General colour pale ochreous. Vertex ronnded, with 

 greyish stainings on the fore margin. Ocelli distinct 

 and dark brown. Eyes grey. Pronotum with a fuscous 

 stain on each side blotched with black. Scutellum 

 with two triangular black marks, and with the usual 

 mask-like dots. Elytra yellowish grey, with the 

 principal nervures white and black, so as to give the 

 membrane an angularly streaked or a chequered ap- 

 pearance. Abdomen with a brown band across each 

 segment. Legs pale ; the hind pair with a fine black 

 line on the outer edge of the femur, and the same on 

 the inner side of the tibia. Frons yellow, rounded, 

 and marked by two broad greyish stains. A black dot 

 appears between each of these stains and the eye. 



This appears to be a rare insect. My figure is from 

 Mr. Douglas's cabinet, who took it at Darenth in 

 October. 



Length of body, 0-23 inch, or 6*0 millimetres. 



Idiocerus viduatus, Edwards, pt. i. p. 118. 



This " fine and very distinct species " I have never 

 seen, and Mr. Edwards has seen it but once. It was 

 beaten from sallow [Salix) in Foxley Wood, Norfolk, 

 in September. It may be distinguished from other 

 Idiocen by its "red-brown colour, and by the breadth 

 and the obliquity of the pale band on the elytron."
