish or straw-colored. Length .4 mm., width .2 mm. 

 Scattered brown hairs over the body arranged as follows : six on the 

 head arranged in three transverse pairs, one pair close to the base and 

 just cephalad of the antennos, one just caudad of the antennne, and one 

 near the meso-dorsal angle of the eyes ; ten on the prothorax, one pair 

 on the anterior margin, one pair near the lateral margin, and one pair 

 near the posterior margin, a pair just anterior and a larger pair just 

 posterior to the middle near the mesal line ; an arched row of four hairs 

 each on the meso- and meta-thorax; a pair in the middle and one on 

 each side of each abdominal segment ; last three segments with another 

 pair slightly anterior to and more widely separated than the median 

 pair ; last segment also with a pair between and a pair in the bases of 

 the caudal spines, and another pair just anterior to the lateral pair. 

 Caudal spines usually slightly curved, brownish at tips. Each femur 

 with three hairs near the extremity. Wing pads clear white, covering 

 the proximal part of the posterior femor. Antennae curving outward
