First tei'fjite smootli, shiiiiiiii'. Its sides cvonl}' rouuded. 

 MaifriiiHl .sulcus very short, exteiidiuii' t'loiii tlic Nnver level of 

 the eye to the middle ol tlit- curve of the sides. 



Scobiuas t'roiu about (he t'oiiiteeut h segment to about tiie 

 thirtieth. The distance between the dimples is equal to 

 almost four times the breadth of one oF them. Dimple oval 

 (PI. xvii., tig-. 56), distinct from the antei'ior ni!ii'<iin of the 

 zoiiite, thou<jh cTose to it. The posteiioi' field is ti-iang'ular, 

 acute, dull, but not sti'iate. 



The integuments (PI. xvii., tig. 57) are strewn with minute, 

 longitudinal, widely spread stria^. The anterior concealed 

 part of the prozonite, although not completely smooth, shows no 

 distinct concentric sulci. The posterior part is adorned with 

 arched oblique strife ; these gi'ow gradually more perpendicular 

 above the pores and turn into a transverse, dorsal, moderately 

 impressed sulcus, as distant from the anterior smooth part as 

 from the metazonite ; this sulcus is interrupted dorsally on the 

 segments two, three and foui', and on a widei- space on the 

 second than on the other segments. Below the pores, the 

 strife assume a more and more longitudinal direction and 

 gradually encroach on the metazonite. Immediately above 

 the pore, the segment is crossed by a longitudinal sulcus which 

 is situate on a level with the poi'e, whei-e it meets the sutiiral 

 sulci ; on the metazonite, its course is directed diagonally up- 

 wai'ds. The sutural sulcus is obsolete dorsally, faintly 

 im})ressed laterally, less marked than the sulcus of the 

 prozonite. 



Posterior margin of last segment angularly produced, the 

 apex leaving uncovered the ujiper angles of the valves. The 

 latter are moderately prominent, slightly compressed and 

 without any trace of marginal sulcus. Anal sternite triangu- 

 lar; its base is broad, about equal to twice the length of the 

 sternite. Sterna of other segments transversely sulcate, the 

 sulci thin and numeroiis. Stigmata small. 



Legs short; from the fourth pair backwards, all the joints 

 except the last are provided with but one ventral bristle. 



Male : — Tai-si jiadded and coxa^ of third, fourth and fifth pair 

 produced as in i). laiiceolatnK; yet pads and piocesses are i-ather 

 less developed. Femora of second pair flattened interally, 

 gibbons posterioily. Penis small, conical.
