median blotches on the abdomen. It is by these characters mainly 

 that Kellogg separates his confidens from tricolor. In confidcns, 

 while there are no blotches on the abdominal tergites, such marks 

 appear on the sternites. These may not show on normally pre- 

 served opaque examples but when specimens have been macerated 

 or dried the marks on the under side of the abdomen shine through. 

 The above material from Sooty Albatross is in a bad state of 

 preservation and agrees exactly with Piaget's illustration of tricolor, 

 but a little care in focusing shows that the blotches seen are on the 

 sternites. 



Piaget's types taken from Museum skins were probably in a 

 similar state and a little rough handling would account for the 

 occiput being " nu." On the chief remaining difference between 

 tricolor and confident length one cannot venture much. We 

 have not sufficiently good material of the species before us on 

 which to base an opinion.

At first we had referred these examples to L. angusticeps, Piaget 

 (Les P6diculines, p. 306, pi. xxv. fig. 4, 1880), but on reconsidering 

 them, we find that from their dimensions they agree better with 

 L. diversus, Kellogg. How the two forms are related it is hard 

 to say. As Kellogg points out, there are conspicuous differences 

 in the measurements, but we should not care to lay great stress 

 on the additional features adduced. Kellogg states that in a 3 

 diversus the posterior border of the signature is angularly concave 

 not straight as in angusticeps. One of the above $ $ shows this 

 outline, in the other the line is nearly convex. In diversus there 

 are two short temporal hairs which appear also in the S.A. Museum 

 specimens, but in some cases one or other is broken off. Piaget 

 describes angusticeps as having one temporal hair, but the example 

 he described may not have been perfect. In diversus the inturned 

 antennal bands are continuous with the bands bordering the oral 

 fossa. Now it is true that Piaget says of angusticeps, " Les 

 antennals tres prononcees s'arretant au clypeus," but he adds 

 immediately, "Les deux bandes internes ne a'arretent pas a la
