So far as colouring is concerned this species approaches 

 Sp. formosus o( Porath ; but I infer from the description of 

 this last that the red dorsal bands are not continuous. More- 

 over, />rwos«,« is said to be " laive," and the anal valves are 

 compressed. In colouring again this species very much 

 resembles Sp. Utoralis ; but in Utoralis the whole head is 

 red and the dorsal spots are not continuous from segment to 

 segment. Porath mentions one specimen of Utoralis (his 

 tessellatus) as coming from Ca|)e Town and having a fuscous 

 band between the eyes. Tiiis example, I strongly suspect, is 

 in reality to be referred to this species.

 (PI. IX. figs. 10-10 c.) 



Colour olivaceo- fuscous, most of the segments adorned 

 posteriorly and laterally with an inferioriy narrowed orange- 

 yellow stripe, which runs along the hinder margin, beginning 

 on a level with the pore and extending halfway towards the 

 legs ; legs and antennai narrowly tcstaceo-annulate. 



Head convex, shining, smooth or only very finely striolate, 

 with two pores on each side of the labrum, with a longitudinal 

 mesially nearly obsolete sulcus. Eyes subcircular, consistino- 

 of about seven transverse rows of ocelli, separated by a space 

 equal to twice a diameter. Antenme short, shorter than the 

 head, segments subequal. 



First tergite smooth, its anterior edge lightly emarginate 

 on a level with the eye, the inferior angle wide, subacute, 

 with a faint anterior sulcus. The rest of the somites finely 

 striate laterally, the striaj falling far short of the pore, the 

 posterior portion smooth above, the anterior portion only very 

 finely striolate, the transverse sulcus visible only at the sides. 

 The jiores conspicuous, situated just behind the position of 

 the sulcus, above the middle of the side. Scubina large, 

 crescentic, extending from about the tenth to about the 

 fortieth segment, but very small towards the end of the body. 



Anal terqite smooth above and scarcely constricted, pro-
