LONGICORN COLEOPTERA FROM BURMA 49 



Siam are specifically distinct from those from Borneo. The elytra 

 in the new species are more parallelsided, the scape of the an- 

 tennae is less elongated , and less abruptly thickened at the 

 apex, is rather shorter than the third joint, and carries a reddish 

 pubescent patch near the middle. In corallina the elytra are 

 considerably narrowed from the base backwards , the scape of 

 the antennae is rather abruptly thickened at the apex, is slightly 

 longer than the third joint and has not a reddish patch. 



123. Mesosa Q) subfasciata, sp. n. Pube fulvo-brunnea grisea- 

 que, fusco-ììiaculala, oblecla; elytris fascia transversa media, lata 

 sed irregulariter marginala, pallidiore , ante hanc fasciam fere 

 totis fuscis; apicibus anguste rolundatis ; antennis fuscis, scapo 

 griseo, articulis 3*^ et sequentibus basi cinereis. Long. 11-15 mm. 



Garin Mts. (district of Gheba), alt. 900-1100 m. 



This species has the head slightly less concave, the prothorax 

 more rounded at the sides, and the elytra more attenuate 

 posteriorly than in Mesosa nebulosa, Fabr., but otherwise agrees 

 with it fairly well in structural characters. The antennae of 

 the male are more than half as long again as the body. In 

 this sex also there is a narrow transverse pilose depression 

 towards each side of the anterior border of each of the three 

 intermediate abdominal sternites. Each depression is concealed 

 more or less by a fringe of fulvous hairs attached to the hind 

 margin of the sternite immediately in front. The antennae of 

 the female reach to a little beyond the apex of the elytra. 



124. Mesosa Obscura, sp. n. Griseo et fulvo-griseo pubescens; 

 punctis maculi:ique fusco-brunneis; capite inter anlennas sat fortiter 

 concauo; prothorace supra leviter trituberculato, basi npiceque rede 

 lineato- sulcato et panilo pone apicem sinuato-impresso, lateribus 

 leviter inaequalibus et obsolete rugosis, elytris punctatis, fuloo-griseo- 

 pubescentibus, maculis punclisque fusco-brunneis, corpore subtus 



(') The genus Mesosa was first characterized by Latreille (Règne Animal, 2 d« Edit. 

 Tom. V, p. 124); tliough Serville is usually cited as its author. Aplocnemia , Ste- 

 phens (Illustrations of Brit. Eat. IV (1831) p. 236), which is a synonym of Mesosa. 

 was not described until two years later.
