26 STUDIES IN AUSTRALIAN ENTOMOLOGY. 



and but slightly perceptible, further towards apex along same 

 line ; the punctures of the marginal row finer and widely placed 

 behind the punctate part, becoming towards apex merely fine 

 points ; border narrow not reflexed. 



Length 19, breadth 6^ mm. 



Hah. — Cloncurry River, Queensland. Received from Mr. 

 Charles French, Government Entomologist, Melbourne.* 



This species is readily distinguished from M. cylindrica, Macl., 

 (the only other species known to me), by the black colour of the 

 legs, labrum and mandibles ; the prothorax too is longer and more 

 convex in the specimen before me than in the examples of M. 

 cylindrica I have. I may remark that there is nothing in 

 Count de Castlenau's description of the third known Australian 

 species, M. howitti, excepting its smaller size, to suggest its being a 

 difi'erent species from 31. cylindrica ; I do not think it will likely 

 prove more than at most a variety of that species. 



* Since the above was written Mr. French has received, and sent to me, 

 another specimen of 31. frenchi, as coming from the north-west of Australia 

 " between Roeburn and the Murchison River, about three hundred miles 

 inland."— T. G. S.
