LACHNOSTERNA MARMORATA. ii29 



elytris dilutioribus , nitida , pectore liaud villoso , subtilius 

 squamoso; capite brevi, clypeo in medio emargiuato , vertice 

 cariuato ; elytris nitidis , fortiter puuctatis , sat distincto cos- 

 tatis; prosterni processu post-coxali libero erecto , apice sub- 

 etnarginato. — Long. 20, lat. 10 m.m. 



Antennae 10-jointed, the club appearing 5-jointed in 

 consequence of' the 6th and 7th joints being provided with 

 prolongations as long as the leaves of the club , the 5th 

 joint also with an angulor projection from the front. Si- 

 des of the mentum much raised , bearing elongate , erect 

 setae. Head short, and broad, the vertex strongly cari- 

 nate, the clypeus a good deal emargiuate in the middle in 

 front , the surface coarsely and closely punctate. Thorax 

 broad , front angles obtuse , hind angles very obtuse , la- 

 teral margin fine , crenulate , surface rather coarsely some- 

 what sparingly punctured , the punctures rather irregularly 

 distributed. Scutellum punctate. Elytra rather coarsely 

 punctate , the punctures so formed and placed that when 

 magnified they give rise to an obscurely appearance of the 

 surface being transversely rugose , the costae rather narrow 

 and somewhat indistinct, the sutural costa broad and very 

 little elevated , punctured. Pygidium broad , coarsely punc- 

 tate. Breast furnished at the sides with depressed scales, 

 instead of hairs. Anterior femora with very short free an- 

 gular prominence behind. 



I have preferred in the present condition of the genus 

 Lachnosterna , to place this insect therein , rather than to 

 give it a distinct generic name; the structure of the an- 

 tennae and of the prosternal process will allow it to be 

 identified with ease. 



One specimen in March 1877 at Agam, several ones (7) 

 in January 1878 at Padang, and one in May 1878 in the 

 district of Rawas.
