376 Loiigicornia Malayana. 



Glenea Thomsonl (PI. XVII. fig. 1.) 



G. cyaneo-chalybeata, cceruleo-varia ; apicibus elytrorum in 

 medio spinosis (^,$). 



Hab. — Batchian. 



Dark chalybeate-blue ; head with a few small scattered punc- 

 tures in front and on the vertex, margin beneath the lower part 

 of the eye pale blue ; prothorax nearly impunctate, the sides 

 slightly rounded, a large semicircular band extending from the 

 base to the sides, where it is continuous with the band beneath 

 the eye, whitish or pale blue ; scutellum subscutiform, whitish or 

 pale blue, except at the two anterior angles ; elytra broad at the 

 base, gradually narrowing posteriorly, the apex of each termina- 

 ting in a single median spine, a large, somewhat lozenge-shaped 

 ring in the centre, but extending to the external margins, either 

 ochraceousor pale blue, behind the ring a pale blue oblique stripe 

 extending from the suture outwards and downwards ; body be- 

 neath with pale blueish patches, especially at the sides of the ab- 

 dominal segments, the lateral patches in one specimen ochraceous ; 

 antennae and legs dark blue, with a slight pale blueish pubes- 

 cence. 



Length 9 (^)-_12 ($) lines. 



Very distinct from all other species of this genus on account of 

 the single median spine terminating each of the elytra. I have 

 only a male and female, the latter on account of its size and the 

 clear ochraceous ring on the elytra surpassing the former in 

 beauty, and ranking perhaps as one of the most elegant of the 

 Longicorns. 1 have much pleasure in dedicating it to M. James 

 Thomson. 



Glenea heptagona.
