edges there are several small black punctures, also similar 

 markings on the posterior margin of the shield. The 

 latter is furnished with four pairs of long yellowish hairs, 

 shaded at the base, which arise from small darkish brown 

 tubercles arranged as follows: four bordering the 

 anterior margin, one placed each side, immediately 

 behind the median transverse groove near the lateral 

 margin, and one each side of the median longitudinal 

 pale line, near the posterior edge of the shield. 



On each of the second, third, and fourth segments there 

 are two pairs of prominent fleshy spikes two median and 

 two lateral. On the second and third segments the 

 median pair situated each side of the dorsal line are the 

 largest, and dark in colour; the lateral ones are pale and 

 slightly shorter. Both pairs on the fourth segments are 

 pale. 



These fleshy spikes are piliferous, bearing large 

 numbers of short fine hairs, which are dark on the dark- 

 coloured spikes, and pale on the others. From the apex 

 of each spike there springs a very long pale hair. 



The base of each of these piliferous prominences is 

 surrounded by a patch of bright orange colour. On the 

 second, third and fourth segments, between the median 

 spikes and immediately each side of the dorsal line, there is 

 a small brownish tubercle, from which arises a short fine 

 hair, dark at the base, pale at the tip. There is also a 

 similar tubercle between the median and lateral spikes, 

 which is surrounded by a blackish area. There are 

 several short hairs near the base of the lateral spikes on 

 .segments three and four. 



On each of the segments from five to ten there are two 

 median and two lateral piliferous fleshy spikes, but they 

 are less conspicuous than those on the anterior part of 

 the body. Each is surrounded at the base by an orange- 

 coloured area, which is more marked in the case of the 

 lateral than of the median spikes; around the latter it is 

 frequently obscure or absent, especially posteriorly. The 

 spikes themselves on this part of the body are sometimes 

 pale orange in colour. On the fifth and sixth segments 

 there are four prominent blackish or dark brown spots; 

 on the posterior edge of these there is a small tubercle
