There are no central groups of dorsal tubular 

 spinnerets, but these organs form a conspicuous feature 

 along the margin ; there are usually eight of them on 

 each side of the median lobes, of which the first five 

 are equidistant and rather close together ; the rest are 

 more widely separated; all have projecting pores, 

 but the first and second are much more prominent 

 than the rest. Median lobes approximate, small ; 

 outer lateral margin irregularly dentate or notched ; 

 second pair shaped somewhat like the blade of an axe, 

 but the form varies; third pair obsolete. Plates spine- 

 like, four on each side the median lobes, become 

 longer and stouter towards the preceding segment, the 

 last being much the largest. There is a spine imme- 

 diately anterior to the second lobes, another near the 

 third plate, and two towards the last plate. 



Larva elongate ovate. Antenna of five joints, of 

 which the last is as long as the rest together. Formula, 

 5, 2, 1 (3, 4) ; the last joint has 3 4 long hairs. 



Habitat. A serious pest in many places, and most 

 difficult to keep in check. It has occurred on the 

 following plants in the Royal Botanic Gardens, Kew : 

 Licuala grandis, Dcemonoropx (C-iihmtnx} Lewisia/ims, 

 OhrysaMdoca/rpus lutescens, and more sparingly on 

 V<ni<l<nms conoideus. I have received it also from the
