 (Stephens, '111. Brit. Ent. Maud.,' VI, p. 45 (1835).) 

 It should be noted further that the folded elytra do 

 not cover the .scutellum. The " apical triangular 

 area' of the wings (an interesting feature of our 

 native cockroaches) is rather conspicuous. On the 

 anterior margin of the underside of the femora are 

 two spines. The supra-anal plate in both sexes is 

 narrow and transverse, and the sub-genital plate 

 of the male has no styles. The genus as at present 

 constituted contains some fourteen species. The type 

 of the genus is Ectobius lapponicus Linn.
