more or less testaceous; sculpture consisting of a sutural row of 

 fine somewhat obsolete punctures, and a distinct row from the 

 humeral angle to the posterior margin of about twelve punctures; 

 the pleura have also an irregular series of eight or nine punctures, 

 otherwise the surface is impunctate and shows no sign of ground- 

 sculpture. Abdomen pitchy, the extreme apex, the posterior 

 margins of the segments very narrowly, and the explanate lateral 

 margins entirely, bright yellow- testaceous ; puncturation very 

 fine and sparing ; pubescence stiff and scanty.

3G. Diochus pulchellus, n. sp. 



Pitchy-black, shining; thorax entirely, apex of elytra broadly 

 reddish-testaceous; abdomen pitchy-red, the apex testaceous; 

 antennae, mouth-parts, and legs testaceous. Length 3 mm. 



A brightly-coloured, shining insect, Head subtriangular, longer 

 than broad; front with a minute tubercle in the middle line on a 

 level with the bases of the antennal tuberosities; sculpture con- 

 sisting of a row of four punctures on either side — one at the base 

 of the antennal tuberosity, a second a little behind the level of the 

 posterior border of the eye, a third at an equal distance from the 

 second as this is from the first, and a fourth in front of the base of 

 the head; temples with a few fine setiferous punctures; ground- 

 sculpture very fine, transverse, strigose. Antennae reaching the 

 posterior margin of the thorax, the 2nd and 3rd joints of equal 

 length, 4th and 5th subequal, a little longer than broad, the 6th 

 as long as broad, the 7th scarcely, the 8th to 10th slightly, transverse. 

 Thorax red, widest at the rounded posterior angles, longer than 

 broad, the sides slightly converging anteriorly to the widely rounded 

 anterior angles ; disc with a row of three setiferous punctures con- 

 verging behind on either side, and also with two externally near the 

 anterior angles, and a minute one at the posterior angles ; the sides 

 setose. Elytra pitchy-black, shining, the sides, posterior angles 

 and apical margin broadly reddish-testaceous; shorter than the 

 thorax, transverse, widened posteriorly; sculpture consisting of a 

 row of four or five obsolete, scarcely visible setiferous punctures 

 on each disc; sides with rather long dark setae. Abdomen pitchy- 

 red, the 5th (visible) segment reddish-testaceous, the 6th testaceous; 

 finely and closely punctured and pubescent throughout, the sides 

 setiferous, each segment also with erect setae.
