ANOMOOLOSSI'K. Chaiul. 



This geuus differs from Ch/aenius by the entire absence of any 

 mentum tooth, the emarginution being entirely tilled with the basal 

 membranous expansion of the ligula. The mandibles are also more 

 elongate and less arcuate. 



The males have the same pubescent space near the tip of the 

 middle tibiae which occurs in the more highly developed Chlacniita. 

 The abdomen is punctured and pubescent over the entire surface, 

 and the basal line of the elytra angulate at the humeri. The pro- 

 sternum is margined at tip and coarsely punctured in all the species, 

 and the metasternal episterna long. 



The last joint of the maxillary palpi is glabrous in emnnjinntiiti, 

 and slightly pubescent in the other two, the labrum deeply emarginate 

 \n pusillus, less in einarginatus, and very feebly in amocnus. 



In color they all very nearly agree, head and thorax green, more or 

 less bronzed, elytra bluish with brownish pubescence. Legs jcile. 



With these preliminary remarks, the following table will further 

 assist in recognizing our species. 



Thorax broader at base than apex, sides not at all sinuate posteriorly, hind 

 angles obtuse, labrum naoderately emarginate, last joint of maxillary 

 palpi glabrous eniai'giiiatiiN. 



Thorax with base and apex equal, sides very feebly sinuate posteriorly, hind 

 angles obtuse, labrum feebly emarginate, palpi slightly pubescent.
