with surprising agility when disturbed. The 

 remainder of the species are more or less 

 rare. 



^PUS. 



The two species of this genus have the 

 curious habit of living under stones on the 

 sea-shore at, or even (it is said) below, low- 

 water mark, where they are only uncovered 

 during spring tides. They are both very 

 minute, and the principal points of difference 

 seem to be that ^ marinus has the posterior 

 angles of the the thorax right angles, whilst 

 RoMni has these angles slightly obtuse. 

 Both species measure about one line in 

 length and are of a yellowish colour and 

 very flat. 



PERILEPTUS. 



The single species of this genus, P a/reo- 

 latus, is about one line in length ; the head 

 and thorax are pitchy black, and the elytra 

 are reddish yellow with a darker side mar- 

 gin. Of its habits I know nothing ; the 

 species is given in Cox's Handbook as "not 

 common." 



HARPALIDiE. 



We now have to consider the'characters of 

 those genera the species of which have four 

 joints of the male anterior tarsi (and generally 

 also of the intermediate tarsi) dilated. The 

 genera, though only six in number, are by no 

 means easily tabulated ; indeed, for the 

 beginner, the only tabulation which is likely 

 to be of service is to divide the family into 

 two groups according to size, and then to 

 describe separately the genera which fall 

 into each group. 



A. Length, 4 lines or over. . genera Diachro- 

 musy Anisodactylus, and Ha/iyalus (part) . 



Diachromus — This genus contains a sin- 

 gle British species, D, Germanus, which is 

 very rare, which measures 4 lines in length, 

 and has the head yellowish, the thorax 

 green or blue, the elytra yellow with a blue- 

 black spot on the hinder half, and the legs 

 yellow. 



NATUEALIST. 



Anisodactylus. — This genus contains two 

 British representatives, viz., A Tnnotatus 

 and A pceeiloidss, both of which measure 

 slightly under half-an-inch in length. A. 

 bin^tatus is black, with two red spots between 

 the eyes — a character which distinguishes it 

 from all other British Carabidae. It occurs 

 pretty commonly on muddy shores. A. 

 poeciloides is green, with the posterior angles 

 of the thorax rounded. It may be distin- 

 guished from any Harpalus, which genus it 

 closely resembles in general appearance, by 

 its greater breadth, and by having the dila- 

 ted tarsal joints of the male covered beneath 

 with long hairs. The apical spine of the 

 anterior tibiae also is three -pointed. This 

 species is moderately common. 



B. Lenth, under 4 lines . .genera Dichiro- 

 trichus, Har^alus (part), Stenolophus^ 

 and Bradycellus. 



Dichirotrichus. — The two species of this 

 genus are easily distinguished from Stenolo- 

 phus and Bradycellus by their size (2^ to 3^ 

 lines) and by the whole body being thickly 

 punctured and hairy. Both species are of 

 a pale yellow-ochre colour with a dark 

 marking of an oblong form on each elytron, 

 but the commoner species, JD. pubescens, is 

 sometimes entirely pitchy brown. In D. ob- 

 soletuSf which is also the larger species, the 

 striae on the elytra are impunctate, although 

 the^interstices are thickly punctured ; where- 

 as in I), pubescens the interstices (and whole 

 upper side) are not so deeply punctured, but 

 the striae are distinctly punctate. Both 

 species are fairly common on sea-shores and 

 in muddy places on the banks of rivers, &c. 

 They may be distinguished from the genus 

 Barpalus, which they much resemble, by 

 the intermediate tarsi of the males not being 

 dilated, while they are distinctly so in 

 JIarpalus. 



Earpalus — This genus, the species of 

 which differ so much among themselves, 

 is easily distinguished from Stenolophus and 

 Bradycellus by the greater size of the spe-
