T. Lewisii (Bates) var. Bhamoensis, Bates, Ann. Mus. Civ. 

 Genova, Ser. 2.% Vol. VII, p. 6. 



Bhamò; Teinzò. 



Having examined a larger series of this form I think it de- 

 serving of specific rank ; it is generally a larger insect than 

 T. Lewisii, the head and thorax are bluish-green or brassy-green, 

 the latter almost always much more widely dilated and a little 

 more perceptibly sinuated just before the obtuse hind angles, 

 the base being also much more punctured on each side. The 

 sinistral mandible is feebly transverse-striated along the edge, 

 as in T. Lewisii and T. concinna (Castelnaa). Long. 17-20 millim. 



222. Trigonotoma chrysites, n. sp. 



T. Bhamoensi quoad formam simillima sed quoad colores 

 T. concinnae similis, a qua differt thorace minus elongato-ovato 

 et basi utrinque punctate. Mandibula sinistra intus transversim 

 striata basique supra (sicut in T. Lewisii) grossius striata. Caput 

 et thorace splendide aurato-cuprea, hoc lateribus late rotundato, 

 ante basin leviter sinuato sed angulis (elevatis) obtusis, basi 

 utrinque fere usque ad lineam dorsalem punctate. Elytra pur- 

 purascenti-nigra, profunde crenulato-striata, interstitiis subaequa- 

 libus. — Long. 18-20 millim. c/ 9.

Rather smaller (21-22 millim.) than the unique example 

 described by Chaudoir (24 millim.) from Cochin China. The two 



mandibulis omnino laevibus. Thorax medio fortiter rotundatus, postice paullo magis 

 quam antice angustatus , lateribus prope angulos posticos leviter sinuatis , sed 

 angulis posticis obtusis etsi distinctis, fovea utrinque basali grosse punctata, sulculo 

 mediocriter elongato, lateribus posticis sat alte reflexis. Elytra comparate elongata, 

 profunde crenato-striata, striola scutellari valde elongata. j" palpi labiales articulo 

 apicali valde triangulariter dilatato. — Long. 24 millim. j".
