32. Ceuthophilus bicolor, sp. nov. 



Body glabrous, luteo-testaceous, with a broad subdorsal blackish 

 fuscous baud on either side, leaving between them a broad bright stripe 

 the whole length of the body, next the stripe sharply delimited, later- 

 ally more or less broken, ragged and fading away, uan*ow on the pro- 

 notum where it is infringed upon by a large central luteous spot on 

 the sides, broader and profusely spotted with luteous posteriorly, the 

 lower portions of the sides almost wholly pallid luteous with cloudy 

 iufuscations, the extreme margin testaceous ; legs luteo-testaceous, the 

 hiud femora feebly marked with fuscous in a scalariform pattern and 

 tipped with fuscous. The antennae are slender and at least three times 

 as long as the body, and the legs slender and rather short. Fore 

 femora no stouter than the middle pair, much less thau half as long 

 as the hiud femora, a fifth as long again as the pronotum, the inner 

 carina with two or three spines, the preapical much longer than 

 the others. Middle femora with the front carina similarly armed 

 and the hind carina with one or two spines mesially situated besides 

 a long genicular spine. Hind femora as long as the body, two and 

 a half times longer than the fore femora, stout, tapering with great 

 regularity to the slightly enlarged genicular lobes, scarcely more than 

 three times as long as broad, the inner surface above beyond the 

 middle with a small cluster of raised points, the outer carina armed 

 on the stouter part of the femora with an open series of serrula- 

 tions, developing distally into spines, the last two much larger than 

 the others and half as long as the tibial spurs, followed by 3-4 slight 

 spines just before and on the genicular lobes, the inner carina 

 equally but inequidistaiitly and rather sparsely spinulate, the inter- 

 vening sulcus broad. Hind tibiae straight, slender, more than a tenth 

 longer than the femora, armed beneath with a single subapical spine 

 besides the apical pair ; spurs subalternate, the basal before the end of 

 the proximal third of the tibia, nearly or quite twice as long as the 

 tibial depth, set at an angle of about 50° with the tibia and divaricat- 

 ing about 1 10°, their tips incurved ; inner middle calcaria greatly
