COMMONLY CALLED BUGS. 157 



antennae pale reddish-yellow. The two first with large black 

 spots of unequal size, distributed irregularly throughout their* 

 entire length ; the first joint having also a broad black ring 

 before the apex. The fourth joint black, with the exception 

 of the apex, which is reddish-yellow. Head with two lon- 

 gitudinal channels. Thorax with a dorsal ridge. Eyes 

 small, black. Behind the eyes is a deep transverse channel, 

 beyond which are placed the ocelli of a clear, shining red 

 colour. Thorax in front with two somewhat rounded eleva- 

 tions ; the sides wrinkled ; the shoulder angles and dorsal 

 ridge, terminating in bhmted dentate processes. Scutellum 

 small, convex, triangular. Hemielytra flat, narrowing 

 gradually from the base until beyond the third pair of legs, 

 when they again widen out until they reach the termination 

 of the corium (or leathery portion) on the costal edge, at 

 which part they are widest. The ribs of the corium very 

 strong ; the cells somewhat opaline. Membrane rather iri- 

 descent. Thighs and tibia? spotted with black ; the former 

 with a broad black ring before the apex ; and the extreme 

 tip of the latter also black. The claws, basal and tip of the 

 anti-penultimate joints of the tarsi black. 



This genus is closely allied to 3fetacanthus, which it very 

 much resembles. 



The specimen from which I have made the description was 

 captured by T. V. WoUaston, Esq., some years ago at Pang- 

 bourne, Berkshire, and is unique.
