The female, whicb in colour and depressed form resembles the 

 male, differs from that sex in having the interstices of the elytra 

 thickly and strongly punctate. As is the case in the other species 

 of this genus, the armature of the mandibles is subject to con- 

 siderable variation ; in small male specimens the subapical tooth 

 is entirely wanting. 



uEgus glaeer $ , Parry (var. minor?). 



M. angustus, rufo-piceus, nitidus ; capite antice vix emarginato, 

 depresso, parce subtiliterque punctulato ; mandibulis capite 

 paulo longioribus, arcuatis, apicibus acutis, intus ad basin 

 dente parvo armatis ; protborace transverse, lateribus cum 

 angulis posticis rotundatis, subtilissime punctato ; elytris 

 protborace triplo fere longioribus, leviter punctato-striatis, 

 interstitiis planis, lateribus dense punctatis, parce pilosis ; 

 pedibus rufo-castaneis ; tibiis anticis dilatatis, extus 3 vel 4- 

 denticulatis, quatuor posticis inermibus.'

One of the minor species of the genus, remarkable for its 

 smooth and polished appearance, and allied to yEgus myrmidon, 

 Thomson, from which species it differs, however, in its more 

 parallel and convex form, in the anterior part of the head being 

 scarcely emarginate, in the rounded sides of the prothorax, and 

 in the more delicate striation of its elytra.

 pone oculos emarginatis ; protborace capite latiori, rude 

 punctato, lateribus singulariter trilobatis ; elytris ovalibus, in
