proportions distinguish it from K. panzeri. It is important to note 

 that the pronotum is black, or at least very dark, with the hiteral 

 margins pale and transparent. In the male the elytra and wings 

 are fully developed, but in the female the former are truncate and 

 the latter rudimentary. To obtain specimens perhaps the best 

 method is to sweep nettles, heather, low bushes, and the long grass 

 of rides in woods, to beat larger bushes and some trees, or to search 

 under moss and dried leaves. It often comes to sugar and occa- 

 sionally may be seen on the wing. It appears to he mature from 

 May till September, but perhaps is met with most frequently in 

 June and ^n\y. In Lapland it lives indoors and, according to 

 LinnjBus, consumes the dried fish of the inhabitants. K. lapjionicus 

 is common and widely distributed over central and northern Europe ; 

 but it is seldom found in the south, and then onl^^ at some eleva- 

 tion. In England it seems to be confined to the south and south- 

 east. It has been taken in several localities, in Surrey — Oxshott, 

 Albury, Gomshall, Horsley, Byfleet, Dorking, Haslemere, Devil's 

 Punch Bowl, Penslake, and Ockham Common. A few localities in 

 Sussex — Slindon, Wood Eartham, Dane Wood and Cocking — have 

 been reported. It is often taken in the New Forest, and is recorded 

 for Hants also in Pamber Forest and Parkhurst Forest in the Isle 

 of Wight. Sunning Hill (Berks), Epping Forest (Essex), Exeter 

 (vaults of City Bank), and Aldermaston (Devon) are all the remain- 

 ing records that have come to hand. 



Ectobius perspicillaris, Fuessly, is of about the same size as 

 the last species, but is of a general pale straw-colour. The pronotum 

 is of a reddish tinge ; the disc has a few dark dots, and the margins 

 are clear. In both sexes the elytra extend beyond the tip of the 

 abdomen. The insect has a more southern range than E. lap- 

 ponicus, being not very common in the northern part of Europe. 

 It is widely distributed in the centre and south, however, and 

 reaches to Algeria. There are very few certain records for Eng- 

 land : — Box-hill, Woking, Reigate, and Mickleham (Surrey); near 

 Tunbridge Wells and Faversham (Kent); Hastings, Slindon, Charl- 

 ton Forest, and Bognor (Sussex). Other localities that have been 

 mentioned are : — Devon, New Forest, Darenth Wood, and Birch 

 Wood (Stephens), Ruislip, Bournemouth, Lulworth Cove, Co. Down. 

 Luff says it is common in Guernsey and Alderney. 



Ectobius panzeri, Steph., is the smallest of British cockroaches, 

 the distance across the expanded wings being only 12mm. On the 

 pronotum are some scattered dark markings, which are arranged 

 somewhat in the form of two longitudinal lines. The elytra and 

 wings are fully developed in the male, but in the female they are 

 much abbreviated and quite useless as organs of flight. With us K. 

 panzeri is usually a somewhat dark insect, some specimens, how- 

 ever, being much darker than others, especially in the legs. 

 Stephens described this very dark form as a distinct species, under 

 the name of nigripes. The fact is, however, that the insect becomes
