 existed. As we have uever seen a specimen of M. puncti/rona, it is out of our power 

 to make a minute comparative diagnosis.

M. pilosi s, n. sp. — M. Bavus, capite rubro; segmento cephalico antice emarginato, profunde punctate, a 

 front e ordinatim angustato ; capite maudibulis pedibus acutiaque pilosis ; mandibulis distiucte tridenta- 

 lis; pedum paribus proxime ! 



Tlie coloration of this species is almost identical with M. rubriceps. The puncta- 

 tions on the cephalic segment resemble those on M. punctifrons. The cephalic seg- 

 ment narrows more gradually from the front, with its anterior angles more rounded 

 and the emargination deeper than in .1/. rubriceps. The number of feet given ahove 

 is unfortunately only approximate, as the alcohol having dried oil' the specimen, it is 

 in a condition hardly lit to describe from.
