DESCRIPTION OF A NEW GENUS AND SPECIES OF SYDBOPniLID^ 

 FEOM NEW ZEALAND, and of a NEW SPECIES OF PHILHYDRUS 

 FEOM GREAT BRITAIN. 



BY D. SHARP, M.B. 



Ctloma,* nov. gen. Hydropliilidarum. 

 Corpus ovatum, convexum ; protliorace antrorsum aiifjusfaio. 

 Antenncv S-articulatce. 

 Palpi inaxillares articulo 2" incrassato. 

 Tarsi posteriores articulo primo qiiam 2" hreviore. 



Of the general form and appearance of a small Cyclonotiim, hut differing from 

 that genus by the short basal joint of the hind tarsus. Maxillary palpi formed as 

 in Cerei/on. Antennse 8-jointed ; 1st joint elongate and slender, 2nd about as stout 

 as first, but less than half as long, 3rd thinner than 2nd, and not quite so long, 4th 

 joint small, scarcely broader than 3rd, about as long as broad, 5th joint yery short 

 and transverse, intermediate in width between the 4th and 6tli ; joints 6 — 8 form an 

 elongate club. Hind tarsi short, about half as long as the tibiaj, basal joint shorter 

 than 2nd, 3rd also shorter than 2ud, about as long as the 1st, 4th shorter than 3rd' 

 5th joint rather longer than 2nd. Claws small. Mesosternum visible between the 

 middle legs as a small quadrangular or diamond-shaped plate, the front angle of 

 which is prominent, and forms the lower part of a perpendicidar carina. 



Tte insect for which this genius is founded is of considerable in- 

 terest, as it completes the connection between the Sphoeridiini {Geo- 

 pliilides, Muls.) and the HydropMlini. Though certainly belonging 

 to the Sphceridiini, it possesses the short basal joint of the hind tarsus 

 characteristic of the Hydropliilini. Its place is at the commencement 

 of the SphcEridiini.
