Ml. S. ami Dr. L. F. Iliist on 



postoro-lateral margin of the pseudoscutum (see Colour). A 

 pair of cliaracteristic oblique impressions, partly formed of 

 enlarged punctures, are present posteriorly, one on each side 

 of the scutum ; their shape resembles somewhat that of a 

 comma, the broad end being situated close to the margin 

 (near to the anteriormost festoon and almost touching the 

 upper end of the stigma), the narrowed end pointing inwards 

 and coimected by a dark and narrow line (and sometimes by 

 an ill-defined depression also) with the posterior margin of 

 the pseudoscutum. Postero-median groove represented by a 

 smooth dark line. Marginal grooves are not present. Fes- 

 toons short and fairly well defined. Eyes small, flat, and 

 pale in colour (fig. 3).

Ventral surface finely wrinkled. Stigmata long, narrow, 

 and 8lia})ed like a comma. 



Rostrum short ; its base rectangular, the dorsal surface 

 being furnished with a number of minute punctures. Hypo- 

 stonie with three files of teeth on each side. 



Legs short. Coxa o£ first leg with two short and incon- 

 spicuous spurs ; coxce of second and third unarmed (or with 

 a single very short spur) ; coxa of fourth with a single very 

 short spur. Tarsus of fourth rather gradually narrowed. 



Colour. — A pseudoscutum, which is light brown in colour 

 in dried specimens and copper-coloured when immersed in 

 spirit, is present, and the central part enclosed by the cervical 

 grooves is sometimes darker than the sides ; its posterior 

 margin is delimited by a pale transverse line. The rest of 

 the suiface of the scutum is drab (in spirit copper-coloured).
