SERRIOORNIA. 133 



catalogue, but the number both of species and allied genera has been 

 liirijfly increased by Mr. Gorhaiu, who has worked out the specimens 

 collected by Mr. G. C. Champion in Central America ; the species are 

 known by the peculiar excision of the sides of the thorax before base in 

 the males ; the antennae in Silt's are feebly serrate, but in some of the 

 allied genera, such as Thinalmus, they are strongly flabellate and 

 almost plumose ; there are three European species belonging to the 

 genus, of which one occurs rarely in Britain. 



8. ruficollis, F. (rubricollis, Charp.). Black, with the mandibles, base 

 of first joint of antennae, thorax and abdomen red; head finely and rugosely 

 punctured, eyes moderately large, antennae long and rather stout, feebly 

 serrate ; thorax transverse, uneven, with cc arse irregular punctures on 

 middle of disc, with sides incised and dentate before base in the male, 

 simple in the female ; scutellum rather large, rounded behind ; elytra 

 about four times as long as thorax, clothed with greyish pubescence, 

 thickly and rugosely punctured, with traces of raised lines ; legs black 

 or fuscous, with more or less of tibiae usually yellowish. L. 5-0 mm. 



By sweeping, &c. ; rare, and usually confined to fenny and marshy localities ; 

 Epping Forest; Dagenham, Essex; Potter Heigham and Wroxham, Norfolk; 

 Homing Fen ; Hovetou ; Burwell Fen ; Whittlesea Mere ; Brandon (Suffolk). 



PODABRUS, Westwood. 



This genus contains about fifty species, which are confined to Europe, 

 Northern Asia, and North America ; they are distinguished from 

 Telephorus by having the head very strongly contracted behind eyes, 

 the tibial spurs obsolete, and the tarsal claws bifid ; there are six 

 European species, of which one is found in Britain ; it is locally abundant 

 on or about oak, fir, and other trees in early summer. 



P. alpinus, Payk. (lateralis, L.). A large and elongate species, 

 which may easily be known by the long head which is strongly con- 

 tracted behind the eyes, which are very prominent; colour variable, 

 being lighter or darker testaceous, with the vertex of head and the 

 under-side of the body black, or with the elytra entirely black ; the ven- 

 tral part of the thorax is often more or less dark ; head coarsely ami 

 rugosely punctured, antennae long, with second joint longer than third ; 

 thorax transverse, subrectangular, with the posterior angles more or less 

 distinctly toothed ; elytra broader than thorax, elongate, finely and 

 rugosely punctured, with traces of raised lines ; legs testaceous, more or 

 less black in different varieties. L. 10-12 mm.
