HeCTABTURUM DE.TECTUM, Sp. n. 



Very depressed and rather broad. Uniform black. Lateral stria of thorax in- 

 terrupted behind. Elytra with the humeral and dorsal strico well defined ; lateral 

 stria absent. ? . Long. 6^ lin., lat. 2 lin. 



This species is separated from H. sociale on account of its de- 

 pressed form ; the thorax is, moreover, more regularly widened in 

 front. The joints of the antennae, seen from below, are a little elongate, 

 and the triangular notch on the 7th to 10th joints is very large and 

 opaque.

Note. — H. trigenihium, sociale, and dejectum have no fovea in the centre of the 

 posterior margin of the thorax. 



PIectabtiietjm gemelliparum, Newm. 

 Mr. Murray seems to have overlooked the description of this 

 species, and has evidently re-described it under the name of H. Smithii. 



Hectartitrum rxiFORME, sp. n. 



Rather depressed. Thorax with the lateral stria entire ; no central fovea to tho 

 posterior margin. Elytra with a second sutural stria, and the humeral stria entire ; 

 the dorsal stria well marked, but slightly abbreviated behind ; the lateral stria is 

 faintly indicated. The antennse are very long ( ? ), the 3rd to 10th joints are a little 

 elongate (especially the 5th and Gth), and are oval in their lateral outline, the 11th 

 joint is elongate and arched. Long. 5 and G\ lines. 



This species has the triangular notch at the apex of the antennal 

 joints below, very small and almost reduced to a puncture.

Hectarthrum penicillatum, sp. n. 



Nigrum, nitidum, depressum ; antennis longis, suhtus rugulosis et 

 penicillatis ; elytris stria humerali haud ahhreviata, dorsali brevi, later- 

 ali (hand bene impressa) apicem attingenti. Long. %\ — 9:^- lin. 



Head witli a slight obtuse tubercle immediately above the clypeal impression 

 Antennae longer than the head and thorax together, the 3rd to 10th joints compressed 

 and narrowed at their base, these joints more or less coriaceous below and fringed 

 with stiff ferruginous hairs. Thorax with the lateral stria very slightly impressed 

 behind. Elytra with one sutural stria ; the humeral and lateral striae entire (the 

 latter very lightly impressed), tho dorsal stria much abbreviated.

This species somewhat resembles K. hrevifossum ; it is rather 

 broader and more depressed, and is at once separated from all the 

 species of the genus by the structure of the antennae, which may 

 possibly necessitate the formation of a, new genus for its reception.
