142 Sjyecies of Pasi?nachtis 



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

 palida?. An approach to this is also visible in the genus Carenum ; 

 some of the species of which resemble Pasimachus depressusin the 

 form of the thorax. 



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

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

 palmatcd tibia? of Scarites and its allies ; in some minor points, this 

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

 phous Harpalicla 1 , while the genus Gnathoxys, (Westwood,) uni- 

 ting to the oral organs of the Feronida?, the antenna?, 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 pygma?us (Dej.) of which, however, I do not 

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

 gies connecting the Brachinida*, and Harpalida?, the Scaritida? also 

 tending towards the same point ; in the form of the antenna? and 

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

 oral organs approximate it to Morio.
