genus because of its general resemblance to the preceding species. 

 La Ferte appears to lay but little stress vipon the shape of the 

 intercoxal plate ; whereas La Corclaire makes it of considerable 

 importance. These two species appear designed to unite 

 Formicomtts and Antliicus. The large intercoxal plate (at least 

 of Australis) placing them in the former genus of La Cordaire, 

 and the rather square shoulders bringing them into the Anlhicus 

 of La Ferte-Senectere. 



Sp. 14. F. senex. De La Ferte. 

 Totus nigro-fuscus, subtiliter punctatus, griseo-pilosus ; thorace 

 antice transversim globoso ; elytris pone humeros non- 

 nihil depressis.

 I have not seen this species in any collection, and simply 

 copy the description from La Ferte. The head is transverse ; and 

 head, thorax, and elytra ai'e all of a fuliginous black, the latter 

 apparently without any spots. It cannot therefore be mistaken 

 for the next species. 



Sp. 15. F. Mastersii. 

 Nigro-piceus, creberrime punctatus griseo-pilosus ; capite ro- 

 tundato ; thorace antice transversim globoso, postice con- 

 tracto ; elytris maculis duabus obliquis elongatis rufis pone 

 humeros, alteris duabus griseis pone medium minoribus ; 

 antennis et tibiis ferrugineis.

 This species evidently comes near the preceding. The an- 

 terior maculjB do not appear to be constant. The roundness of 

 the head as well as the size of the insect, and the maculae on the 

 elytra, readily distinguish it from F. senex. 



I have ventured to name this fine species after its discoverer.
