 temples (subg. Meotica , Aleuonota ot al.). The antennae are of very differ- 

 ent length and thickness, and thereby often afford very important identi- 

 fication characters for subgenera and species. Only in a few c.-ses are the 

 mandibles somewhat protruding (subg. Halobrechta ) . one of tnese as a rule 

 armed v, ith a small tooth on the inner side. The third joint of maxillary 

 palpi is longer than the second, and somewhat thickened, the fourth small, 

 subuliform; the tongue (Fi^. 37) narrow and short, cleft almost to the middle; 

 first joint of labial palpi longer than the second and third. 



Pronotum varies in form, most often narrower than elytra, sometimes 

 transverse, i.e. broader than long, sometimes as long as broad or longer. 

 Its more or less rounded or straight sides are in many species provided 

 with singly outstanding bristles; on the dorsum the impressions on prono- 

 tum, where such occur, oftenest more distinct in the o^ than in the o ; 

 posterior margin can in some instances be incurved inside corners so that 

 these thereby become more prominent (subg. Notothecta ) . Elytra very rarely 

 shorter than pronotum (subg. Jeostiba et al.), as a rule they are distinct- 

 ly longer than same. Their posterior margin inside the outer corners feeb- 

 ly or noi Incurved. 



In several subgenera abdomen is distinctly, however more or less, taper- 

 ing (subg. Goprothassa . Acrotona et al.); in the majority of the species it 

 is rather of equal breadth and only tapering at the hindmost Joints. Llost 

 often only the first three dorsal joints are transversally depressed at base, 

 but several species are also found in which the first four dorsal joints 

 at base are transversally grooved (subg, Bessobia , Plataraea , et al.), seldom
