Longicornia Malayana. 44-5 



its being within Uie possibilities of variation from the preceding, 

 with which in the style of coloration of the elytra it so nearly 

 agrees. 



Arsysia tessellala. 



A. cinerea, capite prothoraceque nigro-vittatis ; elytris nigro- 

 reticulatis, apicibus extus valde mucronatis. 



Hab. — Ceram. 



Light ashy ; head with three glabrous black stripes, one on the 

 vertex and one behind each eye, corresponding with three of a 

 similar character on the prothorax, but which do not extend quite 

 to its base, the intervals with small scattered punctures; scutellum 

 slightly transverse, with a glabrous central line; elytra with rather 

 small scattered punctures extending nearly to the apex, the ashy 

 colour divided into several large patches by irregular black lines, 

 the apices with the external angle strongly mucronate ; body 

 beneath and legs light ashy. 



Length 5| lines. 



My unique specimen of this very distinct species wants the 

 greater part of the antennae, but what there is shows that they 

 were thickly covered with ashy hairs, with the apex of the third 

 joint black. 



Hestima. 

 Caput verticale, antice transversum, tuberibus antenniferis 

 validis, distantibus. Ocul'i grosse granulati, profunde emar- 

 ginati. Antennm setaceae, corpore longiores ; scapo sub- 

 clavato ; articulo tertio scapo longiore ; quarto fere tertio 

 aequali ; sequentibus brevioribus et gradatim decrescentibus. 

 Prothorax fere aequalis, lateraliter rotundatus et inermis, 

 margine basali sulcato. Elytra elongata vel oblongo-ovata, 

 apicibus oblique truncatis. Pedes mediocres, paulo cres- 

 centes ; femora fusiformia; tibi(S intermediae valde emar- 

 ginatae ; tarsi fere aequales. Propectus breve. Prosternum 

 postice productum, in incisura trjangulari mesosterni re- 

 ceptum. 

 This last character, although general among the more typical 

 Tmesisternmce — i. e., those with the head porrect — is nearly pe- 

 culiar to this genus in that part of the sub-family which possesses 

 the usual vertical head of the Lamiidce. A slight emargination of. 

 the mesosternum is found in Arsysia, very different, however, from 

 the triangular notch of Hestima.
