12. CEUTHOPHILUS SECLUSUS, sp. nov. 



Glabrous, blackish fuscous, heavily and irregularly marked with 

 luteous becoming rufo-luteous dorsally, the whole surface about equally 

 divided between the fuscous and luteous, but the fuscous prevails 

 dorsally, the luteous laterally ; there is an interrupted and irregular 

 broad rufo-luteous mediodorsal band on the thoracic segments, and the 

 inferior margins of at least the pronotum are bordered with luteous, 

 but the other luteous markings are mostly in the form of rather 

 irregularly scattered, more or less irregularly confluent small round 

 spots, often becoming blotches of great irregularity on the thorax ; legs 

 dull luteous, the femora infuscated especially apically and the hind 

 femora heavily marked in a scalariform pattern as well as apically 

 annulate with fuscous. The antennae are slender and apparently about 

 twice as long as the body, and the legs slender and moderately long. 

 Fore femora not stouter than the middle pair, varying greatly in 

 length in the sexes, in the male being only a little less than half as 

 long as the hind femora and more than a third as long again as the 

 pronotum, in the female very much less than half as long as the 

 hind femora, and not a fifth longer than the pronotum, the inner 

 carina with two spines, at least the subapical rather long. Middle 

 femora with 2-4 spines on the front carina and on the hind 

 carina 1-2 spines besides a not very long genicular spine. Hind 

 femora about as long as the body, a little more than twice () or 

 considerably more than two and a half times ( 9 ) as long as the fore 

 femora, slender and very gradually tapering, about three and three 

 quarters times as long as broad, the apical fifth subequal, with no 

 raised points upon the surface, the outer carina minutely and inequidis- 

 tantly spinulate or subserrate, in the female the serrations much sub,- 

 dued, the inner carina similarly but more finely armed in both sexes, the 

 intervening sulcus narrow. Hind tibiae straight, scarcely longer than 

 the femora, slender, armed beneath with a single preapical spine besides 

 the apical pair; spurs subalteruate, the basal about the end of the
