250 CHELONARIUM DORSALE. 



sides and rounded tip, — Elytra rather finely and irregularly 

 punctured, having here and there the appearance of being 

 faintly rugose , and showing traces of faint costae ; the shoul- 

 ders are prominent in consequence of a shallow impression 

 along the base and a narrow deeper one along the basal por- 

 tion of the lateral margins. — The under surface is very 

 densely punctured. 



Hah. Java occid. — Captured by Mr. J. D. Pasteur, who 

 presented four specimens to the Leyden Museum. 



Together with these four specimens, and from the same 

 sources, I received two others which agree perfectly with 

 the described ones, but they are smaller (measuring 6 mm. 

 in length), the pro thorax is more narrowly rounded in 

 front and consequently of a narrower shape, and the 

 pubescence is denser and of a more yellow colour. Most 

 probably these two specimens are males, the four larger 

 ones females. 



If the above described species , which is very closely 

 allied to Ch. unifasciatum Reitt. from East Sumatra (Notes 

 Leyd. Mus. Vol. VIII, p. 219), did not possess the spot of 

 black pubescence on the middle of the back , I should have 

 meant to have Macleay's Ch. villosum before me, the short 

 description of which (see Notes Leyd. Mus. Vol. XI, p. 47) 

 being for the rest pretty well applicable to my insect.
