There is certainly no reason why Perigona, should be placed as a 

 Truncatipenne. The two supra-orbital setae remove it from association 

 with the Harpalide series. Taking its entire organization it seems better 

 placed in the present tribe than anywhere else. 



Tribe XXVII.— Anchbnoderini. 

 Head oval or rounded, not prolonged nor constricted to a narrow neck; with 

 two supra-orbital setigerous punctures. Antennse slender, not thicker externally. 

 Eyes variable in prominence but always close to the buccal fissure beneath. 

 Thorax more or less cordiform the lateral margin distinct, setigerous punctures at 

 side striated the one in front of middle the second at the hind angle (except in 

 Lachnophorus where it is slightly in front). Elytra feebly margined at base, the 

 lateral margin distinct, apices rounded. Scutellum and scutellar stria distinct. 

 Tarsi slender, fourth joint simple. Claws simple. Posterior coxae contiguous. 

 Body above pubescent or pilose. 



In the above characters will be found all that will define the genera 

 placed here. With other genera the tribe might possibly be more 

 properly divided in three but for the present they will be considered 

 groups forming an osculant tribe. 



These groups are as follows : 



Antennse with four glabrous joints. 



Thorax ovate, lateral margin obtuse, the posterior setigerous puncture in front 



of the basal angle. Body subpedunculate Lachnophori. 



Last joint of palpi ovoid, suddenly acuminate at tip, the surface pubescent. 



Elytra with three dorsal punctures Liacliuoplioriis^ 



Last joint of palpi conical, gradually narrowed to tip, the surface glabrous. 



Elytra without dorsal punctures Euphorticus. 



Thorax cordiform, lateral margin acute, the posterior setigerous puncture at the 



hind angle. Body not pedunculate Anciionoderi. 



Last joint of palpi gradually narrowed to tip and slightly oval. Elytra with 



three feeble dorsal punctures Ancliouoderiis. 



Antennse with three basal joints glabrous. Thorax cordate margin acute, the 



hind angle with Setigerous puncture Atrani. 



Palpi as in Anchonoderus. Dorsal punctures not evident Atranus. 



The structure of the antennae of the first two tribes seems to have 

 been overlooked. The joints 2—4 are not absolutely glabrous in the 

 strict acceptation of the term but they are devoid of the fine punctuation 

 and pubescence which covers the following joints. 



From the characters above given it will be evident that the Lachno- 

 phori osculate closely with the Egini and the Atrani with the Platynini. 

 while the Anchonoderi are intermediate between the other two groups. 



Group Lachnophori. 

 Eyes large moderately prominent. Head oval, sometimes slightly 

 constricted behind the eyes, front more or less deflexed. Elytra not 

 margined at base, the apex with very feeble sinuation in Lachnophorus
