ulnar vein coaleecent with the posterior one ; discoidal area very broad, regularly 

 reticulated. The elytra, at about the junction of their outer and middle third, have 

 a crescentic whitish spot, with the concavity inwards. Wings smoky at the apex. 

 Posterior femora green above, reddish below ; knees fuscous ; posterior tibiae sangui- 

 neous, spines fuscous. Apex of the abdomen reddish in <J . Valves of the ovipositor 

 $ with an external tooth. Length, 15 — 25 mm. 



This insect is generally distributed all over Europe, and I have 

 specimens from several localities in the South-Bastern Counties of 

 England. It should be looked for about August in dry meadows, and 

 though local will, I expect, be found fairly plentiful. 



In the British Museum Collection I found sixteen specimens 

 labelled lineatus, Panz., but none of them were of this species, while 

 among the viridulus, L., were two genuine lineatus, Panz.

Colour green ; $ sometimes with fuscous, sometimes with rosy-red markings. 

 Vertex with a very short longitudinal central ridge at the apex ; antennae testaceous, 

 darker at apex, filiform, longer in $ than in $ ; palpi concolorous. Pronotum with 

 the lateral ridges angled very slightly near the anterior border, and approximating 

 there, somewhat thickened posteriorly, crossed from without inwards by a broad 

 black streak. The lateral ridges are usually pale, the median one green. Elytra 

 with the anterior part fuscous in the $ , of a rosy tint in ? ; posterior part green 

 in both sexes. Mediastinal area reaching beyond the middle of the elytra, narrow, 

 undilated at the base ; discoidal area with the reticulations sub-regular ; ulnar veins 

 diverging from the base. Wings in both sexes with the apical half more or less 

 smoky. Posterior femora generally green, sometimes deep rosy-purple, knees con- 

 colorous, posterior tibiae testaceous, sometimes rosy, spines fuscous at the tip. Valves 

 of the ovipositor without an external tooth. Length, 15 — 24 mm. 



This species also is widely distributed over Europe, and is found 

 in Siberia and Amur. I have specimens from all over England and 

 from Wales, and have taken it in Co. Dublin and Co. Limerick in 

 Ireland. It seems to be commonest on elevated grass lands ; this 

 year I have found it abundant on Dartmoor and in the neighbourhood. 



There is a form of the ? with the sides of the head and pronotum, all the legs 

 and the anterior part of the elytra, of a deep rosy colour. This may have been 

 Stephens' rubicunda, but his specimens in the British Museum Collection cannot, I
