PYGIDICRANA, 59 



then depressed and slender, elongate and gently ai'cuate, so as 

 to enclose an elliptical ai'ea ; in the apical quarter the branches 

 meet, are thickened and strongly toothed on the inner margin, 

 beyond which they are straight, contiguous, tapering, hooked and 

 crossed at the apex ; in the § the branches are long and straight, 

 unarmed, slender and contiguous, not depressed, almost cylin- 

 drical, the apices hooked and crossing.

The determination of the above specimens is not beyond 

 reproach. This species is common in Java, but it is doubtful 

 whether the true P. marmoricrura, of 8erville, occurs in India. 



One specimen in the British Museum is a fragment, with imma- 

 culate elytra ; another is complete, but is a female ; it is probably 

 a distinct species. 



Variation. — I have a specimen from the Tengger Mountains, in 

 Eastern Java, in which the elytra are of a uniform fuscous, owing 

 to the absence of the yellow discoidal spot, thus resembling P. cele- 

 bensis. The star-shaped spot on the bead varies considerably in 

 detail, but always resembles, more or less distinctly, a + + . 

 The dark bands on the pronotum sometimes unite posteriorly, thus 

 forming a dark V ; sometimes they are broken in the middle ; 

 they vary also in breadth. The black marbling of the outer 

 surface of the femora also varies considerably in detail but always 

 consists of two or three more or less broken blackish bands. 



There is a single specimen, probably referable to this species, in 

 the Hope Collection, Oxford, labelled " Thwaites, Ceylon." It is 

 common in Java, and is to be found in most collections. In the 

 " Cambridge Natural History," Sharp (I. c.) incorrectly calls it 

 P. marmoricauda, and figures it under the name P. hugeli, calling 

 it a "nondescript form," but giving it a nomen nudum, with no 

 description beyond a ])assing reference to general characters.
