Asterochiton coroUis, new species 

 Pupa-case: — Size 0.90 mm. by 0.61 mm.; shape elliptical with 

 the caudal end truncate; color dark brown. The wax .secretion of 

 the dorsum, as observed from somewhat imperfect specimens, con- 

 sists of three separate systems as follows ; first, a continuous mar- 

 ginal fringe extending entirely around the case, the rods of which 

 are short and loosely .ioinod. projecting directly toward the leaf 

 to about one-half of the distance from the margin to the leaf. 

 Second, a series extending continuously around the case just within 

 the margin. The rods of this system are long, white and closely 

 coalesced at their bases and extend upward for the greater part 

 of their lengths then outward over the case, separating into ribbon- 

 like structures at their extremities. Third, a series of short, thick 

 rods arranged in groups which arise mesad of the second svstem 

 and which project toward the center of the case. In addition to 

 the dorsal wax the pupa case secretes a high vertical fringe of 

 wax on which the case rests. The submarginal area bears a row 

 of large, conical, papilla-like pores the bases of which are clo.se 

 together, the pores themselves measuring about 0.02 mm. in 

 length. These pores undoubtedly secrete the long ribbon-like wax 

 .structure. On the dorsum jtrnpcr are irregularly shaiied. con- 

 spicuous, pore-like oiicnings which are arranged in groui)s. the 

 outer margins of which conform to the general curve of the case. 

 These groups are found as follows: two in the cephalic region con- 

 sisting of fourteen pores each, two in the thoracic region containing 

 about twelve openings each and two in the abdominal region con- 

 taining twenty-four each. Scattered through these pores are numer- 

 ous very small circular pores also two pair of similar circular pores
