Longicornia Malayana. 507 



discal lines nearly obsolete ; scutellum dark brown, ob- 

 long-, triang-ular, the sides rounded ; elyti'a narrow, not 

 closely punctured, the lateral and sutural margins finely 

 bordered with dark brown, the apex of each drawn out 

 into a spinous point ; body beneath, legs, and antennae, 

 glossy brown.

X. viridi- vel cyaneo-metallica, apice elytrorum integro, 

 rotundato. 



Hah. — Sarawak, Malacca. 



Metallic green or blue ; prothorax marked with a 

 transverse impressed line anteriorly, the raised lines at 

 the sides giving place to an oblong depression, the disk 

 with closely set slightly corrugated lines of punctures ; 

 elytra closely punctured, less glossy than the prothorax, 

 the apices entire and somewhat rounded ; body beneath, 

 glossy golden -green ; legs and antennae dark blueish. 



Length 8 lines. 



In the above work this species was described as having 

 the apices of its elytra obliquely ti-uncate : this was owing- 

 to their being a little contracted on the sutural side in 

 my specimen, perhaps from its not being fully mature ; 

 the corrugated appearance of the prothorax and elytra 

 is very slight, and is scarcely perceptible, except in cer- 

 tain lights. 



CEEAMBYClNiE. 



" One of the most interesting groups of the Ceram- 

 bycidce," says M. Lacordaire, " but the most rebellious 

 as to classification, owing to the modifications to which 

 all the most important organs are subject." And to this 

 it may be added, that some of the species are liable to a 

 dea-radation of size and character which makes their 

 recognition difficult. The least exceptional characters of 

 the GermnhyGince seem to be — the membranous, deeply 

 bilobed labium ; a generally elongate projecting head,* 



* The head is often furuished iu front, above the clypeus, by a sort of 

 'scutcheon or " plaque " {plaque frontale, Lacord.); it is formed by a more or 

 less deeply impressed line surrounding a transversely oval, or nearly oval, 

 space.
