350 Mr. C. J. Gulian on some Longicorn 



grooves. Scutellum luteous white. Eljtra almost impunc- 

 tate and altogether without granules, each with eleven or 

 twelve whitish or luteous-white spots differing somewliat in 

 size and form, tlie smallest being placed near the scutellum ; 

 four of the spots are placed close to the outer margin, one 

 (rather large) at the apex, another in the basal depression 

 above the shoulder, and the remaining four or five on the 

 disk in such a position that the whole of the spots on tlie 

 elytra, excluding the two large ajncal ones, form four some- 

 what irregular transverse series. On the underside a spot on 

 each side of the mesosternum, an oblique patch on each side 

 of the metasternum, and a row of five spots on each side of 

 the abdomen are of a luteous-white colour, the rest of the 

 ventral surface except along tiie middle having a faint greyisli 

 pubescence; the legs are also faintly grey, with a dorsal spot 

 near the apex of each femur, tlie proximal half of the tibias, 

 and the upperside of the tarsi luteous white. Antennse of the 

 male more than half as long again as the body ; each of the 

 joints narrowly ringed with luteous white both at the base 

 and apex, except the first, which has a spot only near the 

 apex, and the last three or four, which are almost entirely 

 luteous white. Mesosternal process with a prominent 

 tubercle, the anterior face of which is almost perpendicular, 

 while the ventral face slopes downward in front.

This species somewhat resembles the preceding one, but is 

 readily to be distinguished by the following characters : — The 

 prothorax has two interrupted luteous-white bands on the 

 disk and the postmedian tubercle on the disk is ratiier strongly 

 raised and shows no trace of a notch or impression. The 

 elytra are sparsely but distinctly granulate on the basal sixth ; 

 each is marked with about nine or ten larger and twelve to 

 fourteen smaller luteous-white spots, all of which are more or 

 less rounded in outline and arranged without any definite 

 order. 'J'he underside of the body is covered with a rather 

 faint bluish-grey pubescence, and there is a patch on each 

 side of the prothorax and a spot on each cheek of a somewhat 

 more distinctly bluish tint. The rings of pubescence on the
