 pronoto striis lateralibus integris ; elytris striis 1-3 integris, 

 sulurali ante medium abbreviata ; proin-gidio p3-gidioqiie sat

Ova], convex, black, and sliinin<]:; ; tlie liead, stria nearly 

 stiaif^'ht anteriorly, surface and also the mandibles ratiier 

 closely punctulate, behind the stria are two feeble impres- 

 sions ; the thorax is very feebly punctulate, with two lateral 

 striai, the external anteriorly passes the angle, internal is 

 crenulate behind the head and not interrupted ; the elytra, 

 stripe, there is no subhumeral, 1—3 dorsal are complete, the 

 first turns towards the second at the base, and the interstice 

 between the second and third widens out anteriorly; tlie 

 pygidia are somewhat closely punctate, and some of the 

 punctures are ocellate, esi)ecially on the outer parts ; the 

 mesosteriiuni is sinuous and markedly maroinatc, the marginal 

 stria laterally does not quite reach the nietasternal suture; 

 the anterior tibite are 5-dentate, the two apical teeth are close 

 together and have a common base. 



Tills is only the fourth species of Tlister recorded from 

 Madagascar; Ilisier goudod and cequlslrius, Mars., are now 

 assigned to Atholus.

 stiucture need not disturb my systematic arrangement of the 

 Histeridae in placing it in the section with emarginate or 

 sinuous mesosttrna.
