in ictericus, their end slender and rather abruptly narrowed (this 

 character seems to be of some importance and pretty regular when 

 compared with the knobbed end of the same organ in ictericus). 



? (Dar-es-Salaam). The dorsal colour of head, thorax and abdo- 

 men is decidedly lighter than in the male from Salisbury, and not so 

 reddish, more greyish, with a shade of olivaceous. On thoracic 

 dorsum six brown points in two straight lines of three, almost equi- 

 distant from the median and humeral sutures ; the foremost of these 

 points very small. 



The dorsal colour occupies the anterior half of the metepimeron, 

 where two more dark points exist at the ventral third. Sides other- 

 wise yellowish, turning to greenish white on the ventral surface ; the

ventral metepimeral points sharp and deep black. Feet light yellowish, 

 distinct dark lines on the external surface of femora and also of first 

 tibiae. Abdomen dorsally like the thorax throughout ; very narrow 

 transverse darker lines near the distal ends of segments 2-6 ; a very 

 narrow mid-dorsal, longitudinal line on 8-10.

This single example very probably represents a distinct and 

 otherwise undescribed species. It is not to be expected that individual 

 colour varieties or stages of maturity in ocliraceus or ictericus should 

 culminate in the black- and-reddish colour scheme of this example. 



The superior appendages are not characteristic ; the inferior are 

 nearer to ictericii*, which species is more widely different in colours.
