Unifoi-m black ; sub-depressed uniforme, sp. n. 



Elytra pitchy-red; cylindrical semifiiscum, Newm. 



II. Antennae with the 3rd to 10th joints coriaceous below and fringed with hair. 



Elytra with humeral and lateral striae entire, dorsal 



stria short . peiiicillahim, sp. n. 



Note. — IT. hero-t, Fab., and rvjlpenne, Fab., are unknown to me, and I have not been 

 able to see the description of H. latum, Grouvelle. 



H. GiGAS and H. cuktipes. 

 These two species are extremely close, but I think certainly dis- 

 tinct. The one which I believe to be gigas is a little broader and less 

 convex than curfijies, and has the thorax a little broader in front. 



H. BEEYirOSSUM. 



This species seems to vary from four lines to eight lines in length. 

 Specimens in the British Museum collection are from India, Java 

 (type), Borneo. From these I have separated as varieties a series which 

 appear rather narrower and more elongate, and have the antennaa 

 a tinfle more slender. They come from Siam, Tenasserim, Birmah, 

 Timor, and the Philippines, with a doubtful one from Amboyna. They 

 measure from three to seven aud a half lines iu length, the extremes 

 being both from the Philippines. 



A single specimen from West Australia (four lines), I am unable 

 to separate from this species. 



HECTAETnnUM AUSTRALICUM, Sp. 11. 



Entirely black, rather broad, and very slightly convex. Thorax in front very 

 nearly as broad as the length ; lateral striae distinct, entire. Elytra with the 

 humeral stria entire, the dorsal and lateral strise very short. <? .

This species differs from S. ci/lindricum in being relatively broader, 

 and in having the thorax more distinctly broader in front ; in H. cy- 

 Undricum the sides of the thorax are nearly parallel in front, and the 

 elytra have no lateral stria. 



.Hectartiirum sociale, .9^. n. 



Thorax with the lateral stria interrupted behind. Elytra with the humeral and 

 dorsal strite well marked and nearly entire ; no lateral stria. Femora pitchy. $ .
