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 arcs 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 i)ore-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 iaterad of the groups of markings in 

 those regions to and including the first al)dominal 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 Iaterad and still another i)air just cephalad of the 

 anterior margin of the vasifoi'm orifice. Vasiform orifice sub- 

 ovate, surrounded by thickened integument and raised well above 

 the general level of the dorsum; operculum filling the opening.
