500 Longicornia Malayana. 



disco inaequali, aliquando carinula lateraliter utrin- 

 que marginato. Elytra parallela; depressa. Pedes 

 validi ; femora inci'assata, compressa ; tihice com- 

 pressge, arcuatae. Co.ire intermediae liaud contigu^e. 

 Prosteraum angustatum ; onesosternum simplex. Ab- 

 domen molle. 



The characters of the antennge are less marked in the 

 females, and in some species the posterior legs appear to 

 be considerably shorter. The second joint of the an- 

 tennge, which is unsually short, appears to me to be con- 

 nate, or nearly so, to the third. Two species of this 

 genus are known from Australia, and several from 

 Africa.

 glossy chalybeate blue, the middle of the disk fulvous, 

 space between the two lateral raised lines on the disk 

 heart-shaped ; scutellum triangular, smooth ; elytra re- 

 motely punctured, the whole of the sides chalybeate 

 blue, the rest fulvous, the apex rounded, unarmed ; 

 body beneath, fulvous, the postpectus pubescent ; abdo- 

 men smooth, glossy ; legs reddish-fulvous, the tibiee, 

 except at their apices, blackish ; antennae black.

This fine species differs, inter alia, from the type 

 X. gJohosa, 01., in the larger prothorax, broader space 

 between the lines on the disk, the absence of the median 

 stripe on the elytra, and their sparse punctuation. 



Xystrocera apicuJata. 



X. testacea, marginibus elytrorum, pedibus, et corpore 

 infra piceo-fuscis, illis apice acuminato-spinosis.
