or the base. The legs are yellow, only the bilobed fourth joint 

 and the claws and the claw-joint are infuscate. The elytra are 

 coriaceous, the scutellum and the suture concolorous. 



There is no species of Silis known to me with which this little 

 insect can be readily compared ; in size it is a little larger than 

 S.pcmxiUa Gorh. (Biol. C.-Am., Col. iii. pt. 2, p. 304), but the sides 

 of the thorax are quite different — tlie projecting tooth of the front 

 part of the margin and the acute hind angle leaving a " nick " 

 between them. The bright yellow legs and neatly margined elytra 

 are different from anything I can recall in this now extensive 

 genus. 



Upwards of fifty species are described in the Biol. C.-Am. from 

 Central America, several others are recorded from the United 

 States, and there are numerous undescribed species in South 

 America, besides many species from other parts of the world, 

 which will fall into allied genera — as Aclytia from New Zealand ; 

 Silidius Gorh., Africa. 



Eight examples were obtained.

In the section of Pelonium in which P. quadrisignatum Spin, and 

 P.crinitum Klug come, this insect is most like P. lineolatum Gorh., 

 from which it differs by the antennae being yellow at the base, the 

 legs wholly yellow, but is obviously variable in colour. When 

 specimens have been collected from intervening localities, it is 

 probable that several of the described species will be united as 

 varieties ; two specimens were obtained.
