var. nigripes. — Steph. (Mandib., vi, p. 48) describes this as a 

 distinct species. Fischer queries it as synonymous with ericetorum, 

 Wesin., and Brunner v. Wattenwyl gives it as synonymous with 

 lapponicus, L. A short time since I sent a couple of specimens to 

 Herr Brunner v. Wattenwyl, who says, in reply, that they agree 

 entirely in form with ericetorum, Wesm.,but in colour are much darker 

 than any he has seen, and that this species, in common with other 

 Blattidte, tends to get darker in colour when occurring in more 

 northern localities, his specimens from Spain and Dalinatia having 

 straw-coloured elytra and pronotum. 



Nigripes is very much darker generally than Panzeri, but the pale 

 vertex is not lost and shows up more distinctly. The pronotum, even 

 in the darkest specimens, retains at least part of the central pale 

 streak. The legs are pitchy-black, with the pale apex of tibia and 

 base of tarsus plainly visible. 



Stephens gives the New Forest and Dorsetshire ; my specimens 

 are from Bournemouth ; and Mr. G. T. Porritt took it last year at 

 Lelant, in Cornwall. 



3. — Ectobia livida, Fab. 



Blatta livida, Fab., Ent. Syst., p. 10 ; (Ectobius) Fischer, Orth. Europ., 



p. 107, tab. vii, figs. 16—18. 

 Ectobia livida, Brunner, Prod, der Eur. Orth., p. 35. 

 Bl. pallida, Olivier, Enc. Meth., iv, p. 319. 

 Ect. pallidus, Steph., Mandib., vi, p. 48. 



Generally straw colour. Head and antennae rather darker. Eyes blackish. 

 Pronotum rufo-testaceous, with clear margins and a few dark dots. Elytra lanceo- 

 late, with a few dark dots, and reaching beyond the apex of the abdomen <J $ . 

 Legs pale. Abdomen ferruginous or fuscous. Cerci testaceous, with dark markings ; 

 in the larva with the tips blackish. Length, 9 — 13 mm. 



This cockroach I have taken in the New Forest under dead leaves 

 in September, and have specimens from Bournemouth and Kuislip, 

 the latter taken by Mr. McLachlan (August). Stephens gives Darenth 

 Wood and Birch Wood (lividus), and Devonshire and New Forest 

 {pallidus). Mr. Saunders takes it at Woking. 



Stephens (Mandib., vi, p. 48) describes pallidus as a distinct 

 species. I have examined what are believed to be his types in the 

 British Museum, and think them a rather dark form of livida, Fab. 



Reputed Species. 

 Ectobius pallens. — Stephens (Mandib., vi, p. 46) describes this 

 species from a single dried specimen, which had been " taketi near 

 London," and Fischer (Orth. Eur., p. 106) queries it as synonymous
