minute linear white spot is to be found on each side of the 

 prothorax in front of and below the lateral spine. 



Although the species has a superficial resemblance to some 

 of the typical species of Monohammus, its structural characters 

 are distinctly those of the genus Tmmotes ; it has the form 

 of head and eyes, the form of prosternum, tlie tuberculation 

 of mesosternum, and the broadly truncate and laterally toothed 

 last abdominal ventral segment which are characteristic of 

 this genus. Each elytron is narrowly rounded at the apex, 

 but wants the terminal tooth which is present in many species 

 of the genus. The front of the head is slightly broader than 

 in the majority of its congeners. 



The two female specimens in the Museum collection were 

 presented many years ago by Sir E. Belcher and were col- 

 lected during the voyage of H.M.S. ' Sulphur ' around the 

 world. No indication of locality is attached to the specimens, 

 but it may, I think, be safely asserted that they are South or 

 Central American.

Head with the front minutely and retlculately ridged, the 

 eyes bordered with a reddish-brown pubescence ; the vertex 

 punctured behind and with a glossy black, somewhat raised, 

 longitudinal line in the depression between the antennal 

 tubercles. The prothorax with the lateral spines acute, the 

 disk minutely and irregularly ridged, with a distinct feeble 

 tubercle or callosity in the middle ; the pubescence sparse, of 

 a reddish-brown colour, and arranged somewhat in longitu- 

 dinal lines — three on the disk and one on each side below the 

 lateral spines. Elytra granular at the base, with a reddish- 

 brown pubescence, almost limited to two longitudinal bands 

 on each elytron, one narrow sutural, the other broader and 

 fainter, lateral, but not reaching the margin. In addition 

 there are three larger torn patches and some smaller spots of 

 white pubescence on each elytron ; the first patch is just 

 behind the middle of the base, the second antemedian, and 

 the third postmedian. The apex is rounded and appears not 

 to be armed with teeth. (In the single specimen the apex ia
