nearly straight. Prothorax rather broad in centre ; hind 

 margin formed b\- a hair\-, raised rim. Mcso-thoracic 

 spiracles exposed, dark. Thorax ahnost uniform in 

 colour. ]]^ijig-cases about 7mm. long. Lt\i^'s of moderate 

 length, stout, rather widely separated at their insertion, 

 hair}', especially the tibia; ; distal joint of tarsi dark ; 

 length of fore-legs 12mm., mid- 14mm., hind- 19mm. 

 Abdomoi of a nearly uniform brown tint above, yel- 

 lowish-white below ; segments fairly equal, except 10, 

 which is very small ; hind margin of 9 }iot truncated 

 but sloping off gradually to 10 ; very short lateral 

 spines on segments 8 and 9 ; sharp, curved, mid-dorsal 

 spines pointing backwards on segments 4 to 8. Anal 

 appendages rather short, sharp-pointed, hairy ; upper 

 and lower acutely triangular, aboitt equal ; laterals 

 shorter and rounder. The n}'mph of L. qiiadriinacithxta 

 bears a strong resemblance to that of L. dcprcssa ; it 

 is, however, less hairy ; the legs are perhaps a little 

 more slender ; the mid-dorsal tubercles of the latter 

 species are replaced b}- spines, and there are some 

 differences in the head, especially in the direction of 

 the eyes. [From Surrey specimens.]

 In this apparcntl}' uncomfortable position now followed 

 a length}' rest, during which the legs were occasionally^
