Longicornia Malayana. 39 



Prolhorax subtransversus, lateribus rotiindatis, spina basin 



versus instructus. Elytra oblonga, Integra. Femora clavata. 



Tarsi antici triangulares, intermedii et postici angustati, vix 



subelongati. Corpus baud setosum. 

 The unusual length of the third and fourth antennal joints 

 (bringing the fifth to the apex of the elytra) is the principal 

 character of this genus, which, in other respects, approaches 

 jEgocidnus (post, p. 40), except that the pubescence is opaque 

 and not silvery. The two species differ principally in colour, but 

 the scutellum of M. marmorea is very decidedly transverse. 



Micenia marmorea. (PI. III. fig. 6.) 



M. brunnea, rufo-grisea variegata. 



Hah. — Salwatty. 



Reddish-brown, varied with large patches of reddish-grey ; 

 head with a uniform greyish pile, distinctly punctured ; eyes and 

 mandibles black ; prothorax slightly subtransverse, reddish- 

 brown, greyish at the sides, coarsely punctured; scutellum short, 

 broadly transverse ; elytra rather coarsely punctured, dark 

 reddish-brown, a large irregular patch at the shoulder, extending 

 nearly to the middle, another at the apex and partially connected 

 with the first by a smaller central patch, all greyish tinged with 

 red ; body beneath dark luteous ; legs and antennae luteous, the 

 latter darker towards the apex and more than twice as long as 

 the body. 



Length 2 lines. 



The anterior acetabula in this species are more nearly entire 

 than in any other species of this sub-family that I have seen. 



Miania irrorata. 



M. fusca, cinereo-irrorata. 



Hab. — Batchian. 



Dark brown, with a short opaque pubescence ; head very dis- 

 tinctly punctured ; eyes large, black, approximating on the 

 vertex ; prothorax subtransverse, coarsely punctured, dark 

 brown, the sides and centre with ashy patches ; scutellum slightly 

 pointed behind ; elytra very strongly punctured, dark brown, 

 sprinkled with small, distant, but not very distinct, patches of 

 ashy ; body beneath, legs, and antennae dark brown, the latter 

 a shade lighter, and rather more than twice as long as the body. 



Length 2 lines. 



The following species differs from Micenia in having the 

 antennae considerably shorter, although the third and fourth
