358 Dr. J. L. Hancock's Third Paper on the 



short and indistinct, but the rest from the seventh to the terminal 



apical article strongly elongate. Pronotiun anteriorly truncate, 

 posteriorly lengthily acuminate-subulate extended beyond the hind 

 femoral apices; dorsum deplanate, between the shoulders scarcely 



widened; humeral angles substraight, transversely subrounded; 

 median carina pereurrent but low barely elevated; anterior prozonal 

 carinae short and parallel; lateral lobes of pronotum somewhat 

 small, margin anteriorly arcuate; posterior angles turned down 

 and obliquely excised. Elytra small, widened backward, the apices 

 rounded, the central external two-thirds marked with black; wings 

 perfectly explicate, extended barely beyond the pronotal apex. 

 Anterior femora strongly elongate, superior margins little com- 

 pressed basally and serrulate, below entire; middle femora elongate, 

 superior carinae compressed minutely serrulate, and terminating in 

 an apical spine, ventral carinae little compressed subentire or barely 

 undulate; posterior femora slender, superior carinae forward arcuate, 

 posteriorly terminating in distinct antegenicular denticle, very 

 minutely serrulate, genicular apical lobe distinctly produced ; ventral 

 carinae slightly curvate, carinae of external paginae distinct and 

 between them bearing oblique granulate rugae; posterior tibiae 

 narrow, the canthi minutely serrulate and bearing many very small 

 denticles; first and third articles of posterior tarsi equal in length; 

 the third tarsal article distinctly clavate, the three pulvilli of the 

 first tarsal article equal in length and obtuse below. Colour dark 

 cinero-griseous, the hind tibiae infuscate, but light annulate behind 

 the knees. 



Entire length of body, $, 21-2 mm.; pronotum, 138 mm.; 

 posterior femora, (> mm. ; hind tibiae, 5 mm. ; antennae, 6 mm. One 

 example in the author's collection. 



Locality: Padang Pandjang, West Sumatra (Rolle). 



This species is remarkable in the form of the long 

 antennae, produced vertex, globose eyes, and clavate form 

 of the third article of the posterior tarsi. Type in the 

 author's collection. 



Genus THORADONTA, Hancock. 

 Trans. Entom. Soc. London, p. 4<>7, 1908. 



This genus is represented by small forms with sub- 

 quadrate vertex; elongate antennae inserted below the 

 eyes ; the pronotum anteriorly truncate, posteriorly abbre- 

 viated acuminate ; with the median carina of pronotum 

 sinuate or bicristate : dorsum widened between the obtuse
