42 BRITISH ClCADiE. 



several dark dashes. The former sometimes projects 

 over the latter like a hood or scale. Elytra pale brown, 

 rather longer than the abdomen, and marked by fine 

 nervures set with bulbose setae. Abdomen ridged with 

 yellow edges to the segments. End of pygofer yellow 

 and semi-arcuate. Legs fuscous, with dark claws. 

 The wings are obsolete. 



Macropterous male. Colour very similar to the 

 female. The elytra and the wings are fully developed, 

 and rather longer than the abdomen. The pygofer 

 seen in profile is square, with a small projecting anal 

 tube and pointed genital styles. The costa and the 

 apical borders of the elytra are very stout, and trans- 

 versely striated, as if ringed. In a less degree this 

 thickening is to be seen in the wings also. The frons 

 is dark between the keels, which are obvious, and not 

 forked at the vertex. Legs stout, with rather short 

 tarsi. 



A single Macropterous male was taken by the author 

 in Eomney Marsh in June, and a female afterwards on 

 the banks of a stream near Chichester. The male has not 

 been described before. It has its wings fully developed. 



This insect may be compared with L. adela, which 

 it rather resembles.
