AMERICAN COLEOPTERA. 171 



It is a singular character that the set^e which are found in the vast 

 majority of Carabidae, arising either from the middle of the side of the 

 clypeus or from its anterior angle, should be here (I speak especially 

 of P. cyanipes Kby.), functionally replaced by the lateral setae of the 

 labrum, which, instead of being directed to the front in the usual 

 manner, arise vertically and are long. The rather wide separation of 

 the posterior coxas does not appear to have been noticed. The temporal 

 cicatrix to which Putzeys directs attention (Stett. Zeitsch. 1868, p. 306), 

 is observed in Felecium as well as in Broscini. 



Tribe XLV. -Chlaeniini. 



Anteniife slender, rarely slightly compressed {Evoknes^ arising under a slight 

 frontal ridge, the three basal joints glabrous. Head not narrowed behind the eyes 

 to a neck, one supra-orbital setigerous puncture. Clypeus more or less prolonged 

 between the mandibles, often without the lateral seta. Eyes oval, moderately 

 prominent, more truncate behind in the Oodes. Labrum transverse, truncate 

 or emarginate, with three, four or six setse in front. Mandibles feebly arcuate, 

 without setigerous puncture externally. Maxillre slender, hooked at tip, ciliate 

 or spinous within, the outer lobe usually slender, biarticulate (except Callistufi), 

 the palpi moderately long, the terminal joint variable in form. Mentum broad, 

 usually emarginate ai^d toothed, sometimes feebly bisinuate in front (Evoleyies) 

 or even almost truncate (Brachylobusi, the basal suture always distinct, ligula 

 moderately prominent, usually free at tip and bisetose, the paraglossse membranous 

 more or less free at tip, longer or not than the ligula, elongate and slender in 

 AnomoglosKus and ciliate within, palpi moderate in length, the terminal joint 

 variable, the penultimate bi- or plurisetose or even without setse. Thorax variable 

 in form, the setfe of the margin either slender or entirely wanting. Body not 

 pedunculate, scutelhim distinct. Elytra margined at base, sides narrowly intiexed, 

 margin interrupted posteriorly and with a distinct internal plica, surface striate, 

 without dorsal punctures. Prosteruum prominent at tip but not prolonged. Meso- 

 sternum rather widely separating the coxre, grooved in front, the epimera narrow. 

 Metasternal epimera distinct, posterior coxse contiguous. Legs moderate, middle 

 and posterior tibise finely spinulose externally, the anterior moderately broad, 

 a few stout spines at the outer apical angle,, within deeply emarginate the inner 

 spur at the angle of the emargination. Tarsi slender, claws simple. 



The males have three or four joints of the anterior tarsi dilated and densely 

 spongy beneath. 



After the very able papers by Baron Chaudoir on this tribe (Bull. 

 Mosc. 1856 and 1857 ; Ann. Mus. Civ. di Genova viii, 1876', it seems 

 entirely unnecessary to enter into any further discussion of the subject. 

 I can not realize the necessity for separating CaUistus as a distinct tribe 

 but his conclusion concerning Atranus seems to me just. CaUistus affords 

 one of the rare instances in Carabidae in which the outer maxillary lobe 

 is formed of one piece by the complete fusion of the two which usually 

 exist, without leaving any trace of suture as is the case in Ameriztis. 

 The mentum of BracJiylohus (117), is the most complete illustration of
