SUMATRAN COLEOPTERA. 245 



shows a few irregularly placed hair-bearing granules , and 

 in the centre a few wrinkles. The lateral spines are placed 

 about the middle and obliquely directed upwards; they are 

 long, rather slender and acute and glossy black. The scu- 

 tellum is very broadly rounded posteriorly. 



The elytra are gradually narrowed towards the end; 

 they are provided at the base, especially on the promi- 

 nent and somewhat compressed shoulders, with numerous 

 glossy granules which are gradually replaced by deeply 

 impressed punctures arranged in longitudinal rows and 

 becoming less and less distinct towards the end. At the 

 base , between the shoulders and the scutellum , a feeble 

 crest is present which is beset with glossy granules. The 

 apices are narrowly truncate with very blunt angles. 



The bare dots on the under surface and legs are im- 

 punctate. The apical ventral segment is longer than the 

 preceding one , and broadly truncated posteriorly with roun- 

 ded lateral angles. 



10. Thysia tricincta Casteln. — A single specimen. 



To this lot Mr. Pasteur joined some Butterflies ') from 

 Padang Sidempoean (situated at an elevation of about 1000 

 feet above the level of the sea) and three insects captured 

 (likewise by himself) at the Upper Bila , during a journey 

 from Padang Sidempoean to Deli. 



One of these specimens is identical with the larva de- 

 scribed and figured in 1831 by Perty in his »Observatio- 

 nes nonnullae in Coleoptera Indiae orientalis" (p. 43, fig. 

 8 and 9), and which is said to be that of an Episcapha- 

 species. It was found by Mr. Pasteur in dense forest , slowly 

 walking on a fallen tree , and has , according to its cap- 

 tor, after death undergone no change whatever, neither in 

 form nor coloration. 



The second is a specimen of Lanternfly (Hotinus pyro- 

 rhinus Donov.). Mr. Pasteur writes me that he had kept

 Fabr., Papilio Polytes Linn., and Papilio leucothoe Westw.
