Fauvel, Ann. Mus. Genov. XII, p. 255 (1878). 



General characters of Philonthus. Maxillary palpi very 

 slender, the 4th joint acicular, much longer than the 3rd. Labial 

 palpi also slender, the 2nd joint ciliate internally, the 3rd fusi- 

 form. Head connected with the pro thorax by a slender neck. 

 Eyes not prominent, scarcely lateral. Antennae elongate^ rather 

 slender. Prothorax with a lateral line joined before the anterior 

 angles. Presternum px'oduced above. Metasternum rounded an- 

 teriorly, not produced. Legs slender ; tibiae spined ; anterior 

 tarsi dilated in the ^ ; posterior tarsi elongate, the 1st joint 

 equal to the 5th, joints 2-4 gradually shorter. 



Allied to Philonthus, but easily separated by the form of the 

 palpi and prosternum, and by having the transverse impression on 

 the neck, which borders the head, interrupted in the middle. 



A single species is known from New Guinea and an allied form 

 from Australia is here added. 



141. Mysolius chalcopterus, sp. n. 



Robust, black, shining ; antennae with the last three joints 

 white ; elyti-a bright coppery, sometimes with a tinge of purplish, 

 densely clothed with golden pubescence ; abdomen black, tinged 

 with purplish ; legs reddish testaceous. 



Head rather broad, sub-quadrate, strongly convex, narrowed 

 behind the eyes, with four or live irregular impressions in front, a 

 row of moderately strong punctures on the inner orbital margin 

 of each eye, and another row extending obliquely from behind the 

 eye to the middle of the posterior margin, strongly and rather 

 closely punctured about the posterior angles, which are rounded. 

 Antennae with the first four joints reddish testaceous, 5-8 fuscous, 

 the last three white ; the basal joint elongate, the 2nd short, 3rd
