one being short as is usual in the genus; tibiae slender, somewhat 

 compressed, armed with 4 apical spurs, the superior of which are 

 very short, and 5 inferior spines of which i apical and 4 disposed 

 in pairs a little beneath the middle and the apical third of tlie 

 tibia ; tarsi long, compressed, the metatarsus longer than the other 

 articles together, the 3 first joints carinated beneath. Interme- 

 diate legs a little shorter than the anterior ones presenting the 

 same features and armature except the femora which bear two 

 long apical spines.' 



Length of bod\' 22 mm. ; pronot. 7'5 mm. ; width of pronot. 

 7"3 mm.: ant. fem. ly^ mm. ; ant. tib. 19 mm. ; interna, rem. 15 

 mm. ; interm. tib. i6-5 mm. ; process of 7th abd. terg. 4'5 mm. 



This species shows ver}' remarkable characters in the abdom- 

 inal end and also in the antennae; it is to be noted that the 

 special pubescence of these organs is certainly restricted to the 

 male sex, thus showing a link to the much differentiated antennae 

 of the P achyrrhama Br.

Type. — One female from Dawna Hills, Misty Hollow to vSukli, 

 alt. 2100-2590 ft. (F. H. Gravely, 22-24-xi-ii). 



A species remarkable by its large size and chiefly by its stout 

 form and relatively short and thick legs ; colour rather irregularly 

 and probably strongly marbled with brown (the type is much 

 discoloured by a long stay in alcohol) ; face showing 6 longitu- 

 dinal irregular bands; anterior and intermediate femora a little 

 neatl}' annulated, darkened at apex ; posterior femora almost uni- 

 colourous. Pubescence rufous, very caducou.^. 



Head with occiput short, presenting a brown spot behind 

 each eye. Frontal rostrum very narrow and lengthened, furrowed 

 on its whole length but very feebly incised at apex, forming two 

 acute tubercles. Face wide, yellowish, adorned with 6 longitudi- 

 nal, irregular bands, joined to one another in their inferior part. 

 Clypeus very broad, its inferior margin scarcely shorter than the 

 superior one, adorned with two brown spots. Eyes small, much 

 behind the base of antennae ; ocellar spots very neat. Antennae 

 about three times as long as the body, rufous ; ist joint large, 

 cyhndrical, 2nd very short, little swollen in the middle, 3rd al- 

 most twice as long as the 2nd, 4th a little longer than the follow- 

 ing ones. Maxillary palpi long, testaceous, the 3rd and 4th joints 

 not very slender, 5th almost twice as long as 4th (their length 

 being respectively 3'i-3'7 and 7'5 mm.) ; labial palpi rather short, 

 the 3rd joint a little shorter than the other 2 together. 



1 To tell the truth, the specimen described does not bear on the one interme- 

 diate femur remaining more than i internal, long, movable apical spine, the 

 external one being verv short ; but it is e\ ident that this is an anomaly caused by 

 a mutilation before the last moult, this spine being thick and yellowish and not 

 • It all slender .ind brown as the immovable spines of the anterior femora.
