304 Mr. D. Sharp's revision of the 



The species of this group prove clearly that De Saulcy 

 is correct in considering that the side-piece marked off 

 by the curved plica of the 1st dorsal plate is really the 

 homologue of the lateral margin ; in B. spinicollis and 

 B. longicornis this line is very close to the outside, and 

 thus marks off a lateral margin, which is slightly raised ; 

 in B. angustus the line is further from the side, and 

 makes the transition to the more ordinary species of the 

 genus, in which a side-margin appears to be entirely 

 wanting. 



Batrisus spinicollis, n. s. 



Eufescens, elytris sanguineis, longius pubescens, minus 

 subtiliter punctatus ; antennis elongatis, articulo singulo 

 latitudine longiore ; prothorace ad basin fortiter angus- 

 tato, insequali, disco profunde canaliculato, angulis ele- 

 vatis quatuor armatis, lateribus impressis, medio lateris 

 angulo prominulo ; elytris minus elongatis, minus sub- 

 tiliter punctatis, humeris parum angustatis, angulo 

 prominulo minuto, striola discoidali brevi, obscura, basi 

 quadrifoveolato ; abdomine minus subtiliter punctulato, 

 segmento secundo dorsali minus brevi, segmento basali 

 parum elongato, secundo baud duplo longiore, plicula 

 laterali a margine parum remota. Long. 2f mm. 



The unique individual of this very distinct species is 

 apparently a female ; the forehead is depressed in the 

 middle, the clypeus simple, the vertex carinate in the 

 middle, but not at the sides, and the legs are quite 

 unarmed.

Batrisus longicornis, n. s. 



Angustus, convexus, rufus, longius pubescens, antennis 

 pedibusque elongatis, gracilibus ; prothorace ad basin 

 fortiter angustato, ingequali, opaco, disco profunde cana- 

 liculato, utrinque carinula elongata posterius angulatim 

 elevata, ad latera impresso ; elytris parce baud fortiter 

 punctatis, stria suturali subtili, discoidali fere nulla ; 

 abdomine minus subtiliter punctulato, segmento secundo 

 dorsali minus brevi, segmento basali parum elongato, 

 secundo vix duplo longiore, plicula laterali ad marginem 

 approximata. Long. 2 mm.
