PHYTOPHAGOUS COLEOPTERA FROM BURRUH 211 



of the posterior tarsi as long as the following three joints 

 together ; claws appendiculate. 



Bhamò, June 1885. 



M. gracilicornis may be separated from several other closely 

 allied species by the long and slender antennae which nearly 

 extend beyond the elytra , by the deep lateral depressions of 

 the thorax, the comparatively strong punctuation of the elytra 

 and the unicolorous pale tìavous colour ; M. polita has a much 

 more transverse thorax without the deep impression and the 

 elytral punctuation is finer. 



124, IVIimastra i>olila,5 n. sp. 



Black ; above pale llavous ; the terminal joints of the antennae 

 and the posterior tibiae fuscous ; thorax transverse with lateral 

 and basal depressions ; elytra very finely punctured, the extreme 

 apical margin piceous. 



Length 3 72 lines. 



Head impunctate, the frontal tubercles strongly raised, sub- 

 contiguous ; antennae two tliirds the length of the body, slender, 

 llavous, the six or seven terminal joints fuscous or black ; thorax 

 transverse, twice as broad as long, the sides nearly straight, 

 slightly narrowed at the base , tlie surface with a transverse 

 lateral and a central basal depression, impunctate, shining; elytra 

 narrowly elongate, very finely punctured, the interstices very 

 slightly rugulose near the suture, the extreme apical margin 

 piceous ; below (with the exception of the upper part of the 

 breast and the sides of the metasternum) black ; legs llavous, a 

 streack on the upper side of the femora, the intermediate and 

 posterior tibiiu and the tarsi, piceous. 



Tenasserim, Thagatà, April 1887. 



Very closely allied to M. ChenelU Baly but separated by the 

 much more transversely shaped tliorax, tlie shining and very 

 finely punctured elytra and tlieir scarcely rugose interstices.
