rugose^ clytr.-i and their uniform pale coloration. I have not now 

 the type of X. hirUpmnis before me but as I have stated par- 

 ticularly in my description , that the elytra of that species are 

 not rugose I must look upon the present insect as distinct; 

 there are three specimens before me. 



l;24. Xenoda nigricollis, n. sp. — Black, the apical two joints 

 of the antennae llavous, elytra rather strongly rugose, aeneous, 

 purplish or blue. 



c/. Antennae with the intermediate joints widened and swol- 

 len, furnished with a long spine. 

 Length 3 linens. 



This species agrees in all structural characters with A', sjilni- 

 coniis, Baly but the thorax is entirely black and the elytra are 

 more strongly rugose and very sparingly pubescent, the under- 

 side and legs are black , the antennae have the intermetliate 

 joints greatly dilated and widened as in the tj'pical form ; the 

 female has , ;is usual , simple antennae , all the joints , w ith 

 the exce})tion of the small second one , are of nearly equal 

 length; four s})ecimens are before me which were obtained at 

 Si-Rambé. 



1:25. Xenoda abdominalis, n. sp. - - Dark purplish, finely pube- 

 scent, the antennae black, the apical two joints Havous, thorax 

 impunctate, elytra finely rugose, abdomen llavous. 



c/'. The intermediate joints of the antennae moderately dilated. 

 V . Antennae simple and filiform. 

 Length '2 lines. 



Head inii)unctate, the vertex convex, frontal tubercles strongly 

 raiseil, transverse, lal)runi and })alpi (sometimes) llavous, ant'jn- 

 nae extending beyond the niiddle of the elytra, black, the apex 

 of the ninth joint and the apical two joints llavous, the third 

 to the fifth s\\ ollen, but longer than broad, the following joints 

 normal, the apical tv\o elongate, thorax of usual shape, short 

 and transverse, sulcate throughout, elytra finely rugose, clothed 

 with black pubescence, tibiae and tarsi blackish, abdomen lla- 

 vous.
