Longicornia Malayana. 59 



Caput angustum, antice transversum, tubeiibus antenniferis basi 

 distantibus. Oculi fere divisi. Antenna corpora longiores, 

 setaceae, ciliatse ; scapo oblongo-ovato, articulo quarto tertio 

 longiore, caeteris brevioribus et subaequalibus, ultimo apice 

 curvato. Prolhorax latus, subtransversus, rugosus, disco 

 depresso, dentibus duobus validis. Elytra oblongo-ovata, 

 convexa, regularia, apice integra. Pedes mediocres, antici 

 maribus elongati et femora antica crassiora. Pro- et me&o- 

 sterna elevata, faciebus oppositis. 

 A broader and more robust form than Niphona, the prothorax 

 more convex and even, the sterna more pioduced, the fore-legs 

 of the males elongate, and their femora larger than those of the 

 intermediate and posterior legs. From Axiothea it differs in the 

 unbroken surface of the prothorax and elytra. The species, and 

 even individuals, vary greatly in size, and owing to the mono- 

 tonous repetitions of nearly the same sombre and indistinct colours, 

 are difficult to determine as well as to describe.
