226 LACHNOSTERNA BARBATA. 



Sumatra do not differ iu any important respect from those 

 from Java. The meutum in this species is small, and is 

 very deeply impressed along the middle; the tooth of the 

 claws is very large, and curved, it is indeed even larger 

 than the apical portion of the claw , to which it is 

 similar in form. Rhizotrogus exactus Walk, from Ce3^1on 

 is I believe an allied species. A still more closely allied , 

 but distinct, species occurs in Borneo (Sarawak).

Sat elongata , posterius latior , supra opaca , pruinosa 

 nigricans , elytris sanguineo-nigris , pectore villoso , abdo- 

 mine pallido , anteunis rufis , pedibus piceo-rufis ; clypeo 

 anterius emarginato ; prothoracis margine laterali vix in- 

 terrupto ; elytris late sed obsolete costatis. — Long. 20 , 

 lat. 9 m.m. 



Antennae 10-jointed , 5th and 6th joints angulate in 

 front, 7th with a short prolongation, club quite small. 

 Head much narrower than the thorax , the surface coarsely 

 and closely punctate , clypeus moderately long , emarginate 

 in front in the middle, its margin but little reflexed. Tho- 

 rax rather narrower than the elytra , a good deal broa- 

 der in the middle than in front and behind , the hind an- 

 gles very obtuse, the surface moderately closely punctured 

 and quite dull, the punctures more scanty on the middle, 

 each puncture is sharp and well defined in front , but is 

 not so definitely limited but rather as it were slightly pro- 

 longed behind, so that at the sides where they are most 

 dense there is a slight strigose appearance; .the lateral 

 margin about the middle almost severed by three or 

 four setigerous punctures. Elytra somewhat sparingly and 

 not coarsely punctate , and with broad , impunctate , bat 

 scarcely elevated costae. Pygidium closely punctate. Ven- 

 tral segments finely and sparingly punctured. Spurs of 

 hind tibiae rather broad. 



This is an ordinary species in appearance, but has the
