DEMOXAX. 



281 



Many of the species included in this genus are narrow and 

 elongated like those of Wiaphwna, Pasc. ; others, with subglobose 

 prothorax and relatively shorter elytra, resemble the majority of 

 forms belonging to the genus Ccdochjtus, Eairm. They are dis- 

 tinguished irom both the above genera by the presence of spines 

 at the apex of the third, fourth and sometimes also the fifth and 

 sixth antennal joints. In certain species such as those on which 

 the genera Grammogmphus and Elezira were founded, the antennal 

 spines are very minute and liable to be overlooked without close 

 exan)ination under the lens ; in the majority they are quite distinct. 



The lateral margins of the elytra are in the more typical forms 

 nearly straight, and the nietathoracic episterna appear broad and 

 parallel-sided; in others the lateral margins are moreor less dis- 

 tinctly sinuate near the middle, and the metathoracic episterna 

 appear narrowed in front and widened out posteriorly. 



I. Lateral margins of eli/tra nearly straight ; episterna of 

 metaihorax parallel-sided.

Elongate ; densely covered above with buff-yellow pubescence ; 

 prothorax narrowly bordered with yellowish-white pubescence 

 at the base, marked with a narrow, asperate, slightly raised, 



black band along the middle and a 

 small, pubescent, black spot at each 

 side in front of the middle ; each 

 elytron with (1) a short dorsal dark 

 brown vitta near the base, united 

 transversely just behind the scutellum 

 with the corresponding band of the 

 other elytron; (2) a narrow, dark 

 brown band that runs straight back 

 from the shoulder to the apical fourth ; 

 (3) an obhque band that extends from 

 the suture at about cue-third from the 

 Iiase and ends in a small spot placed 

 close to the hinder end of the lateral 

 band ; (4) a V-shaped spot placed a 

 little behind the end of the preceding 

 two bands ; the epipleure and lateral 

 edge also dark brown ; body beneath 

 pj 94 covered with yellowish-white pubes-
