Fig. 2. Oregma muiri n. sp., 



head and prothorax of apterous female (dorsal view). 



e = eye; gl = glands; /r Â = frontal horns. 



Antennae short, only ^/^ the length of the body, five- 

 jointed ; relative lengths of the last joints about as: 21,14,22. 



Rostrum reaching to the 2"*^ pair of coxae. 



Siphunculi reduced to large pores. Cauda broad, wartlike, 

 slightly constricted at the base. Anal plate bilobate ; rudimen- 

 tary gonapophyses 2. 



Legs moderately well developed, furnished with a few 

 fairly long hairs. 



Waxglands well developed, of the common ,ymsu/arts-type" , 

 viz grouped along the margins of head, thorax and the 

 abd. segments i + 8 in single, longitudinal rows. Glands 

 moderately large, oblong, close together, their longest sides 

 parallel or only slightly converging ; the outmost glands of 

 each group often are more or less semi-circular in shape. 

 The waxglands are largest on the abd. segments 4, 5, 6, 

 becoming smaller towards each side, being especially much 

 smaller on thorax and head. The two groups on abd. segment 8 

 are placed on the lateral hindmargin of the segment, nearly 

 touching each other in the middle of the segment and only 

 separated by a space of one waxgland's breadth. Each 

 group of glands is accompanied by one long hair. 



Arrangement and number of glands generally is as follows : 



kead 4 — 6, protliorax 3 — 5, mesothorax 4 — 5, metathorax
