118 Mr. A. Murray on Coleoptera from Old Calahar, 



to the mentum, which Amara has ; it has its paraglossse soldered 

 to, or rather forming part of, the ligula, which is a character 

 that, according to Lacordaire, should remove it not only from 

 Amara, but from the Feronida. altogether, and carry it into the 

 Pseudoferonidce. The dilatation of the anterior tibise, however, 

 and the want of squamules under the tarsi, prevent us placing 

 it with them. But there is another character which it possesses 

 in common with a small group of the Feronidce (a group with 

 which, however, it has no other connexion), viz. the want of an 

 accessory sutural stria, — a thing which, except in these few in- 

 stances, does not occur among the Geodephaga. I have unfortu- 

 nately only received a female, or at all events an individual which 

 has not the anterior tarsi dilated ; so that the essential characters 

 founded on the dilatation of the tarsi of the male are unknown 

 to me. On the whole, however, from its facies and other affini- 

 ties, I would place it among the FeronidcB, in a position apart, 

 taut not far from the Amara.

Anchomenus, Bon. 



1. A. angulaticollis, mihi. 



Elongatus, angustatus, niger; thorace angulato antice postice 

 et lateribus, postice valde coarctato et exciso, ad basin vix 

 capite latiore ; elytris ovatis, marginatis, depressis, ad su- 

 turam parum elevatis, punctato-striatis, interstitiis sparsim 

 distincte punctatis; antennis fuscis, ad basin ferrugineis, 

 femoribus pallide testaceis, geniculis tibiis tarsisque piceis. 



Long. 5|^ lin., lat, 2 lin. 



Elongate, narrow, black. Head smooth, shining, and im- 

 punctate, with a well-marked elongate impression on each side 

 in front at the base of the antennse ; labrum large, quadrate ; 

 mandibles, maxillse, mentum, and palpi piceous. Antennse fus- 

 cous ; three basal joints shining ferruginous, slightly flattened, 

 rather thicker in the middle than at either extremity. Thorax 

 somewhat hexagonal, in front a little wider than the neck, at the 

 base scarcely wider; the anterior margin slightly emarginate; 

 anterior angles obtuse, slightly rounded ; the lateral margin with 

 its anterior half extending backwards and outwards nearly in a 

 straight line to about the middle, when it turns in, forming an 

 obtuse angle, the extremity of which is slightly rounded; it 

 then continues obliquely inwards, making a deep excision on the 

 posterior part of the thorax ; towards the base it bends in, be- 

 coming for a short space straight, and then turning slightly 

 outward, so that the posterior angles are rather sharper than
