Longicornia Malayana. 23 



sharply ridged at the base, with two or three slighter ridges on 

 the same line, the side bent down but not angulated except at the 

 shoulder, the margins towards the apex fringed with stiff hairs ; 

 body beneath brown, with scattered greyish hairs ; legs with 

 longish grey hairs ; antennae luteous brown, with greyish hairs. 

 Length 3| lines. 



Phyxium ignarum. 



P. grisescente-fuscum ; prothorace toto griseo-pubescente ; an- 

 tennis brunneis, articulorum apicem versus gradatim infuscalis. 



//g6.— Mysol. 



Much narrower in proportion than the last, dark reddish-brown 

 with a very thin greyish pile. Head small, considerably narrower 

 than the prothorax, which is nearly twice as broad as long, both 

 closely, and the latter also coarsely punctured, with the greyish 

 pile pretty equally distributed over the surface ; elytra scarcely 

 dilated posteriorly, as in the two preceding species, with very 

 coarse punctures arranged in irregular rows, the ridge at the base 

 very slightly elevated and extending to about the middle of the 

 elytron, the side scarcely angulated, but the interval between the 

 two rows of punctures at that part somewhat raised; body beneath 

 pitchy-brown, with a scattered pile principally on the breast; legs 

 reddish-brown, covered with a greyish pile; antennae pale reddish- 

 brown, the apex of the third joint and all the succeeding joints 

 becoming more and more tinted with dark brown.

ACALOLEPTA. 



Jcalolepta, Pascoe, Trans. Ent. Soc, ser. 2, iv. 247. 



Caput exsertum, antice quadratura. Ocnli parvi, in vertice non 



visi. Antennce nudae, longissimae, basi distantes; scapo brevi, 



subcylindrico ; articulo tertio duplo longiore, sequentibus, 



ultimo excepto, gradatim decrescentibus, ultimo elongate. 



Prothorax quadratus, utrinque dentatus. Elytra subangusta, 



apice rotundata. Femora modice clavata ; tarsi omnes 



aequales, articulis tribus basalibus simul subtriangularibus. 



The only species of this genus has the aspect of a small 



Monochamus. The antennae, however, distant at the base, the short 



scape and clavate femora, among other characters, separate it 



from that group. The equal or nearly equal length of all the 



tarsi, and the peculiar form of. the eye, will, one or the other, 



distinguish it from the other genera of this sub-family. The 



anterior acetabula are angulated externally.
