Analysis of the subfamilies of Polyzoniidce. 



* Gnathochilarium represented by an actite triangular plate ; dorsal plates not sul- 



cate nor covered with short stiff hairs; lateral carinse not well developed. 



Polyzoniin^e. — A. 



* *Gnathochilarium subsimilar to that of the Julidm) dorsal plates medianly and 



transversely sulcate, covered with numerous short hairs ; lateral carinse well 

 developed Platydesmin^e. — B.

Body wide, depressed, elongate-oblong; convex above, slightly con- 

 cave beneath ; not pilose. Head distinctly rostrate, partly concealed 

 under the first dorsal plate. Antennae subclavate, bases approximate, 

 articles subequal. Ocelli present, 2-4, arranged in two diverging 

 series between the bases of antennae. Mandibles small, triangular. 

 Gnathochilarium much degenerated; stipes apparently deeply bifid, 

 acuminate; lingual lobes well developed; promentum small, ovate; 

 mentum, hypostoma and cardo not developed. Dorsal plates smooth, 

 not sulcate or tuberculate, first arcuate, advanced forward to the base
