the base and less so near the apex, and 'with yellow or orange 

 markings ; it is at least live times as long as its broadest part, 

 which is on the second segment, after which it gradually narrows 

 to the end of the third segment and then very slightly widens to 

 the genital knob. The extreme sides of the basal segment are 

 yellow up to the entire and rather broad yellow band which 

 crosses the second segment about its middle ; the third segment 

 has also an entire yellow or orange band which crosses the segment 

 about its middle, but which is much broader than the one on the 

 second segment ; the fourth segment is brownish-orange with a 

 black spot on the middle of the upper margin, which spot extends 

 down vertically for about one third of the segment, and laterally, 

 rather broadly to the side maigins ; the lower margin of the 

 fourth segment has a similar, but much larger spot which also 

 extends laterally to the side margins and up a dorsal line for 

 about half the segment; however, all the markings on this segment 

 are usually rather vague and variable in size and shape ; the fifth 

 segment has a black dorsal line on the basal three-quarters, with 

 a pair of black spots outside the end of this line, and, with a 

 black (sometimes vague) elongate spot on each side of the basal 

 margin i after this comes the short and small orange sixth segment 

 followed by a large shining orange cap, with two round black 

 spots over the ball-like genitalia, near the base of which are two 

 brown spots. Very often the black and orange markings of the 

 abdomen run together, thus rendering the orange more reddish and 

 leaving the black markings less defined, especially on the third and 

 fourth segments. Pubescence on the abdomen rather short and 

 mainly following the ground colour, except on the two basal 

 segments where it is long and pale. Venter with rather indistinct 

 alternate bands of yellow and brownish-black ; its pubescence is 

 mainly pale. Hypopygium extremely large, prominent, nearly bare 

 and consisting of a large globular mass which is mostly under the 

 fifth segment ; at the end of which is a pair of broad lamellae with 

 shagreened ends., which bear tufts of long pale hairs; still further 

 concealed are numerous processes with which no one is perfectly 

 acquainted. 



Legs almost entirely orange, very simple with short 

 inconspicuous pubescence, which is mostly pale on the front legs, 

 and blackish on the hind legs ; middle femora always with a 

 distinct, more or less black ciliation on the ventral surface ; hind 

 coxae with long pale yellow hairs; on nearly all the rest of the 

 hind legs, except for the trochanters which are nearly bare, there 

 are small black bristles which are much denser and crowded on the 

 tibiae. The tarsi are thin and rather darkened on the third, fourth
