206 THERMONOTUS NIGRIPENNIS. 



between the lateral spines is raised , coarsely and conflu- 

 ently punctured , but with a smooth space and a minute 

 notch opposite the scutellum. The scutellum is rounded at 

 the tip. 



The elytra are slightly narrowing towards the end, their 

 shoulders and apices rounded ; between the scutellum and 

 the shoulders the base projects forward so as to form a 

 hump on each side of the scutellum. The elytra are strongly 

 but not densely punctured, but the punctures become smaller 

 towards the suture and apex; the sutural interstice is 

 strongly raised towards the end of the elytra , and the 

 two costae are tolerably well visible. 



Under surface and legs impunctate. The apical ventral 

 segment truncate posteriorly. 



Hah. Brunei (Borneo). — A single male specimen in 

 the collection of Mr. Rene Oberthür. 



Thermonotus Oberthüri, n. sp. cf. 



Length from the antennary tubers to the apex of the elytra 

 18, 5 mm., breadth at the shoulders 7 mm., width of the 

 thorax from point to point of the lateral spines 6,5 mm. 



Reddish fulvous, with the elytra slightly more yel- 

 lowish fulvous; the apical half of the mandibles, the 

 eyes and antennae , the legs (with the exception of the 

 coxae) and the apical third of the elytra black, the 

 latter with a faint blue tinge, but the line of demarka- 

 tion between the two colours not sharply defined. The 

 fulvous portions of the upper side are covered with a thin 

 and glittering ochraceous pile, on the black portions the 

 pubescence is black; on the undersurface of the base of 

 the 3rd and following antennal joints a small spot of 

 white pubescence is present. The apical half of the scutel- 

 lum is covered with a transverse patch of a black velvety 

 pubescence. 



The head is impunctate and shows a mesial line extend- 

 ing from the base of the labrum up to the front margin
