PHYTOPHAGOUS COLEOPTERA FROM BURMA 871 



stices flat, impunctate , slightly costate at the sides near the 

 apex , the 9."^ row uninterrupted ; underside and legs fulvous , 

 clothed with yellow pubescence, tarsi black. 



Palon (Pegu). A single specimen. 



The produced anterior portion of the head and the strongly 

 developed mandibles distinguishes this species from any other 

 Eastern form with which I am acquainted. 



3. Lema dimid-iatipenixis , n. sjd. 



Fulvous, the labrum black, the thorax not broader than long, 

 punciured at the middle ; elytra very strongly punctate -striate, 

 the base slightly convex, the anterior half fulvous, the posterior 

 one black. 



Length 3 Yg lines. 



Head impunctate, the space between the eyes triangularly 

 raised, the lateral grooves deep, the eyes triangularly notched, 

 the labrum black ; antennae slender, entirely filiform, the second 

 to the fifth joints gradually lengthened; thorax scarcely longer 

 than broad deeply constricted at the sides , this constriction 

 bounded above by a distinct ridge , the basal sulcation deep , 

 the surface with a few minute punctures on the disc and ante- 

 riorly, fulvous ; scutellum fulvous ; elytra with a slight but 

 distinct depression below the base, deeply punctured anteriorly, 

 the punctuation diminishing gradually in depth towards the 

 apex at which place the interstices are slightly convex , the 

 anterior half fulvous, the posterior one black, the anterior mar- 

 gin of this colour convex (in one specimen the posterior half 

 is dark violaceous), underside and legs fulvous. 



Palon (Pegu) August, September. 



This species was formerly considered by me as a variety of 

 L. stevensi (Ann. Mus. Civ. Genoa, 1889, p. 152) but several 

 other specimens being contained in this collection proving the 

 constancy in structural details and coloration I must look upon 

 them as specific characters. L. dimidiatipennis resembles some- 

 what L. papuana, Lac. but independent of the quite different
