622 REVISTA CHILENA DE HISTORIA NATURAL 



We llave one South American collectioii of tiiis spec- 

 ies. It was taken on the stems oí Montridiordia aculeata 

 Criieg., at Georgetown, B. Guiana, by G. E. Bodkiu. The 

 pupa case, which is bright yellow in color, with two dark 

 browü stripes ou tne dorsum, is covered with a flocculent 

 Avax secretion. The iusects are thickly congregated ou 

 the stems and overlaid with wax.

This species ^ollected ou (^iiUlaja saponaria Mol. was 

 seut to US by Prof. Carlos E. Porter from C'hile in March 

 1913. Only a few pupa cases were on the leaf and the wax 

 secretiüus on them were so broken that it is impossible 

 to tell what the original shape ofthe wax fringe was. 

 The cases have a lateral fringe of ñocculent filaraents 

 which we think must have extended on the leaf to half 

 the width of the case. The color of the case islight yellow 

 with a darker yellow mesón. 



Pupa case. — (Lám. LXX, fig. N) Size: length 2. 12 

 mm., width 1. 36 mm; color, light yellow, with the central 

 portion ofthe dorsum darkbrown. Margin(Lám. LXX, ñg. 

 P) entire, the sabmarginal área darker in color than the 

 rest of the pupa case and marked at defiuite iutervals with 

 darker horizontal lines. The width of the sub-margin is 

 0. 06 ram; the dorsum is silghtly convex, the abdominal 

 segments distinct. On the third, fourth and fifth abdomin- 

 al segment are groups of small circular pores, varying 

 in number from ten to five. On thé third and fourth seg- 

 ments an irregular light área is in the center ofthe group 

 of small pores. There are sevenpairs of simple, compound 

 pores, six pairs of which extend on the dorsum at the end 

 of the abdominal segments and around the orífice, and 

 one pair at the cephalic portion of the case. Between the 

 abdominal compound pores and the cephalic ones are two 

 light colored rounded áreas resembling pores. Yasiform 

 or'.fice (Lám. LXX. fig. O; subcordate; the cephalic raargin 

 straight; operculum sub-elliptical; the caudal margin con- 

 cave; Úngula long; extending 0. Ollmm below the can-
