142 Species of Pasimachus 



wards Mono, Catadromus, and the other allied genera of the Har- 

 palidic. An approach to this is also visible in the genus Carcnum ; 

 some of the species of which resemble Pasimachus deprcssusin tho 

 form of the thorax. 



Another link in this chain will be found in the genus Euryde- 

 rus, which with the head and body of a Harpalide, combines the 

 palmated tibias of Scarites and its allies ; in some minor points, this 

 genus exhibits a relation to Daptus, and the other androgynomor- 

 phous Harpalidae, while the genus Gnathoxys, (Westwood,) uni- 

 ting to the oral organs of the Feronidae, tho antennae, feet, and 

 pedunculated abdomen of Scarites, affords still another point in 

 the chain of affinitus. 



The last insect described in this paper, (which is probably con- 

 generic with Helluo pygmaeus (Dej.) of which, however, I do not 

 possess a specimen,) I regard as forming one of tho line of analo- 

 gies connecting the Brachinidae, and Harpalidee, the Scaritidae also 

 tending towards the same point ; in the form of the antennae and 

 body, it closely resembles some of the species of Ozmna, while its 

 oral organs approximate it to Morio.
