much produced between them, but not quite meeting the 

 raised margin of the metasternal process. The basal joint of 

 the hind tarsus is very long, longer than the three following 

 together. By this character the genus is well distinguished 

 from CalUcerus. In Callicerus the anterior tarsi are said to 

 be only four-jointed ; in Porocallus they appear to me to be 

 five-jointed, but I may possibly be mistaken, as I have only 

 one example at my disposal, and in it the feet have been 

 clogged with gum-tragacanth. 



Porocallus I'nsigm's, n. sp. 



Niger, capite, thorace cl3'trisque fusco-nigris, densissime punctatis, 

 opacis ; abdomine nitido, crebre punctato ; antennis, palpis pedi- 

 busque rufis. 



Long. 6 millim. 



Antennae elongate, rather stout, but little thicker exter- 

 nally, third joint longer than the second, little longer than 

 the fourth, longer than broad, terminal joint elongate, con- 

 siderably longer than the tenth. Head broad and short, 

 extremely densely punctate, quite dull. Thorax a little nar- 

 rower than the elytra, transverse, slightly narrowed behind, 

 extremely densely, moderately coarsely punctate, quite dull. 

 Elytra broad, longer than the thorax, dull, densely punctate, 

 the colour towards the hind margin brown, the punctuation 

 there rather coarser and less dense. Hind body with each 

 of the basal segments depressed at the base, and there densely 

 punctate, each behind more sparingly and finely punctured. 



Yuyama, May 11th, 1881; one specimen, probably a 

 female. 



Group Myemedoniina. 



Saphocallus, nov. gen. 



Tarsi anteriores 4-, intermedii et posteriorea 5-articulati. Palpi 

 maxillai'es triarticulati, articulo tertio sat gracili, apice truncate. 



Antennae elongate. Head narrow, with convex eyes. 

 Thorax quadrate. Middle coxae slightly separated, but 

 neither the metasternum nor the mesosternum is much pro- 

 duced between them, so that a great space in the longitudinal 

 direction exists between the margins of these two parts. 

 Legs elongate. The hind tarsi long, the basal joint elongate, 

 not twice as long as the second joint, this latter a little longer
