12B KHCORDS OF THE AfSTHALlAN MCSEl'M. 



Anterior zone of the prozonite partly covered with irreg-alar 

 transverse striae ; posterior zone strewn witli extremely fine, 

 somewhat elongate punctures : metazonite still less distinctly 

 sculptured, yet bearing along the suture some more strongly 

 marked punctures ; a few deep punctui'es also stand in fi'ont 

 of the suture. Sutural sulcus almost obsolete dorsally, distinct 

 elsewhere, crossed, on a level with the pore, by a longitudinal 

 sulcus more shallow on the pro- than on the metazonite. 

 Pores stai'ting on tlie sixth segment, small, located high up in 

 the sides, near the suture and beh)W the above-mentioned 

 longitudinal sulcus. The usual oblique and longitudinal sulci 

 are only to be seen low down in the sides and above the legs, 

 lower still in the postei-ior half than in the anterior half of the 

 liody. 



Posterior margin of last segment produced into a very short 

 conic, acute process just reaching over the superioi- angles of 

 the valves. The latter are not prominent, modei-ately globular, 

 scarcelv depressed, with rounded margins and without any 

 trace of pre-mai-ginal sulcus. Anal sternite triangular, its 

 length about two fifths of its breadth at the base : sides 

 straight, apex cut at a right angle. Sternites of the <ither seg- 

 ments transversely sulcate. Stigmata small. 



FiCgs short (about ;^.50 ni m). i»iit with one distal l)fistle 

 below on the five pi'oxiuial joints. 



Male : — Anterior pair of legs thickened but without tarsjil 

 pads. Second joint of the second pair showing inwardlv a 

 Battened sniface giving i-ise to a sharj) posterior edge. Coxap 

 of the third, fourth and fifth pair tipped with a hnig, but 

 gradually decreasing digitiform process (PI. xvi., fig. 89), the 

 end of which is more or less rounded ; besides, the second joint 

 of the same legs is inoi-e or less warted below. Venti'al 

 margin of the seventh segment produced into a transverse 

 thickened edge, notched mesiMlly in frtnit. 



Copuiatory apj)endages : — .Vnterior gonopods (PI. .xvi.. tigs. 

 40, 41) ; basal part of the venti'al plate I'onghly hexagonal ; 

 proximal margin sti-aight, angles cut off diagonaly, anterior- 

 lateral sides sti-aight. The distal pait is a linguiform process, 

 lono-er than the base. siTT-aduiillv narrowed, with straiirht sides
