Tetraleurodes herberti, new species 
Pupa-case :—Average size 0.92 mm. by 0.64 mm.; shape sub- 
elliptical, slightly more pointed at the caudal end; color shining 
black. The case is closely applied to the leaf. Dorsum keeled 
along the median line with the raised area somewhat wider in the 
cephalic and thoracic regions than in the abdominal region. The 
segments are distinct with suture lines well defined, particularly 
across the keeled area. Outlines of rudimentary legs on the 
ventral surface plainly visible through the case. In the cephalic 
region on both sides of the median line is a circular mark or 
depression which is bounded by two markings arranged as ares of 
concentric circles. Caudad of these markings and close to the 
median line on either side is another group of two subcircular, 
clearly defined markings or pore-like openings, one latero-caudad 
of the other. In the thoracic region is still another pair of tri- 
angularly arranged groups of three irregularly outlined depres- 
sions, a pair on each segment suture from the thoraco abdominal 
suture to the vasiform orifice. In the cephalic and thoracic region 
on either side of the median line is a row of about five small cir- 
cular pores which passes just laterad of the groups of markings in 
those regions to and including the first abdominal segment. Smaller 
circular pores are present just caudad of the abdominal depres- 
sions, one for each depression. A pair of similar pores are found 
just cephalo-laterad of the anterior margin of the vasiform orifice, 
another pair laterad and still another pair just cephalad of the 
anterior margin of the vasiform orifice. Vasiform orifice sub- 
ovate, surrounded by thickened integument and raised well above 
the general level of the dorsum; operculum filling the opening.
