4. Alphus subsellatus, n. s. B.M. 



A. obscure cinereus, fusco subtessellato ; antennarum articulis

 strigatis ; scutello apice bituberculato ; pedibus cinereis fusco

A species closely allied to A. tuberosus, but differs in the an- 

 tennae having the joints at the end spotted with dark brown ; 

 the thorax having none of the raised ochraceous markings so 

 conspicuous in that species on the hind part. The scutellum 

 has two small tubercles at the end which are of a pale ochra- 

 ceous ; the base of the elytra has not the regular rows of black 

 points so conspicuous in A. tuberosus ; each of the lateral mar- 

 gins has a dark strongly marked blackish streak ; on the back 

 of the elytra there is a transverse saddle-like grey spaee, but not 

 raised as in the A. tuberosus
