iis in Batodesmus. Metatergites coarsely tubercular, the cauda 

 tubercular. Legs rather long, granular. Gonopods of male 

 deeply bifid into a broad anterior plate and a posterior branch 

 lying against the former, the posterior branch, through which 

 the seminiferous tube runs, with a spur toward its base. 



Genotype, C. hirrutcllus, sp. nov. 



In the concealed or absent repugnatorial pores suggesting 

 Batodesmus, but readily distinguished from that genus in 

 lacking spines on the sterna, in the tubercles of tergites, etc. 



Cormodesmus hirrutellus, sp. nov. 

 PI. 21, Figs. 145-148; PI. 22, Fig. 149 



The types at present are dark brown, inclusive of legs and 

 antennae, excepting that the prozonites may be paler, especially 

 below, the color due mostly to adherent material and growths, 

 beneath which the color is fulvous. 



Surface of head granular. A series of longitudinal striae 

 across base of vertex. Vertigial sulcus and furrow distinct 

 to level of antennae. Antennal sockets separated by not more 

 than the diameter of the latter. Antennae short, when 

 extended straight back not cjuite attaining caudal edge of col- 

 lum. (PI. 21, Fig. 146.) 



CoUum with anterior and lateral margins together forming 

 an evenly convex line, excepting for a tubercular projection 

 at anterolateral corner below ; the posterior corners more nar- 

 rowly rounded. Posterior margin weakly convex excepting 

 at ends, where more strongly convex. On dorsal surface a 

 row of tuljercles entirely across anterior border; at each end 

 the plate presents an elevation formed by tubercles of the 

 anterior series and two caudad of it, the latter series not 

 extending across middle region of plate. On the median part
