APPENDIX 



Head extremely finely and sparingly punctured, clypeus not separated from the face, 

 except at the sides, transverse, sparingly punctured at the base, antennae fulvous, the terminal 

 six joints black, widened, thorax strongly transverse, the sides feebly rounded, the surface 

 strongly but not closely punctured, except at the sides, where the punctuation is stronger than 

 at the disc, and more closely placed, elytra not wider at the base than the thorax, rather strongly 

 punctured in closely approached rows, below and the legs black, the femora unarmed, abdomen 

 fulvous. 



Habitat. Bukit Besar. 3,000 to 3,500 feet. Jungle. 5th May, 1901. 



Of this species, well-distinguished by its colouration from other Eastern Colaspoides, two 

 apparently female specimens were obtained. 



Colaspoides siamensis, sp. nov. 



Cupreous or greenish, the antennae and legs fulvous, under side nearly black, thorax sub- 

 remotely punctured on the disc, elytra deeply and closely punctate-striate at the inner dise^ 

 the sides coarsely punctured and the interstices strongly confluently rugose, femora unarmed. 



Length, 4-435 mm. 



Head impunctate at the vertex, the middle with a fovea, epistome subquadrate, separated 

 from the face by lateral grooves, supra-ocular sulci distinct, clypeus with some distinct punctures, 

 its anterior margin nearly straight, labrum fulvous, antennae long and slender, fulvous, the 

 terminal three joints piceous, third and two following joints equal, thorax not more than twice 

 as broad as long, narrowed anteriorly, the sides feebly rounded, the disc rather strongly and 

 subremotely punctured, the sides more closely so, scutellum impunctate, broad, elytra not 

 depressed below the base, strongly punctured in semiregular rows at the inner disc, the sides 

 much more coarsely so and the interstices at the same place strongly transversely and confluently 

 convex, below bluish-black, the last abdominal segment fulvous at the apex. 



Habitat. Biserat, Jalor. Jungle. 4th July, 190 1. 



There are a good many Eastern species of Colaspoides known which seem closely allied to 

 the present insect, this may however be separated by the colour of the antennae and legs, in 

 connexion with the unarmed femora, the strongly punctured thorax and its shape and the 

 nearly black under side ; the two specimens before me seem to represent the male sex. 



Hyphasis fulvicornis, sp. nov. 

 Flavous or fulvous, thorax impunctate, sides strongly rounded, elytra extremely minutely 

 punctured, widened at the middle. 

 Length, 5 mm. 



Head impunctate, frontal elevations broad, strongly raised, carina acute, elongate, antennae 

 extending to the middle of the elytra, fulvous, the basal joint elongate, thickened, third joint 

 slightly shorter than the fourth, terminal joints elongate, thorax strongly transverse, more than 

 twice as broad as long, the lateral margins strongly rounded, sides narrowly flattened and 

 reflexed, the surface impunctate, with a slight depression in front of the scutellum ; elytra 

 widened towards the middle, microscopically punctured, metatarsus of the posterior legs as long 

 as the following two joints, claws strongly swollen. 



Habitat. K. Mabek, Jalor (Robinson and Annandale), also Perak (my collection.)
