50. Conosoma championi, n. sp. 



Black, moderately shining, the posterior border of the thorax, the 

 elytra near the suture and the posterior margins of the first three 

 abdominal segments more or less obscurely reddish. Antennae long 

 and slender, much longer than the bead and thorax, the first four 

 joints and the last testaceous, the rest infuscate. Legs reddish- 

 testaceous. Length 3'5 mm. 



Stature of < '. binotatum, Grav., but the elytra much shorter. Head 

 very finely and sparingly punctured and pubescent. Antennae 

 long and slender, extending beyond the posterior angles of the thorax, 

 all the joints considerably longer than broad, the 2nd half the length 

 of the 3rd, the 3rd to the 5th subequal, the 6th to the 10th very 

 gradually decreasing in length, the 11th long, oval, longer than the 

 10th. Thorax very finely and moderately closely punctured, pubes- 

 cence short, greyish ; the posterior border obscurely and indetermin- 

 ately reddish. Elytra transverse, scarcely longer than the thorax, 

 obscurely reddish about the suture and the posterior margins, the 

 puncturation as on the thorax, but a little more distinct; the 

 pubescence as on the thorax; sides without setae. Abdomen 

 with the posterior margins of the tirst three segments more or less 



reddish; puncturation very tine and close in front, more sparing 



posteriorly ; sides with long black setae. 



$. Eighth dorsal segment cut into four pointed processes by three 



excisions, the lateral ones a little deeper than the central; the 



processes furnished with long black setae.

51. Conosoma walked, n. sp. 



Black moderately shining, the posterior angles of the thorax, 

 the posterior third of the elytra obscurely, and the posterior margins 

 of the abdominal segments rufo-testaceous. Antennae not much 

 longer than the head and thorax, the tirst four joints and the last 

 yellow testaceous, the rest infuscate. Legs reddish-testaceous. 

 Length 3 mm. 



hi build and colour so similar to the preceding, that it will be 

 sufficient to give the differential characters, which are as follows: 

 Smaller and less robust, with much shorter antennae, which are a 

 littlr- thickened towards the apex, the 3rd joint scarcely longer than 

 the 2nd, the 1th a little longer than the 3rd, the 5th to the 10th 

 gradually decreasing in length, conical. 8th to loth only slightly 

 lunger than broad, I lth ovoid, longer than the loth.
