40. Ceuthophilus mexicanus, sp. nov. 



Pallid, probably in life luteous, heavily overlaid with dark fuscous 

 markings ; pronotum mostly fuscous, with a mediodorsal luteous 

 thread, expanding near anterior and posterior margins into a small 

 rhomboid spot and with a large posterior central luteous spot in the 

 middle of each side, the extreme inferior margin also luteous ; meso- 

 and metanotum with a large central luteous spot on either side often 

 reaching the border posteriorly and a posterior median similar spot, 

 the two sometimes confluent and often very irregular ; abdominal seg- 

 ments, when darkest, with a large luteous spot on each side and a 

 median anterior one, but the fuscous is often largely reduced ; legs 

 luteous, more or less infuscated, especially on the distal halves of 

 the fore and middle femora, the hind femora rather heavily marked 

 with fuscous in a scalariform pattern. Antennae very slender, at least 

 three times as long as the body, the legs slender and rather long. 

 Fore femora scarcely stouter than middle femora, a fourth longer than 

 the pronotum and half as long as the hind femora, the inner carina 

 with two spines, both long but especially the subapical. Middle femora 

 with 1-2 spines besides a very long subapical spine on the front carina, 

 and the hind carina with 1-2 spines besides a long genicular spine. 

 Hind femora as long as the body and twice as long as the fore femora, 

 rather stout at base but slender in the distal third, nearly thi'ee times 

 as long as broad, with a few feeble raised points on the distal half of the 

 extreme upper surface, the outer carina with 1-4 very small distant 

 spines on the apical half, the inner carina with 8-10 minute points, 

 the intervening sulcus narrow. Hind tibi® straight, slender, somewhat 

 longer than the femora, armed beneath with a single subapical s{)ine
