Abdomen of 9 segments, elongate -oval., with strong lateral bands to 

 first seven segments; transverse bands of 1st segment meeting in the 

 middle line ; of 8th segment continuous ; of segments 2-7 short extending 

 irom two-fifths to one-quarter across width of abdomen, and leaving a 

 large clean central area ; segment 9 very short, and slightly bifid with 

 small dark oval blotch in either lobe ; each segment, except the last with 

 a series of pustulated hairs along the hind margins of the transverse bands 

 in the anterior segments embraced in serrations of the bands themselves' 

 but becoming removed from the bands as we proceed posteriorly, so that 

 the hind margin of the band of segment 6 is only slightly serrated while 

 that of segment 7 is entire ; posterior end of lateral band of segment 2 

 forms a strong spinous projection, and there is a 

 similar but less prominent projection in segment 3 ; 

 1 to 3 hairs in posterior angles of segments 3 to 

 8 ; segment 9 with a prickle on either lobe. Genital 

 blotch prominent, and best understood by reference 

 to the figure. 



Length, 2-42 mm. ; breadth, 1-05 mm. ; head

Description of Male. — Generally smaller and 



darker than female, with golden-brown head and

markings, except that the two small markings in 



the curve of the inner antennal band are absent ; 



marginal bands of prothorax stronger ; abdomen 



pyriform, widest at 3rd and 4th segments, thence 



abruptly tapering to a longer 9th segment, with 



obtusely rounded angles, and an almost flat hind 



margin ; segments 2 to 7 with very strong lateral 



bands of blackish brown ; posterior angles of 



segment 1 rounded under segment 2; of segments 



2-5 strongly projecting, segment 3 especially so, 



with a strong spine ; chitinous parts of segment 9 



standing out dorsally as a flattened semicircular 



prominence, the lateral borders of which are inside 



the actual margin of the segment ; with 2 strong 



lateral blotches, connected by a narrow line alono- 



the hind margin, and much broken by large 



pustules, bearing hairs, about 20 in all ; transverse 



bands of segment 1 meeting mesially, and of the 



remaining segments separated by a narrow median 



line ; hind margin of segments 2 to 6 bordered by 



a narrow dark line, hardly interrupted mesially ; 



-.•nitalia complex, generally resembling those of 



P. wallacei, but differing in being partly obscured on the ventral side by a 



striated chitinous supporting plate and in the narrower chitinous bands ' 



Length, 1-98 mm. ; breadth, 0-91 mm. Head: Length, 0-67 mm ■
