14. Ceuthophilus celatus, sp. nov. 



Body blackish fuscous, glabrous, liberally sprinkled with luteo- 

 testaceous giving it a speckled appearance in best marked specimens ; 

 some of these spots or dots are clustered in a more or less conspicuous 

 mediodorsal stripe, while others margin subequidistantly the posterior 

 border of all the abdominal segments or are submarginal ; on the pro- 

 notum and to a less degree on the meso- and metanotum they are liable 

 to coalesce and form vague and irregular patches and blotches ; the 

 fore and middle legs are luteous, more or less nifuscated especially at 

 the distal ends of the femora ; hind femora brownish fuscous, often 

 with an olivaceous tint, the scalariform markings nearly obsolete. 

 Antennae very slender, about twice the length of the body, the legs 

 rather short. Fore femora no stouter than the middle femora, about 

 a third ( ^) or a fourth (9 ) longer than the pronotum, and much less 

 than half as long as the hind femora, the inner carina with a subapical 

 spine sometimes accompanied by a few others near it. Middle femora 

 with a subapical spine sometimes accompanied by one or two others 

 on the front carina, and on the hind carina a not very long genicular 

 spine sometimes accompanied by two others. Hind femora, rather 

 slender, tapering almost regularly, about three and a half times as long 

 as broad, considerably more than twice as long as the fore femora, 

 with no raised points upon the surface, the outer carina very finely 

 denticulate ((?) or wholly or almost wholly unarmed (9), the inner 

 carina feebly and very finely serratulate, the intervening sulcus narrow. 

 Hind tibiee straight in both sexes, a little longer than the femora, 

 slender, armed beneath with a single subapical spine besides the apical 

 pair; spurs opposite or subopposite, the basal at the end of the proxi- 

 mal fourth of the tibia, no longer than the tibial depth, set at an angle 

 of about 45° with the tibia and divaricating about 60° ; inner middle 

 calcaria considerably longer than the outer, more than twice as long 

 as the others or as the spurs, but shorter than the first tarsal joint. 

 Hind tarsi a little less than half as long as the tibia, the first joint 

 scarcely as long as the rest together, the second much more than 

 twice as long as the third and with it longer than the fourth. Cerei 

 slight, tapering regularly, about three fourths as long as the femoral 

 breadth. Ovipositor straight, tapering on the proximal, slender and 

 equal on the distal half, somewhat more than half as long as the hind 

 femora, the tip very gradually attenuated and very slightly upcurved, 

 not very finely pointed, the inner valves rather feebly crenulate.
