cinereous ; black, the basal joints of the antennae red, the 

 elytra each with four longitudinally arranged spots on the 

 disc — one at the base, acuminate-oval, one, oblong or slightly 

 oblique, one, rounded or subtriangular, and one, transverse, 

 subapical, the anterior two sometimes coalescent — and the 

 outer margin to near the apex, flavous or orange-yellow; 

 the head and prothorax closely, finely, the elytra roughly, 

 punctured. Head small, the eyes rather large ; antennae 

 short. Prothorax narrowed anteriorly. Elytra long, sub- 

 parallel, sharply costate from the humeral callus downward, 

 and also feebly costate on the disc ; the apices in $ feebly 

 truncate or rounded, in ? more or less emarginate, and with 

 the sutural and outer angles dentiform. 



g . Metasternum with two small, compressed, subcon- 

 tiguous tubercles in the middle behind. Ventral segment 5 

 deeply arcuato-emarginate, 6 long, compressed. Tegmen 

 simply bifurcate and clothed with long, projecting blackish 

 hairs at the tip. Penis-sheath drawn out into a long, slender 

 point at the apex.

Described from eight examples, four of each sex. The 

 teeth at the apex of the elytra in ? vary in length, and the 

 first and second spots on the disc are confluent in two of the 

 specimens of that sex before me. This is the undescribed 

 smaller Colombian form alluded to by Gorham in his descrip- 

 tion of A. octopustulatus. There is nothing intermediate in 

 the long series of the latter examined, and the present 

 insect may be distinguished from it by the elongated first 

 and second spots on the disc of the elytra, approaching 

 A. gorhami in this respect. The genital armature is very 

 similar. A. lebasi is not mentioned by Pic in any of his 

 various scattered papers on Astylus.

Elongate, narrow, shining, clothed with erect, black, 

 bristly hairs intermixed with scattered fine adpressed 

 cinereous pubescence, which is denser on the prothorax and 

 elytral suture of ? , the vestiture of the legs and under 

 surface cinereous ; black, the basal joints of the antennae 

 partly red, the elytra each with four longitudinally-arranged
