very obtuse, barely as long as the two preceding ; outer joints 

 somewhat distant and perfoliate. Mentum ample, trapezoidal, 

 truncate. Maxillary palpi with the third joint very much longer 

 and thicker than the second; fourth small, very slender, oblique. 

 Ligula with two minute and subparallel slender processes descend- 

 ing subvertically from the apex, also with two long setae ; labial 

 palpi distinctly three-jointed, the first stouter and much longer than 

 the second ; third slender, nearly as long as the first two. Protho- 

 rax rather small, transverse, the hypomera strongly iflflexed but in 

 part visible from the side. Elytra wide, well developed, transverse. 

 Abdomen broad, parallel, the first three dorsals narrowly and deeply 

 impressed at base, fourth and fifth equal. Middle coxas very widely 

 separated, the mesosternal process scarcely more than one-third as 

 wide as the interval separating them, gradually, feebly deflexed, 

 abruptly and obtusely pointed or narrowly rounded at apex, ex- 

 tending through three-fourths of the coxal length, with its apex 

 superposed upon the broadly rounded apex of the very short and 

 wide metasternal process. Metasternum well developed, the side- 

 pieces parallel, the epimera projecting slightly behind the elytra. 

 Legs short but slender, the tarsi short, slender, distinctly 4-5-5- 

 jointed, the four basal joints of the posterior equal, the fifth longer 

 than the preceding two combined ; ungues rather long, slender, 

 feebly arcuate. 



The wide vacant space separating the middle coxee from the sides 

 of the mesosternal process is probably a constant feature. This 

 genus belongs near Hoplandria, from which it differs in habitus, in 

 the parallel sides and distinct basal angles of the prothorax, much 

 longer antennae with a longer basal joint, entire absence of the 

 terminal appendage of the fourth palpal joint, and, especially, in 

 the form of the ligula, which in Hoplandria has a long slender 

 almost simple terminal process ; it also differs in its narrow, 

 obtusely pointed mesosternal process and parallel abdomen. 



Several of the South and Central American species described 

 under the name Brachida, will probably have to be referred to 

 Trichiusa ; in fact the tuberculate external apical angles of the 

 elytra in Brachida batesi Shp., points almost unmistakably to a 

 relationship with Hoplandria.' In the European representative of 



^ In this connection the small tubercles near the inner apical angles of the 

 elytra in Brachida notha are remarkable, in view of the four-jointed middle 

 tar.si.
