 CURATOR OF THE GROSTENOB MUSEUM, CHESTER. 



ICEUTA EWARTI, 71. Sp. 



9 . Adult (fig. 1) after gestation, piceous, widely ovate, sometimes nearly 

 circular, very convex behind, narrowed and somewhat flat in front ; margin with a 



double row of short, 



stout, waxen, append- 

 ages, of which the 

 outer are much the 

 largest, and more 

 widely separated ; 

 dorsum completely 

 covered with the same 

 material, but without 

 design or distinct ar- 

 ticulations in any of 

 the specimens to 

 hand; body shrivelled 

 beneath, forming a 

 cavity in which the 

 eggs are laid, and, subsequently, the larvae are hatched. Antennae (fig. 2) shorter 

 than the legs, of ten joints : 1st much the widest, 2nd, 4th, 5th, 6th, 7th, 8th, and 

 9th shortest ; 10th as long as 2nd and 3rd together, and somewhat claviform ; there 

 are a few hairs on all the joints. Mentum very short, monomerous ; unexpanded 

 filaments about half the length of the leg. Legs short, ordinary, with many short 

 scattered hairs, most numerous on the inner margin of the tibiae ; claws rather blunt 

 and apparently retractile. Dermis above almost covered with large raised spinnerets, 

 which present, as they are focussed under the microscope, the various patterns 

 shown in the figures (3, 3a, 3b) ; usually these have four clear, central, circular 

 spaces, forming a quatrefoil (figs. 3a, 3b), but in a few instances there are one, 

 three, or five ; there are also a number of scattered hairs ; dermis beneath with 

 the spinnerets much smaller, but with the hairs more numerous and longer than 

 those above. 



? . Second stage : antennae of seven joints, tapering from 1 to 6 inclusive ; 

 7th claviform. This description is from an effete skin, of which there were many 

 examples attached to the midrib of the leaves. 



Larva of ? : antennae (fig. 4) slender, and, exclusive of hairs, nearly as long 

 as the body, of six joints, 2nd, 3rd, 4th and 5th, of equal length and width, 

 6th as long as the three latter together, has five long hairs, and one short. Eyes 

 very large (fig. 4), prominent, obconical. Anal segment with four exceedingly long 

 hairs, twice the length of the body. 



cf . Nothing but tl)e thorax (fig. 5) and part of an antenna was found ; the 

 structure of the latter was normal.
