HARPALUS. 



The species of this genus vary consider- 

 ably in size, but they are generally easily 

 recognised by their compact form and by 

 the intermediate tarsi of the males being 

 widely dilated — these joints not being fur- 

 nished with the long hairs which form a 

 sole to the feet of Dichirotrichus, Anisodac- 

 tylus, and Diaolironms. The arrangement I 

 have followed is nearly that given in Cox's 

 ••Manual," being, I believe, the simplest 

 manner of separating the species. They 

 are divisable at once into two groups, the 

 first comprising those which have the upper 

 side more or less thickly punctured and the 

 elytra pubescent ; the second those which 

 are destitute of regular punctuation (except 

 occasionally the outer interstices; and where 

 pubescence is wanting. 



Gr. I, — Interstices of the elytra punctured 

 and hairy (head and thorax generally punc- 

 tured) . 



1. Headi tJwrax, and elytra greenish or 

 Uuish : — 



Length i inch ; posterior angles of the 

 thorax rounded ; colour dull . . olscwus. 

 Length \ inch ; posterior angles of the 

 thorax rounded ; colour bright - azweus. 

 Length about 4 lines ; posterior angles 

 of the thorax right angles . .punctatnlus. 



2. Head and thorax pitcliy ; elytra dull 

 green : — 



Posterior angles of the thorax pointed ; 

 length ^ inch sahdicola- 



Posterior angles of the thorax rounded ; 

 length i mch ; sides of thorax much 



rounded « rottmdicoUis. 



3. Head, thorax, and elytra pitchy or hlach. 



a.~Length under 5 lines. 



Thorax nearly square and with the 



sides much rounded in front 



mpicola, puncticollis. 

 These species resemble one another very 

 closely, and are with difi&culty distinguish- 

 able from description. Rupicola is broader 

 and longer and has a duller appearance 

 than 2J'^t,ncticollis, which has a more shiny 

 appearance, and measures from 3 to 3^ lines. 

 Thorax much wider than long with 

 the sides rounded in front. Punctu- 

 ation not so distinct as in the two 

 previous species. Length 3^ lines . . 



rufibarbis (I'ujilabris ) . 

 Thorax with the sides not rounded in 

 front; length 2| to 3 lines -jijarallelus, 



h. — Length over 5 lines : — 



Head and thorax not punctured ; 



elytra with golden pubescence 



ruficornis. 



(Scybalicus oblongiusculus, a species re- 

 cently introduced as British, resembles H. 

 riificornis in appearance, but has the pos- 

 terior angles of the thorax rounded, whereas 

 ruficornis has these angles right angles ) 



Gr. II. — Upper side not punctured (ex- 

 cept the base of the thorax and the outer 

 interstices of the elytra occasionally). 



a. Thorax broader in front than behind. 



1 . Outer interstices of elytra punctured ; 

 elytra deeply sinuate before the apex ; 

 colour bronze, green, blue, or black. . 



pvoteus. 



2. Outer interstices not punctured ; 

 elytra not deeply sinuate behind. 

 Antennae and legs black or pitchy ; 



colour like proteus ignavus. 



Antennae and legs red ; colour more 

 or less pitchy consentaneus. 



All the above measure from 34 to 5 lines.
