 Java: Buitenzorg; a single specimen. 



Attenuated anteriorly and posteriorly. 



Colour: most of head , first tergite, and part of the second and third, to- 

 gether with the pleurae rufo-castaneous ; the rest of the body including the 

 anterior margin of the head and first tergite green with metallic lustre. 



Head rounded laterally, wider than long, sparsely and feebly punc- 

 tured. Antennae long, composed of twenty-one segments, whereof 

 the basal two are bare, the rest pubescent. Maxillary coxœ with 

 prosternai plates well developed , short , wide, in contact , each furnished 

 with about seven teeth most of which are ill-defined; maxillary feet 

 with conspicuous, sub-dentate basal process. 



Tergites bisulcate from the sixth or seventh, marginate from the 

 tenth or eleventh, with a low nearly obsolete median longitudinal 

 ridge and wrinkled sides. Sternites obsoletely impressed, with two 

 faint abbreviated sulci in front. 



Anal somite; tergite with strongly raised lateral margins, angulate 

 posterior margin , deeply impressed above and behind ; pleurae covered 

 with minute close-set pores, produced into an angular, short, blunt 

 process, armed at its apex with three spines, and with one lateral 

 spine halfway between the apex and the tergite; sternite with rounded 

 converging lateral margins, rounded posterior angles and concave 

 posterior margin; legs long and slender; one femur armed with 2 

 spines, one apical, one median, on the upper-inner edge; 2 on the 

 inner surface and 4 on the infero-external edge; the other has 5 

 smaller spines, arranged in two longitudinal series, on the inner- 

 surface and 5, also smaller, on the infero-external edge; tarsus 

 unarmed, claw spurred. 



The rest of the legs have the claws spurred, and most of them 

 have a spine on the anterior surface of the distal end of the tibia 

 and two distal spines on the first tarsal segment, one anterior and 

 one inferior; (preanal pair of legs absent). 

 Length 60 mm. 



The British Museum has a specimen of this species which was col- 

 lected at mount Salak in Java by Mr. R. Kirkpatrick. 



This specimen has 2 spines, one apical, on the upper inner edge 

 and 6 strong spines in two parallel rows of 3 each on the lower 

 surface of the anal leg.
