228 LACHNOSTERNA DISCEDENS. 



£ate, aud the sides of the thorax are less explanate at the 

 frout angles. 



Two specimens were captured in January 1878 at Soerian. 



11. La chno sterna convexa^ n. sp, 



Elongata, fere angustula, subparallela , transversim 

 valde couvexa, dense punctata, subnitida, pectore breviter 

 hirsute ; clypeo in medio fortiter emarginato , utrinque sub- 

 rotundato , vertice cariuato ; elytris fere ecostatis. — Long. 

 19 , lat. 9 m.m. 



Head closely punctate, the vertex strongly carinate, be- 

 hind the carina almost impuuctate, clypeus rather broadly , 

 and somewhat deeply emarginate in the middle , the lobes 

 on each side of the emargination nearly but not quite roun- 

 ded. Thorax broad, dilated at the sides in the middle, 

 the base scarcely sinuate on each side, the hind angles 

 rounded, the lateral margin scarcely distinctly crenulate, 

 and not distinctly explanate in front, the anterior margin 

 truncate , the surface very densely , evenly , and not coar- 

 sely punctured. Scutellum punctate. Elytra closely punc- 

 tate, the punctuation not so dense towards the apex as at 

 the base , appearing almost without costae , but the lateral 

 one distinct, the sutural one, broad, but little elevated, 

 punctate and so indistinct. Ventral segments somewhat 

 coarsely punctate ; breast with short pubescence ; base of 

 anterior femora with short, free angular prominence; hind 

 tibiae coarsely punctate externally; 2nd joint of hind tarsi 

 as long as the preceding one. 



This species appears intermediate between Melolontha leu- 

 cophthalma Wied. and Ancylomjcha bidentata Burm. 



A single specimen , captured in April 1878 at Soeroe- 

 langoen, has been brought home by the Expedition. 



12. Lachnosterna discedens ^ n. sp. 

 Crassiuscula, parum elongata, convexa, nigro-picea,
