138 Longicornia Malayana. 



dato, integro ; articiilo tertio paulo longiore; quarto breviore; 

 caeteris ad undecimum brevissimis ; ultimo paulo praecedenti 

 longiore. Prothorax quadratus, lateraliter leviter rolundatus. 

 Elytra oblonga, subangusta. Pedes Iseves ; tibicB anticae cur- 

 vatae ; tarsi baud dilatati. Pro- et meso-sterna depressa. Ab- 

 domen segmentis subaequalibus. 



This remarkable little genus with its twelve-jointed antennae, 

 peculiar scape, and depressed pro- and meso-sterna, would almost 

 appear to be out of place in this sub-family ; perhaps, indeed, it 

 might have been better ranged with the ApomecyniiKV. I have 

 only seen a single example, apparently a male, which, according 

 to Mr. Wallace's note, was found " under fallen timber." 



Diexia punctigera. (PI, VII. fig. 1.) 



D. fusca, vage hirsuta, supra fortiter punctata, lineis griseo- 

 pubescentibus ornata. 



S^ab. — Singapore, 



Dark brown, somewhat glossy, with scattered erect hairs, other- 

 wise nearly glabrous, except the head and certain greyish pubes- 

 cent lines on tlie prothorax and elytra; the upper surface strongly 

 and rather remotely punctured ; head covered with shaggy patches 

 of hair in front, behind the eyes a white mark, which corresponds 

 with a stripe along the side of tlie prothorax and over the slioulder 

 to the middle of the elytra, where it joins a short transverse line, 

 the apex of each elytron bordered with a white line on its sutural 

 margin, which is connected behind with a transverse one; body 

 beneath pubescent, whitish ; legs covered with long whitish hairs, 

 the tarsi black ; antennae hairy, pale greyish or white, the first, 

 second, fifth and last two joints, and the tips of the third and 

 fourth, black. 



Length 3 lines. 



Apomecynin^. 



Many of the genera of this sub-family, as it is here limited, 

 have been, hitherto, widely dispersed in systematic works; but, 

 taking their general characteristics into consideration, we get a 

 long series of forms, many of them very remarkable, but which, 

 when seen together, seem to be sufficiently connected to justify 

 their juxtaposition. 



The body of these insects is generally elongate, and either 

 cylindrical, fusiform or irregular, that is, with the elytra broader 

 than the prothorax ; at the same time the legs are below the usual
