232 Longicornia Malayana. 



quinto brevioribus, illo ad apicem, boc in medio, nodosis ; 

 caeteris cylindiicis, quinto eequalibus vel paulo longioribus, 

 sed ultimo praecedente longiore ; ( ? ) corpori vix aequales, 

 articulo quarto solo nodoso. Protlwrax fere sequatus ( $ 

 sub-transversus), basi bi-sinuatus, utrinque in medio spi- 

 nosus. Elytra paulo depressa, lateribus apicem versus sen- 

 sim angustioribus, postice rotundata, humeris normalibus. 

 Pedes elongati, praesertim antici ; femora robusta, fusiformia ; 

 libke anticae {$) elongatae, intus dente valido armatee, ( !g ) 

 modice elongatae, muticae ; tarsi antici dilatati { $). Proster- 

 ??«/« sub-elevatum. Mesosternum productuni. 

 These characters are drawn up from the three species collected 

 by Mr. Wallace. A nearly allied genus from Penang (0/»oc?/nM«) 

 differs in the oblong prothorax, the altered proportions of the 

 joints of the antennae, and the fourth and fifth being thickened 

 throughout in both sexes, the third also in the female is nodose at 

 the apex : in addition it has the shoulders produced as in 

 Otar'ionomus and Achthophora. So far as the individuals I have 

 seen can be relied on, the males of 7'. Saundersii and 7'. tristis are 

 smaller than the females, but this is reversed in T. Chevrolati. All 

 the species have numerous glossy-black granulations of varying 

 size on the basal part of their elytra, as well as a broad white 

 band on the cheeks, sides of the prothorax, and sterna. A 

 female specimen from Batchian, which I cannot refer to any of the 

 above, although it approaches T. tristis, has the scutellum equila- 

 terally triangular, not broadly truncate, or broadly rounded, as in 

 the other species.

Covered with a pale ashy pubescence, the elytra with small, 

 more or less confluent, spots of black and white; head with a 

 well marked mesial groove, scarcely punctured except on the 

 vertex, a broad pure white line beginning in a small point at the 

 base o{ the eye, and continued along the sides to the posterior 

 margin of the metasternum ; prothorax finely corrugated, the
