retaining tlie genus apart from Anisodactylus, and the species will 

 find a suitable position between the amaroidex and serkexis groups 

 of that genus. 



Amphasia. — Here the characters are essentially those of Aniso- 

 dacti/Ins serlceus. The paraglossse are similar in form to Anisodactylus 

 and merely a little longer. 



Anisotarsus.— The sexual characters and those derived from the 

 posterior tarsi are precisely those of Am'sodacfi/his coenus and Isetus. 

 The paraglossse are a little broader than in typical Anisodncfi/li. 



Spon(Sopus.— The ligula and paraglosste are intermediate in structure 

 between the typical Anisodactt/lus and Xeslu7iofus, and the ligula is free 

 for a greater distance at tip. The sexual characters are those of the 

 amaroides group. The posterior tarsi are however slender. The elytra 

 being punctulate and with a single dorsal puncture this species forms an 

 intermediate between the discoideus group and serlceus. 



From the above remarks it must be evident that my opinion is that 

 the above genera are inseparable from Anisodncti/lus. I have examined 

 the species from every possible standpoint and 4can find no reason either 

 from my own studies or the remarks of others to do otherwise than 

 su"":ested above. 



While I have given these genera all the study possible with me 

 at present, I consider the question of the total suppression of Aniao- 

 ttirsus and Spoiujopns still open for further discussion, there is no 

 doubt in my mind, however, regarding Gi/niindrumorphus, Xestonotnn 

 and Amphasia. 



It is worthy of note in Anisi.dartijlus that we may have more than 

 one setigerous puncture at each angle of the clypeus while in most 

 Carabidoe there is but one and even this may be lost. 



Sub-Family FSE ID OM ORFHINjE. 



>liddle coxal cavities enclosed by the central pieces of the mi^so- 

 aiid metasternum. Head without supra-orbital setfe and with grooves 

 beneath of variable extent for the reception of the antenna. Eyes in 

 great part superior, very widely separated beneath from the mouth. 

 Legs short, contractile, tarsi slender, rigid. 



The genera which compose the present division are the most abnormal 

 of all Carabidce. That they belong to the family and should not be 

 separated is I believe now generally admitted, the only difficulty being 

 their proper position in the series, and from my own study they do 

 not seem to be well placed anywhere and are equally aberrant in any
