258 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [May 8, 

 ASTATHES SPLENDIDA. 



Cerambyx splendidus, Fabrieius, Eut. Syst. t. i. pt. 2. p. 263. 

 This is also an Indian species. 



Astathes terminata, Pascoe, Trans. Eut. Soc. ser. 2. iv. p. 109. 



Varies in the extent and depth of the yellow at the apex of the 

 elytra ; the abdomen is also frequently more yellowish than brown. 

 In some examples a sort of areola may be noticed round the punc- 

 tures on the posterior part of the elytra, a peculiarity which is very 

 remarkable in A. perplexa, Newm. 



Astathes nigricornis, J.Thomson, Syst. Ceramb. p. 560. 



An entirely fulvous species, with black antenna?. A marked cal- 

 losity on each side of the prothorax will distinguish it from an un- 

 described species from Morty with a similar coloration. A fourth 

 species, with the antennae imperfect, is in the collection. It has a 

 yellow head, with a dusky patch behind each eye ; otherwise it ap- 

 proaches very closely to an undescribed species from Singapore. 

 The distribution of the two colours, blue and yellow, and the inten- 

 sity of the black, are too variable in this genus to carry much weight 

 in the determination of the species. The Astatheince are remarkable 

 for the peculiar modification of the metasternum : this is prolonged 

 anteriorly between the intermediate coxae, so as to completely overlap 

 that part of the mesosternum lying between them.

Of this extensive and very difficult genus I have about twelve 

 species or qnasi-syecies, which may be probably referable to Olivier's 

 Saperda elegans. They are all of the richest metallic blue, with 

 snowy-white spots and stripes, varying in length from 8 lines to \\ 

 inch. The spots and stripes are without doubt very uncertain cha- 

 racters, and the minor differences, for there are no others, are very 

 unsatisfactory on paper. Nevertheless it may be perhaps necessary 

 to name some of the extreme forms. Mr. Lamb's specimens have 

 yellow legs ; but this scarcely seems of specific importance. Glenea 

 delia, J. Thorns., from the character " humeris fere nullis," is doubt- 

 less distinct. Another Glenea in the collection has the elytra ra- 

 pidly narrowing from the shoulders, and rather suddenly rounded 

 near the apex, which is much narrower and at the same time more
