12 COLEOPTERA OF NORTH AMERICA^ 



This tribe contains but one g'cnus Lorieera, in our fauna, with 

 whicli Elliptosoma Woll., a Maderaii form, has been associated. 

 This is said to differ in the absence of nietasternal epiniera in 

 the former and their presence in the latter, but in all the speci- 

 mens of Lorieera examined the sutures between the episterna 

 and epiniera are quite distinct. 



Associated for a time with the Fanagseides, Lorieera has been 

 removed by LeConte, followed by Schiodte, Schauin, and 

 Chaudoir. While it must be considered a member of the present 

 sub-family allied to the Elaphrini and Nebriini, it presents two 

 striking characters at variance with all the tribes of Carabina? 

 and which approach it to the Harpalinae, the deeply emarginate 

 anterior tibiae and the presence of the internal elytral plica which 

 is so well marked in Pterostichini and Panagteini. 



Tribe VII.— IVEBKIIIVI. 



Antennce with four basal glabrous joints, inserted under a slight 

 frontal plate which is not extended backward over the eyes in a 

 supra-orbital ridge. Eyes round, moderately or very prominent, 

 distant from the buccal opening beneath, less however in Leidus 

 and Notiojjhilm. Head horizontal (front deflexed in OjriMhius 

 and with two supra-orbital aetie), and with one supra-orbital seta. 

 Parts of mouth variable, mandibles always with setigerous punc- 

 ture. Thorax usually with a setigerous puncture at the side and 

 hind angle ; both are absent in Opisfhius, and the. posterior in 

 Leistus. Elytra margined at base except in Opislhius, sides 

 narrowly inflexed, margin entire. Prosternum horizontal and 

 prolonged behind the coxte, the cavities open behind ; lateral 

 suture of thorax beneath normally distant from the margin ex- 

 cept in Opidhius. Mesosternum carinate in front. Metasternal 

 epimera indistinct, posterior coxsb contiguous. Legs slender, 

 middle and posterior tibiae spinulose or ciliate externally. Tarsi 

 slender, ciliate beneath. 



In NotiophUus the anterior tibiog are very obliquely truncate, 

 the inner spur above the apex. In the other genera both spurs 

 are terminal but placed slightly ol)liquely to each other. 



The genera which occur in our fauna belonging to this tribe 

 are as follows :—
