ii. — Thorax with side-mai-gins concolorous, base scarcely biarcuate, 

 hind angles more obtuse ; tibise pitchy-red ; sedeagns as in 

 fig. 3. Length, 65 — 7'5 mm scarab seoides, L. 



With regard to colour, in all three species there is a form which 

 has the elytra with a red humeral spot and the apex yellow. In 

 S. bipustulatum it is rare, and the coloration is generally obscure. 

 In 8. quadrimacidatum it is the only form I have seen. In 8. scara- 

 beeoides it is as common as a form with the humeral spot absent, or 

 nearly so. S. bipustulatum has the side-margins of the thorax narrowly 

 yellow or concolorous, and the elytra may be entirely black. In 

 England the three species appear to be ecpjally common, but I have 

 not seen sufficient material to work out their distribution. In set 

 specimens, fortunately, the tip of the cedeagus is often found pro- 

 jecting from the end of the hind body. The male is easily recognised 

 by its abruptly bent claws.

ANTHICUS BIFASCIATUS, Rossi : A SPECIES NEW TO BRITAIN. 

 BY J. C. F. AND H. F. FRTEK. 



We are pleased to be able to add the above-mentioned insect to 

 the list of British beetles. 



The species is abundantly distinct from all the other members of 

 the genus known to occur in Britain ; it is smaller than A. antherinus, 

 which it most nearly resembles, measuring from 2 - 5 to 3 mm. in length,
