380 . BRITISH OEIBATIDiE. 



stigmata lateral, almost hidden by the advancing edge 

 of the abdomen. Pseiido-stigmatic organs with very 

 short peduncles and extremely large, flat, Indian or 

 Japanese fan-shaped heads, the distal edge of which 

 has a median, or nearly median, indentation or curving 

 in. The whole of the flat expansion is strewn with 

 extremely fine hairs or points. In consequence of 

 the singular form of these organs they may often be 

 observed to be blown about a little by the wind. 

 Second tectopedia well developed, the others small. 

 The appearance of the apodemata and sternum will be 

 best understood from the p)late (fig. 7). 



Legs of moderate length. The two hind coxEe large 

 and globose. Femora, especially the two anterior 

 pairs, with thin peduncles and greatly enlarged distal 

 ends. Genuals very small. Tibiae almost wine-glass- 

 shaped. Tarsi short but thick at the proximal ends, 

 inversely pyriform. Claws tridactyle, very heterodac- 

 tyle. Tactile hairs on first pair of legs long. There 

 are one or two short, rather spatulate hairs on most 

 joints of the legs, particularly the anterior pairs. Tarsi 

 with the usual fine hairs, and there are a few on the 

 other joints. 



Abdomen pointed both anteriorly and posteriorly ; 

 anteriorly it projects over the cephalo thorax and 

 becomes narrow, so that the progaster is gable-shaped ; 

 the sides of the remainder of the abdomen are strongly 

 curved. There is a close row of short, curved, spatu- 

 late hairs round the margin, and two longitudinal rows 

 of three or four similar hairs near the median line. 



Ny^nph. 



The nymph of this species so closely resembles the 

 adult that I do not think anyone would mistake it ; I 

 therefore have not figured it, and here only give the 

 diff'erences from the perfect creature (beyond the ordi- 

 nary fact of the nymph being monodactyle instead of 

 tridactyle).
