Long. corp. 2|— 2| lin., lat. 1-li lin. 



Oblong-ovate, robust, subpubescent, fcrrugineous. Head short, 

 transverse, slightly produced : between the eyes (immediately above 

 the base of the antennoe) is a broad transverse ridge, divided by a 

 medial depression so as to form two tubercles ; above this ridge are 

 three obsolete longitudinal carinations, reaching nearly to the base of 

 the head : the surface punctate and subpubescent. Thorax quadrate 

 (slightly transverse) ; the anterior angles depressed ; the sides slightly 

 marginate ; when viewed laterally, the base appears to be transversely 

 subdepressed ; the surface in front is raised, and forms medially two 

 tubercles ; the whole being clothed with thick squamosa pubescence, 

 fusco-ferrugineous, sparingly interspersed with flavous ; the surface 

 beneath this appears to be coarsely punctate. Scutellum minute, 

 triangular, flavous. Elytra broader than the thorax, robust, broadly 

 punctate-striate, clothed throughout with thick, close, mottled pu- 

 bescence ; pale ferrugineous, being interspersed with ashy-grey ; at 

 the base the colour is more decidedly rufo-fuseous. Antenna short, 

 robust ; the first joint broadly dilated ; the sixth to the tenth incras- 

 sated ; first to sixth flavous ; the base of the sixth and seventh to 

 ninth fuscous ; tenth and eleventh flavo- testaceous. Le(/s robust, 

 fusco-ferrugineous throughout. 



This species differs from II. tuberculatus by its considerably smaller 

 size, and from H. fuliginosus by the more ashy colour of its pubes- 

 cence, as well as by the coloration of the antennae ; from H. asper it 

 may be recognized by the three obsolete longitudinal carinations at 

 the base of the head, and from If. nodosus by the raised transverse 

 carination immediately above the base of the antennae.
