Longicornia Malayana, 555 



a fine spine, and also to a certain extent in colouration ; 

 in the latter respect, and generally in habit — trusting to 

 recollection — it approaches much more nearly to the 

 Chilian S. pseudocupes than to the Australian species. 



Syllitus alhipennis. 



S. flavo-albescens ; capite prothoraceque ochraceis, 

 nitidis ; scapo, et elytrorum vitta postica externa, 

 nigris; femoribus infumatis; elytris apice spinosis. 



Hob. — Morty. 



Narrow; head and prothorax ochraceous, shining, 

 finely punctured ; elytra spined at their apices, pale yel- 

 lowish-white, coarsely punctured, punctures on the disc 

 irregularly distributed, those on the sides arranged in 

 rows, the shoulder with a black spot, on the side near the 

 outer margin and beginning at the middle a blackish 

 stripe gradually spreading over the apex ; body beneath 

 yellowish, metasternum and abdomen finely pubescent; 

 femora and tibiae more or less smoky-black ; scape of the 

 antennse black, shining, rest of the joints yellowish, all 

 except the last three or four very hairy beneath in the 

 male. 



Length 5^ lines. 



Lepturin^. 



This subfamily, as limited by M. Lacordaire, is one of 

 the largest and most natural of all the Gerambycidce. The 

 species, which abound in the temperate parts of the 

 Northern hemisphere, are easily recognized by their 

 peculiar habit, due in great part to the head being pro- 

 longed behind into a neck. They are found chiefly on 

 flowers, and do not appear to be very active. The 

 tropical species are comparatively few in number, but 

 doubtless many more remain to be discovered, especially 

 in the Malayan region; there is no evidence as yet of 

 their being found in Australia. Mr. Wallace^s collection 

 contains two undoubted species of Leptura, and I have 

 seen another species from Penang; there are also repre- 

 sentatives of three purely Malayan forms. A fourth 

 Malayan genus {Asilaris, Pasc.) is known, but does not 

 appear in the collection.
