376 Mr. 0. 0. Waterhouse on new 



base ; witli a strong tooth close to tlie base, a more prominent 

 one at one quarter from tlie base, a similar one at one third 

 from the apex, and a small one close to the apex. Between 

 the large teeth there are one or two small ones. The head 

 is transversely quadrate, with a slight rounded swelling close 

 to the anterior angle of tiic thorax ; the upper side is semi- 

 circularly impressed, slightly raised in front, with a deep 

 emargination, so as to form two somewhat acute teeth. The 

 head and thorax are both granulose, but the granulation at 

 the side of the head is much stronger than elsewhere. The 

 elytra are yellow, with the suture, the base, and the margins 

 narrowly bordered with black. The tibiee are pale reddish 

 yellow ; the anterior have a black line along the outer edge, 

 which has a few very small teeth ; the middle pair have an 

 acute spine at the middle; the posterior pair are unarmed. 

 The tarsi are reddish, marked with black. 



Long. Corp. 38-40, mandib. 17-20 mm. 



Hah. Usagara, German East Africa [Rev. A. N. Wood). 



The smaller specimen has two small teeth about the middle 

 of the leit mandible. The larger example has two small 

 teeth about the middle of the left; mandible and one i^imilarly 

 placed on the right mandible, and both mandibles have a 

 small tooth before the apical one. 



This species is closely allied to M. Savagei, which it 

 represents in E. Africa. It differs in the arrangement of the 

 colour and in the strongly deflexed mandibles.
