General colour brown, often very light. A distinct longi- 

 tudinal median dorsal black line which is commonly interrupted. 

 The usual series of black spots over the repugnatorial glands, but 

 each spot embracing one or more light areas, and so often incon- 

 spicuous. A dark transverse line across dorsum and connecting 

 the two lateral spots of each segment. Also below the spots a 

 dark line or band is more or less developed ; this band is areolated 

 with light spots and is often inconspicuous or scarcely evident. A 

 broad black band across anterior border of first plate, anal scutum 

 often blackish. Eyes black. Antennae dusky brown to black, 

 the distal article commonly pale. A solid black band between 

 antenna? with a light spot in each end near antennae. Vertex 

 marked with close network of coarse dark lines. Lower part of 

 head dusky, more or less areolated with light dots, a larger light 

 area below each antennae and along labial margin, above which 

 and ectad of lateral light areas there is commonly a dark band. 



Sulcus of vertex fine, ending near upper level of eyes. A 

 deep setigerous foveola on each side of anterior end of the sulcus, 

 the female sometimes more or less extended laterad. 



Eyes large, subtriangular, but the sides convex. Ocelli 

 mostly between 42 and 52 in 7 to 9 transverse series, e.g.: 



7, 7, 7, 6, 6, 5, 3, 1; 9, 9, 8, 7, 6, 5, 3, 1. 



First dorsal plate with lateral border rounded, no*t at all 

 angularly produced. Distinctly but not strongly margined. Two 

 striae across lateral ends and a number of less deep short ones 

 above these across caudal border. 



Second segment deeply striate ventrally and over lower 

 portion of sides, the striae well separated above, but closer together
