longer than broad, pointed at the apex ; lobes of the metasternura 

 narrow, elongate, parallel and pointed at the apex itself. Abdo- 

 men on the back and sides black, with a light shot-bronze 

 shading ; on both sides of the middle line there is a row of large 

 tubercular folds. On the first dorsal segment between the first 

 and the third small black tubercles there is a small yellow spot 

 which surrounds the second tubercle with a radius equal to the 

 distance between the first and second segment. On the second 

 segment the spot occupies a space of the same width, but extend- 

 ing from the anterior to the posterior margin of the segment ; 

 beginning with the third segment, and continuing as far as the 

 eighth ; between each first and second and second and third 

 small tubercle there is a small yellow spot not fused with the 

 neighbouring spot of the same segment. On the ninth segment 

 the spots coalesce ; on the tenth the tubercles disappear, and 

 there remains a scarcely perceptible little yellowish spot. The 

 under side of the belly is bright greyish yellow, the first and 

 second ventral segments with a brown marking. 



The subgenital lamina of the female is rounded, with a fairly 

 deep emargination on the apex, without teeth (thus differing 

 from C. pancici, Brauner) ; the cerci (female) are short, conical, 

 and pointed. 



The male does not differ from the female in colour, and the 

 cerci are cylindrical, without teeth on the inner side. Subgenital 

 lamina slightly raised, with two keels.

MACEOCENTKIDiE. 



The species of this small family are very familiar insects of 

 fair size and gregarious habits, as many as a hundred occa- 

 sionally emerging from a single large lepidopterous larva. The 

 pale species of Zele strongly resembles small Panisci or large 

 Meteori, from both of which the sessile abdomen and neuration 

 will at once distinguish them ; while Macrocentrus marginator 

 appears superficially allied with the Lissonotid Pimplinae. The 

 two European genera are known by : — 



Occiput not bordered ; first segment not longer than second 



Macrocentrus. 

 Occiput bordered ; first segment much longer than second Zele.
