The presence of a series of maculatus from the Province of Kwang- 

 Tung, China, in a recently received collection, indicates that this 

 is probably the most abundant species of Conocephalus in that 

 region. As Walker's description agrees in all respects with this 

 material we feel justified in indicating the above synonymy. 



Mount Banahao, Luzon, Philippine Islands, (from C. F. Baker), 



1 9. 



Mount Makiling, Luzon, Philippine Islands, (from C. F. Baker), 



2 cf. 



Singapore, British Straits Settlements, (from C. F. Baker), 1 cf , 

 1 9. 



Island of Penang, British Straits Settlements, (from C. F. Baker), 

 1 9. 



In addition to the suffused and interrupted brown band between 

 the median and ulnar veins of the tegmina, this species is distinctive 

 in having the limbs thickly supplied with flecks of mummy brown. 

 The tegmina are not heavily marked in any of the present series, 

 the specimens from Mount Makiling being so recessive that the 

 tegminal suffusions are weakly defined. All are macropterous, 

 with tegmina extending slightly beyond the apices of the caudal 

 femora. 



Conocephalus (Xiphidion) laetus (Redtenbacher) 



1891. Xiphidium laetum Redtenbacher, Verh. Zool.-bot. Ges. Wien,XLI, 

 p. 514, pi. IV, fig. 87. [ 9 , northern Australia.] 



Mount Makiling, Luzon, Philippine Islands, (from C. F. Baker), 

 1 9. 



Zamboanga, Mindanao, Philippine Islands, (from C. F. Baker), 

 1 cf. 



Obi Island, Moluccas, 1 cf , 1 9 . 



The Philippine material differs from the original description in 

 lacking the dorsal brown stripe of head and pronotum, the Moluccan 

 pair in being decidedly larger. These specimens agree so closely 

 in all other features that we feel fully justified in considering them 

 conspecific. 



We note the following features, not mentioned by Redtenbacher. 

 The antennae appear closely and minutely subannulate, rather 

 than "remote fusco-annulatae." The ovipositor shows a very 

 faintly sigmoid tendency and is broader than normal in the genus; 

 thus of the same type as in the Japanese C. gladiatus (Redten- 

 bacher), but much less elongate. Genicular lobes of caudal femora 

 strongly bispinose. Caudal tibiae distad with dorso-internal spur
