Dikoya. 



Very much larger than T. triangularis and differently 

 coloured. Approaches much nearer T. tropicus, from which 

 it differs chietiy in the feebler stride and the situation of the 

 anterior setiferous puncture, which is quite outside the fourth 

 stria, on the smooth part of the elytron, and not in the fourth 

 interstice as expressly stated by Nietner of T. tropicus, 

 and as shown in tlie Ceylonese specimens referred to that 

 species. 



Tachys spilotus. 



T. bistriato affinis, sed multo major elytrisque flavo-guttatis etc. 

 Elougato-oblongo-ovatus, subdepressus, castaueo-niger subopales- 

 centi-nitens ; antennis fuscis, articulis 1-3, palpis, pedibus elytris- 

 que utrinque guttis parum distinctis duabus (prima subhumerali, 

 secunda transversa ante apicem) liavo-testaceis ; sulcis froutalibus 

 brevibus, latis ; tborace trausversim quadrato, postice medio- 

 criter angustato, angulis posticis rectis, margine basali, pedunculo 

 et scutello testaceis ; elytris utrinque striis 3 baud acute incisis, 

 puncto dorsali in stria tertia sito.

Colombo. 



Closely allied to the European T. histriatus, but much 

 larger, and the elytra more glossy and with slight opalescent 

 reflections ; the thorax is much broader and is differently 

 formed near the hind angles, these being rectangular or even 

 acute, and the hind margin from the angle to the slight median 

 lobe being much less oblique. The single dorsal puncture is 

 in the middle of the elytra ; the second puncture, as in all the 

 species of this section, lies within tlie apex of the recurrent 

 striole.

Bogawantalawa. 



One example, exactly agreeing with a specimen named by 

 Wollaston from the Cape-Verd Islands. The recurved stiiole 

 is wanting, or, what seems more likely, removed nearer to the
