LACHNOSTERNA GRAVIDA. 227 



parts of the mouth furnished with very long setae ; the very 

 deeply cleft labrum has on each side very long setae , the 

 base of the mentum in the middle has a large puncture 

 bearing two very long setae, and on the middle has two 

 shorter setae , the sides of the mentum are on a different 

 plane to the middle and are coarsely punctate, and bear 

 very long setae. The base of the front femur is entirely with- 

 out any prolongation. 



A single specimen was captured in May or June 1878 

 in the Highlands of Palembang. 



10. Lachno sterna gravida, n. sp. 



Robusta, piceo-rufa, capite thoraceque piceis, abdomine 

 dilutiore, nitida, dense punctata, pectore pubescente ; clypeo 

 in medio emarginato , utrinque rotundato , vertice carinato ; 

 prothoracis margine lateral! tenui integro , lateribus ad an- 

 gulos anteriores, parum explanatis. — Long. 27 , lat. 12i- — 

 13| m.m. 



Head densely and coarsely punctate, and consequently 

 but little shining , the vertex strongly carinate , behind the 

 carina densely and rather finely punctate. Thorax rather 

 large , broad , the base slightly sinuate on each side near 

 the hind angles so that these are very obscurely produced 

 backwards , but they are very obtuse , almost rounded , the 

 surface is densely punctate, the punctuation being especi- 

 ally dense on the front , towards each side there is a space 

 on which the punctuation is scanty or absent. Scutellum 

 with a patch of punctuation on each side. Elytra shining , 

 at the base rather closely , towards the apex more sparingly 

 punctured , with narrow indistinct costae , and with the su- 

 ture more broadly raised. Pygidium moderately close punc- 

 tured. Second joint of posterior tarsi not quite so Ion»" 

 as the basal one. 



This species is closely allied to the Javanese Melolontha 

 leucophthalma Wied., but it is more closely and finely punc-
