the preaeding joint; while, in ciliatum, the 8th joint is seklom longer 

 (and often shorter) than the 7th. 



There is, however, a well-marked difference in the male puparia of 

 the two species. That of ciUatum has a well-dehned median area sur- 

 rounded by a raised border (the so-called "corona"), and there are 

 transverse ridges demarking an anterior and a posterior area. The male 

 puparium of zebrinum is without any indication of these subdivisions.

Adult female (fig\ 1, e) very strongly convex ; hemispherical or even sub- 

 globular, the sides overhanging the margin which is itself slightly out-turned ;

margins of anal cleft strongly upturned. In coloration it approaches some 

 forms of the early adult of L. capreae, having ivory-white bands upon a dark 

 particoloured ground (see fig. 3, a, b) which varies from ochreous-brown in 

 parts, through shades of castaneous to deep blackish brown. The white 

 bands, of which there are five or six, are interrupted on the median line, 

 except on the posterior abdominal segments, where they are continuous ; and 

 all but the first band are interrupted again on each side ; the first baud is the 

 broadest and has irregularly sinuous edges. The colour-patteru fades out and 

 becomes almost obliterated after the death of the insect. Surface smooth and
