yellow, abdomen fuscous-black ; head and prothorax of the normal 

 shape and sculpture, the latter is somewhat elongated ; the elytra 

 are ob-ovate with the shoulders much rounded and sloping, 

 shagreened, ver 1 ' briefly pubescent, plainly costulate, there is a 

 yellowish triangular patch in the scutellary region, an elongated 

 patch or band beginning at a short distance from the base and 

 running on the fourth and sixth intervals, including the costa, and 

 not reaching quite the median part, a quadrate or elongato-quadrate 

 one extending on the first, second, and third costules, and a similar 

 one set on the outer angle of the posterior edge and coalescing with 

 the narrow yellowish margin, which is slightly dilated ; towards the 

 median part these markings are not always very plain, but they are 

 never completely obliterated. 



It is a near ally of B. oblitcrus, Pering., in which, however, the 

 elytra are more quadrate at the base owing to the shoulders not 

 being strongly sloping, and the prothorax shorter. 



Length 5^74- mm. ; width 2^-3-i- mm.

BRACHINUS UMVOTIANUS, n. sp. 



Black, opaque ; antennae fuscous-black, joints thick ; femora 

 yellowish-red but infuscate at the knees ; head covered with deep 

 punctures more closely set on the posterior than on the anterior 

 part, and clothed with a long, very dense, erect, black pubescence ; 

 prothorax elongated, sinuated laterally from the third part of the 

 length, and with the anterior not very cordiform, deeply grooved 

 longitudinally in the centre, covered with very closely set, nearly 

 contiguous deep punctures, and clothed with the same erect black 

 pubescence as the head ; elytra with the humeral part strongly 

 rounded, and therefore very little prominent, gradually arnpliated 

 thence to the posterior part, very plainly costate, the costae tectiform 

 and sharp, the intervals are shagreened and both intervals and costae 

 are clothed with a sub-erect, very dense fuscous pubescence, the 

 epipleural fold is punctate, the punctures setigerous ; under side and 

 legs closely punctate and pubescent. 



Length 11 mm. ; width 5 mm. 



Allied to B. tibialis, Pering., but the humeral angles are not quite as 

 obliterated, the antennal joints are thicker, the punctures of the head 

 and prothorax are deeper and more closely set, and the pubescence 

 there is longer and denser.
