alternis vix tessellatis, antennis longiusculis crassis infuscato-ferrugineis, articulo tertio secundo 

 multum longiore. 

 Mas, pedibus vis robustioribus : tibiis omnibus mox pone apiceni internum spina parva acuta (in 

 posticis minutissima acutissima) armatis ; anticis apicem versus incurvis ; posterioribus (sed prse- 

 sertim posticis) rectis; posticis ad apicem baud explanatis (omnino simplicibus). 

 Fcem. paulo major ; pedibus vix gracilioribus et baud brevioribus, simplicibus.

A. elongate-ovate, piceous-black, piceous, or brownish-piceous, and sparingly clothed with a robust, 

 decumbent, brownish-cinereous, or entirely cinereous pubescence. Rosti-um slightly dilated at its 

 apex; rather distinctly sculptured, having a tendency to be longitudinally strigulose ; and with 

 a deep central channel between the eyes. Prothorax widest just behind the middle ; rather 

 roughened and remotely punctured, the punctures extremely large, and sometimes (though not 

 always) deep, — the spaces between them being beset with most minutely and delicately impressed 

 points*. Elytra deeply punctate-striated; densely beset with very elongated, erect, extremely 

 fine, and woolly additional hairs, which are of a softer nature than those of any of the other 

 species ; the alternate interstices having only the slightest possible tendency (which is sometimes 

 not at all perceptible) to be longitudinally tessellated with denser patches of the pubescence. 

 Antenna rather long, and exceedingly robust; their scape being dull ferruginous, and the 

 remainder more or less darkly infuscated, or picescent : the second joint of their funiculus 

 immensely longer than the first. Leffs more or less brownish-testaceous, or fusco-piceous : the 

 tarsi paler, their terminal joint being rufo-testaceous. 

 Male, with the legs scarcely more robust than the female : all the tibia armed with a small, acute 

 spine (which in the hinder pair is very small, and exceedingly acute) at a short distance behind 

 their inner apices ; the two anterior ones considerably incurved towards their extremity ; the four 

 posterior ones (especially the hinder pair) straight ; the hinder ones not expanded at their extre- 

 mity, but entirely simple. 

 Female rather larger; mth the legs vei-y slightly slenderer, but not shorter, and simple. 



A most distinct species, differing from the remainder of the genus here desci'ibed, 

 not only in the exceedingly soft, or woolly nature of the elongated erect hau's with 

 which it is clothed, but likewise in its deeply sculptured sm*face (that of the pro- 

 thorax, as already stated, presenting a very peculiar structure), in the thickness 

 and robustness of its antennte, which have the second joint of their funiculus 

 hnmensely longer than the first, and in the small, acute spine with which the 

 internal apex of all the tibise of its male sex are furnished at a short distance from 



* These intermediate points are scarcely perceptible except beneath the microscope : but when thus 

 viewed, the sculpture has much the appearance of that which forms such a peculiar featiu-e of the Lapa- 

 rocerus morio, — except that the superior punctures are immensely larger, and the iuferior ones smaller 

 stiU (aud less numerous) than those of that insect.
