6. Ceuthophilus grandis, sp. nov. 



Body dark luteo-castaneous very heavily marked with blackish or 

 blackish fuscous, which is heaviest at the posterior margins of all the 

 segments, along the front margin of the pronotum, and in a stripe 

 bordering the broad mediodorsal rufo-luteous stripe of the pronotum ; 

 the anterior lower angle of the pronotum, and to some extent that 

 of the other thoracic segments, are dull luteous, merging with the 

 luteous of the central portion of the descending lobes ; on the abdomen 

 the darker colors prevail above to such a degree that the luteous 

 appears to be maculate on a dark ground ; antennae and legs luteo- 

 testaceous, more or less though generally feebly infuscate, the hind 

 femora with fuscous scalariform markings, apically broadly marked 

 with fuscous but preceded by a broad more or less clearly marked 

 luteous annulation. The antennse are slender except near the base 

 and fully four times as long as the body, the legs very long and 

 slender. Fore femora scarcely stouter than the middle femora, barely 

 half as long as the hind femora, two thirds {$) or three fifths ( 9 ) as 

 long again as the pronotum, the inner carina with 3-4 spines none of 

 them very long nor very unequal. Middle femora similarly armed 

 on the front carina and on the hind carina 3-4 spines besides the 

 moderately long genicular spine. Hind femora as long as the body, 

 very little more than twice as long as the fore femora, pretty stout at 

 base, but with the slender portion much produced, the apical third or 

 in the female even more than that being subequal, the whole being in the 

 male nearly four and a half times longer than broad, the surface above 

 and on both sides just beyond the middle with a few scattered raised 

 points, the outer carina armed throughout all but extreme base with 

 8-12 distant, not greatly unequal, subequidistant spines, the longest 

 scarcely so long as the tibial spurs but tumid at base ( (J ) or with 

 similarly distant feeble serrulations (9)5 the inner carina sjiarsely {$) 

 or very sparsely ( 9 ) serrulate, the intervening sulcus narrow. Hind
