The species is evidently veiy nearly allied to //. bUu-y 

 Linn. The colour of the elytra is ahuost the saina, but the 

 pubescence has a slii^-Jit gi-eenish or yellowish tluL^c. Tiie 

 ridges of the j)rothorax are more numerous ami a little less 

 regularly transverse. The fifth joint of the male auteiime is 

 without a distinct sj^ine. The head is more distinctly carinate 

 between the U[)j)er lobes of the eyes,

Long. 37-41, lat. 10-12 mm. 



JIab. Ijrazil. 



Blackish brown, with a pale greyish pubescence, with t'le 

 emargination of the eyes covered with a bright golden pubes- 

 cence. Prothorax crossed above by about eleven transverse 

 ridges in addition to the raised anterior and posterior borders; 

 the sides each with two tubercles — one at the middle, the 

 other, distinct though obtuse, a little behind the anterior 

 margin. Elytra elongate, feebly and somewhat sparsely 

 punctulate, reddish brown, with a faint greyish pubescence, 

 each truncate and bispinose at the apex. 



This species may be distinguished from H. latus, Linn., 

 and its allies by the punctuation of its elytra, by the second 

 distinct tubercle on each side of the prothorax, and by havino- 

 the fifth joint of its antennie equal in length to the third. 



In H. batusm\A H. mexicanus the fifth joint of the antennas 

 is a little shorter than the third ; the prothorax has a slight 

 thickening of the ridges, or callosity, on each side near the 

 anterior margin ; the elytra are almost destitute of punctua- 

 tion beyond the excessively minute pits from which the hairs 

 of the j)ubescence spring. 



Jn 11. punctulatus the stridulating surface of the meso- 

 uotura is less finely striated than in allied species ; but 1 do 

 not yet know whether this character may be relied on as a 

 specific distinction. 



H. carthagence (Guer., MS.), a variety of II. batus^ Linn., 

 with brown or reddish-brown elytra, which is found in 

 Colombia and Panama, has a strong resemblance t3 the 

 present species.
