242 SUMATRAN COLEOPTERA. 



females. — The type-specimen of this species is a male. 

 The female has been described by Dr. Gestro (Ann. Mus. 

 Civ. Gen. 1879. p. 10) under the name of Macronota 

 sumatrana. — Both sexes were also found by Mr. Schagen 

 van Leeuwen at Kotta Zuydewijn. 



5. Pseudochalcothea virens Rits. (= Bockii Lansb.). — 

 One male and two females. — The female alone was known 

 up to this date: Sumatra-Expedition, Singkarah ; van Lans- 

 berge, Ajer Mantjoer; Schagen van Leeuwen, Solok; Dr. 

 Klaesi, Padang. The male differs from it (besides by the 

 common sexual differences , viz. narrower shape, longer 

 antennal club , longitudinally impressed abdomen) by having 

 elongate tarsi, slender and elongate unarmed front tibiae, 

 slightly curved middle tibiae, and hind tibiae which are feebly 

 curved (the concavity on the outer side) and provided on the 

 middle of the inner side with a compressed and acutely pointed 

 curved appendage , which is obliquely directed inwards and 

 backwards and reaches to the end of the tibia. Moreover the 

 inner apical spur of this pair of tibiae is subacute, not 

 broadly truncate at the apex as is the case in the female. 

 Finally the sutural notch at the end of the elytra and the 

 impression at the end of the pygidium is deeper, and the 

 apical ventral segment is shorter and nearly impunctate. — 

 The shape of the mesosternal process seems to be not quite 

 constant in this species , at least in my Loeboe Raja spe- 

 cimens it is prolonged at the tip and consequently more 

 acute with feebly sinuate sides; moreover the tibiae and 

 tarsi in these specimens are not bright coppery but green 

 with a faint golden hue on the upper side, and the palpi 

 and antennae are dark piceous with metallic green tinges 

 in stead of bright reddish brown. 



6. Campsosternus rosicolor Hope var. ? — One specimen. 



7. Ananca spec. — A very mutilated specimen of a large cin- 

 namon coloured species which has the legs slightly infuscate. 



8. Chloridolum Klaesii Rits. — A single female specimen. — 

 This species seems to be somewhat variable as to the sculp- 

 ture of the head and pronotum. On the former the double
